Conditions
Brief summary
The purpose of this study is to assess the tolerability of BIA 5-453 after six multiple rising dose regimens of BIA 5-453.
Detailed description
Two centres, double-blind, randomised, placebo-controlled study of six dosage regimens of BIA 5-453 in six groups of healthy male subjects. In each group, the study consisted of a 10-day multiple-dose period. Progression to the next dose level only occurred if the previous dose level was considered to be safe and well tolerated. An appropriate interval separated the investigation of doses to permit a timely review and evaluation of safety data (including plasma exploratory pharmacokinetics) prior to proceeding to a higher dose level.
Interventions

Presented as blue hard gelatine capsules (size 2) of 1 mg, 10 mg and 50 mg for oral administration
DRUGPlacebo
The composition of the placebo is qualitatively the same but without BIA 5-453 pharmaceutical active ingredient.

| Measure | Time frame | Description |
|---|---|---|
| Percent of subjects with at least one adverse event | through study completion, an average of 10 days | — |
| Percent of subjects by dose group with at least one treatment-emergent adverse event (TEAEs) | through study completion, an average of 10 days | Treatment-emergent adverse events are adverse events that occurred either in the 72 hours after dosing or that was present prior to dosing but exacerbated within 72 hours after dosing. |
