简要总结
This feasibility trial studies the efficacy of administering iberdomide (CC-220) as a priming agent prior to leukapheresis in patients with relapsed/refractory multiple myeloma (RRMM) who are already planned for standard-of-care CAR-T therapy. Giving iberdomide before CAR-T may improve T cell fitness which may improve CAR-T expansion kinetics and response after infusion.
详细描述
In this feasibility study, patients with RRMM planned for standard of care CAR-T will be approached for consent for enrollment. Participating patients will receive one 28-day cycle of iberdomide at a dose of 1.0 mg daily, using a dosing schedule of 1.0 mg once daily for 21 days followed by 7 days off. After completion of the 28-day cycle, patients will proceed with leukapheresis on day 29 of therapy, with allowance for up to a 14-day delay in leukapheresis if needed. Blood samples will be collected on day 1 (prior to iberdomide exposure) and on the day of leukapheresis to compare T cell profiling before and after iberdomide priming. After leukapheresis, patients will proceed with standard of care management, including bridging therapy if indicated, until CAR-T infusion. After infusion, blood samples will be collected daily during initial hospitalization, then weekly for 1 month, and then monthly for up to 1 year. Blood samples will be evaluated for maximal CAR-T and ALC expansion and CAR-T persistence. Patients will be monitored per standard of care protocols for clinical efficacy and toxicity after CAR-T therapy for up to 1 year.
