Outcome

Type Measure Description Time frame Safety issue
Primary Safety endpoint: number of subjects with adverse events (AE) An AE is any untoward medical occurrence in a subject, temporally associated with the use of study treatment, whether or not considered related to the study treatment. Up to approximately 2 years
Primary Primary efficacy endpoint: objective response rate (ORR) ORR is the proportion of subjects with complete response(CR) or partial response(PR) assessed according to RECIST v1.1 Up to approximately 2 years
Secondary Efficacy Endpoint assessed according to RECIST v1.1 : disease control rate (DCR) DCR based on RECIST v1.1. DCR is defined as the proportion of subjects with CR, PR, or SD. Up to approximately 2 years
Secondary Efficacy Endpoint assessed according to RECIST v1.1 : progression-free survival (PFS) PFS based on RECIST v1.1. PFS is defined as the time from the date of randomization till the first documentation of disease progression assessed by the investigator or death due to any cause (whichever occurs first) Up to approximately 2 years
Secondary Efficacy Endpoint assessed according to RECIST v1.1 : Overall survival (OS) OS based on RECIST v1.1. OS is defined as the time from the date of randomization or first dosing date to death due to any cause Up to approximately 2 years
Secondary Serum PK concentrations of AK112 Serum PK concentrations of AK112 in individual subjects at different time points after AK112 administration Up to approximately 2 years
Secondary To evaluate the immunogenicity of AK112: Number of subjects with anti-drug antibodies (ADA) Immunogenicity of AK112: Number of subjects with detectable anti-drug antibodies (ADA) Up to approximately 2 years
Secondary To evaluate the immunogenicity of AK112: Percentage of subjects with anti-drug antibodies (ADA) Immunogenicity of AK112: Percentage of subjects with detectable anti-drug antibodies (ADA) Up to approximately 2 years
Secondary To evaluate the correlation between the expression of PD-L1 and the antitumor activity of AK112 in tumor tissues Correlation between PD-L1 and AK112 in tumor tissues Up to approximately 2 years
