NOTE 1—ORGANIZATION AND DESCRIPTION OF BUSINESS

Y‑mAbs Therapeutics, Inc. (“we,” “us,” “our,” the “Company,” or “Y‑mAbs”) is a late-stage clinical biopharmaceutical company focused on the development and commercialization of novel antibody-based therapeutic products for the treatment of cancer.

We have entered into a worldwide license and research collaboration agreement (the “MSK License Agreement”) with Memorial Sloan‑Kettering Cancer Center (“MSK”), under which we have obtained the exclusive rights to MSK’s rights to two clinical stage antibody‑based product development programs for the treatment of neuroblastoma and other oncology indications. The MSK License Agreement also includes a protein Multimerization Platform Technology—MULTI TAGTM, and an option to obtain the rights to certain chimeric antigen receptor T‑cell, or CAR‑T, technologies, as well as rights to certain next‑generation humanized, affinity matured bispecific antibodies.

The Company is headquartered in New York and was incorporated on April 30, 2015 under the laws of the State of Delaware.

NOTE 2—BASIS OF PRESENTATION

The Company has not generated any revenue and has incurred losses since inception. Operations of the Company are subject to certain risks and uncertainties, including, among others, uncertainty of drug candidate development; technological uncertainty; uncertainty regarding patents and proprietary rights; uncertainty in obtaining FDA approval in the United States and regulatory approval in other jurisdictions; marketing or sales capability or experience; uncertainty in getting adequate payer coverage and reimbursement; and dependence on key personnel, compliance with government regulations and the need to obtain additional financing. Drug candidates currently under development will require significant additional research and development efforts, including extensive preclinical and clinical testing and regulatory approval, prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel infrastructure and extensive compliance‑reporting capabilities.

The Company’s drug candidates are in the development stage. There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s intellectual property will be obtained, that any products developed will obtain necessary government regulatory approval or that any approved products will be commercially viable. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will generate significant revenue from product sales. The Company operates in an environment of rapid change in technology and substantial competition from pharmaceutical and biotechnology companies.

The Company’s financial statements have been prepared on the basis of continuity of operations, realization of assets and the satisfaction of liabilities in the ordinary course of business. The Company has experienced negative cash flows and had an accumulated deficit of $100.8 million as of March 31, 2019 and $84.8 million as of December 31, 2018. Through March 31, 2019, the Company has funded its operations through proceeds from sales of shares of its common stock, including its initial public offering, or IPO, in September 2018. As of March 31, 2019, the Company had cash and cash equivalents of $134.2 million, and as of December 31, 2018 the Company had cash and cash equivalents of $147.8 million. As of the issuance date of the quarterly financial statements for the three months ended March 31, 2019, the Company expects that its cash and cash equivalents at March 31, 2019 will be sufficient to fund its operating expenses and capital expenditure requirements through at least the next twelve months. The future viability of the Company, until such time that the Company has commercialized any of its products, is dependent on its ability to raise additional capital to finance its operations.

The Company may be required to raise additional capital to fund future operations through the sale of its equity securities, incurring debt, entering into licensing or collaboration agreements with partners, grants or other sources of financing. Sufficient funds may not be available to the Company at all or on attractive terms when needed from equity or debt financing. If the Company is unable to obtain additional financing from these or other sources when needed, or to the extent needed, it may be necessary to significantly reduce its current rate of spending through delaying, scaling back, or suspending certain research and development programs and other operational goals.

The accompanying unaudited consolidated financial statements reflect the accounts of the Company and its wholly‑owned subsidiary and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information, Accounting Standards Codification (ASC) Topic 270-10 and with the instructions to Form 10-Q. Accordingly, these financial statements do not include all of the information and notes required by GAAP for complete financial statements. The unaudited interim financial statements include all adjustments (consisting only of normal recurring nature) necessary in the judgment of management for a fair statement of the results for the periods presented. All intercompany balances and transactions have been eliminated. The Company has evaluated subsequent events through the date of this filing.  Operating results for the three-month period ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ended December 31, 2019, any other interim periods, or any future year or period. The December 31, 2018 consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP.  You should read these unaudited interim condensed consolidated financial statements in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

NOTE 3—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Our critical accounting policies are detailed in our Annual Report on Form 10-K for the year ended December 31, 2018. Effective January 1, 2019, the Company adopted Accounting Standards Update No. 2018-09 (“ASU 2018-09”), Codification Improvements, which clarify, correct errors in, or make minor improvements to a variety of ASC topics;  ASU No. 2018‑07, Compensation—Stock Compensation (Topic 718), Improvements to Nonemployee Share‑Based Payment Accounting; Accounting Standards Update No. 2018‑02, (“ASU 2018-02”), Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income; and Accounting Standards Update No. 2016‑02 (“ASU 2016‑02”), Leases. Other than the adoption of the new accounting guidance, our critical accounting policies have not changed materially from December 31, 2018.

Operating Leases

As described below, the Company adopted Topic 842 as of January 1, 2019. The Company determines if an arrangement includes a lease at inception. Operating lease right-of-use assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the net present value of lease payments, the Company uses its estimated incremental borrowing rate based on information available at the lease commencement date. Because most of the Company’s leases do not provide an implicit rate of return, an incremental borrowing rate is used based on the information available at the commencement date in determining the present value of lease payments on an individual lease basis. The Company’s incremental borrowing rate for a lease is the estimated rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms.

The Company’s leases may include options to extend or terminate the lease which are included in the lease term when it is reasonably certain that it will exercise any such options. None of the Company’s leases contain any residual value guarantees. Lease expense is recognized on a straight-line basis over the expected lease term. Related variable lease costs incurred are not material to the Company. The Company does not recognize right-of-use assets or related lease liabilities with a lease term of twelve months or less on our consolidated balance sheet.

Topic 842 also provides practical expedients and certain exemptions for an entity’s ongoing accounting post implementation. The Company currently elected the short-term lease recognition exemption for all leases that qualify.

This means, for those leases that qualify, we will not recognize right-of-use assets or liabilities, and this includes not recognizing right-of-use assets or liabilities for existing short-term leases of those assets in transition. We also elected the practical expedient to not separate lease and non-lease components for all of our leases. The Company has made an accounting policy election to account for each separate lease component of a contract and its associated non-lease components as a single lease component. See the Lease Agreements section in Note 6 for the related disclosures.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Significant estimates and assumptions reflected in these financial statements include, but are not limited to, the accrual for research and development expenses, the accrual of milestone and royalty payments, and the valuation of stock options. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.

Segment Information

The Company is engaged solely in the discovery and development of novel antibody-based therapeutic products for the treatment of cancer. Accordingly, the Company has determined that it operates in one operating segment.

Recently Issued Accounting Pronouncements - Adopted

In August 2018, the Securities Exchange Commission (“SEC”) adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders’ equity for interim financial statement. Under the amendments, an analysis of changes in each caption of stockholders’ equity presented in the balance sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed.  The Company’s first presentation of changes in stockholders’ equity as required under the new SEC guidance was included in its Form 10-Q for the three-month period ended March 31, 2019.

In July 2018, the FASB issued Accounting Standards Update No. 2018-09 (“ASU 2018-09”), Codification Improvements, which clarify, correct errors in, or make minor improvements to a variety of ASC topics.  The changes in ASU 2018-09 are not expected to have a significant effect on current accounting practices. Some of the amendments in this update do not require transition guidance and will be effective upon this update. However, many of the updates do have transition guidance with effective dates for periods beginning after December 15, 2018.  The adoption of this standard on January 1, 2019 did not have a material impact on our consolidated financial statements and related disclosures.

In June 2018, the FASB issued ASU No. 2018‑07, Compensation—Stock Compensation (Topic 718), Improvements to Nonemployee Share‑Based Payment Accounting (“ASU 2018‑07”). ASU 2018‑07 is intended to simplify aspects of share‑based compensation issued to non‑employees by making the guidance consistent with the accounting for employee share‑based compensation. ASU 2018‑07 is required to be adopted for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this standard on January 1, 2019 did not have a material impact on our consolidated financial statements and related disclosures.

In February 2018, the FASB issued Accounting Standards Update No. 2018‑02, (“ASU 2018-02”), Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018‑02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. ASU 2018‑07 is required to be adopted for annual periods beginning after

December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this standard on January 1, 2019 did not have a material impact on our consolidated financial statements and related disclosures.

In February 2016, the FASB issued Accounting Standards Update No. 2016‑02 (“ASU 2016‑02”), Leases, which is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018 with early adoption permitted. Under ASU 2016‑02, lessees will be required to recognize for all leases, at the commencement date of the lease, a lease liability, which is a lessee’s obligation to make lease payments arising from a lease measured on a discounted basis, and a right‑to‑use asset, which is an asset that represents the lessee’s right to use or control the use of a specified asset for the lease term. Topic 842 was subsequently amended by ASU 2017-13, Revenue and Leases: Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments; ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; ASU No. 2018-11, Targeted Improvements and ASU No. 2018-20, Narrow Scope Improvements for Lessors.

The Company adopted the new leasing standards using the modified retrospective transition approach as of January 1, 2019, with no restatement of prior periods or cumulative adjustment to retained earnings. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. The Company used the effective date as our date of initial application.  Consequently, financial information was not updated and the disclosures required under the new standard are not provided for dates and periods before January 1, 2019.  The new standard also provides a number of optional practical expedients in transition. The Company elected the package of practical expedients, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs.

Upon adoption of the new leasing standards, the Company recognized a lease liability of $1.8 million and a related right-of-use asset of $1.5 million with the difference being due to the elimination of previously reported deferred rent. The Company subsequently entered into two new lease agreements during the three months ended March 31, 2019, and recognized an incremental lease liability and related right-of-use asset of $0.9 million.

Recently Issued Accounting Pronouncements – Not Yet Adopted

In August 2018, the FASB issued Accounting Standards Update No. 2018-15 (“ASU 2018-15”), Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. ASU 2018-15 clarifies certain aspects of ASU 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, which was issued in April 2015. Specifically, ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years with early adoption permitted. The Company is currently evaluating the impact its adoption may have on its consolidated financial statements.

 

 

 

 

NOTE 4—NET LOSS PER SHARE

Basic net loss per share (“EPS”) is calculated by dividing net income or loss attributable to common stockholders by the weighted average common stock outstanding. Diluted EPS is calculated by adjusting weighted average common shares outstanding for the dilutive effect of common stock options and restricted stock units. In periods in which a net loss is recorded, no effect is given to potentially dilutive securities, since the effect would be antidilutive. Securities that could potentially dilute basic EPS in the future were not included in the computation of diluted EPS because to do so would have been antidilutive. The calculations of basic and diluted net loss per share are as follows:

Potentially dilutive securities excluded from the computation of diluted earnings per share relate to stock options outstanding and unvested RSUs and totaled 3,388,169 shares as of March 31, 2019 and 2,219,000 shares as of March 31, 2018.

NOTE 5—ACCRUED LIABILITIES

Accrued short‑term liabilities at March 31, 2019 and December 31, 2018 are as follows:

 

 

NOTE 6—LICENSE AGREEMENTS AND COMMITMENTS

The Company has entered into two license agreements and certain other agreements with MSK. The license agreements are further described below as the MSK License Agreement and the CD33 License Agreement. These license agreements with MSK grant the Company certain patent rights and intellectual property rights. In consideration of obtaining the patent rights and intellectual property rights, the Company agreed to make certain payments and issue shares of the Company’s common stock to MSK. Certain of the payments are contingent milestone and royalty payments, the terms of which are further described below. Amounts disclosed in the consolidated balance sheets for accrued milestone and royalty payments are inclusive of obligations under the MSK License Agreement and CD33 License Agreement, collectively.

MSK License Agreement

On August 20, 2015, we entered into the MSK License Agreement that grants us a worldwide, sublicensable license to MSK’s rights to certain patent rights and intellectual property rights related to certain know‑how to develop, make, and commercialize licensed products and to perform services for all therapeutic and diagnostic uses in the field of cancer diagnostics and cancer treatments.

The patents and patent applications covered by this agreement are directed, in part, to naxitamab, an anti GD2 antibody, and omburtamab, which is an anti B7‑H3 antibody, as well as affinity matured versions of these certain antibodies and certain single chain variable fragments (Fv) constructs, and their use for immunotherapy, targeting the treatment of neuroblastoma, diffuse intrinsic pontine glioma (DIPG), osteosarcoma and other oncology indications. Upon entering into the MSK License Agreement in 2015 and in exchange for the licenses, we paid MSK an upfront payment, issued 1,428,500 shares of our common stock to MSK and agreed to provide certain anti‑dilution rights to MSK. In addition, we are required to pay to MSK certain royalty and milestone payments. We expensed the upfront payment and the issuance of shares to MSK in 2015. We also recorded expense related to common stock issued related to certain anti‑dilution rights held by MSK.

The MSK License Agreement requires us to pay to MSK mid to high single digit royalties based on annual net sales of licensed products or the performance of licensed services by us and our affiliates and sublicensees. We are obligated to pay annual minimum royalties of $80,000 over the royalty term, commencing on the fifth anniversary of the license agreement. These amounts are non‑refundable but are creditable against royalty payments otherwise due under the MSK License Agreement. Total expensed minimum royalty payments in 2016 under the MSK License Agreement were $1,200,000, upon determination that the payment of such minimum royalties was probable and the amount was estimable in 2016. The accrued minimum royalties were recorded as long‑term accrued liabilities as of March 31, 2019 and December 31, 2018. We are also obligated to pay MSK certain clinical, regulatory and sales‑based milestone payments under the MSK License Agreement. Certain of the clinical and regulatory milestone payments become due at the earlier of completion of the related milestone activity or the date indicated in the MSK License Agreement. Total clinical and regulatory milestones potentially due under the MSK License Agreement are $2,450,000 and $9,000,000, respectively. There are also sales‑based milestones that become due should the Company achieve certain amounts of sales of licensed products resulting from the license arrangement with MSK, with total sales‑based milestones potentially due of $20,000,000. The Company records milestones in the period in which the contingent liability is probable and the amount is reasonably estimable. In addition, to the extent we enter into sublicense arrangements, we are obligated to pay to MSK a percentage of certain payments that we receive from sublicensees of the rights licensed to us by MSK, which percentage will be based upon the achievement of certain clinical milestones. The Company has not entered into any sublicenses related to the MSK License Agreement. Failure by the Company to meet certain conditions under the arrangement could cause the related license to such licensed product to be canceled and could result in termination of the entire arrangement with MSK. In addition, the Company may terminate the MSK License Agreement with prior written notice to MSK.

No milestones were expensed in the three months ended March 31, 2019 or 2018. As of March 31, 2019, $150,000 of accrued milestone obligations were recorded in accrued short term liabilities and $300,000 was recorded within long-term liabilities. As of December 31, 2018, $875,000 of accrued milestone obligations were recorded in accrued short term liabilities and $300,000 was recorded within long-term liabilities. These milestone‑related charges were recorded as research and development expense in 2016, upon determination that payment of these clinical milestone obligations was probable after satisfying the financing requirements described herein.

Research and development is inherently uncertain and as described above, should such research and development fail, the MSK License Agreement is cancelable at the Company’s option. The Company also considered the development risk and each party’s termination rights under the agreement when considering whether any regulatory‑based milestone payments, certain of which also contain time‑based payment requirements, were probable. Given the uncertainty associated with research and development and the Company’s ability to cancel the MSK License Agreement, such regulatory‑based obligations were determined not to be probable as of March 31, 2019 and December 31, 2018 and therefore have not been accrued.

CD33 License Agreement

On November 13, 2017, we entered into an exclusive license agreement for certain MSK rights in connection with certain CD33 antibodies, which we refer to as the CD33 License Agreement. The CD33 License Agreement obligates us to pay to MSK mid to high single digit royalties based on annual net sales of licensed products or the performance of licensed services by us and our affiliates and sublicensees. We are obligated to pay annual minimum

royalties of $40,000 over the royalty term, increasing to $60,000 once a patent within the licensed rights is issued, and commencing on the tenth anniversary of the CD33 License Agreement. These amounts are non‑refundable but are creditable against royalty payments otherwise due under the CD33 License Agreement. We are also obligated to pay MSK certain fees under a sponsored research agreement under the CD33 License Agreement. In addition, milestone payments become due upon achievement of the related clinical, regulatory or sales‑based milestone defined in the CD33 License Agreement. Certain of the clinical and regulatory milestone payments become due at the earlier of completion of the related milestone activity or the date indicated in the CD33 License Agreement. Total potential clinical and regulatory milestones potentially due under the CD33 License Agreement are $550,000 and $500,000, respectively. There are also sales‑based milestones that become due should the Company achieve certain amounts of sales of licensed products resulting from the CD33 License Agreement with MSK, with total sales‑based milestones potentially due of $7,500,000. Failure by the Company to meet certain conditions under the CD33 License Agreement could cause the related license to such licensed product to be canceled and could result in termination of the arrangement with MSK. In addition, the Company may terminate the CD33 License Agreement with prior written notice to MSK. The Company records milestones in the period in which the contingent liability is probable and the amount is reasonably estimable. In addition, to the extent we enter into sublicense arrangements, we are obligated to pay to MSK a percentage of certain payments that we receive from sublicensees of the rights licensed to us by MSK, which percentage will be based upon the achievement of certain clinical milestones. The Company has not entered into any sublicenses related to the CD33 License Agreement.

No milestones were expensed in the three months ended March 31, 2019 or 2018. None of the clinical milestone obligations previously accrued were paid in the three months ended March 30, 2019 or 2018, and the total amount accrued in prior periods of $550,000 was recorded as accrued long‑term liabilities as of March 31, 2019 and December 31, 2018. These milestone‑related charges were recorded as research and development expense in 2017. Research and development is inherently uncertain and as described above, should such research and development fail, the CD33 License Agreement is cancelable at the Company’s option. The Company considered risks as well as each party’s termination rights under the CD33 License Agreement when considering whether any regulatory‑based milestone payments and minimum royalty payments, certain of which also contain time‑based payment requirements, were probable. Given the uncertainty associated with research and development and the Company’s ability to cancel the CD33 License Agreement, such obligations were determined not to be probable as of March 31, 2019 and December 31, 2018 and therefore have not been accrued.

MabVax sublicense agreement

On June 27, 2018, we entered into a sublicense agreement with MabVax Therapeutics Holding, Inc (“MabVax”) pursuant to which MabVax has sublicensed to the Company certain of MabVax’s patent rights and know-how for development and commercialization of products for the prevention or treatment of neuroblastoma by means of administering a bi-valent ganglioside vaccine, granted to MabVax pursuant to an exclusive license agreement between MabVax and MSK. Under the sublicense agreement, the Company has paid a license fee of $700,000 to MabVax and will pay an additional $600,000 at the first anniversary of the sublicense agreement. The initial license fee of $700,000 was expensed and paid upon execution of the agreement and the continuation fee of $600,000 was accrued in the fourth quarter of 2018. The Company has agreed to become solely responsible for future amounts payable to MSK and to handle other of MabVax’ obligations applicable to the licensed indication towards MSK. This includes the obligation to pay development milestones totaling $1,400,000 and mid-single-digit royalty payments to MSK. Research and development is inherently uncertain and as described above, should such research and development fail, the MabVax sublicense agreement is cancelable at the Company’s option. The Company considered risks as well as each party’s termination rights under the MabVax sublicense agreement when considering whether any milestone payments and minimum royalty payments were probable. Given the uncertainty associated with research and development and the Company’s ability to cancel the MabVax sublicense agreement, such obligations were determined not to be probable as of March 31, 2019 and December 31, 2018 and therefore have not been accrued.

Other agreements

On November 5, 2015, we entered into a sponsored research agreement, which we refer to as the SRA, with MSK pursuant to which we agreed to pay MSK to provide research services over a period of five years related to the intellectual property licensed under the MSK License Agreement. For the three-month periods ended March 31, 2019 and 2018, we incurred research and development expenses of $306,000 and $297,000, respectively, under the SRA.

On March 20, 2016, we entered into a master data services agreement, which we refer to as the MDSA, with MSK pursuant to which we committed to provide make certain payments in exchange for services provided by approximately two full time employees at MSK, who are engaged in transferring clinical data, databases, regulatory files and other know‑how included in the MSK License Agreement to the Company. On October 1, 2018 the MDSA was amended to increase the resources to approximately five full time employees. During the three months ended March 31, 2019 and 2018, we incurred expenses of $171,000 and $106,000, respectively, under the MDSA.

On June 21, 2017, we entered into a master clinical trial agreement, which we refer to as the CTA, with MSK pursuant to which we committed to fund certain clinical trials at MSK. Under the MSK License Agreement, the funding of clinical activities is limited to a five-year period. During the three months ended March 31, 2019 and 2018, we incurred expenses of $853,000 and $1,631,000, respectively, under the CTA.

On June 27, 2017, we entered into two separate core facility service agreements, which we refer to as the CFAs, with MSK pursuant to which we committed to obtaining certain laboratory services from MSK. During the three months ended March 31, 2019 and 2018, we incurred expenses of $219,000 and $114,000, respectively, under the CFAs.

On November 13, 2017, we entered into a CD33‑sponsored research agreement, which we refer to as the CD33‑SRA, with MSK pursuant to which we agreed to pay MSK to provide research services over a period of two years related to the intellectual property licensed under the CD33 License Agreement. During the three months ended March 31, 2019 and 2018, we incurred research and development expenses of $174,000 and $167,000, respectively, under the CD33‑SRA.

Lease Agreements

In February 2019, the Company entered into a lease agreement in connection with its 4,500 square feet laboratory in New Jersey. The term of the lease is three years from the date the Company begins to occupy the premises, with an option to extend for an additional two years which the Company expects to exercise and has included in the determination of the related lease liability. Fixed rent payable under the lease is approximately $144,000 per annum and is payable in equal monthly installments of approximately $12,000.

In January 2018, the Company entered into a lease agreement in connection with its corporate headquarters in New York. The term of the lease is five years from the date the Company begins to occupy the premises. Fixed rent payable under the lease is approximately $384,000 per annum and is payable in equal monthly installments of approximately $32,000.

Additionally, the Company entered into a three‑year lease agreement for the lease of certain office space in Denmark in February 2018, as amended in November 2018 and February 2019. The lease is payable in monthly installments of approximately $19,000. Until the end of March 2018, the Company, maintained a lease for certain office space in Denmark as further described in Note 9, Related Party Transactions.

As described above in Note 3, the Company adopted Topic 842 as of January 1, 2019. Prior period amounts have not been adjusted and continue to be reported in accordance with the Company’s historical accounting under Topic 840.

Operating lease costs were $141,000 and $45,000 for the three months ended March 31, 2019 and 2018, respectively. During the three months ended March 31, 2019, the expenses were recorded as $97,000 in research and

development expense and $44,000 in general and administrative expense. During the three months ended March 31, 2018, the expenses were all recorded in general and administrative expense. Cash paid for amounts included in the measurement of lease liabilities for the three months ended March 31, 2019 was $32,000 and was included in net cash used in operating activities in the Company’s Consolidated Statements of Cash Flows.

Future minimum commitments under all non-cancelable operating leases are as follows:

 

Operating lease liabilities are based on the net present value of the remaining lease payments over the remaining lease term. In determining the present value of lease payments, the Company uses its estimate of its incremental borrowing rate based on the information available at the lease commencement date. As of March 31, 2019, the weighted average remaining lease term is 4.6 years and the weighted average discount rate used to determine the operating lease liability was 11.0%.

NOTE 7—STOCKHOLDERS’ EQUITY

Authorized Stock

As of March 31, 2019 and December 31, 2018, the Company has authorized a total of 105,500,000 shares, 100,000,000 of which are common stock, par value $0.0001 per stock, and 5,500,000 of which are preferred stock, par value $0.0001 per share.

Common Stock

Each share of common stock is entitled to one vote. Common stockholders are entitled to receive dividends, as may be declared by the board of directors, if any, subject to preferential dividend rights of the preferred stock, none of which have been issued. The Company had issued 34,193,666 shares of its common stock as of March 31, 2019 and December 31, 2018.

Preferred Stock

Preferred stock may be issued from time to time in one or more series with such designations, preferences and relative participating, optional or other special rights and qualifications, limitations or restrictions as approved by the Company’s Board of Directors. No preferred stock has been issued as of March 31, 2019 or December 31, 2018.

Stock grant agreements with non‑employees

In August 2015, we entered into certain stock grant agreements with non‑employees of the Company. We agreed to issue a total of 2,800,000 shares to two non‑employee researchers who were involved in the development of technology licensed from MSK in consideration for their prior service. These two researchers were employees of MSK. The shares are released according to a vesting schedule. A total of 560,000 shares were issued in 2015, and a total of 448,000 shares issued in each of 2016 and 2017. In 2018 a total of 448,000 shares were issued to the two researchers, and upon completion of the IPO we issued an additional 96,000 shares. The issuance was made pursuant to a stock grant agreement and did not result in proceeds to the Company. A total of 400,000 shares are to be issued in each of 2019 and 2020 to one non-employee physician, subject to certain conditions, such that the total grant will have been issued. The total award was expensed at its estimated fair value in 2015, as no future service was required to continue to vest in and receive the shares of common stock. In August 2016, the Company repurchased and retired a total of 83,600 shares from the two non‑employees of the Company at an amount equal to the estimated fair value of $4.38 per share. The transaction reduced the Company’s shareholders’ equity by $366,000.

In April 2018, the Company granted 72,373 common stock options to a non‑employee physician employed by MSK under our 2015 Equity Incentive Plan (the 2015 Plan). The options become exercisable over a four‑year period, with the first twenty‑five percent (25%) exercisable twelve (months) from the date of grant and the remainder becoming exercisable ratably each month over the three years thereafter. The contractual term of the option award is 10 years from the date of grant. The total award was expensed at its estimated fair value in April 2018, as no future service was required by the non‑employee to continue to vest in the option grant. The shares will become immediately exercisable upon the occurrence of a change in control, as defined in the 2015 Plan as further described in Note 8, Share-Based Compensation.

Issuance of common stock

In September 2018, we completed an initial public offering and issued 6,900,000 shares of Common Stock at a purchase price of $16.00 per share for an aggregate consideration of $99,507,000, net of issuance costs. Upon completion of the IPO we also issued 96,000 shares of our common stock. The issuance was made pursuant to a stock grant agreement and did not result in proceeds to the Company.

In August 2018, we issued 448,000 shares of our common stock. The issuance was made pursuant to stock grant agreements and did not result in proceeds to the Company.

In addition, the number of shares available for issuance under the 2018 Plan will also include an annual increase on the first day of each fiscal year beginning in 2019, equal to 4% of the outstanding shares of common stock as of the last day of our immediately preceding fiscal year. The exercise price of options granted under the plans must at least be equal to the fair market value of our common stock on the date of grant. The term of an incentive stock option may not exceed 10 years, except that with respect to any participant who owns more than 10% of the voting power of all classes of our outstanding stock, the term must not exceed five years and the exercise price must equal at least 110% of the fair market value on the grant date. The administrator will determine the methods of payment of the exercise price of an option, which may include cash, shares or other property acceptable to the administrator, as well as other types of consideration permitted by applicable law. Options granted under the 2018 Plan vest according to the schedule specified in the grant agreements, which is generally a four year period and generally become immediately exercisable upon the occurrence of a change in control, as defined.

Stock Option Valuation

During the three month periods ended March 31, 2019 and 2018, stock based compensation for stock option grants were $848,000 and $172,000 respectively for options granted to employees and directors. During the three months ended March 31, 2019, the expenses were recorded as $145,000 in research and development expense and $703,000 in

general and administrative expense. During the three months ended March 31, 2018, the expenses were recorded as $59,000 in research and development expense and $113,000 in general and administrative expense.

The following table summarizes common stock options issued and outstanding:

The weighted average fair value of stock options granted to employees for the three month period ended March 31, 2019 was $12.88. No options were granted during the three month period ended March 31, 2018.

The aggregate intrinsic value of stock options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common stock for those stock options that had exercise prices lower than the fair value of the Company’s common stock.

As of December 31, 2018, we had $10,848,000 of unrecognized compensation related to employee stock options that are expected to vest over a period of 2.82 years. As of March 31, 2019, we had $10,258,000 of unrecognized compensation related to employee stock options that is expected to vest over a period of 2.76 years.

Restricted Stock Unit Activity

During the three-month period ended March 31, 2019, stock-based compensation for restricted stock unit grants was $16,000. During the three months ended March 31, 2019, the expenses were recorded as $14,000 in research and development expense and $2,000 in general and administrative expense. There was no stock based compensation for restricted stock units during the three months ended March 31, 2018.

The following table summarizes restricted stock units issued and outstanding:

 

As of March 31, 2019, we had $222,000 of unrecognized compensation related to employee restricted stock units that are expected to vest over a period of 2.80 years.

NOTE 9—RELATED PARTY TRANSACTIONS

MSK is a shareholder of the Company and under the MSK License Agreement, the CD33 License Agreement, CTA, CFAs, SRA and MDSA, we have expensed costs in the total amount of $1,723,000 and $2,316,000 in the three months ended March 31, 2019 and 2018, respectively, for milestones, minimum royalties, research and development costs and patent activities. Please refer to Note 6 for additional details on our various agreements with MSK. As of March 31, 2019 and December 31, 2018, we had a total of $4,175,000 and $4,475,000, respectively, recorded as accounts payable and accrued liabilities related to amounts due to MSK.

In July 2016, the Company entered into a lease agreement with a shareholder of the Company, Weco Group, in connection with the subsidiary in Denmark. The lease payable thereunder is approximately $4,000 per month and, as the lease can be terminated with three months’ notice, any future rent commitment thereunder will amount to approximately $12,000. The lease terminated in April 2018, when the Company moved to a new third‑party lease. In addition, the Company has reimbursed Weco Group for certain administrative expenses. The total expenses, including rent, equaled $25,000 during the three months ended March 31, 2018. No similar expenses were incurred during the three months ended March 31, 2019.

NOTE 10—INCOME TAXES

The Company provided no current and deferred income taxes on net losses of $15,934,000 and $7,483,000 for the three month periods ended March 31, 2019 and 2018, respectively.

The Company recognizes income tax benefits for tax positions determined more likely than not to be sustained upon examination, based on the technical merits of the positions. As of March 31, 2019 and December 31, 2018, the Company has determined that there were no uncertain tax positions. The Company’s tax returns for years 2017, 2016, and 2015 are open for tax examination by U.S. federal and state, and the Danish tax authorities.

The valuation allowance related primarily to net U.S. deferred tax assets from operating losses, research and development tax credit carryforwards, and acquired intangibles.

The Company maintains a full valuation allowance on its U.S. and foreign deferred tax assets. The assessment regarding whether a valuation allowance is required considers both positive and negative evidence when determining whether it is more‑likely‑than‑not that deferred tax assets are recoverable. In making this assessment, significant weight is given to evidence that can be objectively verified. In its evaluation, the Company considered its cumulative loss in recent years and its forecasted losses in the near‑term as significant negative evidence. Based upon review of available positive and negative evidence, the Company determined that the negative evidence outweighed the positive evidence and a full valuation allowance on its U.S. and foreign deferred tax assets will be maintained. The Company will continue to assess the realizability of its deferred tax assets and will adjust the valuation allowance as needed.

NOTE 11—OTHER BENEFITS

The Company has established a retirement program for employees of our Danish subsidiary pursuant to which all such employees can contribute an amount at their election from their base compensation and may receive contributions from our Danish subsidiary. Contributions from our Danish subsidiary were immaterial during the three months ended March 31, 2019 and 2018. In addition, health insurance benefits for our Danish employees are fully paid for by such employees. Our Danish subsidiary does not incur any costs for these health insurance benefits.

On October 1, 2018, the Company adopted a defined contribution 401(k) savings plan (the 401(k) plan) covering all U.S. employees of the Company.  Participants may elect to defer a percentage of their pretax or after-tax compensation to the 401(k) plan, subject to defined limitations. The plan allows for a discretionary match by the Company. The Company made no matching contributions to the plan during the three months ended March 31, 2019 and 2018.

 

Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our accompanying financial statements and related notes thereto included elsewhere in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2018 on file with the SEC. Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report on Form 10-Q, including information with respect to our plans and strategy for our business and related financing, includes forward‑looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Quarterly Report on Form 10-Q, our actual results could differ materially from the results described in or implied by the forward‑looking statements contained in the following discussion and analysis. For convenience of presentation some of the numbers have been rounded in the text below.

Overview

We are a late‑stage clinical biopharmaceutical company focused on the development and commercialization of novel, antibody‑based therapeutic products for the treatment of cancer. We have a broad and advanced product pipeline, including two pivotal‑stage product candidates—naxitamab and omburtamab—which target tumors that express GD2 and B7‑H3, respectively. We are developing naxitamab for the treatment of pediatric patients with relapsed or refractory, or R/R, high‑risk neuroblastoma, or NB, and radiolabeled omburtamab for the treatment of pediatric patients with central nervous system, or CNS, leptomeningeal metastases, or LM, from NB. NB is a rare and almost exclusively pediatric cancer that develops in the sympathetic nervous system and CNS/LM is a rare and usually fatal complication of NB in which the disease spreads to the membranes, or meninges, surrounding the brain and spinal cord in the CNS.

We expect to submit a Biologic License Application or BLA for each of our two lead product candidates in 2019, with a goal of receiving approval by the U.S. Food and Drug Administration, or FDA in 2020. We plan to commercialize both of our lead product candidates in the United States as soon as possible after obtaining FDA approval, if such approval occurs. Additionally, we have two omburtamab follow‑on product candidates in pre‑clinical development, omburtamab‑DTPA (diethylenetriamine pentaacetate) and huB7‑H3, a humanized version of omburtamab, each targeting indications with large adult patient populations. 

We have initiated a Phase I trial with our huGD2 bispecific antibody, or BsAb, for the treatment of refractory GD2 positive adult and pediatric solid tumors, thereby addressing large patient populations. We are also advancing a pipeline of novel BsAbs through late pre‑clinical development, including our huCD33‑BsAb product candidate for the treatment of hematological cancers expressing CD33, a transmembrane receptor expressed on cells of myeloid lineage. We believe our BsAbs have the potential to result in improved tumor‑binding, longer serum half‑life and significantly greater T‑cell mediated killing of tumor cells without the need for continuous infusion. Our mission is to become the world leader in developing better and safer antibody‑based pediatric oncology products addressing clear unmet medical needs and, as such, have a transformational impact on the lives of patients. We intend to advance and expand our product pipeline into certain adult cancer indications either independently or in collaboration with potential partners.

Since our inception in April 2015, we have devoted substantially all of our resources to organizing and staffing our company, business planning, identifying potential product candidates, conducting pre‑clinical studies of our product candidates and clinical trials of our lead product candidates, raising capital, and acquiring and developing our technology platform among other matters. We do not have any products approved for sale and have not generated any revenues from product sales.

To date, we have financed our operations primarily through private placements of our securities and the proceeds of our initial public offering. On September 25, 2018, we completed the initial public offering, or IPO, of our common stock pursuant to which we issued and sold 6,900,000 shares at a price to the public of $16.00 per share which included the exercise in full of the underwriters’ option to purchase additional shares for gross proceeds of approximately $110.4 million, before deducting underwriting discounts and commissions and estimated offering expenses.  We have received aggregate gross proceeds of approximately $230.0 million through March 31, 2019 from the sale and issuance of our common stock.

As of March 31, 2019, we had an accumulated deficit of $100.8 million. Our net losses were $15.9 million and $7.5 million for the three months ended March 31, 2019 and 2018, respectively. We have incurred significant net operating losses in every year since our inception and expect to continue to incur increasing net operating losses and significant expenses for the foreseeable future. Our net losses may fluctuate significantly from quarter to quarter and year to year. We anticipate that our expenses will increase significantly as we:

We believe that our cash on hand will be sufficient to fund our operations and capital expenditures through the fourth quarter of 2020. We do not expect to generate revenues from product sales unless and until we successfully complete development and obtain regulatory approval for a product candidate, which is subject to significant uncertainty and may never occur. Although no assurance can be given, our goal is to complete the development of our lead product candidates, naxitamab for the treatment of pediatric R/R high‑risk NB, and omburtamab for the treatment of CNS/LM from NB, by the end of 2019. Additionally, we currently use Contract Research Organizations or CROs and Contract Manufacturing Organizations or CMOs to carry out our pre‑clinical and clinical development activities and we do not yet have a sales organization.

Moreover, pursuant to the MSK License, we have obtained exclusive rights to MSK’s rights in our current product candidates. Under the MSK License, we have committed to funding scientific research and conducting certain clinical trial activities at MSK through 2020. As these product candidates progress through clinical development, regulatory approval and commercialization, certain milestone payments will come due either as a result of the milestones having been met or the passage of time even if the milestones have not been met. Also, we will owe MSK customary royalties on commercial sales of our approved products, including a fixed minimum royalty starting in 2020 whether or not product sales are ever achieved. In addition, we have committed to obtain certain personnel and laboratory services at MSK under our MDSA, and two separate CFAs. Also, under our CTA with MSK, we will provide drug product and funding for certain clinical trials at MSK. These MSK agreements are important to our business. For a more detailed discussion of the terms and conditions of these agreements, see note 6 “License Agreements and Commitments.”

If we obtain regulatory approval for our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Accordingly, we may continue to fund our operations through public or private equity or debt financings or other sources, including strategic collaborations. We may, however, be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements as and when needed would have a negative impact on our financial condition and our ability to develop our current product candidates, or any additional product candidates, if developed. Because of the numerous risks and uncertainties associated with the development of our existing product candidates and any future product candidates, our platform and technology and because the extent to which we may enter into collaborations with third parties for development of any of our product candidates is unknown, we are unable to estimate the amounts of increased capital outlays and operating expenses associated with completing

the research and development of our product candidates. If we raise additional funds through collaborations, strategic alliances, or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs, product candidates or grant licenses on terms that may not be favorable to us and could have a negative impact on our financial condition.

Components of Our Results of Operations

Revenue

To date, we have not generated any revenue from product sales and do not expect to do so in the near future. We expect that we will experience increasing losses as we continue our development of, and seek regulatory approvals for, our product candidates and begin to commercialize any approved products. Our ability to generate revenue for each product candidate for which we receive regulatory approval, if any, will depend on numerous factors, including reimbursement, coverage, competition, commercial manufacturing capability and market acceptance of such approved products.

Operating Expenses

Research and Development Expenses

Research and development expenses consist of expenses incurred in connection with the discovery and development of our product candidates. We expense research and development costs as incurred. These expenses include:

The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the remainder of the development of naxitamab and omburtamab or any future product candidates we may develop. This uncertainty is due to

the numerous risks and uncertainties associated with the duration and cost of clinical trials, which vary significantly over the life of a project as a result of many factors, including:

Our expenditures are subject to additional uncertainties, including the terms and timing of regulatory approvals. We may never succeed in achieving regulatory approval for naxitamab, omburtamab or any other product candidates we may develop.

A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials beyond those that we anticipate will be required for the completion of clinical development of a product candidate, or if we experience significant delays in our clinical trials due to patient enrollment or other reasons, we would be required to expend significant additional financial resources and time on the completion of clinical development.

Research and development activities are central to our business model. Product candidates in later stages of clinical development, like naxitamab and omburtamab, generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later‑stage clinical trials. We expect our research and development expenses to increase significantly over the next several years as we increase personnel costs, including stock‑based compensation, conduct clinical trials and potentially prepare regulatory filings for naxitamab and omburtamab.

General and Administrative Expenses

General and administrative expenses consist primarily of employee related expenses, including salaries, bonus, benefits, and stock‑based compensation expenses for personnel in executive, finance and administrative functions. Other significant costs include facility costs not otherwise included in research and development expenses, legal fees relating to corporate matters, and fees for patent, accounting, tax, and consulting services.

We anticipate that our general and administrative expenses will increase in the future to support continued research and development activities, potential commercialization of our product candidates and increased costs associated with operating as a public company, including expenses related to services associated with maintaining compliance with exchange listing and the SEC requirements, regulatory expenses, director and officer insurance costs and investor and public relations costs. These increases will likely include increased costs related to the hiring of additional personnel and fees to outside consultants, lawyers and accountants, among other expenses. Additionally, if and when we believe a regulatory approval of a product candidate appears likely, we anticipate an increase in payroll and other employee‑related expenses as a result of our preparation for commercial operations, especially as it relates to the sales and marketing of that product candidate.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which we have prepared in accordance with U.S. generally accepted accounting principles, or GAAP. We believe that several accounting policies are significant to understanding our historical and future performance. We refer to these policies as critical because these specific areas generally require us to make judgments and estimates about matters that are uncertain at the time we make the estimate, and different estimates—which also would have been reasonable—could have been used. On an ongoing basis, we evaluate our estimates and judgments, including those described in greater detail below. We base our estimates on historical experience and other market‑specific or other relevant assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in the notes to our financial statements appearing elsewhere in this Quarterly Report on Form 10-Q, we believe the following accounting policies to be most critical to the judgments and estimates used in the preparation of our financial statements.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Significant estimates and assumptions reflected in these financial statements include, but are not limited to, the accrual for research and development expenses, the accrual of milestone and royalty payments, the valuation of shares of common stock and stock options. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.

Research and Development Expenses

Research and development costs are charged to operations when incurred and are included in operating expenses. Research and development costs consist principally of compensation cost for our employees and consultants that perform our research activities, the fees paid to maintain our licenses, the payments to third parties for manufacturing and clinical research organizations and additional product development, and consumables and other materials used in research and development. We record accruals for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities, we analyze progress of the studies or clinical trials, including the phase or completion of events, invoices received and contracted costs. Actual results could differ from our estimates. We are

obligated to make certain milestone and royalty payments in accordance with the contractual terms of the MSK License based upon the resolution of certain contingencies. Certain of these milestone payments are due and payable with the passage of time whether or not the milestones have actually been met. We record the milestone and royalty payment when the achievement of the milestone (including the passage of time) or payment of the milestone or royalty is probable and the amount of the payment is reasonably estimable.

Income Taxes

We account for income taxes under the asset and liability approach for the financial accounting and reporting of income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to net operating loss carry forwards and temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. These assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which the temporary differences are expected to reverse. A valuation allowance is established when management determines that it is more likely than not that some portion or all of the deferred tax assets will not be realized.

We prepare and file tax returns based on its interpretation of tax laws and regulations. In the normal course of business, our tax returns are subject to examination by various taxing authorities. Such examinations may result in future tax and interest assessments by these taxing authorities. In determining our tax provision for financial reporting purposes, we establish a reserve for uncertain tax positions unless such positions are determined to be more likely than not of being sustained upon examination based on their technical merits. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. Accordingly, we will report a liability for unrecognized tax benefits resulting from any uncertain tax positions taken or expected to be taken on a tax return.

Our policy is to recognize, when applicable, interest and penalties on uncertain tax positions as part of income tax expense.

Stock‑Based Compensation

We measure stock options and restricted share units granted to employees and directors based on the fair value on the date of the grant and recognize compensation expense of those awards, over the requisite service period, which is the vesting period of the respective award. Forfeitures are accounted for as they occur. We issue stock options and restricted share units to employees and directors with only service‑based vesting conditions and record the expense for these awards using the straight‑line method over the requisite service period.

For share‑based awards granted to non‑employees prior to January 1, 2019, compensation expense is recognized over the period during which services are rendered by such non‑employees until completed. At the end of each financial reporting period prior to completion of the service, the fair value of these awards is remeasured using the then‑current fair value of our shares of common stock and updated assumption inputs in the Black‑Scholes option‑pricing model. No share-based awards were granted to non-employees after December 31, 2018.

The fair value of each stock option grant is estimated on the date of grant using the Black‑Scholes option pricing model. Historically, we have been a private company and lack company‑specific historical and implied volatility information for our shares. Therefore, we estimate our expected share price volatility based on the historical volatility of a group of publicly‑traded peer companies and we expect to continue to do so until such time as we have adequate historical data regarding the volatility of our own traded share price. The expected term of our stock options has been determined utilizing the “simplified” method for awards as we have limited historical data to support the expected term assumption. The expected term of stock options granted to non‑employees is equal to the contractual term of the option award. The risk‑free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield is based on the fact that we have never paid cash dividends on shares of our common stock and do not expect to pay any cash dividends in the foreseeable future.

Results of Operations

Comparison of the Three Months Ended March 31, 2019 and 2018

The following table summarizes our results of operations for the three months ended March 31, 2019 and 2018:

Research and Development Expenses

We do not record our research and development expenses on a program‑by‑program or on a product‑by‑product basis as they primarily relate to personnel, research, manufacturing, license fees, non‑cash expense in connection with equity issuances to strategic partner and consumable costs, which are simultaneously deployed across multiple projects under development. These costs are included in the table below.

Research and development expenses increased by $6.3 million from $6.2 million for the three months ended March 31, 2018, to $12.5 million for the three months ended March 31, 2019. This was primarily due to a $4.3 million increase in outsourced manufacturing expenses for our lead product candidates, naxitamab and omburtamab. In addition, expenses for outsourced research and supplies increased by $1.3 million for the three months ended March 31, 2019, due to our increased need for clinical trial support. Employee-related costs including salary, benefits and non-cash stock-based compensation for personnel related to our research activities, increased by $0.9 million for the three months ended March 31, 2019, due to our expanding workforce.

General and Administrative Expenses

General and administrative expenses increased by $2.5 million, from $1.3 million for the three months ended March 31, 2018, to $3.7 million for the three months ended March 31, 2019. The increase in general and administrative expenses was primarily attributable to a $1.4 million increase in employee related costs, including salary, benefits and non-cash stock-based compensation for personnel related to our business activities. In addition, costs for setting up commercial infrastructure increased by $0.3 million for the three months ended March 31, 2019. The increase in general

and administrative expenses overall primarily relates to the infrastructure and administrative costs of becoming a public company.

Interest and Other Income (Expense)

Other income for the three months ended March 31, 2019 was $319,000 as compared to other expenses of $4,000 for the three months ended March 31, 2018. Our interest income has not been significant due to low interest earned on our cash balances.

Liquidity and Capital Resources

Overview

Since our inception we have incurred significant net operating losses and expect to continue to incur increasing net operating losses and significant expenses for the foreseeable future. Our net losses may fluctuate significantly from quarter to quarter and year to year. We do not currently have any approved products and have never generated any revenue from product sales. We have financed our operations through March 31, 2019 primarily through gross proceeds of approximately $230.0 million from the sale of our common stock, including the completion of our IPO on September 25, 2018, in which we issued and sold 6,900,000 shares of our common stock at a public offering price of $16.00 per share, resulting in gross proceeds of approximately $110.4 million before deducting underwriters discounts, commissions and estimated offering costs.

As of March 31, 2019, we had cash and cash equivalents of approximately $134.2 million. We believe that our cash on hand will be sufficient to fund our operations and capital expenditures through the fourth quarter of 2020.

The Company may be required to raise additional capital to fund future operations through the sale of its equity securities, incurring debt, entering into licensing or collaboration agreements with partners, grants or other sources of financing. Sufficient funds may not be available to the Company at all or on attractive terms when needed from equity or debt financing. If the Company is unable to obtain additional financing from these or other sources when needed, or to the extent needed, it may be necessary to significantly reduce its current rate of spending through delaying, scaling back, or suspending certain research and development programs and other operational goals.

Cash Flows

The following table provides information regarding our cash flows for the three months ended March 31, 2019 and 2018:

Net Cash Used in Operating Activities

The use of cash in all periods resulted primarily from our net losses adjusted for non-cash charges and changes in components of working capital. Net cash used in operating activities was $13.5 million for the three months ended March 31, 2019, as compared to $6.6 million for the three months ended March 31, 2018. The $6.9 million increase in net cash used in operations was primarily due to an increase of $8.5 million in our net loss for the three months ended

March 31, 2019. This increase was primarily due to our operational expenses in connection with the development of our lead product candidates, naxitamab and omburtamab, and the expansion of our other business activities. Non-cash expenses also included stock-based compensation to employees, which increased by $0.7 million.

Net Cash Used in Investing Activities

Net cash used in investing activities was $126,000 for the three months ended March 31, 2019, as compared to no investment activities for the three months ended March 31, 2018. The $126,000 increase in net cash used in investing activities was primarily caused by investment in laboratory equipment and furniture for our new facilities.

Net Cash Provided by Financing Activities

There were no financing activities during the three months ended March 31, 2019. Net cash used in financing activities was $1.6 million during the three months ended March 31, 2018, which related to the payment of offering costs.

Funding Requirements

We expect our expenses to increase in connection with our ongoing activities, particularly as we complete clinical development of our lead product candidates, naxitamab and omburtamab, and potentially initiate our planned BLA submissions for both product candidates. In addition, we plan to advance the development of other pipeline programs, initiate new research and pre-clinical development efforts and seek marketing approval for any additional product candidates that we successfully develop. If we obtain marketing approval for any of our product candidates, we expect to incur commercialization expenses, which may be significant, related to establishing sales, marketing, manufacturing capabilities, distribution and other commercial infrastructure to commercialize such products. Furthermore, we expect to incur additional costs associated with operating as a public company. Accordingly, we might need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs and/or future commercialization efforts.

We believe that our existing cash and cash equivalents as of March 31, 2019, will enable us to fund our operating expenses and capital expenditure requirements through the fourth quarter of 2020. We have based our projections of operating capital requirements on assumptions that may prove to be incorrect and we may use all of our available capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with the development and commercialization of naxitamab and omburtamab, and the research, development and commercialization of other potential product candidates, we are unable to estimate the exact amount of our operating capital requirements. The amount and timing of our future capital requirements will depend on many factors, including:

Identifying potential product candidates and conducting pre-clinical studies and clinical trials is a time-consuming, expensive and uncertain process that takes many years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success.

Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all. Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest in our company may be materially diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If we raise funds through additional collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Off‑Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off‑balance sheet arrangements, as defined under the applicable regulations of the SEC.

Contractual Obligations and Commitments

A summary of our minimum contractual obligations related to our material outstanding contractual commitments is included in Note 6 of our enclosed financial statements.

We enter into contracts in the normal course of business with CROs, CMOs, clinical sites and other third parties for clinical trials, pre-clinical research studies and testing, professional consultants for expert advice and other vendors for clinical supply, manufacturing and other services. These contracts are not considered contractual obligations, as they provide for termination upon prior notice, and, therefore, are cancelable contracts and do not include any minimum purchase commitments.

Payments due upon cancellation consist only of payments for services provided or expenses incurred, including non-cancellable obligations of our service providers, up to the date of cancellation. These payments are not included in the table of contractual obligations and commitments. As further described below, under various licensing and related agreements with third parties, we have agreed to make milestone and royalty payments to third parties.

We have not included the contingent payment of certain milestones, which timing cannot be determined because they are not date certain. In addition, we have other contingent payment obligations, such as such as royalties or other third-party milestones, which are not included in the table above as the amount, timing and likelihood of such payments are not known. We have entered into two license agreements and certain other agreements with MSK. The license agreements are further described below as the MSK License and the MSK CD33 License. Under the MSK License and MSK CD33 License we are obligated to (i) make certain payments to MSK, which become due based upon the achievement of the related milestone activities or the passage of time in the event such milestone activities are not achieved, as well as certain sales related milestones, (ii) pay mid to high single-digit royalties to MSK, on a product-by-product and country-by-country basis, of a mid-to-high single-digit royalties based on net sales of products licensed under the applicable agreement and (iii) pay to MSK a percentage of any sublicense fees received by us. Under the MSK License, we are also obligated to pay annual minimum royalties of $80,000 over the royalty term, starting in 2020. Under the MSK CD33 License, we are obligated to pay annual minimum royalties of $40,000 over the royalty term beginning in 2027, increasing to $60,000 once a patent within the licensed rights is issued. These amounts are non-refundable but are creditable against royalty payments otherwise due under the respective agreements. Total expensed minimum royalty payments in 2016 under the MSK License were $1,200,000, upon determination that the payment of such minimum royalties was probable and the amount was estimable in 2016. We are also obligated to pay MSK certain clinical, regulatory and sales-based milestone payments under the MSK License and MSK CD33 License. Certain of the clinical and regulatory milestone payments become due at the earlier of completion of the related milestone activity or the date indicated in the MSK License.

Total clinical, regulatory and sales-based milestones potentially due under the MSK License are $2,450,000, $9,000,000 and $20,000,000, respectively. In addition, under the MSK CD33 License, we are obligated to make potential payments of $550,000, $500,000 and $7,500,000 for clinical, regulatory and sales-based milestone, respectively. We record milestones in the period in which the contingent liability is probable and the amount is reasonably estimable.

Research and development is inherently uncertain and, should such research and development fail, the MSK License and MSK CD33 License are cancelable at our option. We have also considered the development risk and each party’s termination rights under the two license agreements when considering whether any contingent payments, certain of which also contain time-based payment requirements, were probable. In addition, to the extent we enter into sublicense arrangements, we are obligated to pay to MSK a percentage of certain payments that we receive from sublicensees of the rights licensed to us by MSK, which percentage will be based upon the achievement of certain clinical milestones. To date, we have not entered into any sublicenses related to the MSK License or MSK CD33 License. Our failure to meet certain conditions under such arrangements could cause the related license to such licensed product to be canceled and could result in termination of the entire respective arrangement with MSK. In addition, we may terminate the MSK License or MSK CD33 License with prior written notice to MSK. No milestones were expensed during the three months ending March 31, 2019 or March 31, 2018.

On June 27, 2018, we entered into a sublicense agreement, the MabVax Sublicense, with MabVax Therapeutics Holdings, Inc., or MabVax, pursuant to which MabVax granted us all of the exclusive rights granted to MabVax under its license agreement with MSK, or the MabVax-MSK License, for a bi-valent ganglioside-based vaccine intended to treat NB, or the NB vaccine. MSK originally developed the NB vaccine and licensed to MabVax as part of a portfolio of

anti-cancer vaccines. Under the terms of the MabVax Sublicense, we paid MabVax an upfront payment of $700,000, and, if we decide to move forward with the development of the vaccine, we have agreed to make an additional payment of $600,000 on the first anniversary of the Mabvax Sublicense, provided that no notice of termination has been made by us before such date. We will also be responsible for any potential downstream payment obligations to MSK related to the NB vaccine that were specified in the MabVax-MSK license agreement. This includes the obligation to pay development milestones totaling $1,400,000 and mid-single-digit royalty payments to MSK. In addition, if we obtain FDA approval for the NB vaccine, then we are obligated to file with the FDA for a PRV. If the PRV is granted and subsequently sold, MabVax will receive a percentage of the proceeds from the sale thereof. The Mabvax Sublicense will terminate upon the termination or expiration of the MabVax-MSK License.

Recent Accounting Pronouncements

Refer to Note 3, “Summary of Significant Accounting Policies,” in the accompanying notes to the consolidated financial statements for a discussion of recent accounting pronouncements.

Emerging Growth Company Status; The JOBS Act

The JOBS Act permits an “emerging growth company” such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. We have irrevocably elected to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards when they are required to be adopted by public companies that are not emerging growth companies.

For so long as we are an emerging growth company, we expect that:

We will remain an emerging growth company for up to five years, although we will cease to be an “emerging growth company” upon the earliest of: (i) the last day of the fiscal year following the fifth anniversary of our initial public offering, (ii) the last day of the first fiscal year in which our annual gross revenues are $1.07 billion or more, which amount is periodically updated, (iii) the date on which we have, during the previous rolling three‑year period, issued more than $1.0 billion in non‑convertible debt securities or (iv) the date on which we are deemed to be a “large accelerated filer” as defined in the Exchange Act.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk

We are exposed to market risk related to changes in interest rates. As of March 31, 2019 and December 31, 2018, we had cash and cash equivalents of $134.2 million and $147.8 million, respectively, maintained primarily with

financial institutions in federally insured accounts. We currently have, and may, from time to time in the future, cash in banks in excess of FDIC insurance limits. We have not experienced any losses to date resulting from this practice. We mitigate our risk by maintaining the majority of our cash and equivalents with high quality financial institutions.

Our exposure to changes in the general level of U.S. interest rates is considered immaterial, particularly because our cash equivalents are primarily held in day-to-day bank accounts. Due to short-term nature of such balances, an immediate 100 basis point change in interest rates would not have any effect on the fair market value of cash balances.

Foreign Currency Exchange Risk

Our primary exposure to market risk is foreign exchange rate sensitivity to the Danish Kroner (DKK), the currency used in the Kingdom of Denmark, where our wholly owned subsidiary, Y-mAbs Therapeutics A/S, is located. As of March 31, 2019, we had cash and cash equivalents denominated in DKK of $0.9 million, and an immediate 5% change in DKK exchange rate would not have any material effect on the fair market value of cash balances with the subsidiary.

Item 4.  Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated, as of the end of the period covered by this Quarterly Report, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a‑15(e) and 15d‑15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective at the reasonable assurance level as of March 31, 2019, due to material weaknesses in our internal control over financial reporting.

In designing and evaluating our disclosure controls and procedures (as defined in Rules 13a‑15(e) and 15d‑15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act), management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting, (as defined in Rules 13a‑15(f) and 15d‑15(f) under the Exchange Act) during the quarter ended March 31, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Internal Control

We will be required, pursuant to Section 404(a) of the Sarbanes-Oxley Act, or Section 404, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting in our annual report for the year ended December 31, 2019 to be filed with the SEC. This assessment will need to include disclosure of any material weaknesses identified by management over our internal control over financial reporting. However, our independent registered public accounting firm will not be required to report on the effectiveness of our internal control over financial reporting pursuant to Section 404(b) until the later of the year following our first annual report required to be filed with the SEC, or the date we are no longer an “emerging growth company” if we take advantage of the exemptions contained in the JOBS Act.

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with GAAP. Prior to our initial public offering, we were a private company and we are currently planning a process for reviewing, documenting and testing our internal control over financial reporting. Certain material weaknesses have been identified in our internal

control over financial reporting. A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. We are in the very early stages of the costly and challenging process of planning the activities necessary to perform the evaluation needed to comply with Section 404.

In connection with the audit of our financial statements for the years ended December 31, 2017 and 2018, it was determined that we lack a sufficient number of trained professionals with an appropriate level of accounting knowledge, training and experience to: (a) design and maintain formal accounting policies, procedures and controls over the fair presentation of our financial statements; (b) analyze, record and disclose complex accounting matters timely and accurately, including share-based compensation arrangements and accounting for license arrangements; and (c) design and maintain controls over the preparation and review of account reconciliations, journal entries and financial statements, including maintaining appropriate segregation of duties.

Each of these control deficiencies could result in a misstatement of these accounts or disclosures that would result in a material misstatement of our annual or interim consolidated financial statements that would not be prevented or detected, and accordingly, it was determined that these control deficiencies constitute material weaknesses. See the section herein entitled “Risk Factors—It has been determined that we have material weaknesses in our internal control over financial reporting. If our remediation of these material weaknesses is not effective, or if we experience additional material weaknesses or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock. In addition, because of our status as an emerging growth company, our independent registered public accounting firm is not required to provide an attestation report as to our internal control over financial reporting for the foreseeable future.” If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired. If we are unable to remediate these identified material weaknesses, or if we experience additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls, we may not be able to accurately or timely report our financial condition or results of operations, or comply with the accounting and reporting requirements applicable to public companies, which may adversely affect investor confidence in us and, as a result, the value of our common stock.

We have not performed an evaluation of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act, nor have we engaged an independent registered public accounting firm to perform an audit of our internal control over financial reporting as of any balance sheet date or for any period reported in our financial statements. Presently, we are not an accelerated filer, as such term is defined by Rule 12b-2 of the Exchange Act, and therefore, our management is not presently required to perform an annual assessment of the effectiveness of our internal control over financial reporting. This requirement will first apply to our second Annual Report on Form 10-K. Our independent public registered accounting firm will first be required to attest to the effectiveness of our internal control over financial reporting for our Annual Report on Form 10-K for the first year we are no longer an “emerging growth company.”

We are in the very early stages of the costly and challenging process of compiling the system and processing documentation necessary to perform the evaluation needed to comply with Section 404. We may not be able to complete our evaluation, testing or any required remediation in a timely fashion. During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal controls are designed and operating effectively, which could result in a loss of investor confidence in the accuracy and completeness of our financial reports. This could cause the price of our common stock to decline, and we may be subject to investigation or sanctions by the SEC.

Emerging Growth Company Status; The JOBS Act

The JOBS Act permits an “emerging growth company” such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies until those standards would

otherwise apply to private companies. We have irrevocably elected to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards when they are required to be adopted by public companies that are not emerging growth companies.

For so long as we are an emerging growth company and qualify as a smaller reporting company, we expect that:

·        we will present only two years of audited financial statements, in addition to any required unaudited financial statements, with correspondingly reduced Management’s Discussion and Analysis of Financial Condition and Results of Operations disclosure as long as we continue to qualify as a smaller reporting company;

·        we will avail ourselves of the exemption from the requirement to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding a supplement to the auditor’s report providing additional information about the audit and the financial statements;

·        we will avail ourselves of the exemption from the requirement to obtain an attestation and report from our auditors on the assessment of our internal control over financial reporting pursuant to the Sarbanes‑Oxley Act; and

·        we will provide less extensive disclosure about our executive compensation arrangements.

We will remain an emerging growth company for up to five years, although we will cease to be an “emerging growth company” upon the earliest of: (i) the last day of the fiscal year following the fifth anniversary of our initial public offering, (ii) the last day of the first fiscal year in which our annual gross revenues are $1.07 billion or more, which amount is periodically updated, (iii) the date on which we have, during the previous rolling three‑year period, issued more than $1.0 billion in non‑convertible debt securities or (iv) the date on which we are deemed to be a “large accelerated filer” as defined in the Exchange Act. 

PART II - OTHER INFORMATION

Item 1.  Legal Proceedings.

From time to time, we may become involved in legal proceedings arising in the ordinary course of our business. We are not currently subject to any material legal proceedings.

Item 1A.  Risk Factors.

Our business is subject to numerous risks. You should carefully consider the risks and uncertainties described below together with all of the other information contained in this Quarterly Report on Form 10-Q, including our financial statements and the related notes, and in our other filings with the SEC. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that affect us. If any of the following risks occur, our business, financial condition, results of operations and future growth prospects could be materially and adversely affected. In such event, the trading price of our common stock could decline and you might lose all or part of your investment.

Risks Related to Our Financial Condition and Need for Additional Capital

We have a limited operating history and have incurred significant losses since inception. We have no products approved for commercial sale and we expect to incur significant losses for the foreseeable future. We may never achieve or maintain profitability, which may cause the market value of our common stock to decline significantly.

We are a clinical-stage biopharmaceutical company with a limited operating history. Since our inception in 2015, we have incurred significant losses each year. As of March 31, 2019, we had an accumulated deficit of $100.8 million. We have financed our operations principally through private placements and the initial public offering of our common stock. To date, we have devoted substantially all of our efforts to research and development of our lead product candidates. While our lead product candidates are in pivotal clinical trials, we cannot assure you that we will receive regulatory approval for the sale of these or other product candidates in the near term, if at all. Our other product candidates are in the early stages of clinical development or pre-clinical research. As a result, we expect that it will be a number of years, if ever, before we have any of these other product candidates approved and ready for commercialization.

We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future. The net losses we incur may fluctuate significantly from quarter to quarter. We have no product candidates approved for commercial sale, have not generated any revenue from product sales, and do not anticipate generating any revenue from product sales until sometime after we receive regulatory approval for the commercial sale of a product candidate. We cannot assure you that we will ever receive regulatory approval for any of our product candidates. Our ability to generate revenue and achieve profitability depends significantly on our success in many factors, including:

Even if one or more of the product candidates that we develop is approved for commercial sale, we anticipate incurring research, development, clinical trial, manufacturing and marketing costs associated with commercializing any approved products. Our expenses could increase beyond expectations if we are required by the FDA or other regulatory agencies, domestic or foreign, to change our manufacturing processes or assays, or to perform clinical, non-clinical,  or other types of studies in addition to those that we currently anticipate. If we are successful in obtaining regulatory approvals to market one or more of our product candidates, our revenue will be dependent, in part, upon the size of the markets in the territories for which we gain regulatory approval, the accepted price for the product, the ability to obtain reimbursement at any price, and whether we own the commercial rights for that territory. If the number of our addressable disease patients is not as significant as we estimate, the indication approved by regulatory authorities is narrower than we expect, or the reasonably expected population for treatment is narrowed by competition, physician choice or treatment guidelines, we may not generate significant revenue from sales of such products, even if approved. If we are not able to generate sufficient revenue from the sale of any approved products, we may never become profitable.

Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

We were incorporated and began our operations on April 30, 2015. Our operations to date have been limited to organizing and staffing our company, business planning, raising capital, conducting clinical trials of our lead product candidates, conducting pre-clinical studies of our other product candidates, and identifying additional potential product candidates. We have not yet demonstrated our ability to successfully complete any clinical trials, including large-scale, pivotal clinical trials, obtain marketing approvals, manufacture a commercial-scale drug or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful drug commercialization. Typically, it takes about six to 10 years to develop a new drug from the time it is in Phase 1 clinical trials to when it is approved for treating patients, but in many cases it may take longer. Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully developing and commercializing pharmaceutical products. In addition, as a business with a limited operating history, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors as we continue to develop and commercialize our product candidates. As we continue to build our business, we expect our financial condition and operating results to fluctuate significantly from quarter to quarter and year to year due to a variety of factors, many of which are beyond our control. Accordingly, you should not rely upon the results of any particular quarterly or annual periods as indications of future operating performance.

Our payment obligations to MSK may be a drain on our cash resources, or may cause us to incur debt obligations or issue additional equity securities to satisfy such payment obligations, which may adversely affect our financial position and results of operations.

Under the MSK License, we have committed to funding scientific research as well as conducting certain clinical trial activities at MSK through 2020. As licensed product candidates progress through clinical development and commercialization, certain milestone payments will come due, and we will owe MSK customary royalties on commercial sales of our approved products, if any, including, unless such royalties become due earlier, an annual fixed minimum royalty of $80,000 over the royalty term starting in 2020. These milestone payments become due upon achievement of the related clinical, regulatory or sales-based milestone set forth in the MSK License. Certain of the clinical and regulatory milestone payments become due at the earlier of completion of the related milestone activity or the date indicated in the MSK License, whether or not the milestone activity has been achieved. Total clinical and regulatory milestones potentially due under the MSK License are $2,450,000 and $9,000,000, respectively. There are also sales-based milestones that become due should we achieve certain amounts of sales of licensed products with total sales-based milestones potentially due of $20,000,000. Under the MSK CD33 License, we are obligated to make potential payments of $550,000, $500,000 and $7,500,000 for clinical, regulatory and sales-based milestones, respectively.

In addition, we have committed to acquire certain personnel and laboratory services at MSK under a Master Data Services Agreement, or MDSA, and two separate Core Facility Service Agreements, or CFSAs. We have also entered into an Investigator-Sponsored Master Clinical Trial Agreement, or MCTA, under which we will provide drug product and funding for certain clinical trials at MSK under separate appendices to be executed. Additionally, we entered into a Sponsored Research Agreement, or the SRA, with MSK pursuant to which we agreed to pay MSK to conduct certain research projects over a period of five years related to the intellectual property licensed under the MSK License. We also entered into a Sponsored Research Agreement, or the CD33 SRA, in connection with the MSK CD33 License, pursuant to which we committed to provide aggregate research funding to MSK annually for a term of two years. We entered into a Manufacturing Agreement with MSK’s Radiochemistry and Molecular Imaging Probes Core Facility, or RMIP, pursuant to which RMIP will complete specified manufacturing activities related to 131I-omburtamab in connection with our Phase 2 trials for Study 101. Additionally, we entered into a Sublicense Agreement, or the MabVax Sublicense, with MabVax Therapeutics Holdings, Inc., or MabVax, pursuant to which MabVax granted us all of the exclusive rights granted to MabVax under its license agreement with MSK, or the MabVax-MSK License, for a bi-valent ganglioside based vaccine intended to treat NB, or the NB vaccine. In addition to the upfront payment of $700,000 that we have made under the terms of MabVax Sublicense we have agreed to make an additional payment of $600,000 on the first anniversary of the MabVax Sublicense. We will also be responsible for any potential downstream payment obligations to MSK related to the NB vaccine that were specified in the MabVax-MSK License. This includes the obligation to pay development milestones totaling $1,400,000 and mid-single-digit royalty payments to MSK. These payments could be significant and in order to satisfy our obligations to MSK, if and when they are triggered, we may use our existing cash, incur debt obligations or issue additional equity securities, which may materially and adversely affect our financial position and results of operations.

On March 21, 2019, MabVax filed a voluntary petition for relief under Chapter 11 of Title 11 of the United States Bankruptcy Code (the “Bankruptcy Code”). MabVax has communicated that it continues to manage and operate its business as a debtor in possession pursuant to the Bankruptcy Code but that it intends to sell substantially all of its assets pursuant to Section 363 of the Bankruptcy Code in the sixty days following the filing of its Chapter 11 petition under a Bankruptcy Court supervised sales process. The consequences the voluntary petition for relief sought by MabVax are not yet known insofar as the MabVax Sublicense is concerned, but we believe that either the MabVax Sublicense continues on otherwise unchanged terms with an acquirer of the assets or that the terms of the MabVax Sublicense will continue to be honored by MSK.  

We will need substantial additional funding for our product candidates. If we fail to obtain additional funding for our product candidates, we may be forced to delay, reduce or eliminate our research and drug development programs or future commercialization efforts and our license and other agreements may be terminated.

Developing pharmaceutical products, including conducting pre-clinical studies and clinical trials, is a very time-consuming, expensive and uncertain process that takes years to complete. We expect our expenses to increase in connection with our ongoing activities, particularly as we conduct clinical trials of, and seek marketing approval for our lead product candidates and our other product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur commercialization expenses, which may be significant, related to product sales, marketing, manufacturing and distribution to the extent that such sales, marketing, manufacturing and distribution are not the responsibility of any collaborator that we may have at such time for any such product candidate. Furthermore, we expect to incur additional costs associated with operating as a public company. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise sufficient amounts of additional capital when needed or on attractive terms, we may be forced to delay, reduce or eliminate our research and drug development programs or our future commercialization efforts.

As of March 31, 2019, we had approximately $134.2 million in cash and cash equivalents. We believe that our cash and cash equivalents, will be sufficient to fund our operations and capital expenditures through the fourth quarter of 2020. However, changing circumstances may cause us to increase our spending significantly faster than we currently anticipate, and we may need to spend more money than currently expected because of circumstances beyond our control. We will require additional capital for further development and commercialization of our product candidates and may need to raise additional funds earlier if we choose to expand more rapidly than we presently anticipate.

In addition, we cannot be certain that additional funding will be available on acceptable terms, or at all. We have no firmly committed source of additional capital and if we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of our product candidates or other research and development initiatives. Our licenses and other agreements may also be terminated if we are unable to meet the payment obligations under the agreements. We could be required to seek collaborators for our product candidates at an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be available or relinquish or license on unfavorable terms our rights to our product candidates in markets where we otherwise would seek to pursue development or commercialization ourselves. Any of the above events could significantly harm our business, prospects, financial condition and results of operations and cause the price of our common stock to decline.

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our product candidates on terms unfavorable to us.

We expect our expenses to increase in connection with our planned operations. Until such time, if ever, as we can generate substantial revenues from the sale of our product candidates, we expect to finance our cash needs through a combination of cash on hand, equity offerings, debt financings, collaborations, strategic alliances and/or licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities could include liquidation or other preferences and anti-dilution protections that could adversely affect your rights as a common stockholder. In addition, debt financing, if available, would result in fixed payment obligations and may involve agreements that include restrictive covenants that limit our ability to take specific actions, such as incurring additional debt, making capital expenditures or acquisitions, limiting our ability to conduct licensing transactions, creating liens, redeeming stock or declaring dividends, that could adversely impact our ability to conduct our business. In addition, securing financing could require a substantial amount of time and attention from our management and may divert a disproportionate amount of their attention away from day-to-day activities, which may adversely affect our management’s ability to oversee the development of our product candidates.

If we raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights related to our intellectual property, future revenue streams or any of

our future product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds when needed, we may be required to delay, reduce and/or eliminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

If we engage in future acquisitions or strategic partnerships, this may increase our capital requirements, dilute our stockholders if we issue equity securities, cause us to incur debt or assume contingent liabilities, and subject us to other risks.

We may evaluate various acquisitions and strategic partnerships, including licensing or acquiring complementary products, intellectual property rights, technologies, or businesses. Any potential acquisition or strategic partnership may entail numerous risks, including:

In addition, if we undertake acquisitions, we may issue dilutive securities, assume or incur debt obligations, incur large one-time expenses and acquire intangible assets that could result in significant future amortization expense. Moreover, we may not be able to locate suitable acquisition opportunities, which could impair our ability to grow or obtain access to technology or products that may be important to the development of our business.

We may expand our resources to pursue a particular product candidate or indication and fail to capitalize on other product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

We intend to focus our efforts and managerial resources on specific product candidates and on specific indications. As a result, we may forgo or delay pursuit of opportunities with other product candidates or for other indications that may prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Failure to properly assess potential product candidates for indications could result in focusing on product candidates for indications with lower market potential, which could harm our business and financial condition. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable product candidates. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through partnering, licensing or other royalty arrangements

in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate or product.

It has been determined that we have material weaknesses in our internal control over financial reporting. If our remediation of these material weaknesses is not effective, or if we experience additional material weaknesses or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock. In addition, because of our status as an emerging growth company, our independent registered public accounting firm is not required to provide an attestation report as to our internal control over financial reporting for the foreseeable future.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with generally accepted accounting principles, or GAAP. As a public company, we are required, pursuant to Section 404 of the Sarbanes-Oxley Act, to furnish a report by our management on, among other things, the effectiveness of our internal control over financial reporting beginning with the annual report for our fiscal year 2019. This assessment will need to include disclosures of any material weaknesses identified by our management in our internal control over financial reporting. A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. We are in the very early stages of the costly and challenging process of planning the activities necessary to perform the evaluation needed to comply with Section 404.

In connection with the audit of our financial statements for the years ended December 31, 2017 and 2018, it was determined that we lack a sufficient number of trained professionals with an appropriate level of accounting knowledge, training and experience to: (a) design and maintain formal accounting policies, procedures and controls over the fair presentation of our financial statements; (b) analyze, record and disclose complex accounting matters timely and accurately, including share based compensation arrangements and accounting for license arrangements; and (c) design and maintain controls over the preparation and review of account reconciliations, journal entries and financial statements, including maintaining appropriate segregation of duties.

Each of these control deficiencies could result in a misstatement of these accounts or disclosures that would result in a material misstatement of our annual or interim consolidated financial statements that would not be prevented or detected, and accordingly, it was determined that these control deficiencies constitute material weaknesses.

We have hired finance professionals in 2018 with the plan to help mitigate the identified material weaknesses and are evaluating the implementation of additional procedures to address these material weaknesses.

We cannot assure you however that these or other measures will fully remediate the material weaknesses described above in a timely manner. We have commenced addressing the material weaknesses identified above by hiring additional finance and accounting personnel and increasing the oversight and review procedures with regard to financial reporting, financial processes and procedures and internal control procedures. Nevertheless, we cannot assure you that we will be able to remedy our current material weaknesses. If we are unable to remediate the material weaknesses, or otherwise maintain effective internal control over financial reporting, we may not be able to report our financial results accurately, prevent fraud or file our periodic reports in a timely manner. If our remediation of these material weaknesses is not effective, or if we experience additional material weaknesses or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock. We cannot assure you that all of our existing material weaknesses have been identified, or that we will not in the future identify additional material weaknesses.

Our independent registered public accounting firm will not be required to formally attest to the effectiveness of our internal control over financial reporting pursuant to Section 404 until the later of our fiscal year 2019, or the date we

are no longer an “emerging growth company” as defined in the JOBS Act, if we take advantage (as we expect to do) of the exemptions contained in the JOBS Act. We will remain an “emerging growth company” for up to five years, although if the market value of our common stock that is held by non-affiliates exceeds $700.0 million as of June 30 of any year before that time, we would cease to be an “emerging growth company” as of December 31 of that year. At such time, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our controls are documented, designed or operating. Our remediation efforts may not enable us to avoid material weaknesses in our internal control over financial reporting in the future.

If we are unsuccessful in building an appropriate accounting infrastructure, we may not be able to prepare and disclose, in a timely manner, our financial statements and other required disclosures, or comply with existing or new reporting requirements. Any failure to report our financial results on an accurate and timely basis could result in sanctions, lawsuits, delisting of our shares from the NASDAQ Global Select Market or other adverse consequences that would materially harm to our business. If we cannot provide reliable financial reports or prevent fraud, our business and results of operations could be harmed and investors could lose confidence in our reported financial information. Any of the foregoing occurrences, should they come to pass, could negatively impact the public perception of our company, which could have a negative impact on our stock price.

Risks Related to Product Development and Commercialization

Our product candidates and related technologies are novel approaches to cancer treatment that present significant challenges, and our ability to generate product revenue is dependent on the success of one or more of our lead product candidates, which will require additional clinical testing before we can seek regulatory approval and begin commercial sales.

Our product candidates and related technologies represent novel approaches to cancer treatment generally, and developing and commercializing our product candidates subjects us to a number of challenges. We currently generate no revenues from sales of any products, we have never obtained marketing approval for a product candidate and we may never be able to develop a marketable product. Our ability to generate product revenue is highly dependent on our ability to obtain regulatory approval of and successfully commercialize one or more of our lead product candidates, which will require additional clinical and non-clinical development, regulatory review and approval in each jurisdiction in which we intend to market them, substantial investment, access to sufficient commercial manufacturing capacity, and significant marketing efforts before we can generate any revenue from product sales. We cannot be certain that any of our product candidates will be successful in clinical studies and they may not receive regulatory approval even if they are successful in clinical studies.

The success of our product candidates, including our lead product candidates, will depend on several factors, including the following:
