New drug runimotamab takes on Hard-to-Treat HER2 cancers
NCT ID NCT03448042
First seen Jun 27, 2026 · Last updated Aug 27, 2026 · Updated 2 times
Summary
This early-stage trial tests a new drug called runimotamab, alone or with trastuzumab, in 123 people with advanced HER2-positive cancers. The main goal is to check safety and how the drug moves through the body. It is for patients whose cancer has spread or cannot be removed by surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- runimotamab (with trastuzumab and tocilizumab as needed)
- What this could lead to
- If successful, this could lead to a new treatment option for people with advanced HER2-positive cancers that are hard to treat.
- What could go wrong
- This is an early phase 1 trial focused on safety and dosing, not yet on effectiveness. The drug may not work or could cause serious side effects.
