New inhaled drug aims to ease lung scarring and heart strain
NCT ID NCT06635850
First seen Jun 24, 2026 · Last updated Sep 11, 2026 · Updated 4 times
Summary
This Phase 2 trial tests an inhaled medication called mosliciguat in 135 people who have both lung scarring (interstitial lung disease) and high blood pressure in the lungs. Participants are randomly assigned to receive either the drug or a placebo for 16 weeks. The study measures changes in blood vessel resistance in the lungs and how far people can walk in six minutes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- mosliciguat (inhaled)
- What this could lead to
- If successful, this could lead to a new inhaled treatment to improve blood flow and exercise ability in people with lung scarring and high blood pressure in the lungs.
- What could go wrong
- This is an early Phase 2 trial with only 135 people, so results may not confirm benefit. The drug may cause side effects or not work better than placebo.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Participants willing and able to provide informed consent * Participants with diagnosis of Interstitial Lung Disease (ILD). Diagnosis will be confirmed by a high-resolution computerized tomography (HR-CT) scan showing diffuse parenchymal disease. Eligible diagnosed diseases include one of the following: 1. Idiopathic interstitial pneumonia (IIP) 2. Chronic hypersensitivity pneumonitis 3. ILD associated with connective tissue disease (CTD) with a forced vital capacity (FVC) \< 70% of predicted * Confirmed pulmonary hypertension (PH) by right heart catheterization (RHC). * Ability to perform 6MWT ≥100 meters. Exclusion Criteria: * Diagnosis of WHO PH Group 1 (eg. pulmonary arterial hypertension), Group 2 (related to left-heart dysfunction), Group 4 (eg, chronic thromboembolic pulmonary hypertension), or Group 5 (eg, unclassified). * Exacerbation of underlying lung disease requiring augmentation of therapy or emergent hospitalization within 28 days prior to randomization. * Initiation of pulmonary rehabilitation within 28 days prior to randomization. * Receiving \>10 L/min of oxygen supplementation by any mode of delivery at rest at Baseline. * History or intolerance to or lack of efficacy with mosliciguat or sGC stimulators or activators. * Receipt of investigational, or experimental therapy within 42 days OR 5 half-lives prior to randomization. Note: Other inclusion and exclusion criteria may apply.
