What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of participants with a Dose Limiting Toxicity (DLT)
Time Frame: During the first 4 weeks
DLTs will be assessed during the first 4 weeks of treatment for dose-escalation I 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, inter-current illness, or concomitant medications that occurs within the first 2 cycles (4 weeks) of treatment
During the first 4 weeks
Number of participants with adverse events (AEs)
Time Frame: From the participant signs the ICF to 30 days (AE) and 90 days (SAE) after the last dose of study treatment or initiation of other anti-tumor therapy, whichever occurs first.
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
From the participant signs the ICF to 30 days (AE) and 90 days (SAE) after the last dose of study treatment or initiation of other anti-tumor therapy, whichever occurs first.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Serum PK concentration of AK150
Time Frame: From pre-dose to the end of the last dose, an average of 6 months.
Serum PK of AK150 at different timepoints after AK150 administration
From pre-dose to the end of the last dose, an average of 6 months.
The immunogenicity of AK150
Time Frame: From pre-dose to 30 days post end of treatment
The immunogenicity of AK150 will be assessed by summarizing the number of participants who develop detectable anti-drug antibodies (ADAs)
From pre-dose to 30 days post end of treatment
Overall response rate (ORR)
Time Frame: Up to 12 year.
Efficacy measures such as ORR, which is the proportion of participants with CR or PR by investigator based on RECIST v1.1
Up to 12 year.
Progression-Free Survival(PFS)
Time Frame: Up to 1 year
PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first assessed by investigator Per RECIST 1.1.
Up to 1 year
Disease control rate(DCR)
Time Frame: Up to 1 year.
DCR, which is defined as the proportion of subjects with CR, PR, or SD, based on RECIST v1.1.
Up to 1 year.
