Study Arms (2)

BL-B01D1+Tislelizumab

EXPERIMENTAL

Participants receive BL-B01D1+Tislelizumab in the first cycle (3 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.

Drug: BL-B01D1Drug: Tislelizumab

Carboplatin+Etoposide +Tislelizumab

ACTIVE COMPARATOR

Participants receive Carboplatin+Etoposide +Tislelizumab in the first cycle (3 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.

Drug: TislelizumabDrug: CarboplatinDrug: Etoposide

Interventions

Administration by intravenous infusion for a cycle of 3 weeks.
