| Measure | Time frame | Description |
|---|---|---|
| Number of participants experiencing dose-limiting toxicities (DLTs) | From Day 1 to Day 28 after the first tumour vaccine was administrated in safety run-in cohorts | Number of participants who meet the criteria of dose-limiting toxicities (DLTs) in DLT observation period |
| Number of participants with adverse events (AEs) and severity | From ICF up to 30 days after last study treatment | Number of participants experiencing adverse events (AEs) and severity, graded according to CTCAE v5.0 |
| Objective Response Rate (ORR) | Time Frame: Up to 2 years | Proportion of participants with complete response (CR) or partial response (PR), as assessed by RECIST version 1.1 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Progression free survival (PFS) | Up to 2 years | Time from the date of enrollment until the first documentation of disease progression or death due to any cause, whichever occurs first, as assessed by RECIST version 1.1 |
| Disease control rate (DCR) | Up to 2 years | Proportion of participants with complete response (CR), partial response (PR), or stable disease (SD), as assessed by RECIST version 1.1 |
| Duration of response (DoR) | Up to 2 years | Time from the first documentation of objective response to the first documented disease progression as assessed by RECIST version 1.1 or death due to any cause, whichever occurs first |
| Time to response (TTR) | Up to 2 years | Time from the start of the treatment to the first objective tumor response observed for patients who achieved complete response (CR) or partial response (PR), as assessed by RECIST version 1.1 |
| Overall survival (OS) | Up to 2 years | Time from the date of enrollment to death from any cause |
| Observed concentrations of AK112 | Up to 2 years | Observed serum concentrations of AK112 at different time points after AK112 administration |
