• Negative screen for alcohol and drugs of abuse at the Screening Visit and on admission to each treatment period.
• Subject had to be willing and able to be confined to the clinical unit and had to adhere to the study and lifestyle restrictions.
• Male subjects had to use together with his female partner/spouse a highly effective contraception form of birth control in combination with a barrier method throughout the clinical study period. And agreed not to father a child or to donate sperm starting at the Screening Visit and throughout the clinical study.
• Female subjects had to either be of non childbearing potential or had to use highly effective methods of contraception from at least 3 months before the Screening Visit and throughout the clinical study in combination with a barrier method.

15. Electrocardiogram (mean of triplicate) with corrected QT interval using the Fridericia's formula (QTcF) > 450 ms at the Screening Visit or admission to the first treatment period.

16. Having an estimated glomerular filtration rate (eGFR) < 90 mL/min, based on creatinine clearance calculation by the Cockcroft Gault formula and normalized to an average surface area of 1.73m2.

17. Previous use of BIA 5 1058.

18. Use of any investigational drug or participation in any clinical study within 60 days or 5 half life times, whichever was longer, before first administration of IMP.

19. Having received IMP in more than 3 studies within 12 months before the Screening Visit.

20. Donated or received blood within 56 days before first administration of IMP.

21. Donated or received plasma within 30 days before first administration of IMP.

22. History of any significant bleeding within the last 56 days prior to first administration of IMP.

23. Vegetarians, vegans or other medical dietary restrictions.

24. Not able to communicate reliably with the Principal Investigator.

25. Unlikely to comply with the requirements of the study.

26. Use of over the counter (OTC) medications (including oral natural health products, vitamin and herbal supplements) within 7 days before the first IMP administration until the Follow up Visit. Use of prescription medications that could have affected the safety or other study assessments, in the Principal Investigator's opinion, within 14 days before the first IMP administration until the Follow-up Visit. By exception, acetaminophen/paracetamol 1000 mg/day was permitted. CYP2B6, CYP2C8, CYP2D6, CYP3A4 (BIA 5-1058 metabolism) and CYP2C9, CYP2C19, CYP3A4 (bosentan metabolism): Use of inhibitors taken within 7 days before the first IMP administration and inducers taken within 28 days before first IMP administration.

27. Any known allergy or contra-indication to any of the IMPs or their content.

28. The subject was an employee or the close relative of an employee of the Sponsor or the Contract Research Organization (CRO) involved in the clinical study.
