Arm Intervention/treatment
Active Comparator: 20 mg tadalafil
20 milligram (mg) tadalafil taken once a day
 Drug: tadalafil
20 milligram (mg) tablet, taken by mouth once a day for 52 weeks for the phase 1 portion. Open label phase includes 40 mg tablet taken by mouth once a day until the sponsor concludes the study or tadalafil becomes commercially available for the treatment of Pulmonary Arterial Hypertension (PAH).

  • Cialis
  • IC351
Active Comparator: 40 mg tadalafil
40 mg tadalafil tablet taken once a day
 Drug: tadalafil
40 mg tablet taken by mouth once a day for 52 weeks in phase 1. Open label phase includes 40 mg tablet taken by mouth once a day until the sponsor concludes the study or tadalafil becomes commercially available for the treatment of PAH.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Participants With Adverse Events (AEs) [ Time Frame: Baseline (Double-Blind Period) up to Week 243 (End of Open-Label Period) ]
    A summary of serious and all other non-serious AEs, which include adverse events reported for laboratory tests and vital signs, is located in the Reported Adverse Event module.


Secondary Outcome Measures :
  1. 6-Minute Walk Distance (6MWD) at Baseline and Weeks 16, 28, 40 and 52 [ Time Frame: Baseline and Weeks 16, 28, 40 and 52 ]
    6MWD measured the distance a participant was able to walk unassisted in 6 minutes.

  2. Borg Dyspnea Assessment at Baseline and Weeks 16, 28, 40 and 52 [ Time Frame: Baseline and Weeks 16, 28, 40 and 52 ]
    Borg dyspnea score is a participant rated measure of their greatest degree of shortness of breath during exertion (6-minute walk test). Score ranged from 0 (nothing at all) to 10 (very, very severe [maximal]).

  3. Probability of No Pulmonary Arterial Hypertension (PAH) Deterioration at Weeks 16, 28, 40 and up to 52 [ Time Frame: Baseline and Weeks 16, 28, 40 and 52 ]
    World Health Organization Functional Classification Assessment (WHO FC) is a method of classifying disease severity in PAH. The classes are: Class I: pulmonary hypertension (PH) but without resulting limitation of physical activity, Class II: PH resulting in slight limitation of physical activity, Class III: PH resulting in marked limitation of physical activity, Class IV: PH with inability to carry out any physical activity without symptoms. Deterioration of WHO FC is defined as moving to a higher WHO FC within one visit. Results are presented as Kaplan-Meier estimates (% probability) of remaining free from WHO FC deterioration after a given time.
