Trial Outcomes & Findings for Switching to Duloxetine in Patients With Depression (NCT NCT00696774)

NCT ID: NCT00696774

Last Updated: 2010-09-08

Results Overview

BPI-SF interference score asks about the degree to which pain interferes with mood, walking and other physical activity, work, social activity, relations with others, and sleep. BPI-SF interference score ranges from 0 (no interference) to 10 (interferes completely). Response is defined as a \>=50% reduction in the Maier subscale score from baseline. The Maier subscale (Items 1,2,7,8,9,10) represents "core" symptoms of depression. Total subscale scores range from 0 (normal) to 24 (severe). Factors used for adjustment for least squares means are listed in 'Other relevant information' section.

PRIMARY outcome

Timeframe: Baseline, 4 weeks

Population: Efficacy Population: Participants who had at least one post-baseline observation were included in the efficacy analysis. The group "Unclassified" was excluded from statistical testing.

BPI-SF interference score asks about the degree to which pain interferes with mood, walking and other physical activity, work, social activity, relations with others, and sleep. BPI-SF interference score ranges from 0 (no interference) to 10 (interferes completely). Response is defined as a \>=50% reduction in the Maier subscale score from baseline. The Maier subscale (Items 1,2,7,8,9,10) represents "core" symptoms of depression. Total subscale scores range from 0 (normal) to 24 (severe). Factors used for adjustment for least squares means are listed in 'Other relevant information' section.

A 14-item patient-rated scale assesses medication-related changes in sexual activity/functioning. Items rated from 1 (never, low enjoyment/pleasure) to 5 (every day, great enjoyment/pleasure). CSFQ measures 5 dimensions of sexual behavior: pleasure; desire/frequency; desire/interest; arousal; orgasm. Lower total scores are associated with diminished sexual functioning. Total scores \<=47 (men) and \<=41 (women) indicate global sexual dysfunction, with all phases of sexual response cycle affected. Factors used for adjustment for least squares means are in 'Other relevant information' section.

The TSQM is a participant-reported measure that best describes how the study medication makes them feel since the last study visit, assessing perceived effectiveness, severity of side effects, and convenience. Convenience, Effectiveness, Side-Effects, and Global Satisfaction scale scores range from 0 (extremely dissatisfied) to 100 (extremely satisfied). Factors used for adjustment for least squares means are listed in 'Other relevant information' section.

The SDS is completed by the patient and is used to assess the effect of the patient's symptoms on their work/social/family life. Total scores range from 0 to 30 with higher values indicating greater disruption in the patient's work/social/family life. Factors used for adjustment for least squares means are listed in 'Other relevant information' section.
