Clinical Trial Summary

A multicenter, open phase I clinical study to evaluate the safety, tolerance and pharmacokinetics of BAT8007 for injection in patients with advanced solid tumors.

Description:

This is a multicenter, open, dose increasing and dose expanding Phase I clinical study. About 169~292 patients will be enrolled from research centers in China, the United States, Australia, etc. In the dose increasing stage, accelerated titration and "3+3" dose increasing design were used to explore the safety, tolerance and PK characteristics of BAT8007 for injection in patients with advanced solid tumors. During the dose increasing test, select the appropriate dose according to the previous study data for the extended study.
