About this study
CD19 CAR-T has been widely developed in patients with R/R ALL and has also been generally recognized by the industry. In 2017, the U.S. FDA approved Novartis's CD 19 CAR-T product Kymriah for the treatment of R/R ALL. However, these CAR-T cells are constructed from patients' autologous T cells, and the production and preparation time is long; on the other hand, most patients have received multiple chemotherapy before CAR-T treatment, and the quantity and quality of T cells often cannot meet the needs of clinical treatment. It is also an important factor leading to the failure of CAR-T cell therapy, which limits the large-scale clinical application of CAR-T.
T cells derived from healthy donors are not only sufficient in quantity and quality guaranteed, but also available at any time. In December 2020, lancet reported a clinical study of 19 patients receiving allogeneic CAR-T cell ALL. 14 patients were evaluated as CR/CRi (67%) 28 days after treatment, and the median sustained remission time was 4.1 moon. Allogeneic CAR-T cells are safe and effective for the treatment of ALL, and their clinical application range is expected to improve the remission rate and survival rate of patients with R/R ALL.
Read the detailed description
Chimeric antigen receptor (CAR) T cells enable T cells to recognize and kill tumor cells that express specific antigens through genetic engineering. CD19 is expressed on the membrane surface of pre-B cells and mature B cells, but not on the surface of T cells and normal granulocytes. It is an ideal therapeutic target for B cell-derived tumors. A large number of previous studies have confirmed that CD19 CAR-T cells are a safe and effective method for the treatment of ALL. In 2018, New England Journal published the long-term follow-up data of CD19 CAR-T for relapse/refractory (R/R) ALL, 53 patients with r/r ALL who received a single infusion of CD19 CAR-T The response efficiency (CR+PR) reached 98%, of which about 83% of CR patients, with a median survival time of 12.9 months; greatly improved the remission rate and survival rate of r/r ALL patients.
Nowadays,CD19 CAR-T has been widely developed in patients with R/R ALL and has also been generally recognized by the industry. In 2017, the U.S. FDA approved Novartis's CD CAR-T product Kymriah for the treatment of R/R ALL. However, these CAR-T cells are constructed from patients' autologous T cells, and the production and preparation time is long; on the other hand, most patients have received multiple chemotherapy before CAR-T treatment, and the quantity and quality of T cells often cannot meet the needs of clinical treatment. It is also an important factor leading to the failure of CAR-T cell therapy, which limits the large-scale clinical application of CAR-T.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Allogeneic CD19 CAR-T cells in people with Relapse Leukemia and Refractory Leukemia, run by Shenzhen University General 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 12 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 20 Dec 2021. 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?
Contact Li Yu (+8675521839178, liyu@vip.163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
CRR (time frame: From data of enrollment until the first documented progression of disease, up to 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 20 Dec 2021.
