This is a multi-centre, multinational, open-label, single-dose acute hemodynamic study followed by randomized, double-blind, parallel-group, placebo controlled study. Eligible subjects will undergo an open-label, single-dose acute hemodynamic study with ACT-293987(NS-304) and 21 weeks of double-blind treatment during which subjects will receive either ACT-293987 (NS-304) or placebo b.i.d. Subjects who have completed the double-blind study can enter the open extension study (separate protocol) and receive administration of ACT-293987 (NS-304) if the subject wishes and the Investigator considers it appropriate.
This is a multi-centre, multinational, open-label, single-dose acute hemodynamic study followed by a randomized, double-blind, parallel-group, placebo controlled study. Eligible subjects will undergo screening followed by randomized allocation to treatment group for the double-blind study, followed in turn by immediate enrollment in an open-label, single-dose acute hemodynamic study with ACT-293987 (NS-304) and 21 weeks of double-blind treatment during which subjects will receive either ACT-293987 (NS-304)or placebo twice daily (b.i.d.). Subjects who have completed the double-blind study can enter the open extension study and receive administration of ACT-293987 (NS-304) (separate protocol)if the subject wishes and the investigator considers it appropriate.
Unblinding will occur on a subject-by-subject basis when the Week 17 data for the subject have been fixed.
Approximately 44 subjects are to be randomized in a ratio of 3:1 to the two treatment groups, ACT-293987 (NS-304) and placebo (33 subjects to ACT-293987 (NS-304) and 11 subjects to placebo).
Subjects will be randomized to the study following screening.
Allocation: Randomized, Intervention Model: Parallel Assignment

The AC-065A302 GRIPHON study is an event-driven Phase 3 study to demonstrate the effect of ACT-293987 on time to first clinical worsening in patients with pulmonary arterial hypertension.
Long-term, single-arm, multicenter, open-label extension, Phase 3 study, to evaluate the safety and tolerability of ACT-293987 in patients with PAH who participated in the double-blind stu...
The early detection of pulmonary arterial hypertension may help to improve prognosis of the disease. It is assumed that in the early stages of pulmonary arterial hypertension, pulmonary ar...
Exercise-induced increase of the pulmonary arterial pressure may be an early sign of pulmonary arterial hypertension. It has been shown that patients with normal pulmonary arterial pressur...
To assess the correlation between pulmonary IV-OCT and pulmonary IV-US measurements and standard PAH clinical measures of disease progression and the relative sensitivity of the techniques...
The role of decreased pulmonary arterial (PA) compliance (C), equivalent to increased PA stiffness (1/C) as a critical determinant of right ventricular dysfunction and prognosis has been emphasized in...
Pulmonary arterial hypertension is a multifactorial disease characterized by vasoconstriction, vascular remodeling, inflammation and thrombosis. Although an increasing number of research confirmed tha...
Pulmonary hypertension is common (25-90%) in chronic obstructive pulmonary diseases (COPDs). Severe pulmonary hypertension, however, is quite rare (1-3%). The term 'out of proportion' pulmonary hypert...
Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are rare diseases with a gradual decline in physical health. Adherence to treatment is crucial in these ...
Upregulation of the immune system is regarded to play an important role in the etiopathobiology of pulmonary arterial hypertension (PAH) and inoperable chronic thromboembolic pulmonary hypertension (C...
A malformation of the heart in which the embryonic common PULMONARY VEIN was not incorporated into the LEFT ATRIUM leaving behind a perforated fibromuscular membrane bisecting the left atrium, a three-atrium heart. The opening between the two left atrium sections determines the degree of obstruction to pulmonary venous return, pulmonary venous and pulmonary arterial hypertension.
A syndrome characterized by the clinical triad of advanced chronic liver disease, pulmonary vascular dilatations, and reduced arterial oxygenation (HYPOXEMIA) in the absence of intrinsic cardiopulmonary disease. This syndrome is common in the patients with LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL).
Hypertrophy and dilation of the RIGHT VENTRICLE of the heart that is caused by PULMONARY HYPERTENSION. This condition is often associated with pulmonary parenchymal or vascular diseases, such as CHRONIC OBSTRUCTIVE PULMONARY DISEASE and PULMONARY EMBOLISM.
Familial or idiopathic hypertension in the PULMONARY CIRCULATION which is not secondary to other disease.
A prostaglandin that is a powerful vasodilator and inhibits platelet aggregation. It is biosynthesized enzymatically from PROSTAGLANDIN ENDOPEROXIDES in human vascular tissue. The sodium salt has been also used to treat primary pulmonary hypertension (HYPERTENSION, PULMONARY).
Pulmonary arterial hypertension (PAH) is a chronic, life-threatening disorder characterized by abnormally high blood pressure in the arteries between the heart and lungs of affected individuals. Symptoms can range from mild breathles...
