Real-world study explores new drug for breast cancer
NCT ID NCT05851677
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study is looking at how well a drug called Disitamab vedotin (RC48-ADC) works for breast cancer patients in real-world settings, outside of strict clinical trials. Researchers will track 45 patients to see how long they live without their cancer getting worse and what side effects occur. The goal is to understand the drug's true effectiveness and safety when used in everyday medical practice.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Disitamab vedotin (RC48-ADC)
- What this could lead to
- If successful, this could provide real-world evidence that Disitamab vedotin is a safe and effective treatment option for breast cancer patients.
- What could go wrong
- This is a small, observational study with only 45 participants, so results may not apply to all breast cancer patients. It is not a randomized controlled trial, so effectiveness is uncertain.
