Dose Escalation Phase: CAR-20/19-T transduced with a lentiviral vector to express an anti CD19 and anti CD20 tandem receptor coupled to CD3ζ and 4-1BB signaling domains will be administered by IV injection. Patients will receive one of four dose levels based the study protocol. Cells will be given over 2 days, 30% of cells infused on Day 0 and 70% of cells infused on Day 1 in the Phase 1 portion and as a single infusion in the Phase 1b portion. CAR-20/19-T cells (1.0 x10^5 CAR-20/19-T cells/kg): CAR-20/19-T cells will be administered either fresh or thawed after cryopreservation by IV injection. Phase 1 Dose Level 0: 2.5 x10^5 CAR-20/19-T cells/kg (starting dose level) |
