NEW YORK, May 07, 2024 (GLOBE NEWSWIRE) -- Y-mAbs Therapeutics, Inc. (the “Company” or “Y-mAbs”) (Nasdaq: YMAB), a commercial-stage biopharmaceutical company focused on the development and commercialization of novel radioimmunotherapy and antibody-based therapeutic products for the treatment of cancer, today reported financial results for the first quarter ended March 31, 2024.

“We continued to make meaningful progress across our commercial and clinical development initiatives during the first quarter of this year,” said Mike Rossi, President and Chief Executive Officer. “On the commercial front, the first quarter of 2024 marked the highest quarter of U.S. demand for DANYELZA® (naxitamab-gqgk) since its initial launch. Our recorded net product revenues in the first quarter were primarily driven by heightened demand across both new and existing U.S. accounts. DANYELZA remains a leading anti-GD2 therapy, and we continue to believe in its potential to serve patients beyond the high-risk relapse/refractory neuroblastoma market. In addition, we are highly encouraged by the clinical advancement of our Self-Assembly DisAssembly (“SADA”) Pretargeted Radioimmunotherapy (“PRIT”) Technology platform. With the potential to deliver optimal therapy with minimal toxicity, increase physician participation in the patient treatment journey, and leverage existing infrastructure as a potentially isotope-agnostic platform, we believe SADA PRIT has the potential to make a positive and lasting impact on patient care.”

Financial Results

Revenues

DANYELZA total net product revenues were $19.4 million for the quarter ended March 31, 2024, which represented a decrease of 4% over $20.3 million in the comparable period of 2023. Y-mAbs’ U.S. DANYELZA net product revenues were $18.6 million for the quarter ended March 31, 2024, an increase of 11% over $16.8 million in the comparable period of 2023. The Company had international DANYELZA net product revenues of $0.8 million and $3.4 million in the quarters ended March 31, 2024 and 2023, respectively. The decrease in the quarter ended March 31, 2024, compared to the quarter ended March 31, 2023, was a result of a 2023 initial product stocking shipment of $2.5 million to Y-mAbs’ distribution partner, WEP, in connection with an early access program for DANYELZA in Europe. The Company did not have a shipment to WEP in the quarter ended March 31, 2024. Volumes for international shipments can vary from quarter to quarter, and the Company expects a higher volume to resume in future quarters in 2024.

U.S. DANYELZA net product revenues increased 3% compared to the quarter ended December 31, 2023, when excluding the $0.3 million and $1.3 million impact of a Medicaid accrual change in estimate recognized as increases in net product revenues in the quarters ended March 31, 2024 and December 31, 2023, respectively. DANYELZA total net product revenues of $19.4 million in the first quarter of 2024, represented a 17% decrease compared to the fourth quarter of 2023, primarily driven by decreased international revenues.

As of March 31, 2024, Y-mAbs has delivered DANYELZA to 63 centers across the U.S. since initial launch, with five new accounts added in the first quarter of 2024. During the quarter ended March 31, 2024, approximately 60% of the vials sold in the U.S. were sold outside of Memorial Sloan Kettering Cancer Center (“MSK”), compared to 55% in the fourth quarter ended December 31, 2023.

The Company had license revenues of $0.5 million for the quarter ended March 31, 2024. License revenue for the quarter ended March 31, 2024 arose from the January 2024 acceptance of the Brazilian Medicines Market Regulation Chamber (“CMED”) price for DANYELZA. The Company did not have license revenue for the quarter ended March 31, 2023.

Operating Costs and Expenses

Cost of Goods Sold

Cost of goods sold was $2.1 million for the quarters ended March 31, 2024 and 2023, respectively.

The Company’s gross margin in the quarters ended March 31, 2024 and 2023 remained approximately constant at 89% and 90%, respectively. The Company defines gross margin as net product revenues less cost of goods sold divided by net product revenues.

Research and Development

Research and development expenses were $13.3 million for the quarter ended March 31, 2024, a decrease of 1% compared to $13.4 million for the quarter ended March 31, 2023. The $0.1 million decrease was mainly due to decreased personnel related costs of $2.6 million, inclusive of the impact of the Company’s restructuring charge recorded in the quarter ended March 31, 2023, partially offset by a $2.5 million increase in clinical trial expenses related to the Company’s investments in SADA PRIT Technology in 2024.

Selling, General, and Administration

Selling, general, and administrative expenses were $11.4 million for the quarter ended March 31, 2024, which was a $0.8 million decrease compared to $12.2 million for the quarter ended March 31, 2023. The $0.8 million decrease in selling, general, and administrative expenses was primarily attributable to a decrease in personnel related costs related to the Company’s $1.1 million restructuring charge recorded in the quarter ended March 31, 2023.

Interest and Other Income

Interest and other income was $0.4 million for the quarter ended March 31, 2024, as compared to $1.1 million for the quarter ended March 31, 2023. The decrease of $0.7 million was primarily due to a $0.6 million decrease in foreign currency transaction income.

Net Loss

Y-mAbs reported a net loss for the quarter ended March 31, 2024, of $(6.6) million, or $(0.15) per basic and diluted share, which was relatively flat compared to net loss of $(6.4) million, or $(0.15) per basic and diluted share, for the quarter ended March 31, 2023.

Cash and Cash Equivalents

As of March 31, 2024, Y-mAbs had approximately $75.7 million in cash and cash equivalents which, together with anticipated DANYELZA product revenues, is expected to support operations as currently planned into 2027. This estimate reflects the Company’s current business plan that is supported by assumptions that may prove to be inaccurate, such that Y-mAbs could use its available capital resources sooner than it currently expects. The cash burn for the first quarter of 2024 was $2.9 million.

2024 Financial Guidance

Management reiterates its full year 2024 guidance:

• Anticipated total DANYELZA® net product revenues of between $95 million and $100 million;
• Anticipated operating expenses of between $115 million and $120 million;
• Anticipated total annual cash burn of between $15 million and $20 million; and
• Cash and cash equivalents anticipated to continue to support operations as currently planned into 2027.
