Recurrent Plasma Cell Myeloma Refractory Plasma Cell Myeloma | Biological: Autologous Anti-BCMA-CAR-expressing CD4+/CD8+ T-lymphocytes FCARH143 Drug: Cyclophosphamide Drug: Fludarabine Procedure: Leukapheresis | Phase 1 |
PRIMARY OBJECTIVE:
I. To evaluate the safety of adoptive therapy with ex vivo expanded autologous CD8+ plus CD4+ T cells transduced to express a human B cell maturation antigen (BCMA)-targeting chimeric antigen receptor (CAR) for patients with relapsed or treatment refractory multiple myeloma.
SECONDARY OBJECTIVES:
I. To determine the duration of in vivo persistence and the phenotype of long lived CAR-T cells.
II. To determine the degree to which adoptively transferred T cells traffic to multiple myeloma (MM) cells in the bone marrow (BM) and function in vivo.
III. To estimate the antitumor activity of adoptively transferred BCMA-specific CAR-expressing T lymphocytes (BCMA CAR-T cells).
OUTLINE: This is a dose-escalation study of BCMA-specific CAR-expressing T lymphocytes.
Patients undergo leukapheresis to obtain their immune cells, from which CAR-T cells are produced. A few weeks later, patients then receive cyclophosphamide and fludarabine on days -4 to -2. Beginning 36-96 hours after chemotherapy, patients receive BCMA-specific CAR-expressing T lymphocytes intravenously (IV) over 20-30 minutes on day 0. Patients may receive a second dose of BCMA-specific CAR-expressing T lymphocytes IV with or without additional cytoreductive chemotherapy at the discretion of the principal investigator or their designee (sub-investigator).
After completion of study treatment, patients are followed up at 60, 90, 120, 180, and 365 days and then annually up to 15 years.
