September 20, 2022
STOCKHOLM — September 20, 2022 — Oncopeptides AB (publ) (Nasdaq Stockholm: ONCO), a biotech company focused on research and development of therapies for difficult-to-treat hematological diseases, today announces that the US Food and Drug Administration (FDA), has published the Briefing Book for the Oncologic Drugs Advisory Committee (ODAC) meeting on September 22, 2022. The purpose of the meeting is to obtain the advisory committee´s input regarding the benefit/risk of Pepaxto[®] (melphalan flufenamide, also called melflufen) for the currently indicated patient population.

“We have confidence in our science and data and look forward to discussing the results of the phase 3 OCEAN study during the ODAC meeting, which contribute important and unexpected learnings about Pepaxto, pomalidomide, and the immunomodulatory drug class (IMiDs),” says Jakob Lindberg, CEO of Oncopeptides. “EMA assessed the OCEAN study as a study that met its primary endpoint of superior PFS with true heterogeneity of survival benefit across relevant patient populations. That is in line with the scientific conclusions and position from Oncopeptides with relevant learnings from the heterogenous OCEAN survival result guiding future treatment and development.”

“Oncopeptides is committed to enhancing treatment success in patients with RRMM treated with Pepaxto,” says Klaas Bakker, MD, PhD, Executive Vice President and Chief Medical Officer. “That is why we are proactively communicating that the use of Pepaxto should be limited to only patients without prior autologous stem cell transplant or patients with post-ASCT progression more than 36 months after transplant regardless of the outcome of the ODAC meeting. “

The briefing book contains background information prepared by the FDA and Oncopeptides for the panel members of the ODAC. The FDA will not issue a final determination on the issues discussed until input from the advisory committee process has been considered and all reviews have been finalized. This may be affected by issues not discussed at the ODAC meeting. Background material and the link to the live webcast can be reached at
