PRINCETON, N.J., May 13, 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 first quarter ended March 31, 2025.

“We closed the first quarter of 2025 demonstrating solid DANYELZA net product revenue, advancement of our novel SADA PRIT platform and programs, and prudent operational spending,” said Michael Rossi, President and Chief Executive Officer. “We were pleased to have dosed the first patient in our Trial 1201 where our innovative approach to pretargeted radioimmunotherapy has the potential to improve outcomes for patients in the high-risk population with relapsed/refractory non-Hodgkin Lymphoma. Starting in the first quarter of 2025, we began operating as two separate business units, DANYELZA and Radiopharmaceuticals, and in doing so, our reporting highlights DANYELZA’s segment profit in addition to the resource investments we are making to advance our radioimmunotherapy platform. We look forward to sharing updates on our radiopharmaceutical business strategy, including Part A clinical data from Trial 1001, new optimization data, and new planned target programs and anticipated timelines, during our virtual Radiopharmaceutical R&D update on May 28^th.”

Recent Corporate Highlights

• On May 7, 2025, Y-mAbs announced that naxitamab-gqgk (DANYELZA^®) has been recommended by the National Comprehensive Cancer Network^® (“NCCN”) Clinical Practice Guidelines in Oncology (NCCN Guidelines^®) as a NCCN Category 2A treatment option for high-risk neuroblastoma.
• First patient has been dosed in the Company’s CD38-SADA Phase 1 clinical trial (Trial 1201) evaluating Y-mAbs’ Self-Assembly and Disassembly (“SADA”) Pretargeted Radioimmunotherapy (“PRIT”) platform for the treatment of patients with relapsed or refractory non-Hodgkin Lymphoma (r/r NHL). The patient was administered both the first protein dose and the 177Lu-DOTA imaging dose. Trial 1201 is a dose-escalation, open-label, single-arm, multi-center trial investigating the safety and tolerability of the CD38-SADA: 177Lu-DOTA Drug Complex in r/r NHL.
  • Trial 1201 is designed to investigate the pretargeted delivery of the CD38-SADA protein that binds with high affinity to lymphoma cells, followed by the administration of a radioactive 177Lu-DOTA payload to selectively target the tumor-bound CD38-SADA molecules while minimizing radiation to normal tissues. Part A of the clinical trial is CD38-SADA dose escalation with fixed 177Lu-DOTA payload doses to explore the optimal CD38-SADA protein dose and interval between the SADA protein administration and the payload. The primary endpoints of Part A include tumor imaging and occurrence of dose limiting toxicities (“DLT”) in the DLT evaluation period.
• The Company presented preclinical and translational pharmacokinetics (PK) data of CD38-SADA in a poster at the 2025 American Association of Cancer Research (“AACR”) Annual Meeting on April 27, 2025 in Chicago, IL. The poster titled “Preclinical and translational pharmacokinetic (PK) modeling of the self-assembling and disassembling (SADA) bispecific fusion protein CD38-SADA for first-in-human (FIH) pretargeted radioimmunotherapy (PRIT)” characterized the plasma concentrations of CD38-SADA in animal models over time and a range of doses. Utilizing in vitro binding kinetic parameters and PK data generated from three studies in mice, the study characterized the concentration- and time-dependent equilibrium between CD38-SADA tetramers and monomers. Using these data, Y-mAbs conducted a series of appropriately scaled human PK simulations, which informed the design and initial dosing regimen of Trial 1201, the Company’s first-in-human Phase 1 clinical trial (Trial 1201) in patients with r/r NHL.
• Y-mAbs plans to host a virtual Radiopharmaceutical R&D update on Wednesday, May 28, 2025 where the Company will discuss:
  • Part A clinical data from ongoing Phase 1 GD2-SADA clinical trial (Trial 1001), including pharmacokinetic and dosimetry data;
  • Updates around the Company's nonclinical optimization studies for the GD2-SADA asset and plans for clinical implementation; and
  • Radiopharmaceutical pipeline strategy, including new planned target programs and anticipated timelines.
• Following the business realignment strategy announced in January 2025, the Company is now organized into two business units: DANYELZA and Radiopharmaceuticals. The Company’s business units are focused on different products and platforms. They are managed separately as each business unit requires different research and development, marketing and other operational investments. Their segment profit/(loss) from operations include certain non-cash costs.
  

First Quarter 2025 Key Highlights

• Enhanced collaboration with SciClone and other distribution partners with new commercial programs introduced in distribution partners’ territories.
• Continued commercial success with the named patient program for DANYELZA in Turkey with partner INPHARMUS (formerly named TRPharm İlaç Sanayi Ticaret A.Ş. and TRPharm FZ-LLC) and expansion of agreement into new markets.

Financial Results

Revenues

Total revenues for the quarter ended March 31, 2025 were $20.9 million, which was a 5% increase over the $19.9 million of total revenues for the quarter ended March 31, 2024, primarily driven by a $6.7 million increase in Ex-U.S. DANYELZA revenue, partially offset by a $5.2 million decrease in U.S. DANYELZA revenue and $0.5 million decrease related to license revenue recognized in the three months ended March 31, 2024. Total DANYELZA net product revenues for the quarter ended March 31, 2025 were $20.9 million, which was an 8% increase over $19.4 million total DANYELZA net product revenues for the quarter ended March 31, 2024.

The Company’s U.S. DANYELZA net product revenues for the quarter ended March 31, 2025 were $13.4 million, representing a decrease of 28% from the same period in 2024. The decline in the U.S. DANYELZA net product revenues was driven by enrollments in clinical studies and market dynamics.

The Company’s Ex-U.S. DANYELZA net product revenues for the quarter ended March 31, 2025 were $7.5 million, representing an increase of $6.7 million from the same period in 2024. The increase in the Ex-U.S. DANYELZA net product revenues was driven by a $3.8 million increase in net product revenue in Western Asia, where the named patient program launched in late 2024, and increased net product sales in the Eastern Asia, where a new marketing initiative program was introduced in late 2024, and Latin America regions.

As of March 31, 2025, Y-mAbs had delivered DANYELZA to 70 centers across the U.S. since initial launch, with one new account added in the U.S. in the first quarter 2025. During the quarter ended March 31, 2025, approximately 72% of the vials sold in the U.S. were sold outside of Memorial Sloan Kettering Cancer Center (“MSK”), compared to 64% in the fourth quarter ended December 31, 2024.

There was no license revenue for the quarter ended March 31, 2025. During the quarter ended March 31, 2024, the Company had license revenues of $0.5 million, 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.

Cost of Goods Sold

Cost of goods sold was $3.0 million and $2.1 million for the three months ended March 31, 2025 and 2024, respectively. The increase in cost of goods sold in the three months ended March 31, 2025 compared to the same period in 2024, was driven by increased volumes in Ex-U.S. regions which carry a lower gross margin.

Gross Profit

Gross profit stayed consistent at $17.9 million and $17.8 million for the three months ended March 31, 2025 and 2024, respectively.

Gross margins are 86% and 89% for the three months ended March 31, 2025 and 2024, respectively. Gross margin from total revenues decreased in the three months ended March 31, 2025, which was mainly attributable to the decreased U.S. net product revenues, which are at higher margins compared to our Ex-U.S. regions.

Operating Costs and Expenses

Research and Development

Research and development expenses were $11.4 million and $13.3 million for the three months ended March 31, 2025 and 2024, respectively. The $1.9 million decrease in research and development expenses was primarily attributable to a decrease of $0.7 million in clinical trials due to the timing of completion in the Company’s GD2-SADA program, investment in its ongoing SADA PRIT programs, and a $0.9 million decrease in personnel and stock-based compensation costs, partially offset by $0.6 million increase in outsourced manufacturing for investment in the Company’s naxitamab program.

Selling, General, and Administrative

Selling, general, and administrative expenses were $13.1 million for the three months ended March 31, 2025, as compared to $11.4 million for the three months ended March 31, 2024. The $1.7 million increase in selling, general, and administrative expenses was primarily attributable to a $0.8 million increase in personnel and stock-based compensation costs, a $0.5 million charge related to the business realignment expense and $0.4 million in legal expenses recorded in the three months ended March 31, 2025.

Interest and Other Income

Interest and other income for the three months ended March 31, 2025 was $1.4 million compared to $0.4 million for the three months ended March 31, 2024. Interest and other income increased by $1.0 million primarily due to a $1.3 million increase in foreign currency transaction gains, partially offset by a $0.3 million decrease in interest earned from money market fund investments.

Net Loss

Y-mAbs reported a net loss for the quarter ended March 31, 2025, of $5.2 million, or ($0.12) per basic and diluted share, compared to a net loss of $6.6 million, or ($0.15) per basic and diluted share, for the quarter ended March 31, 2024. The decrease in net loss for the quarter ended March 31, 2025 was primarily driven by increased total revenues and increased foreign currency transactional gains, partially offset by increased operating costs and expenses.

Cash and Cash Equivalents

As of March 31, 2025, Y-mAbs had approximately $60.3 million in cash and cash equivalents which, together with anticipated DANYELZA product revenues, is expected to support operations as currently planned into 2027. The Company is currently operating below its anticipated cash investment guidance for the full year 2025. 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 Company continues its efforts to be capital efficient in its operations.

2025 Financial Guidance

Management reiterates its guidance for the full year 2025:

• Anticipated Total Revenues expected to be between $75 million and $90 million;
• Anticipated Total Operating Costs and Expenses, excluding cost of goods sold, expected to be between $116 million and $121 million (Total Operating Costs and Expenses including anticipated cost of goods sold of between $13 million and $15 million is anticipated to be between $129 million and $134 million);
• Anticipated Total Annual Cash Investment expected to be between $25 million and $30 million; and
• Cash and Cash Equivalents anticipated to be sufficient to fund operations as currently planned into 2027.
