About this trial
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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
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.
Disqualifiers
For all Dose-Escalation cohorts: Prior treatment with zanzalintinib. For all Expansion Cohorts: Prior treatment with zanzalintinib, nivolumab, ipilimumab or relatlimab with the following exceptions: Prior PD-1/PD-L1, Lymphocyte-activation gene 3 (LAG-3) and cCytotoxic T lymphocyte associated protein 4 (CTLA-4) targeting therapy for locally advanced or metastatic disease is allowed for Cohort 2 (ccRCC), Cohort 5 (UC), Cohort 9 (NSCLC), and Cohort 12 (ccRCC), and prior treatment in the neoadjuvant or adjuvant setting is allowed for Cohort 13 and Cohort 14 (ccRCC 1L).
For all Dose-Escalation Cohorts and Expansion Cohort 2 (ccRCC), 3 (mCRPC), Cohort 5 (UC), Cohort 9 (NSCLC), Cohort 10 (CRC), and Cohort 12: Receipt of any type of small molecule kinase inhibitor (including investigational kinase inhibitor) within 2 weeks before first dose of study treatment.
For Cohort 3 (mCRPC): Receipt of abiraterone within 1 week; cyproterone within 10 days; or receipt of flutamide, nilutamide, bicalutamide, enzalutamide, or other androgen receptor inhibitors within 2 weeks before first dose of study treatment.
For all Dose-Escalation Cohorts and Expansion Cohort 2 (ccRCC), Cohort 3 (mCRPC), Cohort 5 (UC), Cohort 9 (NSCLC) and Cohort 10 (CRC), and Cohort 12: Receipt of any type of anticancer antibody or systemic chemotherapy within 4 weeks before first dose of study treatment.
