Pulmonary Arterial Hypertension | Drug: Tadalafil- Tablet | Phase 1 Phase 2 |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 24 participants |
Intervention Model: | Single Group Assignment |
Masking: | None (Open Label) |
Primary Purpose: | Treatment |
Official Title: | A Multiple Ascending Dose Study of Tadalafil to Assess the Pharmacokinetics and Safety in a Pediatric Population With Pulmonary Arterial Hypertension |
Study Start Date : | July 2012 |
Actual Primary Completion Date : | April 2017 |
Estimated Study Completion Date : | May 2019 |

Arm | Intervention/treatment |
---|---|
Experimental: tadalafil
The dose of tadalafil will be escalated from low to high for each participant based on body weight for 5 weeks at low dose and 5 weeks at high dose.
|
Drug: Tadalafil- Tablet
Tadalafil tablets: 2.5 mg and 5 mg, 10 mg, 20 mg and 40 mg (two 20 mg) administered orally, once daily in the heavy weight cohort >=40 kg and middle weight cohort >=25 kg to <40 kg Drug: Tadalafil - Oral suspension Tadalafil Oral suspension: 1 mg, 5 mg administered orally, once daily in the light weight cohort <25 kg |
- Pharmacokinetics: Area under the concentration time curve for tadalafil [ Time Frame: Period 1: pre dose up to 24 hours post dose ]
- Pharmacokinetics: Maximum plasma concentration for tadalafil [ Time Frame: Period 1: pre dose up to 24 hours post dose ]
- Change from baseline to endpoint in World Health Organization (WHO) functional class [ Time Frame: Period 1: baseline, 10 weeks ]
- Change from baseline to endpoint in 6 minute walk distance for participants greater than or equal to 7 years of age [ Time Frame: Period 1: baseline, 10 weeks ]
- Percent increase from baseline to endpoint in N Terminal-Pro Brain Natriuretic Peptide (NT-Pro-BNP) [ Time Frame: Period 1: baseline and 10 weeks ]
- Percentage of participants with clinical worsening [ Time Frame: Period 2: baseline up to 2 years ]

Ages Eligible for Study: | 6 Months to 17 Years (Child) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
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
