Y-mAbs Announces Second Quarter 2019 Financial Results and Recent Corporate Developments

New York, NY, August 14, 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 the second quarter of 2019.

“We are very pleased with our second quarter results, highlighted by prudent spending combined with notable progress in the preparation of the initial portions of our rolling BLAs for our two lead product candidates, naxitamab and omburtamab, for submission to the FDA later this year.  We continue to solidify our position 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 pediatric cancers,” stated Thomas Gad, Founder, Chairman, President and Head of Business Development and Strategy.

Dr. Claus Moller, Chief Executive Officer, continued, “We believe our recent pre-BLA meeting with the FDA supports our ambition of initiating submission of a rolling BLA for naxitamab for the treatment of relapsed/refractory high-risk neuroblastoma in the fourth quarter of 2019, with the expectation that the final portion will be submitted in early 2020. We are also excited to initiate the submission of a rolling BLA for omburtamab for the treatment of central nervous system/leptomeningeal metastasis from neuroblastoma by the end of 2019, and expect to submit the two rolling BLAs almost concurrently. These are exciting times for Y-mAbs.”

Second Quarter 2019 and Recent Corporate Developments

·                 Subsequent to the end of the second quarter, on July 8, 2019, Y-mAbs announced that it has completed a successful pre-BLA meeting with the FDA regarding a potential pathway for FDA approval of naxitamab for the treatment of relapsed/refractory high-risk neuroblastoma. During the meeting, the Company reached alignment with the FDA on an Accelerated Approval Pathway for naxitamab along with a rolling BLA submission. The Company expects to submit the Clinical/Safety portion and the non-Clinical portion of the BLA in November 2019. For the Chemistry, Manufacturing and Controls (CMC) portion, the Company believes it will have sufficient data from the Process Performance Qualification (PPQ) batches to complete the CMC portion in early 2020. Y-mAbs continues to evaluate potential avenues to accelerate the submission of the CMC portion, and hopes to comply with FDA requirements at an earlier time.

·                  Also subsequent to the end of the second quarter, on July 1, 2019, Y-mAbs announced the status of patient recruitment for the Company’s two pivotal phase II trials, one for omburtamab for the treatment of central nervous system/leptomeningeal metastasis (CNS/LM) from neuroblastoma and the other for naxitamab for the treatment of relapsed/refractory high-risk neuroblastoma. As of June 30, 2019, all of the 18 planned omburtamab patients had been enrolled in the study. The Company believes it remains on track to start submission of a rolling BLA in 2019 under the Breakthrough Therapy Designation that the Company previously received from the FDA. For naxitamab, more than 30 patients of a planned total of 37 patients in the Company’s Study 201 had been enrolled in the study as of June 30, 2019.

·                  After the close of the second quarter, on July 1, 2019, Y-mAbs announced that the Company has entered into a development, manufacturing and supply agreement with SpectronRx in South Bend, Indiana, to secure access to clinical and commercial scale radiolabeling capacity for omburtamab. Under the terms of the agreement, SpectronRx has agreed to establish a manufacturing unit designated for Y-mAbs within its existing facilities, at which Y-mAbs believes both clinical and commercial supply of radiolabeled omburtamab can be produced.

·                  On June 26, 2019, Y-mAbs announced the acceptance of two oral presentations and five poster presentations at the International Society of Pediatric Oncology (SIOP) Annual Congress for its two lead product candidates, naxitamab and omburtamab.

·                  On May 15, 2019, Y-mAbs announced the acceptance of three poster presentations at the American Society of Clinical Oncology (ASCO) Annual Meeting for its two lead product candidates, naxitamab and omburtamab.

·                  On May 14, 2019, Y-mAbs announced an update on its GD2-GD3 Vaccine program for relapsed high-risk neuroblastoma. A total of 230 patients have received the GD2-GD3 Vaccine to date and Y-mAbs plans to begin using a newly manufactured Current Good Manufacturing Practice (cGMP) drug product in the fourth quarter of 2019.

Second Quarter 2019 Financial Results

Y-mAbs reported a net loss of $18.0 million, or $0.53 per basic and diluted share, for the three months ended June 30, 2019, compared to a net loss of $10.3 million, or $0.39 per basic and diluted share, for the three months ended June 30, 2018.

·                  $2.2 million increase in outsourced research and supplies to support expanding development activities; and

·                  $0.7 million increase in personnel costs.

Research and development expenses were $27.0 million for the six months ended June 30, 2019, compared to $14.5 million for the six months ended June 30, 2018, an increase of $12.5 million. The increase in research and development expenses primarily reflects the following:

·                  $7.2 million increase in outsourced manufacturing for our two lead product candidates, naxitamab and omburtamab;

·                  $3.5 million increase in outsourced research and supplies to support expanding development activities; and

·                  $1.4 million increase in personnel costs.

General and Administration

General and administrative expenses were $4.1 million for the three months ended June 30, 2019, compared to $2.0 million for the three months ended June 30, 2018, an increase of $2.1 million. Such increase in general and administrative expenses primarily reflects the following:

·                  $1.4 million increase in personnel costs; and

·                  $0.5 million increase in commercial infrastructure.

General and administrative expenses were $7.9 million for the six months ended June 30, 2019, compared to $3.2 million for the six months ended June 30, 2018, an increase of $4.7 million. Such increase in general and administrative expenses primarily reflects the following:

·                  $2.8 million increase in personnel costs; and

·                  $0.8 million increase in commercial infrastructure costs.

Cash and Cash Equivalents

The Company had approximately $120.2 million in cash and cash equivalents as of June 30, 2019, compared to $147.8 million as of December 31, 2018. The decrease of $27.6 million was primarily attributable to the increased costs of operation as the Company prepares for its submission of rolling BLAs for naxitamab and omburtamab and the build-up of the Company’s commercial infrastructure.
