Trial overview

Official title: A study to Investigate Potential Interactions between GSK598809 and Ethanol in Healthy Subjects
Trial description: This study will investigate the possible effects of alcohol in combination with GSK598809 on the central nervous system in 20 healthy male and female volunteers, between 18 and 65 years of age.
During 4 separate study periods subjects will receive the following treatment combinations: Alcohol + GSK598809, alcohol + placebo drug, placebo infusion + GSK598809, and placebo infusion + placebo drug. A placebo is a pill or liquid infusion which contains no drug or alcohol; it is a dummy version. Therefore it is administered in the same way that either the study drug or ethanol is depending on which placebo it is. All study drugs are administered in a random order and both the doctor and the participant are not aware of the treatment combination. However treatment combinations will be available at the end of the study or in case of an emergency. GSK598809 is administered orally and alcohol is administered per infusion. The duration of the infusion is 5 hours, during which approximately 75 grams of alcohol is infused, which is comparable to less than one bottle of wine.
Primary purpose:
Treatment
Trial design:
Crossover Assignment
Masking:
Double (Participant, Investigator)
Allocation:
Randomized
Primary outcomes:

Safety and tolerability: Vital sign measurement, 12 lead ECG and telemetry, safety laboratory sampling including prolactin and lipid measurements, Barnes Akathesia Scale (BAS), Simpson-Angus Scale (SAS) and Abnormal Involuntary Movement Scale (AIMS).

Timeframe: Screening: BAS, SAS and AIMS (as training only), 12 lead ECG, vital signs and clinical labs. All will be measured throughout dosing day (Day 1), day 2, 3: vital signs, day 4: vital signs, clinical labs, follow up: clinical labs, vital signs, 12 lead ECG

Pharmacokinetics: breath ethanol concentrations, blood ethanol concentrations, main pharmacokinetic parameters of GSK598809 and its metabolite (GSK685249) AUC∞, Cmax, Tmax and t½.

Timeframe: All will be measured throughout day 1, PK blood sampling for GSK598809 and GSK685249 will also be collected on Day 2, 3 and 4.

Pharmacodynamic: saccadic eye movements, smooth pursuit eye movements, body sway, adaptive tracking, Visual Verbal Learning Test (VVLT).

Timeframe: Saccadic eye movement, smooth pursuit eye movements, body sway and adaptive tracking measured at set intervals between 1.5hrs pre dose to 7.5hrs post dose. VVLT administered between 0.5hrs post dose to 3.5hrs post dose.

Secondary outcomes:

Pharmacodynamic/biomarker endpoints: saccadic eye movements, visual analogue scales (VAS B&L) according to Bond & Lader, Visual Analogue Scales for 'alcohol effects' (VAS 'Alcohol Effects').

Timeframe: Saccadic eye movements at time points as given above. VAS B&L and VAS 'Alcohol Effects' at following time points: -1.5, 0.5, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 7.5 hrs post dose.
