Could fasting 14 hours a night help cancer immunotherapy work better?
NCT ID NCT06603155
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to see if limiting food intake to a 10-hour window each day (with 14 hours of nightly fasting) could improve how well immunotherapy works in people with advanced head/neck or kidney cancer. Researchers planned to track changes in gut bacteria and immune markers. However, the trial was withdrawn before any participants were enrolled, so no results are available.

- Active substance
- time restricted eating (TRE)
- What this could lead to
- If successful, this could point toward a simple dietary strategy to boost the effectiveness of immunotherapy in certain cancers.
- What could go wrong
- This trial was withdrawn before enrolling any participants, so no data exists. The approach is still very early and unproven.
