Brief 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.

Drug Information available for: Macitentan

Arm Intervention/treatment
Active Comparator: Macitentan
Subjects randomized to the macitentan arm receives one tablet of macitentan 10 mg every day for at least 24 to maximum 52 weeks.
Drug: Macitentan
macitentan 10 mg; film-coated tablet; oral use
Other Name: ACT-064992

Placebo Comparator: Placebo
Subjects randomized to the placebo arm received one tablet of placebo every day for at least 24 to maximum 52 weeks.
Drug: Placebo
film-coated tablet (identical to the macitentan tablet); oral use

Primary Outcome Measures :
  1. Change in NT-proBNP (Percent of Baseline Assessed at Week 24) [ Time Frame: Baseline and Week 24 ]
    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). Changes in this marker may reflect reduction in cardiac load and left ventricular wall stress; reductions in NT-proBNP have been associated with improved outcomes in HF.

Secondary Outcome Measures :
  1. Change From Baseline to Week 24 in the Clinical Summary Score (as Assessed by the Kansas City Cardiomyopathy Questionnaire [KCCQ]) [ Time Frame: Baseline and Week 24 ]
    The clinical summary score (mean of physical limitation and total symptoms score) of the KCCQ is expressed as change from baseline to Week 24.

  2. Change from baseline to Week 24 in accelerometer-assessed physical activity [ Time Frame: Baseline and Week 24 ]
    Physical activity is assessed by accelerometer as the proportion of time spent in light to vigorous physical activity based on a threshold of >100 activity counts per minute and expressed as change from baseline to Week 24.

  3. Time to worsening heart failure (WHF) event over 52 weeks [ Time Frame: Baseline to Week 52 ]
    A WHF event includes heart failure (HF) death, hospitalization or an urgent visit for worsening HF.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Signs or symptoms of Heart Failure (HF) (NYHA FC I I and II I ) requiring treatment with at least one oral diuretic (any type)
  • Left ventricular ejection fraction (LVEF) ≥ 40% (by echocardiography at Screening)
  • Structural heart disease consistent with heart failure with preserved ejection fraction (HFpEF) established by echocardiography at Screening
  • Elevated NT-proBNP
  • Pulmonary vascular disease or right ventricular dysfunction

Exclusion Criteria:

  • Any prior valid measurement of LVEF < 40%. An echocardiogram is considered valid if its quality is sufficient to allow accurate assessment of LVEF and if it is reflective of the true status of the subject
  • Cardiovascular co-morbidities (e.g., significant unrepaired structural valvular heart disease; acute coronary syndrome, coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI) within 3 months of Screening; uncontrolled heart rate from atrial fibrillation or atrial flutter, history of serious life-threatening or hemodynamically significant arrhythmia; history of or anticipated heart transplant or ventricular assist device implantation, etc)
  • Systolic blood pressure (SBP) ≥ 180 mmHg, or diastolic blood pressure (DBP) ≥ 110 mmHg during Screening
  • Hemoglobin < 100g/L (< 10 g/dl) at Screening
  • Significant parenchymal lung disease (e.g., severe COPD, moderate or severe restrictive lung disease, diffuse interstitial fibrosis or alveolitis, pulmonary thromboembolism)
  • Severe renal dysfunction with an estimated Glomerular Filtration Rate (eGFR) < 30 mL/min per 1.73 m2
  • Severe hepatic impairment, e.g., Child Pugh Class C

Other protocol-defined inclusion/exclusion criteria may apply
