NCT04385641

Brief Summary

This study is an open, single infusion, cell infusion dose /method exploration study. In patients with gastric cancer and gastroesophageal cancer without effective treatment, the safety of UCB-NK cell immunotherapy was evaluated and the preliminary curative effect results were obtained.

Outcome Measures

Primary Outcomes (3)

  • Safety assessment

    Evaluation of adverse events and severity according to CTCAE v5.0

    4 weeks

  • Hematology toxicity

    After 7 days of treatment, the ≥ 4 degree hematotoxicity (excluding lymphocyte reduction) related to UCB-NK treatment could not recover to ≤ 3 degree

    7 days

  • Non hematologic toxicity

    Any non hematologic toxic reaction≥4 degree related to UCB-NK treatment cannot be reduced to≤3 degree within 3 days and no further improvement is found; Gastric mucosal injury including gastric hemorrhage≥3 degree related to UCB-NK treatment; Other non hematologic toxicity≥3 degree related to UCB-NK treatment lasted for more than 7 days.

    7 days

Secondary Outcomes (1)

  • Tumor assessment

    4 years

Study Arms (2)

Dose-finding (Group A)

EXPERIMENTAL

In this study, the dose was explored according to the "3+3" mode, in which group A was divided into three dose groups: 1.5\*10^9 group, 2\*10^9 group and 3\*10^9 group. If DLT occurs in one of the first three subjects in each dose group within four weeks after cell infusion, three subjects will continue to be included. If more than 1/6 cases of DLT appear in 6 subjects with 1.5\*10^9 dose, the dose level and/or cell infusion frequency and method will be reduced after discussion between the investigator, the collaborator and DMC. If DLT did not occur in the first 3 subjects within 4 weeks after receiving 1.5\*10^9 cell infusion,another three subjects were enrolled into the group received 2\*10^9 cell infusion. DLT did not occur within 4 weeks after cell infusion, it will increase to 3\*10^9 dose group. That is to say, the first three subjects were included for observation for 4 weeks in the 3\*10^9 dose group, if DLT did not occur, there will be another 3 cases, reaching to 6 subjects.

Other: Cell infusion for Dose-finding (Group A)

Extended research (Group B)

EXPERIMENTAL

If DLT≤1/6, the dose will not be increased. This dose will also be used as the treatment dose of group B. If DLT is more than 1/6 in the 3\*10^9 dose group, three subjects will be added in 2\*10^9 dose group. If DLT ≤1/6 in 4-week observation, the 2\*10^9 will be the maximum tolerable dose, and will be used as the treatment dose of group B. The subjects in group A were enrolled first, after at least 4 weeks of observation for all subjects, six subjects will be included in group B.

Other: Cell infusion for Extended research (Group B)

Interventions

Group A:HLA-I and HLA-II molecular typing were performed at the serological and molecular levels, and the HLA-I and HLA-II molecular antigens of donor and subjects match on 3, 4, 5 or 6 / 6. After the successful matching, the non myeloablative immunosuppressive pretreatment with cyclophosphamide (900 mg / m^2 / day) and fludarabine (30 mg / m^2 / day) will be performed 6, 5, 4 and 3 days before the infusion of UCB-NK cells. After the pretreatment, the cell infusion was started on day 0, and the cell infusion could be divided into 50% and 50% for two consecutive days or every other day. To ensure clinical safety, if treatment-related adverse events reach DLT after the first infusion, the cell infusion will stop.

Dose-finding (Group A)

Group B:Non myeloablative immunosuppressive pretreatment and cell transfusion were the same as group A.

Extended research (Group B)
