TQB2450 1200 milligrams (mg) administered intravenously (IV) on Day 1 of each 21-day cycle.
TQB2450 is a humanized monoclonal antibody targeting programmed death ligand-1 (PD-L1), which prevents PD-L1 from binding to PD-1 and B7.1 receptors on T cell surface, restores T cell activity, thus enhancing immune response and has potential to treat various types of tumors.
- Objective Response Rate (ORR) [ Time Frame: up to 96 weeks ]Percentage of subjects achieving complete response (CR) and partial response (PR).
- Progression-Free Survival (PFS) [ Time Frame: up to 96 weeks ]PFS defined as the time from randomization until the first documented progressive disease (PD) or death from any cause.
- Duration of Response (DOR) [ Time Frame: up to 96 weeks ]DOR defined as time from earliest date of disease response to earliest date of disease progression based on radiographic assessment.
- Disease Control Rate (DCR) [ Time Frame: up to 24 months ]Percentage of subjects achieving complete response (CR) and partial response (PR) and stable disease (SD).
- Time to Response (TTR) [ Time Frame: up to 24 months ]TTR defined as time from the first dose to the first assessment of PR or CR.
- Overall Survival (OS) [ Time Frame: up to 24 months ]OS defined as the time from randomization to death from any cause. Subjects who do not die at the end of the extended follow-up period, or were lost to follow-up during the study, were censored at the last date they were known to be alive.
