Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
Currently have a diagnosis of PAH that is either:
- idiopathic (including hereditary), related to collagen vascular disease, related to anorexigen use, associated with surgical repair, of at least 6 month duration, of a congenital systemic to pulmonary shunt (for example, atrial septal defect, ventricular septal defect, patent ductus arteriosus).
- Have a history of the diagnosis of PAH established by a resting mean pulmonary artery pressure ≥25 mm Hg, pulmonary artery wedge pressure ≤15 mm Hg, and a pulmonary vascular resistance (PVR) ≥3 Wood units via right heart catheterization. In the event that a pulmonary artery wedge pressure is unable to be obtained during right heart catheterization, participants with a left ventricular end diastolic pressure <15 mm Hg, with normal left heart function, and absence of mitral stenosis on echocardiography can be eligible for enrollment
- Have a World Health Organization (WHO) functional class value of I, II or III at the time of enrollment
Exclusion Criteria:
- Have pulmonary hypertension related to conditions other than specified above, including but not limited to chronic thromboembolic disease, portal pulmonary hypertension, left-sided heart disease or lung disease and hypoxia
History of left-sided heart disease, including any of the following:
- clinically significant (pulmonary artery occlusion pressure [PAOP] 15 to 18 mm Hg) aortic or mitral valve disease (that is, aortic stenosis, aortic insufficiency, mitral stenosis, moderate or greater mitral regurgitation)
- pericardial constriction
- restrictive or congestive cardiomyopathy
- left ventricular ejection fraction <40% by multigated radionucleotide angiogram (MUGA), angiography, or echocardiography
- left ventricular shortening fraction <22% by echocardiography
- life-threatening cardiac arrhythmias
- symptomatic coronary artery disease within 5 years of study entry as determined by the physician
- History of atrial septostomy or Potts Shunt within 3 months before administration of study drug
- Unrepaired congenital heart disease

Percentage of Participants With Clinical Worsening
Time Frame: Baseline Up to 27 Months
|
Clinical worsening was defined as any of the following: death, lung or heart transplantation, atrial septostomy or Potts' shunt, hospitalization for Pulmonary Arterial Hypertension (PAH) progression, new onset syncope, initiation of new PAH therapy (including increase in the dose of existing PAH specific concomitant therapy, such as endothelin receptor agonist or beraprost medication), or increase of 1 or more in World Health Organization(WHO) Functional Class (except for participants already in Class IV; only for participants unable to perform the 6 minute walk (6MW) test; worsening of WHO functional class by 1 or more for participants who can perform a 6 minute walk (6MW) test and who have a decrease of ≥ 20% in the 6 minute walk distance (for those participants who are ≥6 years of age).

Number of Participants With Palatability of the Tadalafil Suspension
Time Frame: Day 35 (high dose)
|
The Taste Assessment Questionnaire (TAQ) questions were: TAQRES1: Please rate the bitterness level. TAQRES2: Please rate the sweetness level. TAQRES3: Please rate the aftertaste. TAQRES4: Please rate the overall acceptability of the taste for daily use. |
