Y-mAbs Announces 2018 Financial Results and Corporate Development Highlights


New York, NY, March 22, 2019 (GLOBE NEWSWIRE) — Y-mAbs Therapeutics, Inc. (the “Company” or “Y-mAbs”) (Nasdaq:YMAB) a late-stage clinical biopharmaceutical company focused on the development and commercialization of novel, antibody-based therapeutic products for the treatment of cancer, today reported financial results for 2018.


“We are very pleased to report our first full year financials after Y-mAbs’ successful IPO in September, which we believe has put us in a strong financial position to continue the important work on our two lead pediatric compounds, naxitamab and omburtamab. We plan to file BLAs for both of these compounds by the end of 2019.” stated Thomas Gad, Founder, President and Head of Business Development and Strategy.


Dr. Moller, Chief Executive Officer continued, “We believe we have made solid clinical progress with naxitamab and omburtamab during 2018. In 2019, we have much to do and also many catalysts that have the potential to solidify us as a leader in pediatric oncology and as a company focused on rapidly developing therapies to extend and enhance the lives of those living with rare pediatrics cancers.”


Financial Year 2018 and Corporate Development Highlights


·                  On December 13, 2018, Y-mAbs announced the appointment of Dr. Gérard Ber, PhD to its board of directors, and the planned departure of Dr. Michael Buschle, PhD. Dr. Ber most recently served as Chief Operating Officer of Advanced Accelerator Applications SA, which he co-founded in 2002. Dr. Ber brings over 30 years of experience in molecular nuclear medicines, including development, production and commercialization of diagnostics and therapeutic products for several indications in oncology, cardiology, neurology and infectious/inflammatory diseases.


·                  On December 10, 2018, Y-mAbs announced FDA clearance of the IND for the Company’s humanized bispecific GD2 antibody. The IND was submitted by Memorial Sloan Kettering Cancer Center, who has licensed the antibody to Y-mAbs. A Phase 1/2 clinical trial has been initiated for patients with relapsed/refractory neuroblastoma, high grade osteosarcoma and other GD2(+) solid tumors, where patients have relapsed or refractory disease that is resistant to standard therapy. Y-mAbs expects that this bispecific GD2 antibody may have potential advantages over other bispecific antibodies, such as improved potency due to bivalency, binding to neonatal Fc receptor and longer serum half-life, which obviates continuous infusion and enables more convenient administration to the patient.


·                  On November 1, 2018, Y-mAbs announced that that Dr. Jeong A Park from the Department of Pediatrics of Memorial Sloan-Kettering Cancer Center would present preclinical data from the Company’s bispecific GD2 antibody at the American Society of Hematology (ASH) Annual Meeting. Bispecific GD2 antibodies were tested in solid tumors in preclinical models with T-cells and were shown to exert anti-tumor effect against GD2(+) tumor xenografts or PDX tumors. Further, the bispecific GD2 antibodies induced rapid and quantitative T-cell homing to tumors, mediating antibody dependent T-cell mediated cytotoxicity (ADTC) against GD2, and were shown to infiltrate tumors with little to no immune response, also known as cold tumors.


·                  On October 23, 2018, Y-mAbs announced that the Committee for Orphan Medicinal Products of the European Medicines Agency recommended the granting of orphan medicinal product designation in the European Union for naxitamab for the treatment of relapsed or refractory high-risk neuroblastoma. Further, the positive opinion for orphan medicinal product designation had been sent to the European Commission, which subsequently granted the orphan drug designation.



·                  On September 25, 2018, Y-mAbs announced the closing of its initial public offering of 6,900,000 shares of its common stock, including the exercise in full of the underwriters’ option to purchase 900,000 additional shares of common stock, at a public offering price of $16.00 per share.  The gross proceeds to Y-mAbs, before deducting underwriting discounts and commissions and estimated offering expenses payable by the Company, were approximately $110.4 million.  All of the shares of common stock were offered by the Company, and Y-mAbs’ common stock is listed on The Nasdaq Global Select Market.


·                  On August 21, 2018, Y-mAbs announced that it had received Breakthrough Therapy designation for naxitamab, in combination with GM-CSF, for the treatment of high risk neuroblastoma refractory to initial therapy or with incomplete response to salvage therapy in patients older than 12 months of age with persistent, refractory disease limited to bone marrow with or without evidence of concurrent bone involvement.


·                  On July 10, 2018, Y-mAbs announced that it had entered into an exclusive sublicense with MabVax Therapeutics for its patented neuroblastoma vaccine, which is a bi-valent ganglioside based vaccine intended to treat neuroblastoma. The neuroblastoma vaccine was originally developed by Memorial Sloan Kettering Cancer Center and licensed to MabVax as part of a portfolio of anti-cancer vaccines. MabVax was granted Orphan Drug Designation for the vaccine. Under the terms of the sublicense, the Company has agreed to pay MabVax up to $1.3 million, consisting of an upfront payment of $700,000, and an additional payment of $600,000 on the first anniversary of the sublicense.


·                  On April 16, 2018, Y-mAbs announced positive Phase I data from treatment with omburtamab in Desmoplastic Small Round Cell Tumor (DSRCT), which is a rare sarcoma of adolescents and young adults. The phase I study of radioiodinated omburtamab was conducted at Memorial Sloan Kettering Cancer Center evaluate toxicity, pharmacokinetics, biodistribution and efficacy. A total of 41 DSRCT patients were treated with escalated doses of intraperitoneal omburtamab as radioimmunotherapy, and the compound had a satisfactory safety profile and appeared to have activity against micro-metastatic DSRCT.


Financial Results


Y-mAbs reported a net loss of $43.3 million, or $1.50 per basic and diluted share, for the financial year 2018 compared to a net loss of $19.2 million, or $0.99 per basic and diluted share for 2017.


Cost and Operating Expenses


Research and development


Research and development expenses were $34.3 million for the year ended December 31, 2018, compared to $14.3 million for 2017, an increase of $20.0 million. The increase in research and development expenses primarily reflects the following:


·                  $7.5 million increase in outsourced manufacturing for our lead product candidates, naxitamab and omburtamab

·                  $4.6 million increase in outsourced research and supplies to support expanding development activities

·                  $2.8 million increase in clinical trial costs due to an increasing number of ongoing clinical trials

·                  $3.2 million increase in personnel costs

·                  $0.6 million increase in milestone payments



General and administration


General and administrative expenses were $9.0 million for the year ended December 31, 2018, compared to $4.9 million for the same period of 2017, an increase of $4.1 million. The increase in general and administrative expenses primarily reflects the following:


·                  $1.8 million increase in personnel costs

·                  $0.7 million increase in fees for auditors, legal advice and other consultancy services

·                  $0.4 million increase in leasehold expenses


Cash and Cash Equivalents


The Company had approximately $147.8 million in cash and cash equivalents as of December 31, 2018 compared to $90.5 million as of December 31, 2017. The increase is primarily driven by the $99.8 million net proceeds from the Company’s initial public offering, which is partly offset by the use of cash to fund the Company’s ongoing operations during 2018.
