New painkiller may replace opioids in liver cancer procedure
NCT ID NCT07034950
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests esketamine, a drug related to ketamine, to control pain during a procedure that destroys liver tumors with heat. The goal is to find the right dose that works without needing opioids, which can cause breathing problems. 79 adults with liver cancer will receive esketamine during the procedure, and researchers will monitor their pain and breathing safety.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- esketamine
- What this could lead to
- If successful, this could provide a safer, opioid-free way to manage pain during liver tumor ablation, reducing breathing complications.
- What could go wrong
- This is an early-phase dose-finding study with only 79 participants. The results may not apply to all patients, and esketamine itself can cause side effects like dizziness or nausea.
