What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
KSV01 InjectionDrug
KSV01 Injection is one kind of third-generation non-replicative self-inactivating lentivirus vector which carries CD19 CAR.
| Study group | Role | What they receive |
|---|---|---|
| KSV01 Injection | Experimental | KSV01 Injection is one kind of third-generation non-replicative self-inactivating lentivirus vector which carries CD19 CAR. Receives: Drug: KSV01 Injection |
What is being measured
The primary outcome is the main question the study is designed to answer.
Dose-limiting Toxicity
DLT evaluation period: The DLT evaluation period is defined as within 28 days (inclusive) after the subjects' first administration of KSV01 injection during the dose escalation stage. All adverse events should be graded and evaluated in accordance with CTCAE v5.0. Among them, cytokine release syndrome (CRS) and immune effector cell-related neurotoxicity syndrome (ICANS) should be determined and graded in accordance with the standards of the American Society for Transplantation and Cell Therapy (ASTCT).
Measured: 28 days after administration

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing KSV01 Injection in people with Non-Hodgkin Lymphoma and Diffuse Large B Cell Lymphoma (DLBCL), run by TCRx Therapeutics 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 10 inclusion and 21 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 26 Oct 2026. 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?
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.
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?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Dose-limiting Toxicity (time frame: 28 days after administration). 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 26 Oct 2026; AzTrials last refreshed its copy on 6 Nov 2026.
