New gel aims to stop chemo side effect that makes hands hurt
NCT ID NCT07457671
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a gel called TAR-0520 to see if it can prevent hand-foot syndrome, a painful skin reaction caused by the chemotherapy drug capecitabine. About 25 people with breast or colorectal cancer will apply the gel to their hands twice daily for 12 weeks. Their feet will not be treated and will serve as a comparison. The goal is to check if the gel is safe and reduces the severity of hand-foot syndrome.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- TAR-0520 gel
- What this could lead to
- If it works, this could point toward a way to prevent painful hand-foot syndrome in cancer patients taking capecitabine, improving their quality of life.
- What could go wrong
- This is a small, early-phase study with only 25 people. It may not show clear benefit, and the gel could cause local skin reactions or not reduce symptoms enough to matter.
