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.
Mean pulmonary arterial pressure (mPAP) >20 millimetre of mercury (mmHg) and
Pulmonary capillary wedge pressure (PCWP) of ≤15 mmHg and
Diagnosis of Pulmonary Hypertension WHO Groups 1, 2, 4, or 5, or subtypes of PH WHO Group 3 other than interstitial lung disease.
Primary diagnosis of chronic obstructive pulmonary disease (COPD) and/or forced expiratory volume in 1 second (FEV1)/FVC <0.7 (based on screening or historical spirometry within the prior 6 months).
evidence of clinically significant left-sided valvular heart disease,
left ventricular failure with left ventricular ejection fraction (LVEF) <45%, or diagnosis of heart failure with preserved ejection fraction (HFpEF)
