Phase 1 |
Detailed Description
This is a multi-center, open, dose-increased and dose-expanded phase I clinical study. About 18-42 patients will be recruited from research centers in China. In the stage of dose increase, the safety, tolerance, pharmacokinetics and preliminary clinical efficacy of BAT7104 injection in patients with advanced malignant tumors were investigated by using accelerated titration and "3+3" dose increase design. During the dose increase test, the appropriate dose was selected according to the previous study data of the extended study.
