Brief summary: This is a single centre, double-blind, randomised, placebo-controlled, parallel staggered group study of BIA 5-1058 in 11 different cohorts of 15 healthy subjects. Subjects will be randomly assigned to receive once-daily oral doses of BIA 5-1058 or matching placebo for 10 days.

The primary objectives of the study are to assess the safety and tolerability of BIA 5-1058 after repeated ascending doses under fed and fasted conditions and to assess the pharmacokinetics (PK) of BIA 5-1058 after repeated ascending doses under fed conditions having matching fasting cohorts for comparison of bioavailability.

It is planned that comparison cohorts will be dosed in parallel, i.e. Cohorts 1 and 2, 3 and 4, 5 and 6, 7 and 8 and 9 and 10. Cohorts may be split or dosed sequentially for logistical purposes; however, data from both comparison cohorts (e.g. Cohorts 1 and 2) must be available before dose escalation to the next dose levels.

Detailed description: Each cohort will follow the same study design. Subjects will be screened for inclusion in the study between 28 and 3 days before the first dose. Eligible subjects will be admitted 2 days before dosing (Day -2) for all regimens, and will remain resident in the clinic until 72 h after the last dose (Day 13). On Day -1, blood samples will be taken in all cohorts for PD assessments at pre-defined time points. These time points will be time matched to Day 1 PK and PD time points. Subjects in Cohorts 2, 4, 6, 8, 10 and 11 (fed cohorts) will also undergo continuous cardiac monitoring via 24 h Holter recordings on Day -1.

Subjects in Cohorts 1, 3, 5, 7 and 9 will receive oral doses of BIA 5-1058 or matching placebo once daily from Day 1 to Day 10, administered in the morning of each day after a minimum of 8 h fast and will remain fasted until 4 h post-dose. Subjects in Cohorts 2, 4, 6, 8, 10 and 11 will receive oral doses of BIA 5-1058 or matching placebo once daily from Day 1 to Day 10, administered in the morning of each day, 30 minutes after the start of a moderate breakfast containing approximately 550 kcal with fat contributing approximately 150 kcal.

Eligibility criteria: Inclusion Criteria:

Able and willing to comply with the study restrictions and to give written informed consent before any study procedure; Male or non-pregnant, non-lactating female subjects aged 18 to 55 years, inclusive; Body mass index (BMI) between 18.0 and 32.0 kg/m2 or, if outside the range, considered not clinically significant by the investigator; Healthy as determined by the investigator based on medical history, physical examination, clinical laboratory test results, vital signs (systolic blood pressure ≥ 90 mmHg and ≤ 150 mmHg, diastolic blood pressure ≥ 50 mmHg and ≤ 90 mmHg) and digital 12-lead ECG); Negative tests for hepatitis B surface antigen (HBsAg), anti-hepatitis C virus antibodies (HCV Ab) and anti-human immunodeficiency virus antibodies (HIV-1 and HIV-2 Ab) at screening; Clinical laboratory test results clinically acceptable at screening and admission Negative screen for alcohol and drugs of abuse at screening and admission Non-smokers or ex-smokers for at least 3 months;

Must adhere to the contraception requirements:

Male subjects and female partner willing to a condom plus an approved method of effective contraception, if applicable (unless anatomically sterile or where abstaining from sexual intercourse is in line with the preferred and usual lifestyle of the subject) from the time of informed consent until 90 days after last dose of IMP. Male subjects must refrain from donating sperm throughout the study and for 90 days after the last dose of IMP; Female subjects of childbearing potential willing to use, with their partner, a condom and an approved method of highly effective contraception from the time of informed consent until 30 days after the last follow-up visit. Hormonal contraceptives are not permitted for female subjects. Female subjects must not donate ova from the time of the first dose until 90 days after the last dose of study drug; If female, nonchildbearing 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 Negative serum pregnancy test at screening and negative urine pregnancy test on admission (all female subjects).
