Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective is to determine the effect of ambrisentan on exercise capacity in subjects with PAH.

ARIES-2 in Western and Eastern Europe, South America and Israel

Subjects in these randomized studies will receive one of two doses of ambrisentan or placebo. Inclusion is not based on a specified WHO functional classification. Rather, subjects with WHO Class I-IV symptoms are eligible if their 6-minute walk distance is 150-450 meters and they meet the study-specified hemodynamic criteria. Subjects with anorexigen or HIV infection related PAH are eligible but subjects with congenital heart disease and pediatric subjects are excluded. The study requires a historical cardiac catheterization and other diagnostic procedures.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Diagnosis of idiopathic PAH (formally known as PPH), or PAH associated with collagen vascular disease, anorexigen use, or HIV infection;
* Historical cardiac catheterization with the following hemodynamic criteria:

Mean pulmonary artery pressure greater than or equal to 25 mmHg; Pulmonary vascular resistance greater than 3 mmHg/L/min; Pulmonary capillary wedge pressure or left ventricular end diastolic pressure less than 15 mmHg;

* 6-minute walk distance of at least 150 meters, but no more than 450 meters;
* Total lung capacity greater than or equal to 70% and FEV1 greater than or equal to 65% of predicted normal;

Exclusion Criteria

* Portopulmonary hypertension;
* Subjects with PAH due to or associated with coronary artery disease, left heart disease, interstitial lung disease, chronic obstructive pulmonary disease, veno-occlusive disease, chronic thromboembolic disease, or sleep apnea;
* Bosentan (Tracleer®), sildenafil (Viagra®), or chronic prostanoid therapy within 4 weeks of screening;
* Serum ALT or AST lab value that is greater than 1.5 times the upper limit of normal;
* Contraindication to treatment with an endothelin receptor antagonist;
* Subject with cardiovascular, hepatic, renal, hematologic, gastrointestinal, immunologic, endocrine, metabolic, or central nervous system disease that may adversely affect the safety of the subject;
* Participation in a clinical study involving another investigational drug within 4 weeks of screening.
