  • Gender is not limited, age from 14 years to 75 years.
  • Patients must have measurable or evaluable disease at the time of enrollment, which may include any evidence of disease including minimal residual disease detected by flow cytometry, cytogenetics, or polymerase chain reaction (PCR) analysis.
  • Patients are expected to survive for more than 3 months by their physicians at the time of enrollment.

About this study

The main purpose of this study is to explore the sequential therapeutic effect of CD19-targeted and CD20-targeted chimeric antigen receptor T(CAR-T) cells in the treatment of Diffuse Large B Cell Lymphoma(DLBCL)

Read the detailed description

The anti-CD20 antibody has been broadly used in the treatment of B cell malignancies and exhibited good clinical outcomes. The CD19-targeted CAR-T has shown excellent therapeutic efficiency in B cell malignancies,especially in acute lymphocytic leukemia. However, patients treated with CD19-targeted CAR-T may face relapse of CD19 mutation. Therefore we attempt to treat Diffuse Large B Cell Lymphoma(DLBCL) patients by sequential therapy of the 2 targets and hope to combine their advantages.

What participants receive

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

  • Anti-CD19 CAR-T cells and Anti-CD20 CAR-T cellsBiological

    Also called CD19-targeted CAR-T cells and CD20-targeted CAR-T cells

    Patients receive autologous-derived CD19-targeted CAR-T cells following CD20-targeted CAR-T cells after receiving lymphodepleting chemotherapy.

Study groupRoleWhat they receive
Diffuse Large B Cell Lymphoma(DLBCL)ExperimentalThe trial will be conducted in a manner of simon two-stage design with Anti-CD19 CAR-T cells and Anti-CD20 CAR-T cells, beginning in the first stage with the aim of over 30% reaction rate among 15 patients with Diffuse Large B Cell Lymphoma(DLBCL). Only when the expected reaction rate is achieved the 30 patients left can be recruited.
Receives: Biological: Anti-CD19 CAR-T cells and Anti-CD20 CAR-T cells

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Anti-CD19 CAR-T cells and Anti-CD20 CAR-T cells in people with Lymphoma, Large B-Cell, Diffuse, run by Southwest Hospital, China 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 15 inclusion and 13 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 7 Sep 2016. 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 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?

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?

Adverse Events That Are Related to Treatment (time frame: 2 years). 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 NCT02737085, which also lists 1 linked publication.

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 7 Sep 2016.
