New pill targets HER2 cancers in phase 2 trial
NCT ID NCT06581432
First seen Jun 27, 2026 · Last updated Sep 16, 2026 · Updated 12 times
Summary
This study tests an oral drug called zongertinib in adults with advanced solid tumors that have HER2 mutations or overexpression and have not responded to prior treatment. Participants take one of two daily doses and continue as long as they benefit. Doctors regularly check tumor size and overall health to see if the drug shrinks tumors and how safe it is.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- zongertinib (a daily oral drug that blocks HER2, a protein that can fuel cancer growth)
- What this could lead to
- If successful, zongertinib could offer a new treatment option for people with advanced cancers that have HER2 changes and have stopped responding to other therapies.
- What could go wrong
- This is an early-phase (Phase 2) trial with no control group, so results are preliminary. The drug may not shrink tumors in many participants, and side effects are still being studied.
This is an AI summary of the original study and may miss details. Read our disclaimer.
