Summary

This phase 3 trial is testing whether a once-daily inhaled medication called treprostinil palmitil can help adults with pulmonary arterial hypertension (PAH) walk farther. About 344 participants will receive either the drug or a placebo for 24 weeks. The main goal is to see if the drug improves the distance they can walk in six minutes.

What this could lead to

If successful, this could provide a more convenient once-daily inhaled treatment option to help people with pulmonary arterial hypertension walk farther and manage their condition.

What could go wrong

This is a phase 3 trial, but the drug is still experimental. It may not improve exercise capacity more than placebo, and side effects from the inhaled medication could occur.
