Pharmacokinetic/Pharmacodynamic Study of Udenafil in Adolescents
brief summary
To determine the pharmacokinetic profile and safety of udenafil in adolescents with Fontan physiology and to assess the short-term pharmacodynamic effect of udenafil on pharmacodynamic measures of exercise capacity, ventricular performance, and vascular function.
detailed description
A dose escalation trial to determine the pharmacokinetics, safety and tolerance of udenafil in male and female adolescent subjects with single ventricle physiology that that have undergone the Fontan surgical procedure. Pharmacodynamic data will also be collected to evaluate the effect of udenafil on acute exercise performance, peripheral vascular function and indices of myocardial performance. Five udenafil cohorts will be evaluated in additional to one drug free cohort
official title
A Phase I/II Dose Escalation Trial of Udenafil in Adolescents With Single Ventricle Physiology After Fontan Palliation
