NCT ID NCT07128628
First seen Jun 27, 2026 · Last updated Jul 15, 2026 · Updated 2 times
Summary
This Phase 2 trial tests a new eye drop that combines two active ingredients—lifitegrast and perfluorohexyloctane—for people with dry eye disease. About 423 adults will use the drops twice daily for 4 weeks. Researchers will measure changes in eye surface staining and symptom scores to see if the combo works better than either ingredient alone or a placebo.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lifitegrast and perfluorohexyloctane eye drops
- What this could lead to
- If it works, this could offer a more effective twice-daily eye drop for dry eye symptoms like stinging and blurred vision.
- What could go wrong
- This is an early Phase 2 trial with only 4 weeks of treatment, so long-term benefits are unknown. The new combo may not work better than existing drops.
