Brief Summary:

All subjects will receive zanzalintinib 100mg orally (PO) once daily plus nivolumab standard of care dosing (i.e., 240mg IV every 2 weeks or 480mg IV every 4 weeks) for a total of 12 weeks, followed by restaging scan/evaluation for surgical operability and an adaptive approach that includes (1) surgical resection if the participant is eligible for surgery (Cohort A), (2) up to 48 weeks total (from Cycle 1 Day 1) of zanzalintinib plus nivolumab if the participant has partial response or stable disease but remains inoperable (Cohort B1), or (3) stopping protocol mandated treatment to receive standard of care systemic therapy and continue follow up per protocol if the participant has disease progression (Cohort B2).
