Study Summary

This is a study to evaluate whether macitentan is an effective and safe treatment for patients with heart failure with preserved ejection fraction (HFpEF) and pulmonary vascular disease. The primary objective is to evaluate whether macitentan 10 mg reduces N-terminal pro-brain natriuretic peptide (NT-pro-BNP) as compared to placebo in these patients.

Primary Outcome

Percent of baseline NT-proBNP assessed at Week 24 was reported. Percent of baseline is calculated as the ratio of the Week 24 NT-proBNP value over baseline value, expressed in percentage. NT-proBNP is one of the best established cardiovascular response markers among all available surrogates in heart failure (HF).

Interventions

  • DRUG Placebo
  • DRUG Macitentan
