Study groupRoleWhat they receive
CD19-CAR-T2 T CellsExperimentalThe subject's T cells will be modified to those which could identify and kill the tumor cells (CD19+ cells). These CD19-CAR-T2 T cells will be infused over 10-15 minutes on days Day 1, 2 and 3 tentatively according to the response to infusion.
Receives: Biological: CD19-CAR-T2 Cells

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The maximum tolerated dose(MTD) of CD19 positive relapsed/ refractory acute leukimia treated wtih CD19-CAR-T2 cells

    Measured: 24 weeks

Secondary outcomes (2)
  1. Number of Participants With Abnormal Laboratory Values and/or Adverse Events That Are Related to Treatment

    Adverse events and laboratory abnormalities (type, frequency and severity)

    Measured: 12 months

  2. Overall Response Rate

    Overall Response Rate (ORR), which includes Complete Remission (CR) and Complete Remission with Incomplete Blood Count Recovery (CRi), as determined by assessments of peripheral blood, bone marrow, CNS symptoms, physical exam (PE) and CSF. The primary endpoint will be based on the IRC assessment. The local investigator's assessed results will be used for sensitivity analysis.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CD19-CAR-T2 Cells in people with Acute Leukemia, run by Guangdong Provincial People's Hospital at 1 site in China.

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 8 inclusion and 18 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: status not confirmed, as of the sponsor's last update on 11 Sep 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Xin Du, Dr. (+86 20 83827812 ext. 62122, miyadu@hotmial.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The maximum tolerated dose(MTD) of CD19 positive relapsed/ refractory acute leukimia treated wtih CD19-CAR-T2 cells (time frame: 24 weeks). 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 NCT02822326, which also lists 13 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 11 Sep 2017.
