WHO or Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
Adequate organ and bone marrow function.

Participants with small-cell lung cancer or mixed small-cell lung cancer.
History of active primary immunodeficiency.
History of non-infectious ILD/pneumonitis that required steroids, has current ILD/pneumonitis, or has suspected ILD/pneumonitis that cannot be ruled out by imaging at screening.
Participants who have preoperative radiotherapy treatment as part of their care plan.
Participants who require or may require pneumonectomy, segmentectomies, or wedge resections, as assessed by their surgeon at baseline, to obtain potentially curative resection of primary tumour.
QTcF (QT interval corrected by Fridericia's formula) interval ≥ 470 ms.
Any medical contraindication to treatment with chemotherapy as listed in the local labelling.
Participants with moderate or severe cardiovascular disease.
Any concurrent chemotherapy, investigational product, biologic, or hormonal therapy for cancer treatment.
Receipt of live attenuated vaccine within 30 days prior to the first dose of study interventions.
Prior exposure to approved or investigational immune-mediated therapy including, but not limited to, other anti-CTLA-4, anti-PD-1, anti-PD-L1, and anti-PD-L2 antibodies. Participants who received agents targeting the adenosine pathway, anti-NKG2A, anti-HLA-E agents, and anti-LIF agents are also excluded. Participants who have received previous treatment with a TROP2 targeting ADC or with another ADC containing a chemotherapy agent that inhibits TOP1 activity are also excluded.
Current or prior use of immunosuppressive medication within 14 days before the first dose of study interventions.
Active or uncontrolled infections including HBA, HBV, HCV, and HIV.
