BGT007 Treatment for Recurrent/refractory Gastrointestinal Malignancies

Официальное название

Exploratory Clinical Study Initiated by Researchers on the Safety and Preliminary Efficacy of BGT007 in Treating Patients with Recurrent/refractory Gastrointestinal Malignancies

Обзор

This study is an exploratory research on single arm, open, and improved "3+3" dose escalation. BGT007 will explore two dose groups, namely (Group A: 3.0X10 \^ 8 3 cases, Group B: 6.0X10 \^ 8 3 cases), and receive the same dose infusion after observing lower adverse reactions and initial benefits (SD or PR), with an interval of one month. Each subject can receive a maximum of 3 infusions in total.

Подробное описание

Main research objectives:

Evaluate the safety and tolerability of BGT007 in treating patients with recurrent/refractory multiple gastrointestinal malignancies;

Secondary research objective:

1. Evaluate the pharmacokinetic (PK) characteristics of BGT007; 2. Evaluate the preliminary effectiveness of BGT007 product.
