Gastrointestinal Tumors Clinical Trial
Official title:
Clinical Study on the Safety and Preliminary Efficacy of BGT007H Cell Therapy in Patients With Recurrent/Refractory Gastrointestinal Tumors
This study is an exploratory single-arm, open, modified "3+3" dose escalation study with BGT007H injection. Approximately 11 to 14 subjects with recurrent/refractory gastrointestinal tumors will be enrolled to evaluate the safety of BGT007H injection. Four dose levels were designed for this study: 1.0×10^8cells, 3.0×10^8cells, 1.0×10^9cells, and 3.0×10^9cells. The primary objective of this study was to evaluate the safety, tolerability and pharmacokinetic profile of BGT007H cell therapy in patients with recurrent/refractory digestive tract tumors, to determine the maximum tolerated dose or the best effective dose, and to initially evaluate the effectiveness of BGT007H cell products.
Main research objectives: Evaluation of the safety and tolerability of BGT007H cell therapy in patients with recurrent/refractory gastrointestinal tumors Secondary research objectives: 1. Evaluate the pharmacokinetic (PK) characteristics of BGT007H cells after reinfusion; 2. Evaluation of the initial effectiveness of BGT007H cell therapy in patients with recurrent/refractory gastrointestinal tumors Exploratory Purpose 1. Exploring the correlation between the proliferation and survival of BGT007H cells in vivo and their therapeutic effects; 2. Exploring the correlation between target expression levels and efficacy ;
