Y-mAbs Therapeutics, Inc. (YMAB) generates news that spans commercial oncology performance, clinical development milestones in radioimmunotherapy, and significant corporate transactions. Company announcements consistently describe Y-mAbs as a commercial-stage biopharmaceutical company focused on novel radioimmunotherapy and antibody-based therapeutic products for the treatment of cancer, with its lead commercial asset DANYELZA® (naxitamab-gqgk) for relapsed or refractory high-risk neuroblastoma.
News coverage for Y-mAbs frequently highlights financial results and segment updates, including quarterly revenue from DANYELZA, ex-U.S. distribution trends, and the allocation of resources between the DANYELZA and Radiopharmaceuticals business units. Earnings releases often discuss cost of goods sold, research and development spending, selling, general, and administrative expenses, and net loss, along with management commentary on operating strategy and capital efficiency.
Another major category of YMAB news involves clinical and R&D developments in the company’s SADA Pretargeted Radioimmunotherapy (PRIT) platform. Press releases describe progress in the GD2-SADA Phase 1 Trial 1001 in GD2-expressing solid tumors, including pharmacokinetic and dosimetry data, and the initiation of the CD38-SADA Phase 1 Trial 1201 in relapsed or refractory non-Hodgkin lymphoma. Y-mAbs also reports on preclinical pharmacokinetic modeling, optimization of radiohaptens such as “Proteus,” and expansion of its radiopharmaceutical pipeline into additional oncology franchises.
Y-mAbs news also covers regulatory and guideline recognition, such as the inclusion of naxitamab-gqgk (DANYELZA) as a Category 2A treatment option in the National Comprehensive Cancer Network® (NCCN®) Clinical Practice Guidelines in Oncology for Neuroblastoma. These updates provide context on how DANYELZA is positioned within clinical practice for high-risk neuroblastoma.
A key theme in recent YMAB headlines is corporate transformation and acquisition activity. In August 2025, Y-mAbs announced that SERB Pharmaceuticals, through an affiliate, agreed to acquire the company in an all-cash transaction at $8.60 per share, with an equity value of approximately $412 million, as described in joint press releases and Form 8-K filings. Subsequent news and SEC filings report the commencement and completion of the tender offer, the closing of the merger, and the resulting delisting of Y-mAbs common stock from the Nasdaq Global Select Market.
Investors and observers following YMAB-related news can expect updates on quarterly financial performance, DANYELZA commercial metrics, clinical trial progress for SADA-based programs, radiopharmaceutical R&D strategy, and the implications of the company’s acquisition by an affiliate of SERB Pharmaceuticals. This news flow provides insight into both the historical public-company phase of Y-mAbs and its transition into a privately held subsidiary within a larger specialty pharmaceutical group.
