Primary Outcome Measures
NameTimeMethod
Objective response rate (ORR)Up to 2 years

ORR is defined as the proportion of subjects with confirmed CR or PR, based on RECIST v1.1.

Secondary Outcome Measures
NameTimeMethod
Progression-free survival (PFS)Up to 2 years

Progression-free survival is defined as the time from the start of treatment with AK104 until the first documentation of disease progression or death due to any cause, whichever occurs first.

Duration of response (DoR)Up to 2 years

Duration of response is defined as the duration from the first documentation of objective response to the first documented disease progression or death due to any cause, whichever occurs first

Disease control rate (DCR)Up to 2 years

The DCR is defined as the proportion of subjects with CR, PR, or SD (subjects achieving SD will be included in the DCR if they maintain SD for ≥8 weeks) based on RECIST Version 1.1.

Number of participants with adverse events (AEs)the time of informed consent signed through 90 days after the last dose of AK104 and

An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product temporally associated with the use of study treatment, whether or not considered related to the study treatment.

Observed concentrations of AK104From first dose of AK104 through 90 days after last dose of AK104

The endpoints for assessment of PK of AK104 include serum concentrations of AK104 at different timepoints after AK104 administration.

Number of subjects who develop detectable anti-drug antibodies (ADAs)From first dose of AK104 through 90 days after last dose of AK104

The immunogenicity of AK104 will be assessed by summarizing the number of subjects who develop detectable antidrug antibodies (ADAs).
