Outcome Measures

Primary Outcome Measures

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

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