Could this pill treat sleep apnea and hypertension at once?
NCT ID NCT06785454
First seen Jun 27, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This phase 2 trial tested a drug called lorundrostat in 48 adults with moderate-to-severe obstructive sleep apnea and high blood pressure. Participants took either the drug or a placebo for four weeks to see if it improved breathing during sleep and lowered blood pressure. The study is complete, and results will show whether this approach is worth testing further.

- Active substance
- Lorundrostat
- What this could lead to
- If successful, this could point toward a new oral treatment that reduces both sleep apnea severity and high blood pressure.
- What could go wrong
- This is a small, early-phase trial (48 people) with short follow-up. Results may not hold in larger studies or real-world use.
