About this study

Official title: a Clinical Research of Sequential CAR-T Bridging Hematopoietic Stem Cell Transplantation in the Treatment of Relapse/Refractory B-cell Malignancies

The main purpose of this study is to explore the sequential therapeutic effect and evaluate the safety of anti-CD19 or anti-CD20 CAR-T cells briging HSCT in the treatment of relapse/refractory B cell malignancies.

Read the detailed description

The CD19-targeted CAR-T has shown exellent therapeutic efficiency in B cell malignancies,especially in acute lymphocytic leukemia. Recently the anti-CD20 CAR T cells has been used in the treatment of relapsed/refractory DLBCL and exhibited good clinical outcomes.

However, patients treated with CAR-T may face relapse of CD19 or CD20 mutation. Therefore we attempt to maintain and relieve patients by sequential therapy of the HSCT 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.

  • CD19 or CD20 CAR T cells briging HSCTBiological

    Patients will receive a one-week regimen of chemotherapy consisting of fluid arabise and cyclophosphamide aimed to deplete the lymphocytes. One week later, patients are intravenously infused autologous anti-CD19 or anti-CD20 CAR T cells.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CD19 or CD20 CAR T cells briging HSCT in people with Lymphoma, Large B-Cell, Diffuse and Leukemia, Lymphocytic, Chronic, B-Cell, 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 14 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 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?

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?

Overall survival rate of patients treated with anti-CD19 or anti-CD20 CAR T cells (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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.
