Read the detailed description

"This study employed a dose escalation approach combining accelerated titration for the first dose group and the standard '3+3' rule for subsequent dose groups, aiming to minimize patient exposure to ineffective doses while reducing potential risks as much as possible. The study comprised three dose groups for single administration, with doses set at 1×10^7 CAR-NK cells/kg, 2×10^7 CAR-NK cells/kg, and 5×10^7 CAR-NK cells/kg. For the 1×10^7 CAR-NK cells/kg dose group, an accelerated titration method was applied: after obtaining informed consent, one eligible subject meeting the inclusion/exclusion criteria was enrolled into this group. A safety assessment was conducted 14-28 days after the first cell infusion. If no dose-limiting toxicity (DLT) occurred, the subject could proceed to the next dose group upon agreement between the investigator and sponsor. If DLT occurred in one subject, after evaluation by the investigator and sponsor, two additional subjects were enrolled into the same dose group for a 28-day observation period. If DLT events occurred in ≤1 of these three subjects, the study could advance to the next dose group; if DLT events occurred in >1 subject, the decision to continue was made through joint discussion between the investigator and sponsor.

Dose escalation to the 2×10^7 CAR-NK cells/kg dose group followed the standard '3+3' rule. This group initially enrolled three subjects. If no DLT occurred in all three subjects, the study could proceed to the 5×10^7 CAR-NK cells/kg dose group upon agreement between the investigator and sponsor. If one DLT occurred in this group, three additional subjects were enrolled for further observation of the same dose level. If the total number of DLT events among these six subjects was ≤1, the study could advance to the 5×10^7 CAR-NK cells/kg dose group with agreement. If more than one subject experienced DLT in this group, enrollment for this dose level was terminated, and the dose was reduced to complete enrollment of remaining subjects, as decided by the investigator and sponsor.

Dose escalation to the 5×10^7 CAR-NK cells/kg dose group also adhered to the standard '3+3' rule. This group first enrolled three subjects. After cell infusion, a 28-day safety assessment was completed. If no DLT occurred in all three subjects, the decision to continue dose escalation was made through joint discussion between the investigator and sponsor. If no further escalation was decided, the remaining subjects were enrolled in this dose group. If one DLT occurred among the first three subjects, three additional subjects were enrolled for further observation. If DLT events occurred in >1 of these six subjects, enrollment for this dose group was terminated, and the dose level was reduced to complete enrollment of remaining subjects.

If no maximum tolerated dose (MTD) was observed at the maximum dose of 5×10^7 CAR-NK cells/kg, the decision to add additional dose groups was made through joint discussion between the investigator and sponsor, with the new group still following the standard '3+3' rule. During the study, dose groups could be adjusted based on the tolerability, pharmacokinetics, pharmacodynamics, and efficacy of anti-human CD7 CAR-NK cells in patients, combined with prior CAR-NK treatment experience, as determined by the investigator and sponsor. This could involve adding or reducing groups or adjusting dose levels. If special safety or efficacy issues arose during dose escalation, the clinical study could be terminated after joint discussion between the investigator and sponsor.

What is being measured

    Measured: Through study completion, an average of 2 year

Who may be eligible to take part?

The sponsor lists 13 inclusion and 15 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 12 Aug 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?

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 xianmin song, Doctor (18616705298, shongxm@139.com), 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 (time frame: Up to day 28). 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Aug 2025.
