Primary Outcome(s)
|
Main Objective: The objective of this study is to evaluate the long-term safety of ambrisentan in patients with PAH and to explore the long-term safety of the initiation of prostacyclin therapy in PAH patients receiving ambrisentan.
|
Primary end point(s): The primary endpoint of this study is the incidence and severity of adverse events associated with long-term exposure to ambrisentan in subjects with PAH.
The secondary endpoints include:
1. A change from baseline in the: • Exercise capacity as measured by distance traveled in the six-minute walk test; • Borg Dyspnea Index immediately following exercise; • WHO Functional Class; • SF-36™ Health Survey;
2. Clinical worsening of PAH, as defined by the time from initiation of active treatment to the first occurrence of death, lung transplantation, hospitalization for PAH, atrial septostomy, the addition of approved prostanoid therapy, or study withdrawal due to the addition of other clinically approved PAH therapeutic agents;
3. Failure-free treatment status, as defined by the time from initiation of active treatment to the first occurrence of death, lung transplantation, the addition of approved prostanoid therapy, or study withdrawal due to the addition of other clinically approved PAH therapeutic agents;
4. Long-term survival, as defined by the time from initiation of active treatment to death, compared to predicted NIH estimates.
|
Secondary Objective: In addition, this study will continue the efficacy assessments of the previous studies, examine long-term ambrisentan treatment success, and compare long-term survival of subjects treated with ambrisentan to the NIH registry of patients with PAH.
