New pill aims to tame stubborn high blood pressure
NCT ID NCT07489612
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new daily pill called QLS1410 in 260 adults whose high blood pressure remains high despite taking two or more medications. Participants will receive either QLS1410 or a placebo for 12 weeks. The main goal is to see if QLS1410 can lower systolic blood pressure more than placebo.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- QLS1410 tablet
- What this could lead to
- If it works, this could provide a new daily pill option for people whose high blood pressure is not controlled by current medications.
- What could go wrong
- This is an early Phase 2 trial with only 260 participants, so results may not apply to everyone. The drug is still experimental and may not lower blood pressure better than placebo.
