About this study

This is a multicenter Phase 1b, open label, dose-escalation and cohort-expansion study, evaluating the safety, tolerability, pharmacokinetics (PK), preliminary antitumor activity, and effect of biomarkers of zanzalintinib administered alone, and in combination with nivolumab (doublet), nivolumab + ipilimumab (triplet) and nivolumab + relatlimab (triplet) in participants with advanced solid tumors. In the Expansion Stage, the safety and efficacy of zanzalintinib as monotherapy and in combination therapy will be further evaluated in tumor-specific Expansion Cohorts.
