Effect of Age-gender on the Pharmacokinetic and Pharmacodynamic Profiles of BIA 5 1058

Study Overview
=================
Brief Summary
-----------------
the purpose of this study is to determine the effect of age on the Pharmacokinetics (PK) profile of BIA 5-1058 at steady state after multiple oral doses

Detailed Description
-----------------
This was a single-centre, open-label, parallel group, non-randomised, two-part multiple dose 10-day study in healthy young and elderly male and female subjects. The study comprised a screening evaluation between 2 and 28 days before the first Investigational Medicinal Product (IMP) administration, a hospitalisation period of 15 days comprising a treatment period of 10 days, and a follow-up visit approximately 7 days after discharge. Part 1: Subjects received 1200 mg of BIA 5-1058 once a day (od), in fasting conditions, for 10 days Part 2 : Subjects received 400 mg of BIA 5-1058 od, in fasting conditions, for 10 days.

Young subjects only: Males and females aged between 18 and 40 years, inclusive. If female: No childbearing potential by reason of surgery or at least 1 year post-menopause (i.e., 12 months post last menstrual period), or menopause confirmed by follicle-stimulating hormone (FSH) testing; If of childbearing potential, using an effective non-hormonal method of contraception [intrauterine device or intrauterine system; condom or occlusive cap (diaphragm or cervical or vault caps) with spermicidal foam or gel or film or cream or suppository; true abstinence; or vasectomized male partner, provided that he is the sole partner of that subject] for all the duration of the study; If of childbearing potential, negative serum pregnancy test at screening and negative urine pregnancy test on admission to the study. Elderly subjects only: Males and females older than 65 years, inclusive. Exclusion Criteria: All subjects (young and elderly): Clinically relevant history or presence of respiratory, gastrointestinal, renal, hepatic, haematological, lymphatic, neurological, cardiovascular, psychiatric, musculoskeletal, genitourinary, immunological, dermatological, endocrine, connective tissue diseases or disorders; Clinically relevant surgical history; History of relevant atopy or drug hypersensitivity; History of alcoholism or drug abuse; Consumption of more than 14 units of alcohol a week [1 unit corresponds to 1 glass of 12° wine (10 cL), 1 glass of 45° pastis (2.5 cL), 1 glass of 40° whisky (2.5 cL), 1 glass of 12° champagne (10 cL), 1 glass of 18°aperitif drink (7 cL) or one 25-cL glass of 5°beer]; Significant infection or known inflammatory process at screening or admission to study; Acute gastrointestinal symptoms (e.g., nausea, vomiting, diarrhoea, heartburn) at the time of screening or admission to the study; Previous use of BIA 5-1058; Use of any investigational drug or participation in any clinical trial within 90 days prior to screening; Participation in more than 2 clinical trials within the 12 months prior to screening; Donation or reception of any blood or blood products within the 3 months prior to screening; Vegetarians, vegans or other medical dietary restrictions; Not able to communicate reliably with the Investigator; Unlikely to co-operate with the requirements of the study. If male: Not using an accepted effective method of contraception; Refusing to refrain from donating sperm throughout the study. Young subjects only: Use of medicines within 2 weeks of admission that could affect the safety or other study assessments, in the Investigator's opinion; If female of childbearing potential: Pregnant or breastfeeding; Not using an accepted effective contraceptive method or using oral contraceptives. Elderly subjects only: For elderly subjects, previously prescribed medications that interfered with absorption, distribution, metabolism, and excretion or safety/tolerability evaluation of BIA 5-1058 and adrenal or renal function were prohibited; however, previously prescribed medications that did not interfere with absorption, distribution, metabolism, and excretion or safety/tolerability evaluation of BIA 5-1058, adrenal or renal function and which could not interfere with the objectives of the study were allowed if the dose regimen had been stable for at least 4 weeks and was expected to remain stable throughout the study. Such concomitant medications were to be reviewed and mutually agreed upon by the Sponsor and the Investigator.
