Study Details

Study Description

Brief Summary

This phase I trial evaluates the best dose, possible benefits and/or side effects of fludarabine and cyclophosphamide with or without rituximab before CD19 chimeric antigen receptor T cells in treating patients with diffuse large B-cell lymphoma that has come back (relapsed) or has not responded to previous treatment (refractory). T-cells are a normal part of the immune system. To make the T-cell medication, T-cells are taken from the blood and altered in a laboratory. They are then returned to the body. The altered T-cells will latch on to a specific part of the cancer cells and hopefully kill them. Once the T-cells have been altered in the laboratory, they are called "CAR T-cells." CAR is short for "chimeric antigen receptors." These are structures on the surface of cells that allow the altered T-Cells to find and destroy the cancer cells. Another part of the T-Cell medication is called "CD19." This part is called a "biomarker." Biomarkers help doctors determine whether a cancer is getting worse and whether medications are working to stop it. The chemotherapy drugs that are given before the T-Cell therapy are cyclophosphamide, fludarabine and rituximab. Rituximab is an immunotherapy drug. These chemotherapy drugs will reduce the number of normal (unaltered) T-Cells in the body to make room for the altered T-cells to kill the cancer cells. Giving fludarabine and cyclophosphamide with or without rituximab before CD19 CAR T cell therapy may help improve response to CD19 CAR T cell therapy in patients with diffuse large B-cell lymphoma.

Phase 1

Detailed Description

PRIMARY OBJECTIVES:I. To examine the feasibility to manufacture autologous CD19 CAR T cells at a minimum target dose of 1.0 x 10^6 cells/kilogram using the CliniMACS automated system.II. To determine the safety of administering high-dose conditioning chemotherapy with cyclophosphamide and fludarabine with rituximab prior to CD19 CAR-T cell therapy in patients with relapsed (R)/refractory (R) diffuse large B cell lymphoma (DLBCL) and to find the recommended regimen after phase II dose for this therapy.III. To determine the safety of infusion of chimeric antigen receptor T cells targeting CD19 in adults with R/R DLBCL.

SECONDARY OBJECTIVES:I. To describe the toxicities related to CD19 targeted CAR T cells.II. To describe the overall response rate (ORR) and complete response (CR) rate of relapsed DLBCL treated with CD19 CAR T cells.III. To assess other response variables including overall survival (OS), progression free survival (PFS), and event free survival (EFS).

    4. Overall survival [From the start of the conditioning lymphodepletion chemotherapy on day -6 until death, assessed at 1 year]

      Will be estimated using Kaplan and Meier methods. Comparison of time-to-event endpoints by important subgroups will be made using the log-rank test.

    5. Progression free survival [From the start of the conditioning lymphodepletion chemotherapy regimen until the documentation of disease progression or death due to any cause, whichever occurs first, assessed at 1 year]

      Will be estimated using Kaplan and Meier methods. Comparison of time-to-event endpoints by important subgroups will be made using the log-rank test.

    6. Event free survival [From the date of day -6 of lymphodepleting conditioning therapy to the date of first documented progression, initiation of new anti-lymphoma treatment, or death, assessed at 1 year]
