Conditions
Brief summary
The purpose of this study is to assess the safety and tolerability of BIA 5-453 after single oral doses
Detailed description
Single centre, randomised, double-blind, placebo-controlled study of single ascending doses in 10 sequential groups of 8 healthy young male volunteers. Within each group (n=8), 6 volunteers were randomised to receive BIA 5-453 and the remaining 2 volunteers were randomised to receive placebo. A volunteer participated only in a single period.
Interventions
DRUGBIA 5-453
BIA 5-453 Gelatine capsule for oral administration (1, 10 or 20 mg). Single oral doses of BIA 4-543 2 mg, 10 mg, 20 mg, 50 mg, 100 mg, 200 mg, 400 mg, 600 mg, 900 mg and 1200 mg were administered to subjects in fasting conditions.
DRUGPlacebo
Placebo Gelatine capsule for oral administration. The composition of the placebo is qualitatively the same but without BIA 5-453 pharmaceutical active ingredient (API).

Inclusion criteria
1. A signed and dated informed consent form before any study-specific screening procedure was performed. 2. Aged between 18 and 45 years, inclusive. 3. Healthy as determined by the investigator on the basis of medical history, physical examination, clinical laboratory test results, vital signs and digital 12-lead electrocardiogram (ECG). 4. Nonsmoker or smoker of fewer than 10 cigarettes per day as determined by history. Must have been able to abstain from smoking during the inpatient stay. 5. Have a high probability for compliance with and completion of the study.
Exclusion criteria
Medical History 1. Any significant cardiovascular (e.g. hypertension), hepatic, renal, respiratory (e.g. childhood asthma), gastrointestinal, endocrine (e.g. diabetes, dyslipidemia), immunologic, dermatological, haematological, neurologic, or psychiatric disease. 2. Acute disease state (e.g., nausea, vomiting, fever, diarrhoea) within 7 days before study day 1. 3. History of drug abuse within 1 year before study day 1. 4. History of alcoholism within 1 year before day 1. Consumption of more than 50 g of ethanol per day (12.5 cL glass of 10° \[10%\] wine = 12 g; 4 cL of aperitif, 42° \[42%\] whiskey = 17 g; 25 cL glass of 3° \[3%\] beer = 7.5 g; 25 cL glass of 6° \[6%\] beer = 15 g 5. History of any clinically important drug allergy. Physical and Laboratory Findings 6. An automatic ECG QTc interval reading at screening or enrolment \>450 ms. 7. Positive serologic findings for human immunodeficiency virus (HIV) antibodies, hepatitis B surface antigen (HBsAg), and/or hepatitis C virus (HCV) antibodies. 8. Positive findings of urine drug screen (eg, amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine, methadone, opiates, MDMA \[3,4-methylenedioxy-methamphetamine; ecstasy\]). Prohibited treatments 9. Prohibited Treatments: use of any investigational drug within 90 days or prescription drug within 30 days before investigational medical product (IMP) administration. 10. Consumption of any caffeine-containing products (e.g., coffee, tea, chocolate, or soda) in excess of 6 cups per day (or equivalent), of grapefruit, grapefruit-containing products, or alcoholic beverages within 72 before study day -1. 11. Use of any over-the-counter drugs including herbal supplements (except for the occasional use of acetaminophen \[paracetamol\], aspirin and vitamins ≤100% recommended daily allowance) within 7 days before IMP administration. 12. Donation of blood (ie 450 ml) within 90 days before study day 1.
