What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CB CAR-NK18.2Biological

    Administered via intravenous infusion on Days 0, 3, and 7.

    Three dose levels are planned:

    Dose Level 1: 2×10^6 cells/kg/infusion Dose Level 2: 8×10^6 cells/kg/infusion Dose Level 3: 16×10^6 cells/kg/infusion

  • CyclophosphamideDrug

    Part of the lymphodepletion regimen. Administered at 500 mg/m^2/day on Days -5 to -3 prior to the first CAR-NK cell infusion.

  • FludarabineDrug

    Part of the lymphodepletion regimen. Administered at 30 mg/m^2/day on Days -5 to -3 prior to the first CAR-NK cell infusion.

Study groupRoleWhat they receive
CB CAR-NK182 Dose EscalationExperimentalParticipants will receive a lymphodepleting conditioning regimen (FC regimen) followed by three intravenous infusions of Claudin18.2-targeted umbilical cord blood-derived CAR-NK cells (CB CAR-NK182) on days 0, 3, and 7. The study follows a "3+3" dose-escalation design with three planned dose levels. Three dose levels: Dose Level 1 (2×10⁶ cells/kg/infusion on days 0, 3, and 7), Dose Level 2 (8×10⁶ cells/kg/infusion on days 0, 3, and 7), Dose Level 3 (16×10⁶ cells/kg/infusion on days 0, 3, and 7). 3-6 subjects will be enrolled per dose level. Each subject will be observed for at least 28 days after the first infusion, with a long-term follow-up period of 2 years post-first infusion. Standard "3+3" rules apply for DLT observation and dose escalation decisions.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CB CAR-NK18.2, Cyclophosphamide and Fludarabine in people with Gastric Cancer and Pancreas Adenocarcinoma, run by Zhejiang Provincial People's Hospital 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 9 inclusion and 12 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: finished, as of the sponsor's last update on 9 Jul 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

MTD (time frame: 1 month). 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?

On the ClinicalTrials.gov record for NCT06464965, which also lists 10 linked publications.

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 9 Jul 2026; AzTrials last refreshed its copy on 8 Nov 2026.
