Double-Blind Lamictal (Lamotrigine) in Neurotic Excoriation

This study has been completed.

Jon Grant, University of Chicago Identifier:
First received: August 7, 2007

Last verified: August 2013
The goal of the proposed study is to evaluate the comparative efficacy of Lamictal (lamotrigine) to placebo in neurotic excoriation. Thirty subjects with neurotic excoriation will receive 12 weeks of double-blind treatment with Lamictal (lamotrigine) or matching placebo. The hypothesis to be tested is that Lamictal (lamotrigine) will be more effective than placebo in patients with neurotic excoriation. The proposed study will provide needed data on the treatment of a disabling disorder that currently lacks a clearly effective treatment.

Primary Outcome Measures:
  • The Yale-Brown Obsessive Compulsive Scale Modified for Neurotic Excoriation (NE-YBOCS) Will be the Primary Outcome Measure [ Time Frame: beginning and at each visit until the end of their participation in the study (12-weeks); investigator rated. Note: Reported mean and standard deviation is the final reported data point. ]
    The Yale-Brown Obsessive Compulsive Scale Modified for Neurotic Excoriation (NE-YBOCS) was the primary outcome measure - severity of illness. The NE-YBOCS is a reliable and valid, 10-item, clinician-administered scale that rates buying symptoms within the last seven days, on a severity scale from 0 to 4 for each item (total scores range from 0 to 40 with higher scores reflecting greater illness severity).
