Brief summary

This phase I/II trial studies the side effects and best dose of genetically engineered lymphocyte therapy and to see how well it works after peripheral blood stem cell transplant (PBSCT) in treating patients with high-risk, intermediate-grade, B-cell non-Hodgkin lymphoma (NHL). Genetically engineered lymphocyte therapy may stimulate the immune system in different ways and stop cancer cells from growing. Giving rituximab together with chemotherapy before a PBSCT stops the growth of cancer cells by stopping them from dividing or killing them. Giving colony-stimulating factors, such as filgrastim (G-CSF), or plerixafor helps stem cells move from the bone marrow to the blood so they can be collected and stored. More chemotherapy or radiation therapy is given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy. Giving genetically engineered lymphocyte therapy after PBSCT may be an effective treatment for NHL.

Detailed description

PRIMARY OBJECTIVES: I. To assess the safety of cellular immunotherapy utilizing ex vivo expanded autologous central memory T cell (TCM)-enriched cluster of differentiation (CD)8+ T cells genetically-modified to express a CD19-specific chimeric antigen receptor (CAR) in conjunction with a standard myeloablative autologous hematopoietic stem cell transplantation (aHSCT) for research participants with high-risk intermediate grade B-lineage non-Hodgkin lymphomas who have relapsed after primary therapy, or who did not achieve complete remission with primary therapy. (Phase I) II. To determine the maximum tolerated dose (MTD) on dose limiting toxicities (DLTs) and to describe the full toxicity profile. (Phase I) III. To determine the rate of research participants receiving TCM-enriched CD8+ T cells genetically-modified to express a CD19-specific CAR for which the transferred cells are detected in the circulation 28 days (+/- 3 days) by woodchuck hepatitis virus post-transcriptional regulatory element (WPRE) quantitative (Q)-polymerase chain reaction (PCR). (Phase II) SECONDARY OBJECTIVES: I. To determine the tempo, magnitude, and duration of engraftment of the transferred T cell product as it relates to the number of cells infused. (Phase II) II. To study the impact of this therapeutic intervention on the development of CD19+ B-cell precursors in the bone marrow as a surrogate for the in vivo effector function of transferred CD19-specific T cells. (Phase II) III. To describe the progression-free and overall survival of treated research participants on this protocol. (Phase II) OUTLINE: This is a phase I, dose-escalation study of genetically engineered lymphocyte therapy followed by a phase II study. Patients receive standard salvage chemotherapy per standard practice and undergo standard mobilization for stem cell collection with filgrastim and/or plerixafor. Some patients may also receive rituximab intravenously (IV) within 4 weeks of transplant. Patients receive standard myeloablative conditioning followed by autologous PBSCT. Patients then undergo infusion of ex vivo expanded autologous TCM-enriched CD8+ T cells expressing CD19-specific CAR on day 2 or 3 after transplant. After completion of study treatment, patients are followed up periodically for at least 15 years.

Pre-assignment details

Three additional participants underwent leukapheresis, however, two were ineligible for transplant and the third refused additional treatment and therefore were not assigned a dose level.
