Exclusion Criteria

1. Premature discontinuation of study treatment in the main study (SERENADE / AC-055G202, EudraCT number 2016-003653-15) due to an adverse event related to:
a. Edema or fluid retention
b. Worsening of heart failure

2. Liver aminotransferase elevations outside of normal range at the enrollment visit fulfilling the following criteria:

b. associated increase in total bilirubin outside of normal range
3. Treatment with the following forbidden medications within 1 month prior to the enrollment visit:
