Pepaxto (melphalan flufenamide) is an anticancer peptide-drug conjugate indicated for use in combination with dexamethasone for the treatment of adult patients with relapsed or refractory multiple myeloma.
On October 22, 2021, Oncopeptides announced the decision to voluntarily withdraw Pepaxto from the U.S. market. The decision was made following consultation with the U.S. FDA regarding the results of the Phase 3 OCEAN study, which showed an overall survival in the intent-to-treat population with a hazard ratio of 1.104.

- Pepaxto is administered intravenously over 30 minutes on Day 1 of each 28-day treatment cycle, in combination with dexamethasone.
