NCT ID NCT07626528
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a traditional Chinese medicine formula, Wenyang Tongbi Granules, can reduce nerve pain and numbness caused by chemotherapy. 144 adults with breast or colorectal cancer who develop hand-foot tingling or pain during chemo will receive either the herbal granules or standard mecobalamin pills for 42 days. Researchers will measure symptom improvement and changes in blood markers of inflammation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Wenyang Tongbi Granules (traditional Chinese herbal formula)
- What this could lead to
- If it works, this could offer a new option to ease nerve pain and numbness caused by chemotherapy, improving quality of life for cancer patients.
- What could go wrong
- This is a very early (Phase 1) trial with only 144 people, so results may not be conclusive. The herbal formula may not work better than existing treatments, and side effects are not yet well understood.
