Summary

This study's primary aim is to compare time to relapse and relapse rates in responders to acute escitalopram who are then randomized to placebo versus continuation treatment with escitalopram.

Detailed description

We propose to conduct the first pharmacotherapy relapse prevention study in body dysmorphic disorder (BDD). BDD, an often-delusional preoccupation with a nonexistent or slight defect in appearance, is a distressing, impairing, and common body image disorder. It is associated with high rates of functional impairment and markedly poor quality of life. It appears that serotonin reuptake inhibitors (SRIs) are often--and selectively--efficacious for BDD and that many BDD patients receive SRIs. It also appears that most patients discontinue an efficacious SRI at some point, as the alternative is life-long treatment. However, no relapse prevention studies have been done. Such a study is important from a clinical and public health perspective, because BDD appears to often be chronic and require long-term treatment. It is therefore critically important to investigate the risk of relapse with SRI discontinuation, and whether continuation SRI treatment decreases relapse risk. Subjects will be enrolled and first treated openly for 14 weeks with escitalopram; 58 escitalopram responders will then be randomized to double-blind continuation treatment with escitalopram or placebo for 6 additional months. Our primary aim is to compare time to relapse and relapse rates in responders to acute escitalopram who are then randomized to placebo versus continuation treatment with escitalopram. Secondary/exploratory aims will explore 1) Whether subjects who receive continuation escitalopram perform better on secondary outcome measures (e.g., quality of life) than those on placebo; 2) Change in symptoms with continuation of escitalopram during the continuation phase; and 3) Acute treatment response. In summary, this study will be the first relapse prevention study in BDD and the first study of continuation pharmacotherapy in BDD. It will provide critically important information on relapse with continuation versus discontinuation of an SRI, whether continuation treatment protects against relapse, and change in symptoms with continuation treatment. This study will yield unique and clinically important data, and will fill gaps in knowledge about this common, severe, and understudied illness.

Interventions

Type	Name	Description
DRUG	Escitalopram	At the end of the initial 14-week phase (open-label escitalopram), participants who responded to open-label escitalopram were randomly assigned to receive escitalopram (same dose as received in Phase I) for an additional 6 months.
DRUG	Placebo	At the end of the initial 14-week phase (open-label escitalopram), participants who responded to open-label escitalopram were randomly assigned to receive placebo for an additional 6 months.
