Full Study Name

Fontan Udenafil Exercise Longitudinal Assessment Trial (IRB no. 44590)

Summary

This study focuses on children who have had a Fontan operation (a procedure used in patients with only one functional ventricle). This study is designed to evaluate the effect of six months of treatment with an investigational drug called udenafil on exercise capacity in adolescents with Fontan physiology. Researchers will compare udenafil to placebo (inactive substance) to better understand the effect udenafil has on young patients who have had a Fontan surgery. Participants will receive either udenafil (87.5 mg twice daily) or placebo.
