Summary
PRIMARY OBJECTIVES:
I. To establish and confirm the safety and dose of iberdomide as maintenance after idecabtagene vicleucel (ide-cel) CAR-T. (Safety run-in) II. To assess whether iberdomide maintenance therapy after idecabtagene vicleucel CAR-T cell therapy increases progression-free survival (PFS) relative to observation without additional therapy. (Randomized phase II)
SECONDARY OBJECTIVES:
I. To demonstrate anti-tumor activity, defined as conversion from non-minimal residual disease (MRD) complete response (CR)/stringent CR (sCR) status to MRD-negative CR/sCR, as well as improvement in PFS in the safety run-in cohort. (Safety run-in) II. To estimate the rate of conversion from MRD-positive at baseline to MRD-negative at any time point post-initiation of iberdomide maintenance or observation without additional therapy. (Key secondary objective; Randomized phase II) III. To estimate overall survival (OS) distribution post-initiation of iberdomide maintenance or observation without additional therapy. (Key secondary objective; Randomized phase II) IV. To estimate the minimal residual disease (MRD)-negativity rate at pre-registration and at one year post-initiation of iberdomide maintenance or observation without additional therapy. (Randomized phase II) V. To estimate rate of deepening hematological response among patients with measurable multiple myeloma (MM) post-initiation of iberdomide maintenance or observation without additional therapy. (Randomized phase II) VI. To evaluate the safety profile of iberdomide maintenance. (Randomized phase II) VII. To evaluate the peripheral blood immunophenotype before and during iberdomide maintenance or observation without additional therapy. (Randomized phase II) VIII. To evaluate persistence of CAR-T cells with iberdomide maintenance or observation without additional therapy. (Randomized phase II)
