* Patients with psychiatric illness/social situations that would limit compliance with study requirements.
* Pregnant or lactating women are excluded from this study because zanzalintinib is an agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with zanzalintinib, breastfeeding should be discontinued if the mother is treated with zanzalintinib.
