Oncopeptides AB (publ) - announced that the FDA, has approved Pepaxto (melphalan flufenamide, also known as melflufen), in combination with dexamethasone, for the treatment of adult patients with relapsed or refractory multiple myeloma, who have received at least four prior lines of therapy and whose disease is refractory to at least one proteasome inhibitor, one immunomodulatory agent, and one CD38-directed monoclonal antibody. Oncopeptides will begin promoting Pepaxto to healthcare professionals across the U.S. immediately and expects a labeled product in distribution centers and specialty pharmacies within approximately two weeks. Pepaxto is the first anticancer peptide-drug conjugate approved by the FDA. The product has been granted accelerated approval based on the phase II HORIZON study in relapsed or refractory multiple myeloma.

This multi-center single arm study evaluated 157 patients with relapsed or refractory multiple myeloma, of whom 97 were triple-class refractory and had received at least four prior lines of treatment. The Overall Response Rate for the patients within this group of patients with refractory multiple myeloma was 23.7% and the Median Duration of Response was 4.2 months . Furthermore, melflufen in combination with dexamethasone demonstrated activity in a subset of patients with Extra Medullary Disease (41%), an aggressive and resistant disease associated with a poor prognosis .
