NCT ID NCT06846554
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 2 trial tests an experimental drug called APL-9796 in 48 adults with pulmonary hypertension (high blood pressure in the lungs). The study aims to see if the drug is safe, tolerable, and effective. Participants receive injections under the skin, and researchers monitor side effects, heart function, and walking ability.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- APL-9796 (an experimental drug given as injections under the skin)
- What this could lead to
- If successful, this could point toward a new treatment option for pulmonary hypertension, potentially improving heart and lung function.
- What could go wrong
- This is an early Phase 2 trial with only 48 participants, so results may not apply to everyone. The drug may cause side effects or prove no better than existing treatments.
