Inclusion criteria
. Participants must have unresectable advanced or metastatic RCC with a predominant clear cell histologic component .
. At least three bone metastases are present and detectable on bone scan, and at least one bone metastasis is NOT planned to be treated with radiation therapy.
. Previously treated with 1-3 prior lines of therapy in at least one of the following settings:
. Metastatic setting; must have received combination therapy containing either programmed cell death protein 1 (PD-1) inhibitor/cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitor or PD-1 inhibitor/vascular endothelial growth factor receptor (VEGFR)-targeting tyrosine kinase inhibitors (TKI).
. Adjuvant setting; must have received pembrolizumab and have had documented progression of disease within 1 year of the first dose of pembrolizumab .
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Proportion of participants who have not progressed at 12 months (PFS12)
. Has seen a dentist within 90 days prior to enrollment and been cleared to receive bone-strengthening agents.
. Availability of a representative formalin fixed, paraffin embedded tumor specimen or fresh frozen tissue specimen that enables the definitive diagnosis of RCC, accompanied by an associated pathology report. If stored specimens are not available, an optional biopsy may be performed and specimens can be collected by surgical resection or biopsy of the primary tumor or biopsy or resection of a metastatic lesion.
Exclusion criteria
. Prior treatment with zanzalintinib for RCC.
. Receipt of any small molecule kinase inhibitor (including investigational) or vascular endothelial growth factor (VEGF)-targeted therapy within 2 weeks before the first dose of study treatment.
. Known brain metastases or cranial epidural disease unless adequately treated with radiotherapy and/or surgery (including radiosurgery) and stable for at least 4 weeks before first dose of study treatment. Note: Eligible subjects must be neurologically asymptomatic and without corticosteroid treatment at the time of enrollment. Note: Base of skull lesions without definitive evidence of dural or brain parenchymal involvement are allowed.
. Incomplete healing from prior radiotherapy as determined by the treating radiation oncologist or treating investigator.
. Participation in an experimental drug study within 28 days of study enrollment.
. History of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins.
. Pregnant and lactating women are excluded from this study because zanzalintinib is an investigational product 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.
