    Y-mAbs Announces New Interim Analysis of Phase 2 Data for Naxitamab at 2024 ASCO Annual Meeting By Investing.com



    NEW YORK, June 01, 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 announced new interim data from the Phase 2 Trial 201 of naxitamab in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF) in patients with relapsed or refractory high-risk neuroblastoma with residual disease limited to bone and/or bone marrow. The results are summarized in poster presentations scheduled to be presented today, June 1, 2024, at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, IL.

    Improved patient outcomes with extended naxitamab therapy: A poster titled Patterns of improvement following initial response in patients treated with naxitamab for relapsed/refractory high-risk neuroblastoma (poster #10033) demonstrates that continued treatment with naxitamab can further reduce disease following the initial response to naxitamab therapy. The Trial 201 prespecified interim analysis achieved a 50% overall response rate (ORR) in 26 out of 52 patients. Nearly a quarter of patients achieved their first complete response (CR) or partial response (PR) after three or more cycles of naxitamab therapy. Among these patients, most had initial stable disease within specific bone or bone marrow compartments prior to achieving a CR or PR. These results support the rationale for extended naxitamab therapy in patients who do not achieve a CR or PR at first assessment.

    Evolution of adverse events over the course of treatment: A poster titled Naxitamab-related adverse events within and across treatment cycles in patients with relapsed/refractory high-risk neuroblastoma (poster #10032) demonstrates the frequency and patterns of adverse events (AEs) based on the interim analysis of Trial 201. In this analysis, 81% of naxitamab-related AEs were Grade 1 or 2, while Grade ‰¥3 AEs reported in ‰¥10% of patients included hypotension (60% of patients), pain (58%), urticaria (19%), bronchospasm (18%), and abdominal pain (16%). None resulted in treatment discontinuation. Notably, the frequency of naxitamab-related pain Grade 3 AEs decreased from the first cycle (53%) to the second (37%), generally stabilizing thereafter, with frequencies consistent across infusions. Similarly, the frequency of hypotension showed marked reductions across cycles and infusions.

    We are encouraged to see that some patients who did not demonstrate an objective response after initial assessment went on to achieve a complete or partial response after continued naxitamab treatment. In addition, these data provide a practical understanding of the temporal patterns of treatment-related adverse events, said Vignesh Rajah, MBBS, DCH, MRCP (UK), Chief Medical Officer.

    In addition, Dr. Jaume Mora and researchers from the Sant Joan de Déu Barcelona Children’s Hospital in Spain will present results from an independent retrospective analysis of patients treated with naxitamab in combination with chemotherapeutics in a poster titled Naxitamab chemo-immunotherapy regimens other than with irinotecan/temozolomide for patients with relapsed/refractory high-risk neuroblastoma (poster #10037). In this study, 29 patients with mostly chemo-immunotherapy refractory disease received compassionate use of naxitamab plus sargramostim in combination with alternative chemotherapeutics. Importantly, prior sensitivity to chemo-immunotherapy predicted better responses with the new combinations. The safety profiles of the alternative naxitamab chemo-immunotherapy regimens were considered manageable.

    Y-mAbs will be available for comment at booth #35151 on the Exhibition Floor of McCormick (NYSE:) Place.
