Study Arms (1)

CD19-targeted chimeric antigen receptor T-cell

EXPERIMENTAL

Patients will receive a lymphodepletion chemotherapy with fludarabine plus cyclophosphamide for three consecutive days(Day -5 to Day -3) before infusion of CD19-targeted chimeric antigen receptor T-cell (CD19 CAR-T). Patients will receive the CD19 CAR-T(also known as PL001) infusion on Day 0.

Biological: CD19-targeted chimeric antigen receptor T-cell

Interventions

Drug: Fludarabine patients will receive a lymphodepletion chemotherapy with Fludarabine 25 mg/m2/day IV for 3 days on Day-5 to Day-3(a safe window for a small subset of patients will be D -7 to D -3). Drug: Cyclophosphamide patients will receive a lymphodepletion chemotherapy with cyclophosphamide 300 mg/m2/day IV for 3 dys Day-5 to Day-3(a safe window for a small subset of patients will be D -7 to D -3). Biological: CD19 CAR-T CD19 CAR-T cells will be administered using as a single dose at 0.1-9\*10\^6 cells/kg on Day 0 after completion of the lymphodepletion chemotherapy. The body weight calculated for PL001 dose is the actual body weight on the day of leukapheresis.

Model Details: This study is a multiple-center, non-randomized, open-label, phase 1/2 study. Lymphodepletion chemotherapy (intravenous infusion of fludarabine plus cyclophosphamide will be administered for 3 consecutive days before the day of PL001 dosing (Day 0) and should take place within Day -5 to Day -3 (a safe window for a small subset of patients will be D -7 to D -3). This study will test two dose levels of PL001, dose level 1 and dose level 2. In Phase 1, doses will be tested in the modified "3 + 3" design initiating with dose level 1. The primary objective of Phase 1 is to assess the safety of PL001 and find the recommended phase 2 dose. Phase 2 expansion cohort will receive PL001 at the recommended dose determined in Phase 1. Efficacy evaluations using computed tomography (CT) and positron emission tomography (PET) will be performed at 1, 3, 6, 9, and 12 months.
