Clinical Trial Summary

Objectives: To evaluate the safety and tolerability of BAT8006 for injection in patients with advanced solid tumors, explore the maximum tolerated dose (MTD), and provide the recommended dose for subsequent clinical trials.

Description:

In this multi-center, open, dose-increasing, dose-expanding Phase I clinical study, rapid titration and a "3+3" dose-increasing design were used to explore the safety, tolerability and PK characteristics of BAT8006 for injection in patients with advanced solid tumors. During the dose-escalation test, appropriate doses were selected for the extended study according to the previous study data.
