Secondary Outcome Measures
Change From Baseline to Week 24 in Borg Dyspnea Index
Change from Baseline to Week 24 in Borg Dyspnea Index. The Borg Dyspnea Index of Perceived Exertion Scores range from 0 to 10. Best and Worst values are: 0 (Best) to 10 (Worst). Scales are described as rating of breathlessness and its description: 0= none; 0.5= very,very slight (just noticeable); 1= very slight; 2=slight; 3= moderate; 4= somewhat severe; 5= severe; 6 (in between severe and very severe); 7= very severe; 8 (in between very, very severe and maximum); 9= very, very severe; and 10= maximum.

Percent Change From Baseline to Week 48 in BNP
Change From Baseline to Week 24 in WHO Functional Class
Change from baseline in World Health Organization functional class (WHO) at Week 24 is the incidence of participants that improved, had no change, or worsened. WHO categories are 1 to 4 with the worse category at 4. Improvement = a category change from baseline of <= -1: change of -3 (eg, WHO from 4 to 1), change of -2 (eg, WHO from 3 to 1), change of -1 (eg, WHO from 2 to 1). Inversely, participants worsening are those with a category change from baseline of at least +1. No change in WHO functional class represents the percentage of participants with a change in category from baseline of 0.
Change From Baseline to Week 48 in WHO Functional Class
Change from baseline in WHO at Week 48 is expressed as the incidence of participants that improved, had no change or worsened. WHO categories range from 1 to 4 with the worse category at 4. Improvement = a category change from baseline of <= -1: change of -3 (eg, WHO from 4 to 1), change of -2 (eg, WHO from 3 to 1), change of -1 (eg, WHO from 2 to 1). Inversely, participants worsening are those with a category change from baseline of at least +1. No change in WHO functional class represents the percentage of participants with a change in category from baseline of 0.
Change From Baseline to Week 24 in SF-36 Health Survey Physical Functioning Scale
Change from baseline to Week 24 in the SF-36 health survey physical functioning scale. 10 activities rated by health limitations using 3 categories (1= Yes, limited a lot; 2= Yes, limited a little; and 3= No, not limited at all). The best score is 3 and the worst score is 1. Scores are transformed by subtracting the unit by the lowest raw score and dividing by the raw score range. The scores are then standardized with the 1998 General United States (US) population mean and standard deviation (SD). Finally, the scores are transformed to the norm-based scoring with a mean of 50 and SD of 10.

5. Study Description
Brief Summary
The primary objective of this study was to evaluate the safety and efficacy of ambrisentan in a broad population of participants with pulmonary hypertension (PH). Secondary objectives of this study were to evaluate the effects of ambrisentan on other clinical measures of pulmonary arterial hypertension (PAH), long-term treatment success, and survival.
Detailed Description
This study was to enroll up to 200 participants with PH due to the following etiologies: 1) PAH including idiopathic and familial PAH and PAH associated with collagen vascular disease, congenital systemic-to-pulmonary shunts (including Eisenmenger's syndrome), human immunodeficiency virus (HIV) infection, drugs and toxins, thyroid disorders, glycogen storage disease, Gaucher disease, hemoglobinopathies, and splenectomy (WHO Group 1); 2) PH associated with lung diseases and/or hypoxemia, including chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD), sleep-disordered breathing, and alveolar hypoventilation disorders (WHO Group 3); 3) PH due to proximal or distal chronic thromboembolic obstruction (WHO Group 4); and 4) PH due to sarcoidosis (WHO Group 5). Participants with left heart disease or left heart failure were excluded (WHO Group 2). Participants could be receiving prostacyclin or sildenafil therapy at baseline, and participants who previously discontinued either bosentan, sitaxsentan, or both, due to liver function test abnormalities were eligible.
