Genetically Engineered Cells (Autologous Anti-CD7-CAR-CD28zeta T-cells) for the Treatment of Recurrent T-cell Malignancies
This phase I trial tests the safety, side effects, and best dose of autologous anti-CD7-CAR-CD28zeta T-cells in treating patients with T-cell malignancies that have come back (recurrent). Antibodies are types of proteins that protect the body from bacterial and other diseases. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells including tumor cells. The T cells given in this study will come from the patient and will have a new gene put in them that makes them able to recognize CD7, a protein on the surface of cancer cells. These CD7-specific T cells may help the body's immune system identify and kill CD7 positive cancer cells. The T lymphocytes will also contain CD28, which stimulates T cells and makes them last longer. Giving autologous anti-CD7-CAR-CD28zeta T-cells may help treat patients with recurrent or refractory T cell malignancies.

PRIMARY OBJECTIVE:
I. To evaluate the safety of escalating doses of autologous peripheral blood T lymphocytes (ATLs) genetically modified to express chimeric antigen receptors (CAR) targeting the CD7 molecule (CD7.CAR) in combination with lymphodepletion in patients with relapsed/refractory T-cell malignancies.
SECONDARY OBJECTIVE:
I. To measure the anti-tumor effects of CD7.CAR-ATLs in patients with T-cell leukemia or lymphoma.
EXPLORATORY OBJECTIVES:
I. To measure the survival and function of CD7.CAR-ATLs in vivo.
II. To evaluate whether elimination of T cell leukemia or lymphoma by CD7 CAR T cells will allow patients previously ineligible for hematopoietic stem cell transplantation (HSCT) due to residual disease to proceed to curative allogeneic HSCT.
OUTLINE: This is a dose-escalation study.
LYMPHODEPLETION: Patients receive cyclophosphamide intravenously (IV) over 1 hour and fludarabine IV over 30 minutes per institutional guidelines.
Beginning 24 hours after completion of lymphodepletion, patients receive autologous anti-CD7-CAR-CD28zeta T-cells IV over 1-10 minutes.
After completion of study treatment, patients are followed up at 3, 6, 9, and 12 months, every 6 months for 4 years, and then annually for up to 15 years.
