What is the purpose of this trial?

This trial tests a new inhaled treatment called mosliciguat for individuals with pulmonary hypertension linked to interstitial lung disease (ILD). The main goal is to determine if this treatment is safe and effective for those already using inhaled treprostinil. The trial seeks participants with confirmed pulmonary hypertension and a diagnosis of ILD, such as idiopathic interstitial pneumonia or chronic hypersensitivity pneumonitis, who can walk at least 100 meters in a 6-minute walk test. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of participants.

Is there any evidence suggesting that inhaled mosliciguat is likely to be safe for humans?

Research has shown that inhaled mosliciguat appears safe for people with pulmonary hypertension, a condition characterized by high blood pressure in the lungs. An earlier study found that mosliciguat was well tolerated by patients, causing no major problems. Most importantly, no serious safety issues emerged after just one dose. Another study supported these findings, indicating that patients handled mosliciguat easily.

While the treatment remains under investigation, these early results are promising. They suggest that mosliciguat could be a safe option for individuals with this condition. However, it is important to note that this information comes from early studies, and further research will provide a clearer understanding.12345

Why do researchers think this study treatment might be promising for pulmonary hypertension?

Unlike the standard treatments for pulmonary hypertension, which often involve oral medications or intravenous infusions, mosliciguat is unique because it's inhaled directly into the lungs. This new delivery method allows the treatment to act directly where it's needed, potentially improving effectiveness and reducing side effects. Additionally, mosliciguat targets a specific pathway in the body that helps relax blood vessels, which could lead to better management of the disease. Researchers are excited about mosliciguat because it offers a novel approach that could enhance patient outcomes and improve quality of life.

What evidence suggests that inhaled mosliciguat might be an effective treatment for pulmonary hypertension?

Research has shown that mosliciguat, which participants in this trial will receive, might help treat pulmonary hypertension, a condition characterized by high blood pressure in the lungs. Earlier studies found that mosliciguat lowers resistance in the lung's blood vessels, facilitating blood flow. It also helps open airways. Patients tolerated mosliciguat well, with no serious side effects reported, making it a promising option for managing pulmonary hypertension.13467

Are You a Good Fit for This Trial?

This trial is for individuals with pulmonary hypertension (high blood pressure in the lungs) that's linked to interstitial lung disease—a condition where scar tissue forms in the lungs. Participants should already be using inhaled treprostinil, a medication for their condition.
