GT101 Injection for the Treatment of Metastatic or Recurrent Solid Tumors

Phase 1

Recruiting

• Conditions: Solid Tumors, Adult
• Interventions: Biological: GT101

• Registration Number: NCT05430373
• Lead Sponsor: Grit Biotechnology

Brief Summary

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).
