About this study
Official title: A Phase I/II Clinical Trial to Evaluate the Safety, Efficacy, and Cellular Kinetics of CT0596 CAR-T Cell Injection in Patients With Relapsed/Refractory Multiple Myeloma
This is a Phase I/II, single-arm, open-label, multicenter clinical trial in patients with relapsed/refractory multiple myeloma (R/R MM). The study aims to evaluate the safety, tolerability, efficacy, cellular kinetics, and immunogenicity of CT0596.
Read the detailed description
Phase I employs a BOIN design for dose escalation to determine the maximum tolerated dose (MTD) and/or recommended Phase II dose (RP2D). Phase II will further confirm the clinical efficacy of CT0596 at the RP2D in R/R MM, with the primary efficacy endpoint being the overall response rate (ORR) at Week 12 post-infusion, assessed by an Independent Review Committee (IRC) per International Myeloma Working Group(IMWG) 2016 criteria.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing CT0596 in people with Relapsed/Refractory Multiple Myeloma, run by UCARsgen Biotech Limited at 2 sites 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 9 inclusion and 19 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 17 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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?
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 Juan Du (021-58752345, juan_du@live.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Phase I:Adverse Events (AE) after CT0596 infusion (time frame: 24months after CT0596 infusion). The study lists 3 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 17 Sep 2026.
