Brief Summary:
The purpose of this study is to test the safety of 19(T2)28z1xx CAR T cells in people with relapsed/refractory B-cell cancers. The researchers will try to find the highest dose of 19(T2)28z1xx CAR T cells that causes few or mild side effects in participants. Once they find this dose, they can test it in future participants to see if it is effective in treating their relapsed/refractory B-cell cell cancers. This study will also look at whether 19(T2)28z1xx CAR T cells work against participants' cancer.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 30 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: This is a standard phase I open-label dose-escalation trial. Cohorts of 3-6 patients will be infused with escalating doses of 19(T2)28z1XX CAR T cells to establish the MTD. There are 4 planned dose levels with one additional de-escalation dose level. A 3+3 design will be used to establish the RP2D. Once the RP2D is determined, the study will open to Dose Expansion phase and up to 12 patients with B-cell non-Hodgkin lymphoma (same eligibility criteria as the dose-escalation phase).
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I Study of CD19-Targeted 19(T2)28z1xx Chimeric Antigen Receptor (CAR) Modified T Cells in Adult Patients With Relapsed or Refractory B-cell Malignancies
Actual Study Start Date : July 6, 2020
Estimated Primary Completion Date : July 2024
Estimated Study Completion Date : July 2024

Arm Intervention/treatment
Experimental: 19(T2)28z1xx CAR T cells
Cohorts of 3-6 patients will be infused with escalating doses of 19(T2)28z1XX CAR T cells to establish the RP2D. There are 4 planned flat-dose levels: 25x10^6, 50 x 10^6, 100 x 10^6 and 200 x 10^6 CAR T cells and one de-escalation dose: 12.5 x 10^6 CAR T cells. A standard 3+3 dose escalation design will be implemented starting from dose 1.
Drug: 19(T2)28z1xx CAR T cells
2-7 days following the completion of the conditioning chemotherapy, patients will receive the CAR- T cells by IV infusion over 1-3 days depending on the dose level and formulation of the final CAR- T cells.

Primary Outcome Measures :
  1. Recommended Phase II Dose (RP2D) [ Time Frame: 28 days post infusion ]
    Dose escalation will use a 3+3 design. DLT-evaluable participants are defined as those participants who were infused with 19(T2)28z1XX CAR T cells and who were monitored for toxicities during the first 28 days of post infusion.

Secondary Outcome Measures :
  1. overall response rate (ORR) [ Time Frame: 2 years ]
    Response and progression of the disease will be evaluated in this study using the Lugano Classification
