Inclusion Criteria
  • Signed informed consent in a language understandable to the participant prior to any study-mandated procedure.
  • Healthy male participant aged between 18 and 45 years (inclusive) at Screening.
  • Body mass index of 18.5 to 28.0 kg/m2 (inclusive) at Screening.
  • Systolic blood pressure 100-140 mmHg, diastolic blood pressure 50-90 mmHg, and pulse rate 45-90 beats per minute (inclusive), measured on either arm, after 5 min in the supine position at Screening and on Day -1.
Exclusion Criteria
  • Previous exposure to ACT-1014-6470.
  • Known hypersensitivity to ACT-1014-6470, omeprazole, substituted benzimidazoles, midazolam, or treatments of the same pharmacological classes, or any of their excipients.
  • History or clinical evidence of any disease and/or existence of any surgical or medical condition, which in the opinion of the investigator, are likely to interfere with the absorption, distribution, metabolism, or excretion of the study treatment (appendectomy and herniotomy allowed if performed more than 12 weeks prior to administration of [first] study treatment, cholecystectomy not allowed).
  • Previous treatment with any prescribed medications (including vaccines [Vaccination regimen against COVID-19 completed less than 2 weeks prior to first study treatment administration or any vaccination against COVID-19 planned before end-of-study]) or over-the-counter (OTC) medications (including herbal medicines such as St John's Wort, homeopathic preparations, vitamins, and minerals) within 3 weeks prior to first study treatment administration.
  • Legal incapacity or limited legal capacity at Screening.
  • Participant with rare inherited issues of fructose intolerance, glucose-galactose malabsorption, or sucrase-isomaltase insufficiency.
