Childbearing potential, has a negative serum pregnancy test at screening (within 7 days before the first investigational product administration), not be breast feeding, and agree to remain abstinent (refrain from heterosexual intercourse) or uses adequate contraceptive methods that result in a failure rate of <1% per year before study entry and throughout the study until 120 days after the last investigational product administration
  11. Male participants are eligible to participate in the study if they are vasectomized or agree to use contraception during the study treatment period and for at least 120 days after the last dose of study drug

Key

Exclusion Criteria
  1. History of severe hypersensitivity reactions to other humanized monoclonal antibodies
  2. Prior active malignancy within 2 years prior to Cycle 1 Day 1.
  3. Prior therapies targeting PD-1 or PD-L1.
  4. Active brain or leptomeningeal metastases as determined by computed tomography (CT) or magnetic resonance imaging (MRI) evaluation during screening and prior radiographic assessments.
  5. Participants with active autoimmune diseases or history of autoimmune diseases that may relapse should be excluded.
  6. Participants should be excluded if they have conditions requiring systemic treatment with either corticosteroids (>10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration.
  7. Has history of interstitial lung disease or non-infectious pneumonitis except for those induced by radiation therapies
  8. With severe chronic or active infections (including tuberculosis infection, etc) requiring systemic antibacterial, antifungal or antiviral therapy within 14 days prior to first dose of study drug.
  9. With uncontrollable pleural effusion, pericardial effusion or ascites requiring pleurocentesis or abdominal tapping less than 4 weeks
  10. Significant cardiovascular disease, such as New York Heart Association (NYHA) cardiac disease (Class II or greater), myocardial infarction within the previous 3 months, unstable arrhythmias, or unstable angina
  11. Known history of Human Immunodeficiency Virus (HIV)
  12. Participants with untreated chronic hepatitis B or chronic hepatitis B virus (HBV) carrier with HBV deoxyribonucleic acid (DNA) ≥500 IU/mL (or 2.5 × 103 cps/mL), or active hepatitis C should be excluded. Participant with inactive hepatitis B surface antigen (HBsAg) carrier, active HBV infection with sustained anti-HBV suppression (HBV DNA <500 IU/mL or 2.5 × 103 cps/mL) and participants whose hepatitis C has been cured (hepatitis C virus [HCV] ribonucleic acid [RNA] is lower than detection limit) can be enrolled
  13. Underlying medical conditions that, in the investigator's opinion, will make the administration of study drug hazardous or obscure the interpretation of toxicity determination or adverse events (AEs)
  14. Prior chemotherapy, radiotherapy, immunotherapy or any investigational therapies (including Chinese herbal medicine and Chinese patent medicines) used to control cancer within 2 weeks of Cycle 1 Day 1. AEs associated with these therapies must be Grade 0-1, baseline or stabilized (except for alopecia)
  15. Prior allogeneic stem cell or solid organ transplant
  16. Administration of a live or attenuated vaccine within 4 weeks prior to study drug administration

Duration of Response (DOR) as Assessed by IRCFrom the date of first dose up to approximately 2 years and 2 months

DOR - defined as the time from the first determination of a confirmed objective response by IRC according to RECIST version 1.1 until the first documentation of progression or death, whichever comes first

Overall Survival (OS)From the date of first dose up to approximately 2 years and 2 months

OS - defined as the time from the date of first dose of study drug until the date of death from any cause

ORR as Assessed by the InvestigatorsFrom the date of first dose up to approximately 2 years and 2 months

ORR is defined as the percentage of participants who had confirmed complete response (CR) or partial response (PR) as assessed by the investigators per RECIST version 1.1 and immune related RECIST (irRECIST)

DOR as Assessed by Investigators Per RECIST Version 1.1 and irRECISTFrom the date of first dose up to approximately 2 years and 2 months

DOR is defined as the time from the first determination of a confirmed objective response by the investigator according to RECIST version 1.1 and irRECIST until the first documentation of progression or death, whichever comes first

PFS as Assessed by Investigators Per RECIST Version 1.1 and irRECISTFrom the date of first dose up to approximately 2 years and 2 months

PFS is defined as the time from the date of first dose of study drug to the date of first documentation of disease progression assessed by the investigator according to RECIST version 1.1 and irRECIST until the first documentation of progression or death, whichever comes first

DCR as Assessed by Investigators Per RECIST Version 1.1 and irRECISTFrom the date of first dose up to approximately 2 years and 2 months

DCR is defined as the percentage of participants who achieve CR, PR and stable disease (SD) assessed by investigators per RECIST version 1.1 and irRECIST

Number of Participants Experiencing Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)From the date of first dose until End of Study (approximately 3 years and 9 months)

TEAE is defined as an adverse event (AE) that had an onset date or a worsening in severity from baseline pre-treatment) on or after the first dose of study drug up to 30 days following study drug .discontinuation. An SAE is any untoward medical occurrence that, at any dose that results in death or is life-threatening.
