Efficacy and Safety Study of Treprostinil Palmitil Inhalation Powder (TPIP) in Participants With Pulmonary Hypertension Associated With Interstitial Lung Disease (PH-ILD)

The primary objective of this study is to evaluate the effect of 24-weeks of once daily treatment with TPIP versus placebo on exercise capacity in adults with PH-ILD.

• * Diagnosis of PH World Health Organisation (WHO) Group 3 associated with ILD [including but not limited to idiopathic interstitial pneumonia (IIP), chronic hypersensitivity pneumonitis (HSP), connective tissue disease-associated interstitial lung disease (CTD-ILD), combined pulmonary fibrosis and emphysema (CPFE)]. * Confirmation of fibrotic interstitial lung disease by centrally overread computed tomography (CT) scan performed at Screening or within prior 12 months. * PH confirmed by right heart catheterization (RHC) at Screening or within 12 months prior to Screening, with the following hemodynamic findings: * Mean pulmonary arterial pressure (mPAP) >20 millimetre of mercury (mmHg) and * Pulmonary capillary wedge pressure (PCWP) of ≤15 mmHg and * Pulmonary vascular resistance (PVR) ≥4 wood units (WU). * 6 Minute walking distance (6MWD) ≥100 and ≤500 meters at two 6MWTs at Screening performed at least 4 hours apart, with the difference between the 2 distances ≤15%. * Participants receiving chronic medication for underlying disease (e.g., antifibrotic, immunomodulators, immunosuppressants, etc.) and/or phosphodiesterase 5 (PDE5) inhibitors, should be on this treatment for ≥90 days and on a stable dose for ≥30 days prior to Screening. * Capable of giving signed informed consent as described in Section 10.1.5 which includes compliance with the requirements…
