NEW YORK, Nov. 08, 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 third quarter ended September 30, 2024.

“The third quarter of this year was one of continued focus and execution across our DANYELZA commercial business and our novel SADA PRIT radiopharmaceutical platform development pipeline,” said Michael Rossi, President and Chief Executive Officer. “Physician usage of DANYELZA in the U.S. continues to remain very strong for patients with relapsed/refractory high-risk neuroblastoma. In addition, we continue to drive ex-U.S. market expansion with our new exclusive license and distribution agreement with Nobelpharma in Japan and the launch of our named patient program in Turkey. From a SADA PRIT pipeline standpoint, we expect to complete Part A of our GD2-SADA Phase 1 trial this year and present that data in the first quarter of next year.”

Financial Results

Revenues

Total net revenues for the quarter ended September 30, 2024 were $18.5 million, a 10% decline over total net revenues for the quarter ended September 30, 2023 of $20.5 million, which included $0.5 million in license revenue, primarily driven by decreased net product revenues in both U.S. and ex-U.S. markets.

Total net revenues for the nine months ended September 30, 2024 were relatively flat compared to the nine months ended September 30, 2023, at $61.2 million and $61.5 million, respectively. The slight decrease was driven by a $0.7 million decrease in ex-U.S. DANYELZA net product revenues in the nine months ended September 30, 2024, which was partially offset by increased net product revenues in the U.S.

The Company’s U.S. DANYELZA net product revenues were $15.3 million and $16.1 million for the three months ended September 30, 2024 and 2023, respectively, representing a 5% decline, primarily due to an unfavorable price mix, partially offset by increased volume of 5% vial growth over the same time period.

Y-mAbs’ ex-U.S. DANYELZA net product revenues for the quarter ended September 30, 2024 were $3.1 million, a 19% decline from $3.9 million in the comparable period in 2023, primarily driven by decreased volume from Western Europe partially offset by volume increases in the remaining ex-U.S. territories.

As of September 30, 2024, Y-mAbs had delivered DANYELZA to 68 centers across the U.S. since initial launch, with three new accounts added in the U.S. in the third quarter of 2024. During the quarter ended September 30, 2024, approximately 65% of the vials sold in the U.S. were sold outside of Memorial Sloan Kettering Cancer Center (“MSK”), compared to 67% in the second quarter ended June 30, 2024.

The Company did not have license revenue for the quarter ended September 30, 2024. The Company had license revenues of $0.5 million for the nine months ended September 30, 2024, from its Latin America distribution partner, Adium, related to price approval for DANYELZA in Brazil from the Brazilian Medicines Market Regulation Chamber. The Company had license revenues of $0.5 million for the quarter and nine months ended September 30, 2023 from Adium, recognized upon the September 2023 achievement of marketing authorization for DANYELZA in Mexico.

Operating Costs and Expenses

Cost of Goods Sold

Cost of goods sold were $2.3 million and $2.6 million for the quarter ended September 30, 2024 and 2023, respectively. Cost of goods sold were $7.4 million and $9.3 million for the nine months ended September 30, 2024 and 2023, respectively. Cost of goods sold included lower vial volumes of 1% and 37% in the three and nine months ended September 30, 2024, compared to the same periods in 2023, respectively. Cost of goods sold also included $0.4 million and $0.8 million inventory write-downs in the three and nine months ended September 30, 2023, respectively.

The Company defines gross margin as net product revenues less cost of goods sold divided by net product revenues. The Company’s gross margins was relatively unchanged in the quarter ended September 30, 2024, compared to the comparable periods in 2023. The Company’s gross margins increased in the nine months ended September 30, 2024, compared to the comparable period in 2023, due to a favorable gross profit mix from revenue in international regions, particularly Eastern Asia that had an inventory stocking order in the nine months ended September 30, 2024, and inventory write-downs during the comparable periods in 2023, as noted above.

Research and Development

Research and development expenses were $11.2 million for the quarter ended September 30, 2024, a decrease of $4.2 million when compared with the same period in 2023. The decrease in research and development expenses was primarily attributable to the recognition of $4.1 million of milestone and license acquisition costs related to the Company’s SADA license agreement during the three months ended September 30, 2023, as certain time-based clinical milestones within the agreement were determined to be probable based on the availability of necessary data and the assessment of clinical progress in the third quarter of 2023.

For the nine months ended September 30, 2024, research and development expenses were $36.8 million, a decrease of $4.0 million when compared with the same period in 2023. The decrease in the research and development expenses was primarily attributable to recognition of $4.1 million of milestone and license acquisition costs related to the Company’s SADA license agreement during the nine months ended September 30, 2023, as noted above.

Selling, General, and Administrative

Selling, general, and administrative expenses were $13.6 million and $10.2 million for the quarters ended September 30, 2024 and 2023, respectively. The $3.4 million increase in the selling, general and administrative expenses was primarily attributable to a $1.2 million increase related to the Company’s former Chief Financial Officer’s separation and consulting agreements, $1.1 million increase in personnel cost, inclusive of stock-based compensation and $0.5 million in professional and consulting fees.

For the nine months ended September 30, 2024, selling, general, and administrative expenses were $42.3 million, an increase of $8.5 million compared with the same period in 2023. The increase was primarily attributable to a net impact of $3.6 million related to the settlement of a shareholder class-action lawsuit in the nine months ended September 30, 2024, and an additional legal settlement of $0.2 million in the nine months ended September 30, 2024. The increase also includes a $1.2 million increase related to our former Chief Financial Officer’s separation and consulting agreements, a $1.1 million increase in personnel cost inclusive of stock-based compensation and $0.8 million in professional and consulting fees.

Interest and Other Income

Interest and other income were $1.9 million for the quarter ended September 30, 2024, as compared to $0.2 million for the quarter ended September 30, 2023. The increase of $1.7 million was primarily due to a $1.9 million of foreign currency transactional gains in the three months ended September 30, 2024, partially offset by a $0.2 million decrease in interest earned on the Company’s cash and cash equivalents.

For the nine months ended September 30, 2024 and 2023, the interest and other income was $3.0 and $2.4 million, respectively. The increase of $0.6 million was primarily due to $1.1 million of foreign currency transactional gains, partially offset by a $0.3 million decrease in interest earned on the Company’s cash and cash equivalents.

Net Loss

Y-mAbs reported a net loss for the quarter ended September 30, 2024, of $7.0 million, or ($0.16) per basic and diluted share, compared to a net loss of $7.7 million, or ($0.18) per basic and diluted share, for the quarter ended September 30, 2023. The decrease in net loss for the quarter ended September 30, 2024 was primarily driven by decreased operating expenses and foreign currency transactional gains, partially offset by decreased net product revenue.

For the nine months ended September 30, 2024, the Company reported a net loss of $22.9 million, or ($0.52) per basic and diluted share, as compared to net loss of $20.4 million, or ($0.47) per basic and diluted share, for the nine months ended September 30, 2023. The increase in net loss for the nine months ended September 30, 2024 was primarily driven by the net $3.8 million in charges related to the Company’s two legal settlements, as described above.

Cash and Cash Equivalents

As of September 30, 2024, Y-mAbs had approximately $68.1 million in cash and cash equivalents. Cash utilized in the first three quarters of 2024 was $10.5 million, which was favorable relative to the Company’s internal forecasts, and is on track to meet its corporate guidance for the full year 2024.
