About this trial

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

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Idiopathic PAH

Heritable PAH

Drug/toxin-induced PAH

Connective tissue disease (CTD)-associated PAH

Disqualifiers

Diagnosis of PH WHO Groups 2, 3, 4, or 5, or subtypes of PH WHO Group 1 other than described in inclusion criterion 2 (eg, human immunodeficiency virus (HIV), complex congenital heart disease-associated PAH, portal hypertension-associated PAH, pulmonary veno-occlusive disease, Schistosomiasis associated PAH).

Clinically significant left heart disease, including left-sided valvular disease, left ventricular systolic or diastolic dysfunction, echocardiographic findings suggestive of post-capillary pulmonary hypertension, unstable ischemic heart disease, or unstable arrhythmias.

Evidence of airflow obstruction defined by forced expiratory volume in 1 second (FEV1) per forced vital capacity (FVC) <0.7.

Evidence of significant restrictive lung disease as evidenced by FVC <70% predicted normal.
