At least one measurable lesion as assessed by the Investigator according to RECIST v1.1 criteria (Only applicable to backfill participants in phase 1a and participants in phase 1b/2a).

Has adequate organ function within 7 days prior to the first dose of study treatment.\n8. Has adequate treatment washout period prior to the first dose of study treatment.\n9. Is willing to provide pre-existing resected tumor samples when available or undergo fresh tumor biopsy if feasible for the measurement of B7-H3/PD-L1 level and other biomarkers if no contraindication.\n\n Note: there is no minimum B7-H3/PD-L1 expression level mandatory for entry into the study.\n10.

Has a history of underlying pulmonary disorder including, but not limited to, pulmonary emboli within 3 months of the start of study treatment, severe asthma, severe COPD, restrictive lung disease, and other clinically significant pulmonary compromise or requirement for supplemental oxygen.\n7. Has an active autoimmune disease that has required systemic treatment in past 2 years (i.e., with use of disease modifying agents, corticosteroids, or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is allowed.\n8. Has an uncontrolled infection requiring intravenous injection of antibiotics, antivirals, or antifungals within 2 weeks before first dose of study treatment.\n9. Know human immunodeficiency virus (HIV) infection.\n10. Has spinal cord compression or clinically active central nervous system (CNS) metastases, defined as untreated and symptomatic, or requiring therapy with corticosteroids or anticonvulsants to control associated symptoms. Participants with asymptomatic CNS metastases who are radiologically and neurologically stable for at least 4 weeks following CNS-directed therapy (defined as 2 brain images, same imaging modality, both of which are obtained after treatment to the brain metastases; these imaging scans should be obtained at least 4 weeks apart and show no evidence of intracranial progression), and are on stable or decreasing doses of corticosteroids equivalent to ≤10 mg/day prednisone are eligible for study entry.\n\nNOTE: Other protocol defined Inclusion/Exclusion criteria may apply."},
