Clinical Trial Summary

This is a single-arm, open label, multi-center Phase 1 clinical study to evaluate the safety and efficacy of autologous memory lymphocyte therapy (NewishT) in patients with hepatocellular carcinoma at high risk of recurrence after radical resection.

Description:

This study is divided into two dose groups and two phases. Phase Ia climbed from low-dose group to high-dose group in turn according to the 3+3 dose escalation principle. Phase Ib extended 10 subjects each group.

After the completion of treatment, the subjects shall continue to receive safety follow-up until 14 days after the last administration, and all adverse events shall revert to level I or all adverse events shall be clinically stable (whichever is later achieved); Tumor imaging assessment was performed at week 7 and week 20 to observe the progression of disease.

After week 20, the survival follow-up period was entered, and patients were followed up until death, loss of follow-up, or trial termination, whichever occurred first. Survival was followed up by telephone every 12 weeks (±7 days), and radiographic evidence should be obtained if recurrence/progression occurred.
