A Phase III Extension Study of Udenafil in Adolescents With Single Ventricle Physiology After Fontan Palliation

This study is a 12-month (52 week) safety extension study to supplement the FUEL Phase III
clinical trial to provide safety information regarding the long-term use of udenafil in
adolescents with single ventricle congenital heart disease.

This will be an open-label extension study. All enrolled subjects will be provided with
udenafil for the duration of the study. Subjects completing the Phase III FUEL study will be
eligible for recruitment. Additional subjects will be recruited as needed to ensure a minimum
of 300 total subjects enroll. Safety, pharmacodynamic and quality of life data will be
collected and analyzed.

Inclusion Criteria:

1. Males and females with Fontan physiology who participated in the FUEL trial or, if
they did not participate in FUEL, those who are 12 to less than 19 years of age at
enrollment.

2. Participant consent or parental/guardian consent and participant assent.

3. Participant fluent in English, Spanish, or Korean.

4. Current anti-platelet or anticoagulant therapy.

Exclusion Criteria:

1. Height < 132 cm.

2. Weight < 40 kg.

3. Hospitalization for acute decompensated heart failure within the last 12 months.

4. Current intravenous inotropic drugs.

5. Undergoing evaluation for heart transplantation or listed for transplantation.

6. Diagnosis of active protein losing enteropathy or plastic bronchitis within the last
three years, or a history of liver cirrhosis.

7. Known Fontan baffle obstruction, branch pulmonary artery stenosis, or pulmonary vein
stenosis resulting in a mean gradient of > 4 mm Hg between the regions proximal and
distal to the obstruction as measured by either catheterization or echocardiography.

8. Single lung physiology.

9. Maximal VO2 less than 50% of predicted for age and gender at enrollment.

10. Severe ventricular dysfunction assessed qualitatively by clinical echocardiography
within six months prior to enrollment.

11. Severe valvar regurgitation, ventricular outflow obstruction, or aortic arch
obstruction assessed by clinical echocardiography within six months prior to
enrollment.

12. Significant renal, hepatic, gastrointestinal or biliary disorders that could impair
absorption, metabolism or excretion of orally administered medications.

13. Inability to complete exercise testing at baseline screening.

14. History of PDE-5 inhibitor use (with the exception of FUEL participation) within 3
months before study onset.

15. Use of any other drug to treat pulmonary hypertension within 3 months before study
onset.

16. Known intolerance to oral udenafil.

17. Frequent use of medications or other substances that inhibit or induce CYP3A4.

18. Current use of alpha-blockers or nitrates.

19. Ongoing or planned participation in another research protocol that would either
prevent successful completion of planned study testing or invalidate its results.

20. Noncardiac medical, psychiatric, and/or social disorder that would prevent successful
completion of planned study testing or would invalidate its results.

21. Cardiac care, ongoing or planned, at a non-study center that would impede study
completion.

22. For females: Pregnancy at the time of screening, pregnancy planned before study
completion, or refusal to use an acceptable method of contraception for study
duration.

23. Unable to abstain or limit intake of grapefruit juice during the duration of the
trial.

24. Refusal to provide written informed consent/assent.

25. In the opinion of the primary care physician, the subject is likely to be
non-compliant with the study protocol.

26. History of clinically significant thromboembolic event, as adjudicated by study
Investigators.
