Condition(s) targeted: Mental Disorders

Intervention: Cherry lamotrigine ODT (Drug); Cherry Placebo (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: GlaxoSmithKline

Official(s) and/or principal investigator(s):

The objective of this sensory analysis study is to determine whether volunteers observe a significant difference in organoleptic properties between lamotrigine (430C78) cherry flavoured orally disintegrating tablets (ODT) and a placebo cherry flavoured orally disintegrating tablet. The aim is to assess the value of the placebo as a marketing aid, whereby physicians and patients may assess the personal acceptability of the organoleptic properties and potential convenience prior to prescription of the ODT formulation.

- Currently or recently prescribed any medication which may be affected by lamotrigine

including antiepileptics.

- Participation in another sensory analysis study within 30 days preceding the test


- Treatment with an investigational drug within 30 days preceding the test day.

- Females with a positive hCG pregnancy test on the test day.

- Abuse of alcohol defined as an average weekly intake of greater than 21 units or an

average daily intake of greater than 3 units for men and a weekly intake of greater than14 units or an average daily intake of greater than 2 units for women. [NOTE: 1 unit is equivalent to a half-pint (220mL) of beer or 1 (25mL) measure of spirits or 1 glass (125mL) of wine]. Subjects must be willing to abstain from alcohol for 24 hours before each visit to the unit for the duration of the study.

- Where participation in the study would result in donation of blood or blood products

in excess of 500 mL within a 56 day period.
