A Multicenter Study of Belantamab Mafodotin and Mezigdomide in Patients With Relapsed Multiple Myeloma (BELAMI)

A Multicenter Phase 2 Study of Belantamab Mafodotin and Mezigdomide in Combination With a Phase Ib Safety Run in Patients With Relapsed Multiple Myeloma Following BCMA-targeting CAR-T Cells or Bispecific Antibodies

The BELAMI trial is an open label, multicenter, phase 2 study for patients with MM who relapsed following BCMA-directed CAR-T cells or bispecific antibodies with a Phase Ib Safety run-in.

The primary hypothesis of this study is that a combination of ADC targeting BCMA and CELMoD will be efficient for these patients.

詳細な説明

CAR-T cells and bispecific antibodies targeting BCMA have been approved in the treatment of patients with multiple myeloma (MM), at late stage of disease. Data from real-world situations showed poor outcomes of patients who relapsed following these treatments. Belantamab mafodotin is an antibody-drug conjugate (ADC) targeting BCMA. Mezigdomide is a novel oral CELMoD® agent (oral cereblon-modulating) with enhanced tumoricidal and immune-stimulatory effects compared to immunomodulatory drugs. The ALGONQUIN trial demonstrated that the anti-myeloma activities of Belantamab mafodontin were significantly increased by immunomodulatory drugs. In this context, investigator aim to evaluate Belantamab mafodontin in association with Mezigdomide.
