Inhibrx Biosciences announced that the U.S. FDA has accepted for filing its Biologics License Application seeking approval of ozekibart for the treatment of patients with unresectable or metastatic conventional chondrosarcoma. The FDA has not identified any filing review issues at this time and has assigned a Prescription Drug User Fee Act goal date of April 14, 2027. "The FDA's acceptance of our BLA for ozekibart is a monumental milestone for Inhibrx and, more importantly, for the chondrosarcoma community," said Mark Lappe, CEO of Inhibrx. "Chondrosarcoma is an aggressive and devastating bone cancer and there are currently no approved therapies for patients suffering from this disease.
