Zanzalintinib for Metastatic Clear Cell Kidney Cancer with Bone Metastases

This study is testing a drug called zanzalintinib along with a bone-strengthening agent for people with clear cell kidney cancer that has spread to the bones. You might be able to join if your cancer has spread and has already been treated with 1 to 3 other therapies, including at least one immune-based treatment. The main goal is to see what percentage of participants do not have their cancer grow or spread after 12 months. The study is currently recruiting 20 participants, but its overall status is unclear.

Study design
This is a single-institution, phase 2 study involving 20 participants. It is testing zanzalintinib plus an investigator-chosen bone strengthening agent.
What's involved
You would receive zanzalintinib by mouth and a bone strengthening agent through an IV. You would also undergo bone scans and CT scans.
Compensation
Not stated in the trial record.
Follow-up
The main goal looks at how long you go without your cancer growing or spreading, up to 12 months.

  • Proportion of participants who have not progressed at 12 months (PFS12)Up to 12 months

    The proportion of participants who have not demonstrated radiographic progression as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 or demonstrated clinical progression-free survival (PFS) at 12 months after the start of study treatment. Twelve-month landmark PFS rate will be obtained with 95% confidence interval using the Kaplan-Meier method.
