Y-mAbs Announces Pivotal Data for Omburtamab
NEW YORK, Oct. 03, 2022 (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 clinical data on the Company’s product candidate OMBLASTYS® (131I-omburtamab) for the treatment of CNS/leptomeningeal metastasis from neuroblastoma. Data was presented by Dr. Kim Kramer from Memorial Sloan Kettering Cancer Center (“MSK”) at the International Society of Pediatric Oncology (“SIOP”) Annual Congress held September 28 through October 1, 2022, in Barcelona, Spain.
In an oral presentation, Dr. Kramer presented interim results for 32 patients enrolled in the Company’s ongoing pivotal 101 multicenter study of omburtamab radiolabeled with Iodine-131. The results showed a twelve-month overall survival (“OS”) of 73.5%, with a median follow-up of 25 months. Further, the interim results showed an objective response rate (“ORR”) of 31.3% in the patients with measurable disease after central review based on Response Assessment in Neuro-Oncology (“RANO”) criteria and European Association of Neuro-Oncology (“EANO")/European Society for Medical Oncology (“ESMO”) criteria, and that a total of 75.0% of the patient with measurable disease achieved disease control. Serious Adverse Events (“SAE”) was found in 40.6% of the patients and were mostly related to myelosuppression.
“We are excited to report these data that together with Study 03-133 is the basis of our BLA,” said Thomas Gad, President, and Interim Chief Executive Officer. “The disease burden these patient and their families are facing represent a significant unmet medical need, which we hope to be able to address with OMBLASTYS after our PDUFA date on November 30, 2022.”
Researchers at MSK developed omburtamab, which is exclusively licensed by MSK to Y-mAbs. As a result of this licensing arrangement, MSK has institutional financial interests in the compound.
