Clinical Trial Summary

Objectives:To evaluate the safety and tolerability of BAT8008 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 BAT8008 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Presence of ADA/nentralizing antibodies(NAbs)	presence of anti-drug antibody/ nentralizing antibodies	91 days after first dose of BAT8008
Primary	Dose limiting toxicity (DLT)	DLT was defined as grade 3 or higher toxicity associated with the investigational product that occurred within 21 days of the subject's initial administration	At the end of Cycle 1( first cycle is 21 days, subsequent cycles are 14 days)
Primary	Maximum tolerated dose (MTD)	MTD was defined as exploration in a dose group observed =1/6 of subjects during the DLT evaluation period to the highest dose level of DLT.	At the end of Cycle 1( first cycle is 21 days, subsequent cycles are 14 days)
Secondary	AUC(0-inf)after cycle 6 administration	The area under the concentration-time curve extrapolated from time 0 to infinity	91 days after first dose of BAT8008
