Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with histologically confirmed advanced renal cell carcinoma who are currently stable on cabozantinib.

Probably not a fit

Patients with gastrointestinal abnormalities affecting drug absorption or those unable to follow the light breakfast protocol may not benefit from this study.

What this trial studies

This study investigates the pharmacological effects of taking cabozantinib, a drug used to treat advanced renal cell carcinoma, with a light breakfast instead of on an empty stomach. The aim is to determine if this approach can reduce side effects such as nausea and diarrhea while improving drug absorption. Participants will be required to maintain a stable dosage of cabozantinib for at least four weeks prior to the study. The study will assess the tolerability and effectiveness of this modified intake method in patients already receiving cabozantinib as monotherapy.

Why it matters

Potential benefit: If successful, this approach could enhance the tolerability of cabozantinib, potentially improving patient adherence and outcomes.

How similar studies have gone: While the specific approach of taking cabozantinib with food is novel, similar studies on food-drug interactions have shown promising results in improving drug efficacy and reducing side effects.
