New drug hopes to shrink tumors in patients out of options
NCT ID NCT07306559
First seen Jun 25, 2026 · Last updated Aug 21, 2026 · Updated 9 times
Summary
This study tests a new drug called BI 3820768 in adults with advanced germ cell tumors, endometrial cancer, or ovarian cancer who have run out of treatment options. The drug aims to help the immune system fight cancer. Researchers will give increasing doses to find a safe amount that may shrink tumors. Participants receive weekly injections for 6 weeks, then every 3 weeks, and are followed for up to 3 years.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BI 3820768
- What this could lead to
- If this works, it could point toward a new treatment option for people with advanced cancers that have not responded to other therapies.
- What could go wrong
- This is a very early Phase 1 trial, so the drug may not work or may cause serious side effects. It is the first time this drug is tested in humans, so success is uncertain.
