 (submitted: February 10, 2014)
Overall Survival (OS) [ Time Frame: every 3 months up to month 96 ]
Time in weeks from the start of study treatment to date of death due to any cause. Death will be determined from adverse event data (where outcome was death) or from follow-up contact data (where the participant current status was death).

Current Secondary Outcome Measures  ICMJE
 (submitted: February 10, 2014)
  • Time to first clinical worsening (TTCW) event [ Time Frame: every 3 months up to month 96 ]
    TTCW defined as the number of days between first dose of study drug and the occurrence of a predefined clinical worsening event. Predefined clinical worsening events include: death, hospitalization due to worsening PAH or disease progression
  • 6 Minute Walk Distance (6MWD) at Months 6 & 12 [ Time Frame: Months 6 & 12 ]
    6MWD is the distance a participant can walk in 6 minutes.

Descriptive Information
Brief Title  ICMJE Effects of Oral Sildenafil on Mortality in Adults With PAH
Official Title  ICMJE A MULTINATIONAL, MULTICENTER STUDY TO ASSESS THE EFFECTS OF ORAL SILDENAFIL ON MORTALITY IN ADULTS WITH PULMONARY ARTERIAL HYPERTENSION (PAH)
Brief Summary This is a blinded study in adult patients with PAH evaluating the relative effects of sildenafil on mortality when administered at the three doses (80 mg, 20 mg or 5 mg, all three times per day [TID]). In addition, the relative effects on clinical worsening and 6-minute walking distance (6MWD) will be assessed.
