Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with PH-ILD confirmed by HR-CT and right heart catheterization, able to walk at least 100 meters in the 6-minute walk test, and able to provide informed consent.

Probably not a fit

Patients with PH not related to ILD, those unable to tolerate inhaled therapy, or those with recent exacerbations or high-flow oxygen requirements may have limited benefit.

What this trial studies

This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled trial evaluating the safety and efficacy of inhaled mosliciguat in participants with pulmonary hypertension associated with interstitial lung disease. The study has a 24-week blinded period followed by an extension in which all participants may receive mosliciguat. Participants are randomized to mosliciguat or placebo during the blinded period, and those who complete it may enter the extension where mosliciguat is given to all. The trial uses a dry powder inhaler and assesses outcomes such as functional capacity and other clinical measures.

Why it matters

Potential benefit: If successful, participants may experience improved symptoms and exercise capacity related to PH-ILD and potential slowing of disease progression.

How similar studies have gone: Previous studies in related pulmonary hypertension populations have shown signals of benefit with vasodilator inhaled therapies, but results in PH-ILD are still being established.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Participants willing and able to provide informed consent.
* Participants with diagnosis of pulmonary hypertension (PH) associated with interstitial lung disease (ILD). Diagnosis will be confirmed by a high-resolution computerized tomography (HR-CT) scan showing diffuse parenchymal disease. Eligible diagnosed disease include:

  1. Idiopathic interstitial pneumonia (IIP)
  2. Chronic Hypersensitivity pneumonitis
  3. ILD associated connective tissue disease (CTD)
* Confirmed pulmonary hypertension by right heart catheterization (RHC).
* Ability to perform 6-minute walk distance ≥100 meters.

Exclusion Criteria:

* Diagnosis of PH Group 1 (eg, pulmonary arterial hypertension), Group 2 (related to left heart disease), Group 4 (eg, chronic thromboembolic pulmonary hypertension), or Group 5 (eg, unclassified).
* Exacerbation of underlying lung disease requiring change in therapy or hospitalization within 28 days prior to randomization
* Receiving \>10 L/min oxygen supplementation by any mode of delivery at rest
* History of intolerance to mosliciguat, or sGC stimulators or activators.
* Initiation of pulmonary rehabilitation or ongoing acute phase of rehabilitation within 28 days prior to randomization.
* Receipt of investigational or interventional therapy within 42 days OR 5 half-lives (whichever is longer) prior to randomization.
