PRG-1801 (BCMA-targeting CAR-T Cells)
| Study group | Role | What they receive |
|---|---|---|
| BCMA-targeting CAR T cells therapy | Experimental | The study was divided into two phases: dose exploration phase and dose extension phase. Three dose levels (35×10^6 CAR-T, 100×10^6 CAR-T, 300×10^6 CAR-T) were planned for the dose-exploration phase, and 3 to 6 LN or IgG4-RD subjects were included in each dose group. When 1 out of 3 subjects in a dose group showed DLT, 3 subjects were re-enrolled at that dose level. If DLT occurs in ≥2 of 6 subjects, dose reduction or study termination should be considered.
The safe and effective fixed dose of PRG-1801 was determined through the dose-exploration phase, and after evaluation by the investigators, the dose-expansion phase was conducted, in which an additional 3-6 subjects were included in the safe and effective fixed dose for each of the two indications (Lupus Nephritis and IgG4-Related Disease) to further determine the safety and efficacy of this dose for each indications.

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 Lingli Dong, MD (02783665519, tjhdongll@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safe dose of PRG-1801 infusion (time frame: Up to 24 months after PRG-1801 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?
