A Double-blind, Randomised, Placebo-controlled, Rising Multiple-dose Study to Investigate the Tolerability and Steady-state Pharmacokinetics of BIA 6-512 (Trans-resveratrol) in Healthy Volunteers

To investigate the tolerability and safety of four multiple-dose regimens of BIA 6-512 (25 mg, 50 mg, 100 mg, and 150 mg 6 times daily) in healthy volunteers and to characterise the steady-state pharmacokinetic profiles of BIA 6-512 (25 mg, 50 mg, 100 mg, and 150 mg 6 times daily) in healthy volunteers.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Single-centre, double-blind, randomised, placebo-controlled study of four multiple-rising doses in four sequential groups of 10 healthy volunteers each. Eligible subjects were admitted to the UFH on the day (Day 0) prior to receiving the first dose of study medication. On the morning of the next day (Day 1), subjects started receiving BIA 6-512/Placebo at 4 h intervals (6 times/day) for 48 h (13 investigational product administrations, in total). Subjects remained confined in the UFH from admission (Day 0) until at least 24 h post last dose (Day 4); then, they were discharged and were requested to return for the follow-up visit. At given time-points, subjects were submitted to vital signs recording, brief neurological examination, and 12-lead ECG. Blood samples for plasma drug assays were taken at the following times: Dose 1: pre-dose and ¼, ½, ¾, 1, 1½, 2, and 3 hours post-dose; Doses 2, 3, 4, 5, 7, 8, 9, 10, 11: pre-dose; Dose 13: pre-dose and ¼, ½, ¾, 1, 1½, 2, 3, 4, 6, 8, 12, 16 and 24 hours post-dose.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
