- Subject must have at least one measurable lesion according to RECIST Version1.1.
- Adequate organ function.
- Female subjects of childbearing potential and male subjects with female partners of childbearing potential must agree to use effective barrier methods of contraception during the study and for 120 days after last dose of study drug.

- Receipt of any anti-CD73 treatment.
- Anticancer therapy within 4 weeks prior to the first dose of investigational product.
- Experienced a toxicity that led to permanent discontinuation of prior immunotherapy.
- Subjects with spinal cord compression or active brain metastases, except for subjects with untreated and asymptomatic brain metastases or with stable brain metastases after treatment.
- Subjects with pleural effusion, pericardial effusion, or ascites requiring repeated drainage.
- Subjects whose imaging shows that the tumor has invaded important blood vessels or the investigator judges that the tumor is very likely to invade important blood vessels and cause fatal bleeding during the study.

Group Intervention Description AK131 AK131 Subjects will receive AK131 via intravenously (IV) Q2W or Q3W, up to 2 years
- Primary Outcome Measures
Name Time Method Number of subjects with adverse events (AEs) From the time of informed consent signed through 90 days after the last dose of study drug AE refers to any untoward medical occurrence or deterioration of existing medical event after the subject signed the ICF, whether or not considered related to the study treatment.
Number of subjects with dose limiting toxicities (DLTs) During the first 4 weeks DLTs will be assessed during the first 4 weeks of treatment. DLTs 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 DLT observation period.
- Secondary Outcome Measures
Name Time Method Number of subjects who develop detectable anti-drug antibodies (ADAs) From first dose of study drug through 30 days after last dose of study drug The immunogenicity of AK131 will be assessed by summarizing the number of subjects who develop detectable anti-drug antibodies (ADAs)
Time to response (TTR) Up to approximately 2 years TTR is defined as the time from the start of the treatment to the first objective tumor response observed for patients who achieved CR or PR (based on RECIST Version 1.1).
Serum PK concentration of AK131 From first dose of study drug through 30 days after last dose of study drug Serum PK concentration of AK131 in individual subjects at different time points after AK131 administration
Objective response rate (ORR) Up to approximately 2 years ORR is defined as the proportion of subjects with confirmed CR or confirmed PR (based on RECIST Version 1.1).
Disease control rate (DCR) Up to approximately 2 years DCR is defined as the proportion of subjects with CR, PR, or SD (based on RECIST Version 1.1).
Duration of Response (DoR) Up to approximately 2 years DoR is defined as the duration from the first documentation of objective response to the first documented disease progression (based on RECIST Version 1.1) or death due to any cause, whichever occurs first.
Overall survival (OS) Up to approximately 2 years OS defined as the time from the first dose to death from any cause.
Progression-free survival (PFS) Up to approximately 2 years PFS is defined as the time from the start of treatment until the first documentation of disease progression (based on RECIST Version 1.1) or death due to any cause, whichever occurs first.
