About this study
A Study of CD19/BCMA Chimeric Antigen Receptor T Cells Therapy for Patients With Refractory Sjogren's Syndrome
Read the detailed description
Autoimmune diseases only show local pathological damage, but more often systemic lesions. If not diagnosed and treated in time or poorly controlled, a risk of disability or even death as the course of the disease progresses. Studies have shown that B cells can present their own antigens to autoimmune T cells to promote the release of inflammatory factors, or they can differentiate into plasma cells to release autoantibodies, and play an important role in the occurrence and progression of autoimmune diseases. In recent years, it has become a major research focus to deplete B cells in patients or inhibit B cell function. This research focuses on CAR-T cells killing B cells. Sjögren's syndrome (SS) is a systemic autoimmune disease characterized by chronic inflammation of salivary and lachrymal glands, frequently accompanied by systemic symptoms. The presence of various autoantibodies such as rheumatoid factor (RF) and anti-SSA/SSB antibodies, as well as hypergammaglobulinemia, reflect B cell hyperactivity. About five percent of patients with SS develop malignant B cell lymphoma, usually of the mucosa-associated lymphoid tissue (MALT) type and most frequently located in the major salivary glands. This fully reflects the application prospects of CAR-T cells in autoimmune diseases.
Based on the current research progress, our center intends to conduct research on the safety and effectiveness of CD19/BCMA CAR-T cells in the treatment of refractory systemic lupus erythematosus.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Assigned Interventions CD19/BCMA CAR T-cells in people with Sjogren's Syndrome and Autoimmune Diseases, run by Zhejiang University 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 1 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 20 Oct 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 phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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 He Huang, PhD (86-13605714822, hehuangyu@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Dose-limiting toxicity (DLT) (time frame: Baseline up to 28 days after CD19/BCMA CAR T-cells infusion). 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 20 Oct 2021.
