About this study

Official title: Humanized CAR-T Therapy for Treatment of Recurrent or Refractory B Cell Malignancy by Targeting CD19

The present study evaluates the safety and efficacy of humanized Chimeric antigen receptor T cells (CAR-T) in treating recurrent or refractory B cell malignancy targeting CD19 with a humanized scFv. All participants will receive autologous chimeric antigen receptor engineered T cells.

Read the detailed description

CD19 has been extensively evaluated as a therapeutic target for recurrent or refractory B cell malignancy by chimeric antigen receptor T cell therapy, the single chain antibody sequence (scFv) against CD19 derived from a mouse hybridoma was widely employed. However, the immunogenicity of the mouse scFv sequence might be one of the reasons that CAR-T cells cannot persist in vivo for long. In present study investigators replace the mouse-derived scFv with a a humanized one and evaluate its safety and efficacy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CAR-TBiological

    Patients will be infused with autologous CAR-T infusion in a dose escalating manner.

Study groupRoleWhat they receive
CAR-TExperimentalIn interventional studies, patients enrolled will receive autologous 2nd generation CAR-T cells, which contain a humanized single chain antibody sequence against CD19.
Receives: Biological: CAR-T

What is being measured

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

  1. CAR-T cells persistence in peripheral blood

    The presence of CAR T cells in patients' peripheral blood will be quantified with real time qPCR

    Measured: 12 months

Secondary outcomes (1)
  1. B cell number and immunoglobulins in peripheral blood

    The number of B cells and immunoglobulins in peripheral blood will be evaluated by routine methods

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing CAR-T in people with Leukemia, Lymphocytic, Chronic, B-Cell, run by Kai Lin Xu; Jun Nian Zheng at 2 sites 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 11 inclusion and 9 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 4 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 combined 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.

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?

Results are not available in the source record.

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

Contact Jiang Cao, M.D., Ph.D. (8651685802291, zimu05067@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

CAR-T cells persistence in peripheral blood (time frame: 12 months). 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 NCT02782351, 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 Aug 2017.
