New pill shows promise for Hard-to-Treat ovarian cancer
NCT ID NCT06084416
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 1b trial tests an experimental oral drug called sovilnesib in 120 people with advanced high-grade serous ovarian cancer that has stopped responding to standard platinum chemotherapy. The goal is to find the safest and most effective dose while monitoring side effects and tumor response. Participants take sovilnesib tablets by mouth, and the study will measure how well the drug controls the cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sovilnesib (an oral KIF18A inhibitor)
- What this could lead to
- If successful, this could lead to a new oral treatment option for advanced ovarian cancer that has stopped responding to platinum-based chemotherapy.
- What could go wrong
- This is an early phase 1b trial with only 120 participants, so the drug may not prove effective or may have significant side effects. It is not a cure and aims to control the disease.
