Study of Zanzalintinib in Combination With Immuno-Oncology Agents in Participants With Solid Tumors

Key Inclusion Criteria: * Cytologically or histologically confirmed solid tumor that is unresectable, locally advanced or metastatic. * Dose-Escalation Cohorts: Participants with a solid tumor that is unresectable or metastatic and for which life-prolonging therapies do not exist or available therapies are intolerable or no longer effective. * Expansion Cohort 1 (ccRCC): Participants with unresectable advanced or metastatic RCC with a clear cell component who have not received prior systemic therapy. * Note: Prior non-vascular endothelial growth factor (VEGF) targeted adjuvant or neoadjuvant is allowed if disease recurrence occurred 6 months after the last dose. * Expansion Cohort 2 (ccRCC): Participants with unresectable advanced or metastatic RCC with a clear cell component. * Must have radiographically progressed after a combination therapy consisting of a Programmed Cell Death Protein 1 (PD-1)/Programmed death-ligand 1 (PD-L1) targeting monoclonal antibody (mAb) with a Vascular endothelial growth factor (receptor) tyrosine kinase inhibitor (VEGFR-TKI) or a PD-1 targeting mAb with a CTLA-4 mAb as the preceding line of therapy. * Must have received no more than one prior systemic anticancer therapy for unresectable advanced or metastatic renal cell carcinoma. * Expansion Cohort 3 (mCRPC): Men with metastatic adenocarcinoma of the prostate. * Must have progressed during or after one novel hormone therapy (NHT) given for castration-sensitive locally advanced (T3 o…
