United Therapeutics Corp. is conducting an extension study titled ‘An Open-label Extension Study of Inhaled Treprostinil in Subjects With Idiopathic Pulmonary Fibrosis.’ The study aims to evaluate the long-term safety and tolerability of inhaled treprostinil in patients with idiopathic pulmonary fibrosis (IPF), a chronic and progressive lung disease. This study is significant as it seeks to provide insights into a potential treatment option for IPF, which currently has limited therapeutic solutions.
The intervention being tested is inhaled treprostinil, delivered via an ultrasonic nebulizer. This drug is intended to improve lung function and overall health outcomes in IPF patients by being administered four times daily.
This Phase 3 study follows an open-label extension design, meaning all participants receive the treatment without a placebo group for comparison. The primary purpose of the study is treatment-focused, with no masking involved, allowing researchers to directly observe the effects of the drug.
The study began on September 6, 2022, and is currently enrolling by invitation. The last update was submitted on July 25, 2025. These dates are crucial as they indicate the study’s progress and ongoing nature, which is essential for stakeholders tracking the development of new treatments.
The market implications of this study are significant for United Therapeutics, as positive results could enhance the company’s stock performance and investor confidence. The development of a successful IPF treatment could position United Therapeutics favorably against competitors in the respiratory disease treatment market.
The study is ongoing, with further details available on the ClinicalTrials portal.
