Cabozantinib Dose Skipping as an Alternative to Dose Reductions
Source: ClinicalTrials.gov · Last updated 31 Aug 2026
Brief summary (registry, in English)
The goal of this study is to determine if an alternative cabozantinib dosing regimens results in a similar drug exposure compared to the standard regimens in patients with metastatic renal cell carcinoma (mRCC). All dosages of cabozantinib (20 ,40, 60mg) have the same price, and cabozantinib is eliminated very slowly by the body. This means that using fewer tablets could potentially lead to cost savings, while remaining equally effective. The main questions it aims to answer are: * Is the drug exposure from our experimental regimens similar to the standard dosing regimens? * Do the experimental regimens affect the number of side effect and the patients' quality of life? Participants will: * Take cabozantinib according to either the experimental or standard dosage regimen for 4 weeks * After 4 weeks: visit the clinic to collect some blood samples and complete two questionnaires. * 1 and 3 days after this visit: visit the clinic to collect 1 blood sample. * The day after the hospital visit: switch to the other dosing regimen and according to that regimen for another 4 weeks. * After 4 weeks: visit the clinic to collect some blood samples and complete two questionnaires * 1 and 3 days after this visit: visit the clinic to collect 1 blood sample.
