Investor Q&A

What does this mean for Oncopeptides?

The documents posted in the public docket contain argumentation from the involved parties as well as procedural information, such as an upcoming meeting on October 2. The foundational fact remains the same: the FDA is looking to withdraw the approval of Pepaxto from the U.S. market, a decision which we have appealed. We look forward to seeing the process through.


Could you estimate the chance of success of this appeal?

We don´t want to speculate on that. While our strong confidence in the product and its ability to help patients suffering from Multiple Myeloma also in the U.S. remains, we need to remember that we currently don´t market Pepaxto in the U.S.

Oncopeptides’ full strategic focus is on the product roll-out in Europe, where we have a marketing authorization and an established marketing company.
