|Condition or disease||Intervention/treatment||Phase|
|Neoplasms Malignant||Drug: AK112||Phase 1|
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||151 participants|
|Intervention Model:||Sequential Assignment|
|Intervention Model Description:||Sequential Assignment Initially, a single-subject cohort will be enrolled at the protocol starting dose of AK112 every 2 weeks (Q2W). Dose escalation will proceed to the next main dose level according to the 3+3+3 dose-escalation procedure until the MTD is reached. Dose expansion phase of the study will be initiated at the Sponsor's discretion at the dose level and treatment schedule which was established as the recommended Phase 2 dose (RP2D) in the dose-escalation phase.|
|Masking:||None (Open Label)|

AK112 IV every 2 weeks (q2w) or every 3 weeks (q3w)
AK112 is a PD1/VEGF bispecific antibody.
- Incidence and nature of participants with adverse events (AEs) [ Time Frame: From time ICF is signed until 90 days after last dose of AK112 ]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 DLTs [ Time Frame: During the first four weeks of treatment with AK112 ]DLTs will be assessed during the dose-escalation phase and are defined as toxicities that meet pre-defined severity criteria and assessed as having a suspected relationship to study drug, and unrelated to disease, disease progression, intercurrent illness, or concomitant medications that occurs within the first cycle (4 weeks) of treatment.
- 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 ]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 at 16 and 24 weeks respectively) based on RECIST Version 1.1.
- Progression-free survival (PFS) [ Time Frame: Up to 2 years ]Progression-free survival is defined as the time from the start of treatment with AK112 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 with AK112 until death due to any cause.
- Area under the curve (AUC) of AK112 for assessment of pharmacokinetics [ Time Frame: From first dose of AK112 through 90 days after last dose of AK112 ]The endpoints for assessment of PK of AK112 include serum concentrations of AK112 at different timepoints after AK112 administration.
- Maximum observed concentration (Cmax) and Minimum observed concentration (Cmin) of AK112 [ Time Frame: From first dose of AK112 through 90 days after last dose of AK112 ]The endpoints for assessment of PK of AK112 include serum concentrations of AK112 at different timepoints after AK112 administration.
- Number of subjects who develop detectable anti-drug antibodies (ADAs) [ Time Frame: From first dose of AK112 through 90 days after last dose of AK112 ]The immunogenicity of AK112 will be assessed by summarizing the number of subjects who develop detectable anti-drug antibodies (ADAs).
