Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Healthy on the basis of physical examination and medical and surgical history, performed at screening. If there are abnormalities, the participant may be included only if the investigator judges the abnormalities to be not clinically significant. This determination must be recorded in the participant's source documents and initialed by the investigator
  • Systolic blood pressure (SBP) between 100 and 145 millimeters of mercury (mmHg) (inclusive), diastolic blood pressure (DBP) between 50 and 90 mmHg (inclusive), and pulse rate between 45 and 90 beats per minute (inclusive), within 3 minutes after standing up and after the participant is supine for at least 5 minutes, at screening
  • Twelve-lead electrocardiogram (ECG) without clinically relevant abnormalities, at the discretion of the investigator, measured after the participant is supine for at least 5 minutes, at screening
  • Body weight not less than 50 kilograms (Kg) and body mass index (BMI; weight/height^2) within the range 18.5 -30 kg per meter square (kg/m^2) (inclusive)at screening
  • All women must have a negative highly sensitive serum (beta-human chorionic gonadotropin [beta-hCG]) pregnancy test at screening and a negative urine pregnancy test on Day -1 of the first treatment period

Exclusion criteria

  • Known allergies, hypersensitivity, or intolerance to any active substance or drugs of the same class, or any excipient of the drug formulation(s)
  • History or clinical evidence of any disease and/or existence of any surgical or medical condition which might interfere with the absorption, distribution, metabolism, or excretion of the study intervention(s) (appendectomy and herniotomy allowed, cholecystectomy not allowed)
  • A history of repeated fainting due to cardiac cause, collapse, syncope, orthostatic hypotension, or vasovagal reactions
  • Female participant who is breastfeeding at screening and plans to breastfeed throughout the study
  • Any condition for which, in the opinion of the investigator, participation would not be in the best interest of the participant (example, compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments

    Time frame: Predose, up to 336 hours post dose (up to Day 15)

    AUC(0-last) is defined as area under the plasma analyte concentration-time curve of macitentan from time zero to time of the last quantifiable (non-below quantification limit [BQL]) concentration.

  3. Area Under the Plasma Analyte Concentration-time Curve from Time Zero to Infinite Time (AUC[0-infinity]) of Macitentan

    AUC(0-infinity) is defined as area under the plasma analyte concentration-time curve of macitentan from time zero to infinite time.

Secondary outcomes

  1. Actual Sampling Time to Reach the Maximum Observed Plasma Analyte Concentration (Tmax) of Macitentan and its Metabolite Aprocitentan

    Time frame: Predose, up to 336 hours post dose (up to Day 15)

    Tmax is defined as actual sampling time to reach the maximum observed plasma analyte concentration of macitentan and its metabolite aprocitentan.

  2. Last Observed Measurable Plasma Analyte Concentration (Clast) of Macitentan and its Metabolite Aprocitentan

    Time frame: Predose, up to 336 hours post dose (up to Day 15)
