FDA Grants Y-mAbs Pediatric Disease Designation

FDA has granted Y-mAbs Therapeutics a rare pediatric disease designation for the company’s lutetium-labeled omburtamab antibody program for treating medulloblastoma. The therapy 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 central nervous system/leptomeningeal metastases tumors in adults. The designation makes Y-mAbs eligible for a priority review voucher upon potential approval of a BLA for this rare pediatric cancer. The company currently has one FDA approved product, Danyelza (naxitamab-gqgk), which targets tumors that express GD2, and one pivotal-stage product candidate, omburtamab, which targets tumors that express B7-H3.
