Trial 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.

About this study
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
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.
Read the 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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing JCAR015 (CD19-targeted CAR T cells) in people with Acute Lymphoblastic Leukemia, run by Juno Therapeutics, a Subsidiary of Celgene at 18 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 4 May 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 18 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 19 Jul 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants With Complete Remission (CR) or Complete Remission With Incomplete Hematopoietic Recovery (CRi), as Determined by an Independent Review Committee (IRC) (time frame: Day 1 (first JCAR015 infusion) up to 12 months after the last JCAR015 infusion). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02535364, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 May 2020.
