Brief summary

This project will attempt to enhance and augment the antidepressant efficacy of a commonly used antidepressant in poorly responding bipolar depressed patients.

Detailed description

This is a placebo-controlled study of patients with bipolar I disorder (BPD) utilizing a well-known antidepressant, escitalopram (ESC), in combination with the anti-inflammatory agent, celecoxib (CBX). The investigators hypothesize that combination treatment will lead to a qualitatively and quantitatively augmented response and will result in greater numbers of remitters compared to ESC monotherapy.

Interventions

DRUGEscitalopram

Escitalopram is a Selective Serotonin Reuptake Inhibitor (SSRI)

DRUGCelecoxib

Celecoxib is a nonsteroidal anti-inflammatory drug

DRUGPlacebo

Placebo is a manufactured capsule with no active ingredient

MeasureTime frameDescription
Response to Treatment8 weeksParticipants complete the Hamilton Depression Rating Scale (HDRS-17). The HDRS-17 is a clinician-administered assessment scale measuring the melancholic and physical symptoms of depression. Possible scores range from 0 to 54 (i.e., where higher scores indicate worse depression). In this study, response to treatment is defined as a reduction in the HDRS-17 score of at least 50% after 8 weeks of treatment.
Disease Remission8 weeksParticipants complete the Hamilton Depression Rating Scale (HDRS-17). The HDRS-17 is a clinician-administered assessment scale measuring the melancholic and physical symptoms of depression. Possible scores range from 0 to 54 (i.e., where higher scores indicate worse depression). In this study, diisease remission is defined as an HDRS-17 score less than 8 points after 8 weeks of treatment.
