Can a Real-World registry improve how treprostinil is used for PAH?
NCT ID NCT07736846
First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This registry follows adults newly diagnosed with pulmonary arterial hypertension (PAH) who are starting treatment with parenteral treprostinil, a medication given as a continuous infusion under the skin or into a vein. Researchers will collect data from routine care—including dosing, side effects, and how well patients are doing—over at least three years. The goal is to understand how treprostinil is actually used in practice and what outcomes patients experience.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- treprostinil given as a continuous infusion under the skin or into a vein
- What this could lead to
- If successful, this registry could provide a clearer picture of how treprostinil works in everyday practice, helping doctors optimize treatment for people with PAH.
- What could go wrong
- This is an observational registry, not a controlled trial, so it cannot prove cause and effect. Results may be influenced by differences in patient care across centers.

Who is studied
The registry will include approximately 100-300 adult patients (≥18 years of age) with confirmed pulmonary arterial hypertension (PAH), classified as Group 1 according to the prevailing ESC/ERS guidelines, who initiated parenteral treprostinil administered subcutaneously or intravenously on or after January 1, 2024. Written informed consent will be required for prospective data collection and for retrospective medical chart review, as applicable under local regulations.
