[11] 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. [12] History of atrial septostomy or Potts Shunt within 3 months before administration of study drug. [13] Unrepaired congenital heart disease except associated with an atrial-ventricular septal defect. [14] Concurrent PDE-5 inhibitor therapy (sildenafil or vardenafil) or has received PDE-5 inhibitor therapy within 24 hours prior to the first study drug dosing (baseline visit). [15] Concurrent therapy with prostacyclin or its analogues. [16] Commence or discontinue a conventional PAH medication including but not restricted to: calcium channel blockers, diuretics, anti-coagulants, digoxin, and oxygen therapy within 4 weeks prior to screening. [17] Have a history of angina pectoris or other condition that was treated with long- or short acting nitrates within 12 weeks before administration of study drug. [18] Currently receiving treatment with doxazosin, nitrates or cancer therapy. [19] Current treatment with antiretroviral therapy (protease inhibitor), systemic ketoconazole or systemic itraconazole.

| Measure | Time frame |
|---|---|
| Main Objective: Main objective of the trial is to characterize the pharmacokinetics (PK) of tadalafil in a pediatric population with pulmonary arterial hypertension (PAH) to establish an appropriate dose range for further clinical research.;Secondary Objective: Secondary Objectives: - To assess the tolerability and safety of tadalafil in a pediatric population with PAH. - To compare tadalafil PK profile in a pediatric population with historical adult data from Study H6D-MC-LVGY. - To assess the palatability of the tadalafil suspension. Open-label Extension Objective (Period 2): - To evaluate long-term safety while providing continued access to tadalafil for pediatric patients completing Period 1. - To evaluate clinical worsening (CW), defined as any of the following: death, lung or heart transplantation, atrial septostomy or potts shunt, hospitalization due to worsening PAH, new onset syncope, initiation of new PAH therapy, worsening of World Health Organization (WHO) functional class by 1 or more, and decreasing of 20% in the 6-minute walk (6MW) test (for those patients ?7 years of age).;Primary end point(s): Safety: Safety will be evaluated using spontaneously reported adverse events, clinical laboratory data, vital signs, physical examinations, and centralized 12-lead electrocardiograms (ECGs) as outlined in the schedule of events. Bioanalytical: Plasma concentrations of tadalafil. Pharmacokinetic/Pharmacodynamic: The pharmacokinetic parameters estimated during analysis will include area under the concentration-time curve (AUC), maximal concentration (Cmax), time of Cmax (tmax), apparent clearance (CL/F), apparent volume of distribution (Vz/F), and terminal half-life (t½), as appropriate.;Timepoint(s) of evaluation of this end point: Throughout the duration of the study | — |
