Malaria drug artesunate tested for rare lung condition
NCT ID NCT06872112
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage study is testing whether artesunate, a drug used for malaria, is safe for people with pulmonary arterial hypertension (PAH). Fifteen adults with PAH will take increasing doses of artesunate capsules for 20 weeks. The main goal is to check for side effects, not yet to see if it works.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- artesunate (oral capsules)
- What this could lead to
- If safe and effective, artesunate could become a new treatment option for pulmonary arterial hypertension, potentially improving blood flow and symptoms.
- What could go wrong
- This is a very early Phase 1 trial with only 15 people, focused on safety. It is too small to prove if artesunate actually helps PAH, and side effects are unknown.
