About this study
Official title: CD19/CD20 Dual-CAR-T for Patients With B-cell Leukemia
This is a single center, single arm, open-label, phase I study to evaluate the safety and efficacy of CD19/CD20 Dual-CAR-T cells in patients with refractory and relapsed B-cell leukemia.
Read the detailed description
This Phase I study is designed as a pilot trial evaluating the safety and efficacy of CD19/CD20 Dual-CAR-T cell therapy in subjects with refractory and relapsed B cell leukemia. Subjects will receive cytoreductive chemotherapy with cyclophosphamide and fludarabine on days -5, -4 and -3 followed by infusion of CD19/CD20 Dual-CAR-T cells. Safety and efficacy of CD19/CD20 Dual-CAR-T cells therapy will be monitored. The purpose of current study is to determine the clinical efficacy and safety of CD19/CD20 Dual-CAR-T cells therapy in patients with refractory and relapsed B-cell leukemia.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing CD19/CD20 Dual-CAR-T cells in people with B-cell Leukemia, run by Hebei Yanda Ludaopei 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 11 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: finished, as of the sponsor's last update on 8 Mar 2022. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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 adverse events. (time frame: 6 months). The study lists 2 primary outcomes in all. 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 8 Mar 2022.
