SUCCESSOR-1 Trial Summary

This trial is testing a new combo - CC-92480, bortezomib, and dexamethasone - against the standard of care - pomalidomide, bortezomib, and dexamethasone - for patients with multiple myeloma who have failed 1-3 prior treatments and have been treated with lenalidomide before.

Who is the study for?
This trial is for people with Multiple Myeloma who've had 1-3 previous treatments and were previously treated with lenalidomide. They must have measurable disease, responded at least minimally to past therapy, and not have had a poor reaction or no response to bortezomib. Those who progressed on proteasome inhibitors recently or have been treated with mezigdomide/pomalidomide can't join.Check my eligibility
What is being tested?
The study compares two drug combinations for relapsed/refractory Multiple Myeloma: Mezigdomide with Bortezomib and Dexamethasone (MeziVd) versus Pomalidomide with the same additional drugs (PVd). It aims to see which combo works better after prior therapies including lenalidomide.See study design
What are the potential side effects?
Possible side effects include reactions related to immune system suppression such as infections, blood clots, fatigue, gastrointestinal issues like nausea or constipation, nerve damage that may cause pain or numbness, and potential blood cell count changes leading to anemia or bleeding risks.
