About this study
To study the safety and effectiveness of cord blood-derived CAR-NK cells targeting CD19 in patients with B-cell non-Hodgkin's lymphoma
Read the detailed description
This is an open, single-arm, single-dose, dose-escalation clinical trial designed to evaluate the safety and the preliminary efficacy of CB CAR-NK019 cells. 9-18 patients are planned to be enrolled in the dose-escalation trial (2×10^6 cells/kg ,3×10^6 cells/kg, 4×10^6 cells/kg) . The primary endpoints are DLT, MTD, and the second endpionts are the overall response rates (CR and PR), overall survival, and progression-free survival. Based on the results in the dose-escalation trial, the recommended dose will be determined. Another 30 patients will be enrolled to estimate the safety and efficacy of CB CAR-NK019 under the best dose.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing anti-CD19 CAR-NK in people with B-cell Non Hodgkin Lymphoma, run by Second Affiliated Hospital, Zhejiang University, School of Medicine 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 5 inclusion and 3 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 4 Mar 2025. 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?
Contact Wenbin Qian (+8613605801032, qianwb@zju.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of dose limiting toxicity (DLTs) (time frame: Up to 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 4 Mar 2025.
