At least one measurable lesion as assessed according to RECIST 1.1 within 4 weeks prior to randomization.
Major organs are functioning well.
Every effort should be made to provide tumor tissues for the determination of PD-L1 expression.
An ECOG PS score of 0 or 1.
An expected survival ≥ 12 weeks.
Subjects with prior denosumab use that can and agree to switch to bisphosphonate therapy for bone metastases starting prior to randomization and throughout treatment.
Participant must keep contraception.
Exclusion Criteria:
