Clinical Trial Summary

A study to investigate the effect of single and repeated oral doses of ACT-539313 on what the body does to flurbiprofen, omeprazole, midazolam in healthy participants.

Description:

A screening evaluation will be performed within 3 to 28 days (or within 10 to 28 days for women of childbearing potential) before first study treatment administration. Prior to any screening assessment, participants must sign the informed consent form. Eligibility will be based on the results of the Screening and Day -1 assessments. The participants will be confined to the study site from the morning of Day -1 until the morning of Day 2, from the morning of Day 7 until the morning of Day 9 and from the morning of Day 14 until the morning of Day 16. Participants will return to the study site for the End of Study examination on Day 17.

Exclusion Criteria:

• History of major medical or surgical disorders which, in the opinion of the investigator, are likely to interfere with the absorption, distribution, metabolism, or excretion of the study treatment(s) (appendectomy and herniotomy allowed, cholecystectomy not allowed).
• Acute, ongoing, recurrent, or chronic systemic disease with the ability to interfere with the evaluation of the study results.
• Prior history of severe respiratory failure, acute respiratory depression, or sleep apnea.
• Prior history of peptic ulcer disease and/or gastrointestinal bleeding.
• Prior history of asthma, urticaria, or other allergic type reactions after taking acetylsalicylic acid or other NSAIDs.
• History of cardiovascular thrombotic events (including myocardial infarction and stroke) and coronary artery bypass graft surgery.
• Participation in a clinical study involving study treatment administered within 3 months (or 5 t 1/2 of the study treatment administered [whichever is longer]) prior to screening or in more than 4 clinical studies within 1 year prior to Screening.
• Previous treatment with any prescribed medications (including vaccines) or over-the-counter (OTC) medications (including herbal medicines such as St. John's Wort, homeopathic preparations, vitamins, and minerals; with the exception of ibuprofen [1200 mg/day] or paracetamol [up to 1500 mg/day] up until Day -1) within 3 weeks (or 5 t1/2 [whichever is longer]) prior to first study treatment administration.

Type	Measure	Description	Time frame	Safety issue
Other	Treatment-emergent adverse events	All adverse events will be collected, however, adverse events occurring during the in-between period (from end of period 1 up to first study treatment administration in period 2, are not considered as treatment-emergent adverse events.	From study treatment administration on Day 1 up to last assessment at End of Study (Day 17).
Other	Maximum plasma concentration (Cmax) of ACT-539313	In periods 2 (Day 8 and 9) and period 4 (Day 15, 16 and 17) the plasma pharmacokinetic parameters of ACT-539313 will be derived by non-compartmental analysis of the plasma concentration-time profiles. Cmax will be analyzed in periods 2 and 4 with the administration of probe substrate. In period 4 the Cmax will be determined after steady state ACT-539313 concentrations have been reached.	Pre-dose through to 24 hours post-dose.
Other	Time to reach Cmax (tmax) of ACT-539313	In periods 2 (Day 8 and 9) and period 4 (Day 15, 16 and 17) the plasma pharmacokinetic parameters of ACT-539313 will be derived by non-compartmental analysis of the plasma concentration-time profiles. tmax will be analyzed in periods 2 and 4 with the administration of probe substrate.
