New bladder pain pill shows promise in early trial
NCT ID NCT06752603
First seen Jun 27, 2026 · Last updated Jul 08, 2026 · Updated 2 times
Summary
This Phase 2 trial tests whether a once-daily tablet called ONO-1110 can safely reduce bladder pain in people with Hunner type interstitial cystitis, a painful bladder condition. About 50 Japanese adults will receive either the drug or a placebo for 12 weeks. The main goal is to see if pain scores improve compared to placebo.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ONO-1110 (tablet taken once daily)
- What this could lead to
- If successful, this could point toward a new daily pill to ease chronic bladder pain in people with Hunner type interstitial cystitis.
- What could go wrong
- This is an early Phase 2 trial with only 50 participants in Japan, so results may not apply to other groups. The drug may not reduce pain better than placebo, and side effects are still being studied.
