A Study to Evaluate the Effect of Single Doses of Drug A (Lamotrigine) and Drug B (Vofopitant) Alone and in Combination on Resting Motor Threshold in Healthy Subjects

Phase 1

Terminated

• Conditions: Bipolar Disorder
• Interventions: Drug: Placebo; Drug: Vofopitant; Drug: Lamotrigine

• Registration Number: NCT00907985
• Lead Sponsor: GlaxoSmithKline

Brief Summary

The purpose of this study is to investigate the effect of drug A on its own and when it is given in combination with drug B on markers of brain activity. The study will

1. Assess the effects of drug A and drug B on muscle movement after brain stimulation;

2. Examine how the body handles (absorbs, distributes, breaks down and gets rid of) drug A and drug B when given in combination;

3. Examine the safety of drug A and drug B when given together.
