E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to assess the efficacy of the addition of inhaled iloprost vs. placebo in patients with PAH receiving sildenafil. The primary measure will be the change in 6-Minute Walk Distance 6-MWD from baseline, measured after inhalation, following 16 weeks of combination therapy with inhaled iloprost administered 6 times per day and sildenafil vs. inhaled placebo plus sildenafil. |
|
E.2.2 | Secondary objectives of the trial |
Secondary efficacy objectives include the following in order of priority Change from baseline in 6-MWD measured after inhalation at Week 16 of combination therapy with inhaled iloprost administered 4 times per day and sildenafil vs. placebo plus sildenafil Change from baseline in New York Heart Association NYHA /World Health Organization WHO class assessed at Week 16 of combination therapy with iloprost administered by inhalation 6 times per day and sildenafil vs. placebo inhalation plus sildenafil Time to clinical worsening during combination therapy with iloprost administered by inhalation 6 times per day plus sildenafil vs. placebo inhalation plus sildenafil, where clinical worsening is defined by death due to PAH, hospitalization for worsening PAH, any early discontinuation from study due to worsening PAH, initiation of additional PAH-specific therapy such as systemic prostanoids , or performance of lung or heartlung transplant |

|
E.4 | Principal exclusion criteria |
Exclusion Criteria Any treatment for PAH with prostacyclins, prostacyclin analogues, PDE-5 inhibitors other than sildenafil, or endothelin-1 antagonists within the past 12 weeks. Pulmonary hypertension due to conditions other than as stated in inclusion criteria. Additional PAH medications added within the past 12 weeks |

E.5 End points |
E.5.1 | Primary end point(s) |
Primary efficacy measure Change from baseline in 6-MWD measured at Week 16 postinhalation of the randomized study following combination therapy with iloprost when administered by inhalation 6 times per day and sildenafil Group A vs. placebo inhalation and sildenafil Group C |
