Y-mAbs Announces Frontline Data for DANYELZA® (naxitamab-gqgk) in High-Risk Neuroblastoma


NEW YORK, June 04, 2021 (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, antibody-based therapeutic products for the treatment of cancer, today announced that Dr. Jaume Mora, M.D., Ph.D. from SJD Barcelona Children's Hospital will present frontline data for DANYELZA and GM-CSF for consolidation of high-risk neuroblastoma (“HR-NB”) patients in complete remission at the American Society of Clinical Oncology (“ASCO”) Virtual Annual Meeting on June 4, 2021

Patients received five cycles of DANYELZA and GM-CSF in a compassionate use setting for consolidation of HR-NB in first or subsequent complete remission (“CR”). DANYELZA was administered in an outpatient setting on days 1, 3 and 5 at 9.0 mg/kg/cycle in combination with GM-CSF, and treatment cycles were repeated every four weeks. From June 2017 to November 2020, a total of 73 patients were treated: 55 patients (75%) in first CR and 18 patients (25%) in second or more CR. The three-year event free survival (“EFS”) for patients in first CR was 74% and 19% for second or later CR. The three-year overall survival (“OS”) for the patients in first CR was 92% and 66% for second or later CR patients. Dr. Mora reported two-year EFS and OR at the Company’s R&D Day in December 2020 and those data have been maintained for the three-year follow up.

“We are very pleased to report such encouraging three-year follow-up data in frontline high-risk neuroblastoma for DANYELZA in patients that are in full remission after the induction regiment,” stated Thomas Gad, founder, Chairman and President.

Dr. Claus Moller, Chief Executive Officer, continued, “We are excited to see the three-year data holding up so well for the frontline patients and, if approved, we believe this could potentially significantly differentiate DANYELZA from other existing therapies.”

Researchers at MSK developed DANYELZA, which is exclusively licensed by MSK to Y-mAbs. As a result of this licensing arrangement, MSK has institutional financial interests in the product.
