. Women of childbearing potential must:
- Have a negative serum pregnancy test prior to first intake of OL study drug, and,
- Agree to perform monthly pregnancy tests up to the end of the safety follow up (S-FU) period, and,
- use reliable methods of contraception from enrollment up to at least 30 days after study treatment discontinuation |
|
E.4 | Principal exclusion criteria |
. Clinical worsening leading to medical interventions including reoperation of Fontan circulation (Fontan take-down) during the enrollment period.
. Systolic blood pressure < 90 mmHg (< 85 mmHg for subjects < 18 years old and < 150 cm of height) at rest.
. Criteria related to macitentan use
. Any known factor or disease that may interfere with treatment compliance or full participation in the study. |
