NEW YORK, March 04, 2025 (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 fourth quarter and full year ended December 31, 2024.

“We delivered on the strategic priorities we set out to achieve in 2024 across our business,” said Michael Rossi, President and Chief Executive Officer. “In our DANYELZA business, we saw solid ex-U.S. growth in 2024 from our partners. In the U.S., while DANYELZA revenues stabilized in the face of increased competition from new market entrants and clinical trial activity, we remain committed to further penetrating high-volume centers and reaching more patients with high-risk relapsed/refractory neuroblastoma. In our Radiopharmaceutical business, we demonstrated the tolerability and validity of our SADA PRIT platform pre-targeting approach with the preliminary readout from Part A of our GD2-SADA Phase 1 trial, Trial 1001, in solid tumors, and we look forward to providing a complete data readout in the second quarter of this year. With our business realignment announced at the beginning of 2025, we expect to be in position to enhance our ability to execute on our business goals to drive future growth with DANYELZA while accelerating the preclinical and clinical advancement of our SADA PRIT platform and programs.”

Recent Corporate Highlights

• On January 10, 2025, Y-mAbs announced the internal realignment and establishment of two business units: DANYELZA and Radiopharmaceuticals. The business realignment is designed to support the optimization of internal resources and provide flexibility and agility to advance the Company’s novel Self-Assembly DisAssembly Pre-targeted Technology platform (SADA PRIT) programs through clinical development while simultaneously driving commercial growth of DANYELZA.
• In conjunction with the business realignment, Y-mAbs appointed Doug Gentilcore as Senior Vice President, Head of DANYELZA Business Unit. Mr. Gentilcore has over two decades of strategic leadership experience in the pharmaceutical industry.
• Y-mAbs presented translational pharmacokinetics data of GD2-SADA at the Society of Nuclear Medicine & Molecular Imaging (SNMMI) Mid-Winter and American College of Nuclear Medicine (ACNM) Annual Meeting on January 31, 2025. The poster titled “Preclinical and Translational Pharmacokinetics of GD2-SADA, a Self-Assembling and Disassembling (SADA) Bispecific Fusion Protein for Pre-targeted Radioimmunotherapy (PRIT)” characterizes the plasma levels of GD2-SADA in animal models over time and a range of doses, while also presenting the concentration- and time-dependent equilibrium between GD2-SADA tetramers and monomers in vitro. Incorporated within translational PK simulations, the data have provided insights into GD2-SADA tumor exposure and plasma elimination, key parameters for minimizing systemic exposure to ¹⁷⁷Lutetium-DOTA.
• Interim data from a Phase 2 clinical trial evaluating naxitamab with granulocyte-macrophage colony-stimulating factor (GM-CSF) in patients with relapsed/refractory high-risk neuroblastoma in the journal Nature Communications. The article, titled “The anti-GD2 monoclonal antibody naxitamab plus GM-CSF for relapsed or refractory high-risk neuroblastoma: a phase 2 clinical trial,” details the results of a single-arm, global Phase 2 trial (Trial 201, NCT03363373) of patients with relapsed/refractory high-risk neuroblastoma and residual disease in the bone/bone marrow who received naxitamab on days 1, 3, and 5 (3 mg/kg/day) with GM-CSF (days -4 to 5) every 4 weeks, until a complete response (CR) or partial response (PR) was achieved, followed by 5 additional cycles every 4 weeks. Overall, naxitamab demonstrated statistically significant efficacy with a manageable safety profile.

Fourth Quarter 2024 Key Highlights

• Y-mAbs entered into an exclusive license and distribution agreement with Nobelpharma Co. Ltd. for the development and commercialization of DANYELZA in Japan. Y-mAbs received an upfront payment of $2.0 million in the fourth quarter of 2024.

Financial Results

Revenues

Total revenues for the quarter ended December 31, 2024 were $26.5 million, which was a 13% increase over the $23.4 million of total revenues for the quarter ended December 31, 2023, primarily driven by a $2.0 million increase in license revenue, and a $1.1 million increase in net product revenues.

Total revenues for the year ended December 31, 2024 were $87.7 million, a 3% increase over the total revenues for the year ended December 31, 2023 of $84.8 million. The $2.9 million increase was driven by a $2.0 million increase in license revenue, and a $0.9 million increase in net product revenues.

The Company’s U.S. DANYELZA net product revenues for the quarter and year ended December 31, 2024 were $16.8 and $66.0 million, representing decreases of 12% and 3%, respectively, from the same periods in 2023. The decline in the U.S. DANYELZA net product revenues was driven by an unfavorable price mix for the quarter and year ended December 31, 2024, compared to 2023. The decline for the quarter ended December 31, 2024, was partially offset by slightly increased volume, compared to 2023.

The Company’s international DANYELZA net product revenues for the quarter and year ended December 31, 2024 were $7.7 million and $19.2 million, representing increases of 78% and 16%, respectively, from the same periods in 2023. The increase in the international DANYELZA net product revenues was driven by the named patient program launch in Western Asia in 2024 and increased net product sales in the Eastern Asia, where our distribution partner purchased inventory in 2024 to avoid potential supply disruption in advance of a planned post-marketing labeling change in 2025, and Latin America regions, partially offset by decreased sales in Western Europe.

As of December 31, 2024, Y-mAbs had delivered DANYELZA to 69 centers across the U.S. since initial launch, with 11 new accounts added in the U.S. in 2024. During the quarter ended December 31, 2024, approximately 64% of the vials sold in the U.S. were sold outside of Memorial Sloan Kettering Cancer Center (“MSK”), compared to 65% in the third quarter ended September 30, 2024.

During the quarter and year ended December 31, 2024, the Company recognized license revenue of $2.0 million upon the execution of a license agreement with Nobelpharma in October 2024. The Company had license revenues totaling $2.5 million for the year ended December 31, 2024, which included license revenue from the Latin America distribution partner, Adium, related to price approval for DANYELZA in Brazil from the Brazilian Medicines Market Regulation Chamber, and from Nobelpharma, as noted above. The Company did not have any license revenue for the quarter ended December 31, 2023. The Company had license revenues of $0.5 million for the year ended December 31, 2023 from Adium, recognized upon the September 2023 achievement of marketing authorization for DANYELZA in Mexico.

Cost of Goods Sold

Cost of goods sold were $7.6 million and $2.0 million for the quarters ended December 31, 2024 and 2023, respectively, and were $15.0 million and $11.4 million for the years ended December 31, 2024 and 2023, respectively. Cost of goods sold included $0.6 million inventory write-off for the quarter and year ended December 31, 2024. The Company did not have any inventory write-off for the quarter ended December 31, 2023, and the Company had $0.8 million inventory write-downs in the year ended December 31, 2023.

Gross Profit

Gross profit was $18.9 million and $21.3 million for the quarters ended December 31, 2024 and 2023, respectively. Gross profit was $72.7 million and $73.5 million for the years ended December 31, 2024 and 2023, respectively. The decrease in gross profit was driven by the unfavorable price mix in connection with increased net product revenue from Eastern Asia, which generally has lower gross margins.

Operating Costs and Expenses

Research and Development

Research and development expenses were $12.2 million and $13.4 million for the quarters ended December 31, 2024 and 2023, respectively. The decrease in research and development expenses was primarily due to a $1.8 million decrease in outsourced manufacturing, a $0.4 million reduction of future milestone payments as the Company entered into an amendment with MSK to return the licensed patent rights related to omburtamab, and related drug substance inventory and regulatory work products, partially offset by a $1.0 million expense related to severance benefits and stock-based compensation charges associated with our business realignment.

Research and development expenses were $49.0 million for the year ended December 31, 2024, a decrease of $5.2 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 year ended December 31, 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.

Selling, General, and Administrative

Selling, general, and administrative expenses were $12.4 million and $11.1 million for the quarters ended December 31, 2024 and 2023, respectively. The $1.3 million increase in the selling, general and administrative expenses was primarily attributable to a $0.8 million increase in personnel cost, inclusive of stock-based compensation, and a $0.6 million expense related to severance benefits and stock-based compensation charges associated with our business realignment.

For the year ended December 31, 2024, selling, general, and administrative expenses were $54.6 million, an increase of $9.7 million compared with the same period in 2023. The increase was primarily attributable to a net impact of $3.8 million related to legal settlements, a $1.2 million charge related to separation and consulting agreements with a former executive and a $2.2 million increase in personnel cost, inclusive of stock-based compensation.

Interest and Other (Loss)/Income

The Company experienced interest and other loss of $1.6 million for the quarter ended December 31, 2024, as compared to interest and other income of $2.4 million for the quarter ended December 31, 2023. The decrease of $4.0 million was primarily due to a $3.7 million decrease in foreign currency transactional gains in the three months ended December 31, 2024, and a $0.3 million decrease in interest earned on the Company’s cash and cash equivalents.

For the years ended December 31, 2024 and 2023, the interest and other income was $1.4 and $4.8 million, respectively. The decrease of $3.4 million was primarily due to $2.6 million decrease of foreign currency transactional gains, partially offset by a $0.7 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 December 31, 2024, of $6.8 million, or ($0.15) per basic and diluted share, compared to a net loss of $1.0 million, or ($0.02) per basic and diluted share, for the quarter ended December 31, 2023. For the year ended December 31, 2024, the Company reported a net loss of $29.7 million, or ($0.67) per basic and diluted share, as compared to net loss of $21.4 million, or ($0.49) per basic and diluted share, for the year ended December 31, 2023. The increase in net loss for the quarter and year ended December 31, 2024 was primarily driven by increased operating expenses and decreased foreign currency transactional gains, partially offset by increased total revenues.

Cash and Cash Equivalents

As of December 31, 2024, Y-mAbs had approximately $67.2 million in cash and cash equivalents. Total annual cash investment in 2024 was $11.4 million, which was favorable relative to the Company’s corporate guidance for the full year 2024, which was between $15 million and $20 million.
