- Incidence and Nature of Adverse Events (AEs) [ Time Frame: From the time of informed consent signed through to 90 days after end of treatment ]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.
- Number of participants with a Dose Limiting Toxicity (DLT) [ Time Frame: Within the first six weeks of treatment ]DLTs will be assessed during the first treatment cycle and assessed as having a suspected relationship to study drug according to pre-specific criteria in the protocol.
- Objective response rate (ORR) [ Time Frame: Up to 2 years ]The ORR is defined as the proportion of subjects with confirmed CR or confirmed PR, based on RECIST Version 1.1.
- Disease control rate (DCR) [ Time Frame: Up to 2 years ]Progression-free survival is defined as the time from the start of treatment with AK127 + AK104 until the first documentation of disease progression or death due to any cause, whichever occurs first.
- Progression-free survival (PFS) [ Time Frame: Up to 2 years ]Progression-free survival is defined as the time from the start of treatment until the first documentation of disease progression or death due to any cause, whichever occurs first.
- Overall survival (OS) [ Time Frame: Up to 2 years ]Overall survival is defined as the time from the start of treatment until death due to any cause.
- Area under the curve (AUC) of AK127+AK104 for assessment of pharmacokinetics [ Time Frame: From first dose of treatment through to 90 days after end of treatment ]The endpoints for assessment of PK including serum concentrations of AK127+AK104 at different timepoints after treatment administration.
- Maximum observed concentration (Cmax) of AK127 + AK104 [ Time Frame: From first dose of treatment through to 90 days after end of treatment. ]The endpoints for assessment of PK of AK127+AK104 include serum concentrations of AK127+AK104 at different timepoints after treatment administration.
- Minimum observed concentration (Cmin) of AK127+AK104 [ Time Frame: From first dose of treatment through to 90 days after end of treatment ]The endpoints for assessment of PK of AK127+AK104 include serum concentrations of AK127+AK104 at different timepoints after treatment administration.
- Number of subjects who develop detectable anti-drug antibodies (ADAs) [ Time Frame: From first dose of treatment through to 90 days after end of treatment ]The immunogenicity of AK127+AK104 will be assessed by summarizing the number of subjects who develop detectable anti-drug antibodies (ADAs).
