A Study to Evaluate Efficacy and Safety of Macitentan 75 mg in Inoperable or Persistent/Recurrent Chronic Thromboembolic Pulmonary Hypertension


Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Chronic Thromboembolic Pulmonary Hypertension
  • Age: Between 18 - 80 Years
  • Gender: Male or Female

Inclusion Criteria:

  • Chronic thromboembolic pulmonary hypertension (CTEPH) (World Health Organization [WHO] Group 4) fulfilling one of the following criteria: a) inoperable due to the localization of the obstruction being surgically inaccessible (that is, distal disease), b) persistent/recurrent CTEPH after balloon pulmonary angioplasty (BPA), and deemed inoperable due to the localization of the obstruction being surgically inaccessible (that is, distal disease), c) persistent/recurrent CTEPH after rescue pulmonary endarterectomy (PEA)
  • 6-minute walk distance (6MWD) greater than or equal to (>=) 100 meter (m) and less than or equal to (<=) 450 meters (m), documented by an eligibility and a baseline 6-minute walk test (6MWT). The baseline 6MWD must not differ by more than 15 percent (%) from the eligibility test
  • World Health Organization functional class (WHO FC) >= II
  • Participants are to receive riociguat as per local standard of care, unless it is contraindicated or unavailable

Exclusion Criteria:

  • Acute pulmonary embolism within 6 months prior to or during Screening
  • Planned (during the double-blind period of the study) balloon pulmonary angioplasty (BPA)
  • Significant obstructive and restrictive lung disease
  • Acute or chronic conditions (other than dyspnea) that limit the ability to comply with study requirements, in particular with 6MWT (for example, intermittent claudication).
  • Symptomatic coronary artery disease requiring an intervention within 3 months prior to or during Screening or anticipated during the DB period of the study
  • Decompensated cardiac failure if not under close supervision
  • Known and documented life-threatening cardiac arrhythmias
  • Acute myocardial infarction within 6 months prior to, or during Screening
  • Cerebrovascular events (including transient ischemic attack) within 3 months prior to, or during Screening
  • Known or suspicion of pulmonary veno-occlusive disease (PVOD)
  • Administration of ERAs, intravenous, or inhaled prostacyclins / prostacyclin analogs, or investigational treatment within 90 days prior to Randomization
  • Administration of riociguat within 90 days prior to Randomization (if its use as background medication becomes permissible based on pharmacokinetic Drug-drug interaction [DDI] data during the conduct of the study, this exclusion criterion will no longer apply)
  • Change in dose or initiation of Phosphodiesterase type-5 (PDE-5) inhibitors, oral prostacyclins / prostacyclin analogues, prostacyclin receptor agonists (or riociguat, if its use becomes permissible during the study) within 90 days prior to Randomization or anticipated during the 52-week double-blind [DB] period
  • Hypotension, that is, systolic blood pressure (SBP) less than (<) 90 millimeters of mercury (mmHg) or diastolic blood pressure (DBP) <50 mmHg at Screening.
  • Severe renal dysfunction with an estimated Glomerular Filtration Rate <30 milliliters per minute per 1.73 meter square (mL/min/1.73 m^2) using the Chronic Kidney Disease Epidemiology Collaboration formula at Screening
  • Known moderate to severe hepatic impairment, defined as Child-Pugh Class B or C, based on records that confirm documented medical history
  • Serum aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) greater than or equal to (>=) 1.5*upper limit of normal (ULN) at Screening
  • Hemoglobin <100 g/L (<10 gram per deciliter [g/dL]) at Screening
