Brief Summary:
This single-arm, multicenter Phase 2 trial will treat adult patients who have relapsed or refractory B-ALL with an infusion of the patient's own T cells that have been genetically modified to express a chimeric antigen receptor (CAR) that will bind to leukemia cells that express the CD19 protein on the cell surface. The study will determine if these modified T cells (called JCAR015) help the body's immune system eliminate leukemia cells. The trial will also study the safety of treatment with JCAR015, how long JCAR015 cells stay in the patient's body, the extent to which JCAR015 eliminates minimal residual disease, and the impact of this treatment on survival.

Condition or disease Intervention/treatment Phase
Acute Lymphoblastic Leukemia Biological: JCAR015 (CD19-targeted CAR T cells) Phase 2

Detailed Description:
This is a single-arm, multicenter Phase 2 study to determine the efficacy and safety of JCAR015 in adult patients with relapsed or refractory B-ALL. The study will have the following sequential phases: Part A (screening, leukapheresis, cell product preparation, and cytoreductive chemotherapy) and Part B (treatment and follow-up). The follow-up period for each participant is approximately 12 months after the final JCAR015 infusion. The total duration of the study is expected to be approximately 3 years. Long-term follow-up for survival, toxicity, and viral vector safety will continue under a separate long-term follow-up protocol per health regulatory authority guidelines, currently up to 15 years after the last JCAR015 infusion.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 82 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 2, Single-arm, Multicenter Trial to Determine the Efficacy and Safety of JCAR015 in Adult Subjects With Relapsed or Refractory B-Cell Acute Lymphoblastic Leukemia
Actual Study Start Date : August 21, 2015
Actual Primary Completion Date : April 26, 2017
Estimated Study Completion Date : October 2017

Arm Intervention/treatment
Experimental: JCAR015
JCAR015 will be administered as two intravenous (IV) infusions.
Biological: JCAR015 (CD19-targeted CAR T cells)

Part A: Following leukapheresis and concurrent with generation of JCAR015, participants will receive, at the Investigator's discretion, cytoreductive chemotherapy based on the Investigator's choice of regimens and/or supportive care.

Part B: Participants who are eligible for treatment in Part B will receive two IV doses of JCAR015 CAR T cells. JCAR015 infusion will be preceded by lymphodepleting chemotherapy.

Primary Outcome Measures :
  1. Overall remission rate (ORR) [ Time Frame: After 50 efficacy-evaluable subjects have received JCAR015 infusion and completed 6 months from first JCAR015 infusion or discontinued earlier ]
    Efficacy of JCAR015 therapy -- ORR, which includes complete remission (CR) and complete remission with incomplete hematopoietic recovery (CRi), as determined by assessments of bone marrow, peripheral blood, physical exam, and cerebrospinal fluid (CSF). The primary endpoint will be based on independent review committee (IRC) assessment.

Secondary Outcome Measures :
  1. Duration of remission (DOR) [ Time Frame: 12 months ]
  2. Percentage of patients who achieve CR or CRi with no evidence of minimal residual disease (MRD) in the bone marrow [ Time Frame: 12 months ]
  3. Treatment-related adverse events as assessed by CTCAE v4.03 [ Time Frame: 12 months ]
  4. Relapse-free survival [ Time Frame: 12 months ]
  5. Event-free survival [ Time Frame: 12 months ]
  6. Overall survival [ Time Frame: 12 months ]
  7. ORR at Month 6 following the final JCAR015 infusion [ Time Frame: 6 months ]
  8. Percentage of patients who achieve a morphologic remission within 6 months after the final JCAR015 infusion and then proceed to hematopoietic stem cell transplant (HSCT) [ Time Frame: 12 months ]
  9. Maximum concentration of JCAR015 (Cmax) in the peripheral blood and bone marrow [ Time Frame: 12 months ]
  10. Time to maximum concentration of JCAR015 (Tmax) in the peripheral blood and bone marrow [ Time Frame: 12 months ]
  11. Area under the concentration-vs-time curve (AUC) in the peripheral blood and bone marrow [ Time Frame: 12 months ]
  12. Profile of soluble immune factors that may be generated in response to JCAR015 administration [ Time Frame: 12 months ]
