• Healthy male or female subjects aged between 18 and 45 years (inclusive) at Screening.

• Body Mass Index of 18.5 to 28.0 kg/m2 (inclusive) at Screening.

• Women of childbearing potential must have a negative serum pregnancy test at Screening and a negative urine pregnancy test on Day -1. They must consistently and correctly use (from Screening, during the entire study, and for at least 30 days after study treatment intake) a highly effective method of contraception with a failure rate of < 1% per year, be sexually inactive, or have a vasectomized partner. If a hormonal contraceptive is used, it must have been initiated at least 1 month before treatment administration.

• Women of non-childbearing potential, i.e., postmenopausal (defined as 12 consecutive months with no menses without an alternative medical cause, confirmed by a FSH test), with previous bilateral salpingectomy, bilateral salpingo-oophorectomy or hysterectomy, or with premature ovarian failure (confirmed by a specialist), XY genotype, Turner syndrome, uterine agenesis.

• 12-lead ECG (including QT: < 450 milliseconds [for males] and < 470 milliseconds [for females] without clinically relevant abnormalities, measured after 5 min in the supine position at Screening and on Day -1.

Exclusion Criteria:

• Pregnant or lactating women.

• Any circumstances or conditions, which, in the opinion of the investigator, may affect full participation in the study or compliance with the protocol.

• Clinically relevant findings in clinical laboratory tests (hematology, clinical chemistry, and urinalysis, i.e. outside the reference ranges (< 0.9 lower limit of normal and > 1.1 upper limit of normal; except for relevant hepatic parameters [Alanine Aminotransferase (ALT), Aspartate Aminotransferase Test (AST), bilirubin] which must not exceed the upper limit of normal), at Screening and on Day -1.

• 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.
