Description

Summary

This is a global, open-label, multi-arm, multi-cohort, multi-center, phase 1/2 study to determine the safety, tolerability, efficacy, PK of bb2121 in combination with other therapies in adult subjects with R/RMM. The following combinations will be - Arm A will test bb2121 in combination with CC-220 (± low-dose dexamethasone) - Arm B will test bb2121 in combination with BMS-986405 (JSMD194) - Arm C will test bb2121 in combination with one of the following standard triplet regimens: 1) Daratumumab (DARA) in combination with pomalidomide (POM) and low-dose dexamethasone (DPd); 2) Pomalidomide (POM) in combination with bortezomib (BTZ) and low-dose dexamethasone (PVd) Combination agents being tested may be administered before, concurrently with and/or following (ie, maintenance) bb2121 infusion. The study will consist of 2 parts: dose finding (Phase 1) and dose expansion (Phase 2). Dose expansion may occur in one or more arms.

  • Arm A Cohort 2 and Arm C: Participant has received prior treatment with an immunomodulatory agent for at least 2 consecutive cycles.
  • Evidence of PD during or within 6 months (measured from the last dose of any drug within the regimen) of completing treatment with the last antimyeloma regimen before study entry.
  • Participant achieved a response (minimal response [MR] or better) to at least 1 prior treatment regimen.
  • Participant has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
