What was measured

Toxicity graded using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 No patients received more than one CAR T cell infusion, so AE assessment period was only 28 days after first and only CAR T infusion for all patients.

Groups in this outcome

Treatment (Chemotherapy, BCMA CAR-T Cells) at Dose Level 1

Patients undergo leukapheresis. Patients then receive cyclophosphamide and fludarabine on days -4 to -2. Beginning to 36-96 days after chemotherapy, patients receive BCMA-specific CAR-expressing T lymphocytes 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). Arm 1 contains patients treated as dose level 1 (50 x 10\^6 EGFRt cells) Autologous Anti-BCMA-CAR-expressing CD4+/CD8+ T-lymphocytes FCARH143: Given IV Cyclophosphamide: Given IV Fludarabine: Given IV Leukapheresis: Undergo leukapheresis

Treatment (Chemotherapy, BCMA CAR-T Cells) at Dose Level 2

Patients undergo leukapheresis. Patients then receive cyclophosphamide and fludarabine on days -4 to -2. Beginning to 36-96 days after chemotherapy, patients receive BCMA-specific CAR-expressing T lymphocytes 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). Arm 2 contains patients treated as dose level 2 (150 x 10\^6 EGFRt cells) Autologous Anti-BCMA-CAR-expressing CD4+/CD8+ T-lymphocytes FCARH143: Given IV Cyclophosphamide: Given IV Fludarabine: Given IV Leukapheresis: Undergo leukapheresis

Treatment (Chemotherapy, BCMA CAR-T Cells) at Dose Level 3

Patients undergo leukapheresis. Patients then receive cyclophosphamide and fludarabine on days -4 to -2. Beginning to 36-96 days after chemotherapy, patients receive BCMA-specific CAR-expressing T lymphocytes 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). Arm 3 contains patients treated as dose level 3 (300 x 10\^6 EGFRt cells) Autologous Anti-BCMA-CAR-expressing CD4+/CD8+ T-lymphocytes FCARH143: Given IV Cyclophosphamide: Given IV Fludarabine: Given IV Leukapheresis: Undergo leukapheresis

Treatment (Chemotherapy, BCMA CAR-T Cells) at Dose Level 4

Patients undergo leukapheresis. Patients then receive cyclophosphamide and fludarabine on days -4 to -2. Beginning to 36-96 days after chemotherapy, patients receive BCMA-specific CAR-expressing T lymphocytes 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). Arm 4 contains patients treated as dose level 4 (450 x 10\^6 EGFRt cells) Autologous Anti-BCMA-CAR-expressing CD4+/CD8+ T-lymphocytes FCARH143: Given IV Cyclophosphamide: Given IV Fludarabine: Given IV Leukapheresis: Undergo leukapheresis
