CART-19 Immunotherapy in Mantle Cell Lymphoma

Patients receive anti-CD19-CAR (coupled with CD137 and CD3 zeta signalling domains)vector-transduced autologous T cells over a period of 4 or 5 consecutive days in an escalating dose. After completion of study treatment, patients are followed intensively for 6 months, every 3 months for 2 years, and annually thereafter for 10 years.

PRIMARY OBJECTIVES: I. Determine the safety and efficacy of the chimeric antigen receptor T cells transduced with the anti-CD19 (cluster of differentiation antigen 19 ) vector (referred to as CART-19 cells) in elderly patients with MCL. II. Determine duration of in vivo survival of CART-19 cells. RT-PCR (reverse transcription polymerase chain reaction) analysis of whole blood will be used to detect and quantify survival of CART-19 TCR (T-cell receptor) zeta:CD137 and TCR zeta cells over time. SECONDARY OBJECTIVES: For patients with detectable disease, measure anti-tumor response due to CART-19 cell infusions. Estimate relative trafficking of CART-19 cells to tumor in bone marrow and lymph nodes. Determine if cellular or humoral host immunity develops against the murine anti-CD19, and assess correlation with loss of detectable CART-19 (loss of engraftment).
