A Study to Examine the Pharmacodynamic Effects of GSK1034702 on Neurophysiological Biomarkers of Cognition in Nicotine Abstained Otherwise Healthy Smokers

• Status: Completed
• Trial end date: 2010-06-18

Summary

This will be a double blind, randomised, placebo controlled, cross over study in which up to 20 otherwise healthy male nicotine abstinent smokers will be tested following 3 acute treatment conditions (placebo, 4 and 8mg of GSK1034702). Each subject will undergo screening assessments within 30 days prior to administration of the first dose of study medication. There will be 3 treatment sessions and dosing will be separated by a minimum 1 week washout period. There will be two testing days (day 1 and day 2) per treatment session. On each treatment session subjects will be admitted on day 1. On day 1, subjects will be administered placebo and approximately 3 hours later, there will be a Baseline EEG/ERP recording, neuropsychological (Cogstate battery) testing and mood/craving/dependence questionnaire assessments . Subjects will be allowed to smoke until approximately midnight on day 1. On day 2, subjects will undergo a pre-drug neuropsychological (Cogstate battery) testing and questionnaire assessments of mood/craving. This will be conducted approximately 1 hour prior to dosing. Subjects will be randomized to one of six treatment sequences. Post dose EEG/ERP recording, neuropsychological (Cogstate battery) testing and mood/craving measurements will be conducted between 3 and 6 hours post treatment to coincide with peak pharmacokinetic effects. This testing will be performed approximately at 12pm following at least 12hrs of nicotine abstinence. Blood samples will be collected at baseline (pre-drug) and following drug administration to quantify exposure levels.
