CD19-CD34t Metabolically Programmed CAR T-Cell Therapy for the Treatment of Patients with CD19 Positive Relapsed or Refractory B-Cell Non-Hodgkin Lymphoma, Chronic Lymphocytic Leukemia, or Small Lymphocytic Lymphoma
This phase Ib trial tests the safety and effectiveness of CD19-CD34t metabolically programmed chimeric antigen receptor (CAR) T-cell therapy in treating patients with CD19 positive B-cell non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL), or small lymphocytic lymphoma (SLL) that has come back after a period of improvement (relapsed) or does not respond to treatment (refractory). Although there are many commonly used treatments, disease that does not respond to standard treatments is often difficult to treat. Recent discoveries are using the body's own immune cells to target B cell markers on cancer cells. Immune cells (called T cells) are collected during a procedure called leukapheresis, and then genetically modified in the laboratory to recognize a protein on cancer cells. The protein it is targeting is CD19, which is commonly found on B cell cancers. Furthermore, the T cells are also tagged with a specific marker, CD34, which allows for purifying the genetically modified T cells and tracking the cells in the blood and tissues. These genetically modified T cells are called CD19-CD34 CAR T-cells (CD19-CD34t). The CD19-CD34t cells, when re-introduced back into the body, may be able to safely and/or effectively attack the cancer cells of patients with CD-19 positive relapsed or refractory NHL, CLL, or SLL.

OUTLINE: This is a dose escalation study of CD19-CD34t metabolically programmed CAR T-cell therapy followed by a dose-expansion study.
Patients undergo leukapheresis over 4-5 hours approximately 1-2 weeks before chemotherapy. Patients then receive cyclophosphamide intravenously (IV) over 30-60 minutes and fludarabine IV over 30-60 minutes on days -5, -4 and -3 and CD19-CD34t metabolically programmed CAR T-cell therapy IV over 30 minutes on day 0 in the absence of disease progression or unacceptable toxicity. Patients with partial remission (PR) or stable disease (SD) with clinical benefit may receive an additional infusion of cells, patients with a CR may receive a second dose if evaluable disease returns. Patients also undergo blood sample collection, positron emission tomography (PET)/computed tomography (CT) scans, or CT scans throughout the study. Patients may also undergo a lymph node biopsy, bone marrow aspiration and biopsy or lumbar puncture throughout the study and may also undergo echocardiography (ECHO) or multigated acquisition scan (MUGA) during screening.
After completion of study treatment, patients are followed up daily for the first 14 days, twice per week until day 28, at 2 and 3 months, every 3 months through year 2, every 6-12 months through year 5, then annually up to year 15.
