Y-mAbs’ 177Lu-omburtamab-DTPA for the Treatment of Patients with Medulloblastoma Granted Rare Pediatric Disease Designation by FDA

NEW YORK, Oct. 07, 2021 (GLOBE NEWSWIRE) — Y-mAbs Therapeutics, Inc. (“Y-mAbs” or the “Company”) (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 the U.S. Food and Drug Administration (“FDA”) has granted Rare Pediatric Disease Designation (“RPDD”) for the Company’s lutetium labelled omburtamab antibody program for the treatment of medulloblastoma.

¹⁷⁷Lu-omburtamab-DTPA, a monoclonal B7-H3 antibody that has been radiolabeled with lutetium-177, is currently in a multicenter Phase 1 clinical trial in pediatric patients with refractory medulloblastoma, and in a multicenter Phase 1 clinical trial targeting B7-H3 positive CNS/LM tumors in adults. We believe that both indications address clear unmet medical needs.   

“The RPDD makes us eligible for a Priority Review Voucher (“PRV”) upon potential approval of the biologics license application for this rare pediatric cancer. Among our leading compounds under development, four now have RPDDs, and this designation for ¹⁷⁷Lu-omburtamab-DTPA further increase our chances of ultimately receiving multiple PRVs,” said Thomas Gad, founder, Chairman and President.

Dr. Claus Moller, Chief Executive Officer, further notes, “We are dedicated to bring ¹⁷⁷Lu-omburtamab-DTPA to patients who desperately need alternative methods of treatment. We are very pleased by this recognition by the FDA and look forward to expanding the ongoing Phase 1 studies with ¹⁷⁷Lu-omburtamab-DTPA into separate Phase 2 arms.”

Researchers at Memorial Sloan Kettering Cancer Center (“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 product.
