GT101 Injection for the Treatment of Metastatic or Recurrent Solid Tumors

Official title

A Single-arm Phase I Clinical Study of GT101 Injection for the Treatment of Metastatic or Recurrent Solid Tumors

Overview

This is a multicenter, single-arm phase I clinical trial.The study process was divided into: screening period, sampling and production period, lymphodepleting chemotherapy period, treatment and observation period, and follow-up period. The study is designed to enroll 20-31 subjects, with 14-20 subjects expected to be evaluable, in an "autologous tumor-infiltrating lymphocyte therapy" regimen that includes： 1. Clear lymphatic pretreatment (FC regimen: cyclophosphamide + fludarabine). 2. GT101 infusion. 3. post-infusion treatment (interleukin-2 intravenous push).
