E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate the safety of oral Bosentan therapy in patients with a Fontan circulation. The primary endpoint will be lack of clinically significant adverse events over the 6 month follow up period. Specifically we will look for evidence of hepatic dysfunction, haematological dysfunction and renal dysfunction. Patients will be assessed for symtomatic deterioration. |
|
E.2.2 | Secondary objectives of the trial |
Improvement in cardiovascular performance as measured by exercise test, cardiac MRI, Borg dyspnoea index and echo. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Age 18 or over with a Fontan circulation and NYHA II or greater symptoms of heart failure. The patient has no other significant illness that would preclude them from completing the study. Patients must be available to complete follow up. Patients must be able to provide informed consent. Patients must agree not to become pregnant during the study.
|
|
E.4 | Principal exclusion criteria |
Lack of sinus rhythm at enrolment Permanent pacemaker in situ Inability to complete exercise testing Pre-existent liver disease as described in the bosentan SmPC1 Significant haematogical abnormality or renal dysfunction. Current use of any prostanoid, other endothelion receptor antagonist or pulmonary vasodilator therapy, such as PDE V inhibitors i.e. sildenafil or similar. Pregnancy Current enrolment in a clinical trial Any contraindication according to the bosentan SmPC1
