Clinical Trial Summary

This is a Pilot/Phase I, single arm, single center, open label study to determine the safety, efficacy and cellular kinetics of CART19 (CTL019) in chemotherapy resistant or refractory CD19+ leukemia and lymphoma subjects. The study consists of three Phases: 1) a Screening Phase, followed by 2) an Intervention/Treatment Phase consisting of apheresis, lymphodepleting chemotherapy (determined by the Investigator and based on subject's disease burden and histology, as well as on the prior chemotherapy history received), infusions of CTL019, tumor collection by bone marrow aspiration or lymph node biopsy (optional, depending on availability), and 3) a Follow-up Phase. The suitability of subjects' T cells for CTL019 manufacturing was determined at study entry. Subjects with adequate T cells were leukapheresed to obtain large numbers of peripheral blood mononuclear cells for CTL019 manufacturing. The T cells were purified from the peripheral blood mononuclear cells, transduced with TCR-ζ/4-1BB lentiviral vector, expanded in vitro and then frozen for future administration. The number of subjects who had inadequate T cell collections, expansion or manufacturing compared to the number of subjects who had T cells successfully manufactured is a primary measure of feasibility of this study. Unless contraindicated and medically not advisable based on previous chemotherapy, subjects were given conditioning chemotherapy prior to CTL019 infusion. The chemotherapy was completed 1 to 4 days before the planned infusion of the first dose of CTL019. Up to 20 evaluable subjects with CD19+ leukemia or lymphoma were planned to be dosed with CTL019. A single dose of CTL019 (consisting of approximately 5x10^9 total cells, with a minimal acceptable dose for infusion of 1.5x10^7 CTL019 cells) was to be given to subjects as fractions (10%, 30% and 60% of the total dose) on Day 0, 1 and 2. A second 100% dose of CTL019 was initially permitted to be given on Day 11 to 14 to subjects, providing they had adequate tolerance to the first dose and sufficient CTL019 was manufactured.

Description:

Primary objectives: 1. To evaluate the safety and feasibility of a single target dose of 5 times 10e9 total cells, acceptable range of 1.5 times 10e7 to 5 times 10e9 total cells comprised of autologous CART-19 cells that express the TCR zeta and 4-1 BB costimulatory domain. Secondary objectives: 1. Proof of mechanism: determine if 2nd generation CAR expressing 4-1BB costimulation domains have improved persistence in patients. 2. Proof of concept: determine the effects of CART-19 on CD19 expression in vivo. 3. Proof of bioactivity: Evaluate changes in systemic soluble immune factors in patients 4. Proof of bioactivity: Evaluate impact of CART19 treatment on tumor burden 5. Explore whether CART-19 cells retain anti-tumor activity in vivo. 6. Determine if host immunity develops against CART-19. 7. Characterize the relative subsets of CART-19 T cells (Tcm, Tem, and Treg). 8. Describe survival and response rates

Secondary	Overall Response Summary	Efficacy assessments for ALL were performed based on bone marrow and blood morphologic criteria and physical examination findings. The definitions for response are primarily based on the standardized response criteria defined by National Comprehensive Cancer Network (NCCN) Guidelines (NCCN, 2013 v.1).; Efficacy assessments for CLL were based on lymphadenopathy, hepatomegaly, splenomegaly, bone marrow and blood morphologic and laboratory assessments. The response criteria are consistent with NCCN Guidelines Version 2.2012 CLL/SLL, which is based on the 2008 International Workshop Group on CLL (IWCLL) revisions of the original guidelines for evaluating disease response released in 1996 by the National Cancer Institute Working Group (NCI/WG).	5 years
