Phase 1
Completed
Conditions
Schizophrenia

Registration Number
NCT00527020
Lead Sponsor

Brief Summary

GSK1018921 is a new drug under development for the treatment of schizophrenia. GSK1018921 differs from other available drugs in its mode of action and it is assumed that it may have an effect in the treatment of so-called positive symptoms such as hallucinations and negative symptoms such as lack of drive. No clinical studies have been conducted with GSK1018921 in humans until now. This is the first study where this compound is administered to humans; the study has 2 parts: Part A is a dose escalation study, Part B is a pharmacodynamic portion in a separate group of healthy smoker volunteers.

Detailed Description

Single-Blind, Randomised, Placebo-Controlled First Time in Human Study to Evaluate Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Single Oral Escalating Doses of GSK1018921 in Healthy Volunteers and to assess the effect of a single dose of GSK1018921 on quantitative EEG and Mismatch Negativity in a separate cohort of healthy smoker volunteers
