This clinical trial is focused on studying the effects of a treatment for Pulmonary Hypertension associated with Interstitial Lung Disease. The treatment being tested is called Treprostinil Palmitil Inhalation Powder, also known by its code name INS1009. This medication is administered as an inhalation powder, which means it is breathed in through a device designed for this purpose. The study also involves a placebo, which is a substance with no active medication, to compare the effects of the treatment.
The purpose of the study is to evaluate the safety and tolerability of long-term use of Treprostinil Palmitil Inhalation Powder in participants with Pulmonary Hypertension associated with Interstitial Lung Disease. Participants who have completed previous related studies are eligible to join this extension study. The study will monitor participants over a period of time to observe any side effects and to assess how well the treatment is tolerated. Participants will be asked to use the inhalation powder regularly and attend follow-up visits to track their progress.
Throughout the study, various health measurements will be taken to assess the effectiveness of the treatment. These include tests to measure lung function and exercise capacity, as well as blood tests to check for specific markers related to the disease. The study aims to provide valuable information on the long-term use of Treprostinil Palmitil Inhalation Powder, which could help improve treatment options for people with Pulmonary Hypertension associated with Interstitial Lung Disease.
