Randomized Phase 2 Study of Iberdomide Maintenance Therapy Following Idecabtagene Vicleucel CAR-T in Multiple Myeloma Patients

This phase II trial compares iberdomide maintenance therapy to disease monitoring for improving survival in patients who have received idecabtagene vicleucel (a type of chimeric antigen receptor T-cell [CAR-T] therapy) for multiple myeloma. The usual approach after treatment with idecabtagene vicleucel is to monitor the multiple myeloma without giving myeloma medications. There is currently no medication approved specifically for use after idecabtagene vicleucel treatment. Upon administration, iberdomide modifies the immune system and activates immune cells called T-cells, which could enhance the effectiveness of idecabtagene vicleucel. Iberdomide may keep multiple myeloma under control for longer than the usual approach (disease monitoring) after idecabtagene vicleucel, and may help multiple myeloma patients live longer.
