What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
αPD1/CTLA4-MSLN-CAR T cellsBiological
BZE2209 is prepared by non-viral vector technology consisting of autologous CD3+T cells expressing mesothelin-specific chimeric antigen receptor (CAR), PD1 nanoantibody and CTLA4 antibody with dimethyl sulfoxide as medium. It can be used for direct intravenous infusion. Autologous CD3+ T cells were transfected with plasmids expressing anti-mesothelin-specific CAR, anti-PD1 nanoantibody and anti-CTLA-4 antibody by electroporation in vitro. Mesothelin-specific CAR is a single-domain antibody (VHH) derived from alpaca, which is composed of a binding domain and a CD28 and CD3ζ chain signal transduction domain.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing αPD1/CTLA4-MSLN-CAR T cells in people with Solid Tumor, run by Shanghai Cell Therapy Group Co.,Ltd 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 16 inclusion and 14 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: looking for participants now, as of the sponsor's last update on 8 Feb 2024. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Yong Xia (021-67091399, xiay@shcell.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: 28 days). 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 Feb 2024.
