Brief Summary:
This phase I trial studies the safety, side effects, best dose and effectiveness of mezigdomide (CC-92480) when given after idecabtagene vicleucel (Abecma chimeric antigen receptor \[CAR\] T-cell therapy) in patients with multiple myeloma that has come back after a period of improvement (relapsed). CC-92480 works by binding to a protein called CRBN that triggers the breakdown of proteins: Ikaros and Aiolos, leading to cell death in multiple myeloma cells. Giving mezigdomide after Abecma CAR T cell therapy may extending the amount of time that the CAR T cells persist in the body in patients with relapsed multiple myeloma.
Detailed Description:
PRIMARY OBJECTIVE:
I. To evaluate the safety and tolerability of mezigdomide (CC-92480) given post idecabtagene vicleucel when administered as a continued therapy.
SECONDARY OBJECTIVES:
I. To evaluate the anti-tumor activity of mezigdomide (CC-92480) when administered post idecabtagene vicleucel.
II. To determine the persistence of CAR T cells at day 90 (D90), day 180 (D180), and day 365 (D365) after start of mezigdomide (CC-92480) therapy.
EXPLORATORY OBJECTIVES:
I. To assess levels of serum BCMA monthly at day 1 of every cycle. II. To assess the effects of mezigdomide (CC-92480) on non-cancer immune cells in the peripheral blood and bone marrow samples.
OUTLINE: This is a dose-escalation study of mezigdomide.
Starting between 30 and 90 days after infusion of idecabtagene vicleucel, patients receive mezigdomide orally (PO) on days 1-21 or days 1-14 of each cycle. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo positron emission tomography (PET)/computed tomography (CT) during screening. Patients also undergo bone marrow aspiration and blood sample collection throughout the study.
After completion of study treatment, patients are followed up at 30 days, every 3 months within 1 year of start of treatment, and then every 6 months until progression or for up to 2 years.
