What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
RJMty19 (CD19-CAR-DNT cells)Biological
Lentiviral vector-transducted double negative T cells (DNT) to express anti-CD19 CAR. Prior to cellular infusion, each patient received cyclophosphamide, fludarabine and Etoposide lymphodepleting chemotherapy.
| Study group | Role | What they receive |
|---|---|---|
| RJMty19 (CD19-CAR-DNT Cells) | Experimental | The trial is divided into two parts: Part A is a dose escalation trial with four dose groups (5×10^6 CAR+ cells/kg, 1×10^7 CAR+ cells/kg, 2×10^7 CAR+ cells/kg and 4×10^7 CAR+ cells/kg at day 0), with 8-24 patients planned to be enrolled. Part B is a dose-expansion trial in which 3~6 patients will receive RJMty19 infusions at RP2D dose levels. Receives: Biological: RJMty19 (CD19-CAR-DNT cells) |

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing RJMty19 (CD19-CAR-DNT cells) in people with B-cell Non-Hodgkin's Lymphoma, run by Guangdong Ruishun Biotech Co., Ltd.
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 38 inclusion and 16 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: opening soon, as of the sponsor's last update on 18 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.
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?
Contact Weili Zhao, MD,PhD (+862164370045 ext. 610707, zhao.weili@yahoo.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: Up to 28 days). 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 18 Mar 2024; AzTrials last refreshed its copy on 8 Nov 2026.
