DUBLIN – Oncopeptides AB has withdrawn its troubled multiple myeloma
drug Pepaxto (melphalan flufenamide) from the U.S. market, less than eight months after receiving an accelerated approval from the FDA. The move comes less than a week before the FDA’s Oncologic Drugs Advisory Committee was due to consider the drug’s safety profile because of data anomalies that surfaced over the summer.
DUBLIN – Shares in Oncopeptides AB dropped 26% July 8 on news that the FDA had placed a partial clinical hold on a raft of trials involving its newly approved multiple myeloma drug Pepaxto (melphalan flufenamide; melflufen), following a bizarre incident involving the incomplete handover to an independent review committee of data from a phase III head-to-head trial in myeloma, which had pitted melflufen against Pomalyst (pomalidomide).
Oncopeptides AB remains on track for an NDA filing in the second quarter for its peptide-drug conjugate, melflufen, in relapsed refractory multiple myeloma (RRMM).
