• Subjects who received non-thoracic radiotherapy >30 Gy within 4 weeks prior to the first dose, or thoracic radiotherapy >30 Gy within 24 weeks prior to the first dose study drug.

• History of gastrointestinal perforation and/ or fistula within 6 months prior to the first dose of study drug.

• Known history of primary immunodeficiency virus infection.

• Known history of allogeneic organ transplantation or allogeneic hematopoietic stem cell transplantation.

• Known history of interstitial lung disease.

• Known history of active tuberculosis (TB).

• Serious infections within 4 weeks prior to the first dose of study drug, including but not limited to complications requiring hospitalization, sepsis or severe pneumonia.

• An active infection requiring systemic therapy.

• Subjects with untreated chronic hepatitis B or chronic hepatitis B virus (HBV) DNA exceeding 500 IU/ mL or active hepatitis C virus (HCV) should be excluded. Subjects with non-active HBsAg carriers, treated and stable hepatitis B (HBV DNA <500 IU/ mL) , and cured hepatitis C can be enrolled. Subjects with positive HCV antibodies are eligible only if the HCV RNA test results are negative.

• Known history of testing positive for human immunodeficiency virus (HIV).

• Presence of central nervous system (CNS) metastasis, meningeal metastasis, spinal cord compression, or leptomeningeal disease.

• Uncontrolled pleural effusion, pericardial effusion, or ascites requiring repeated drainage.

• Clinically active hemoptysis, active diverticulitis, peritoneal abscess, or gastrointestinal obstruction.

• Clinically significant bleeding symptoms or significant bleeding tendency such as gastrointestinal bleeding, hemorrhagic gastric ulcer or vasculitis within 1 month prior to the first dose of study treatment.

• Unresolved toxicities from prior anticancer therapy, defined as having not resolved to NCI CTCAE v4.03 Grade 0 or 1, or to levels dictated in the inclusion/exclusion criteria, with the exception of alopecia.

• Receipt of live or attenuated vaccination within 30 days prior to the first dose of study treatment, or plan to receive live or attenuated vaccine during the study.

• Known history of server hypersensitivity to other monoclonal antibodies.

• Known severe allergic reactions to paclitaxel, carboplatin, or their preventive medications.

• Grade 2 or greater peripheral neuropathy (based on NCI CTCAE v4.03 criteria)

• Known allergic reactions to any ingredients of AK105.

• Pregnant or lactating women.

• Any conditions that, in the investigator's opinion, may put subjects treated with the study drug at risks, or interfere with the evaluation of study drug or subject safety, or the interpretation of study results.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression-free survival (PFS) in intent-to-treat (ITT) population, assessed by Independent Radiologist Review Committee(IRRC) in accordance with RECIST v1.1	PFS is defined as the time from the date of randomization till the first documentation of disease progression (per RECIST v1.1 criteria) assessed by IRRC or death due to any cause (whichever occurs first).	Up to approximately 2 years
Primary	PFS in PD-L1-selected population, assessed by IRRC in accordance with RECIST v1.1	PFS is defined as the time from the date of randomization till the first documentation of disease progression (per RECIST v1.1 criteria) assessed by IRRC or death due to any cause (whichever occurs first).	Up to approximately 2 years
Secondary	Overall survival (OS) in ITT population	OS is the time from the date of randomization to death due to any cause.	Up to approximately 2 years
Secondary	Overall survival (OS) in PD-L1-selected population	OS is the time from the date of randomization to death due to any cause.	Up to approximately 2 years
Secondary	PFS assessed by the investigator in accordance with RECIST v1.1	PFS is defined as the time from the date of randomization till the first documentation of disease progression (per RECIST v1.1 criteria) assessed by the investigator or death due to any cause (whichever occurs first).	Up to approximately 2 years
Secondary	Objective Response Rate (ORR)	ORR is the proportion of subjects with CR or PR , based on RECIST v1.1.	Up to approximately 2 years
Secondary	Duration of response (DoR)	DoR 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.	Up to approximately 2 years
