Subjects must have adequate organ function. 10. Women of childbearing potential (WOBPC, as defined in section 13.5) must have a negative pregnancy test ≤7 days prior to the first dose of investigational product. WOBCP or fertile men and their WOBCP partners must agree to use an effective method of birth control from providing signed ICF and for 6 months after last dose of investigational product. Exclusion Criteria: 1. Histologically confirmed small cell lung cancer or containing small cell component. 2.

Outcomes

Primary Outcomes

Progression-free survival (PFS) in all subjects evaluated by investigators according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1

Time frame: up to approximately 5 years

Secondary Outcomes

Overall Survival (OS)

OS defined as the time from randomization to all-cause death.

Time frame: up to approximately 7 years

PFS assessed by BICR

PFS defined as the time from randomization to the first occurrence of disease progression or all-cause death (whichever occurs first), as determined by the BICR according to RECIST v1.1

Time frame: up to approximately 5 years

PFS in subgroup of participants with PD-L1 Expression≥1%, as determined by the investigator

PFS after randomization as determined by the investigator according to RECIST v1.1 in the subgroup of patients with PD-L1 expression ≥1% defined by the SP263 immunohistochemistry (IHC) assay.

Time frame: up to approximately 5 years

Objective Response Rate (ORR) assessed by the investigator according to RECIST v1.1

ORR, defined as the proportion of patients with a complete response (CR) or partial response (PR) on two consecutive occasions \>=4 weeks apart, as determined by the investigator according to RECIST v1.1.

Time frame: up to approximately 5 years

Duration of response (DOR) assessed by the investigator according to RECIST v1.1

DOR defined as the time between the date of the earliest qualifying response and the date of progressive disease or all-cause death, whichever occurs first, as determined by the investigator according to RECIST v1.1.

Time frame: up to approximately 5 years
