NCT ID: NCT02181231

Last Updated: 2019-06-04

Results Overview

Measure of depression severity, range of 0-60, with higher scores indicating more severe depression. We calculated the mean change in depression for both groups using baseline MADRS and week 8 MADRS scores.

PRIMARY outcome

Measure of depression severity, range of 0-60, with higher scores indicating more severe depression. We calculated the mean change in depression for both groups using baseline MADRS and week 8 MADRS scores.

PRIMARY outcome

Timeframe: Week 1 and week 8

Three item side effect scale used to assess frequency and intensity of side effects (range 0-6 for each item). We calculated the total score of all three items (range 0-18) with lower numbers indicating less frequency. We calculated the mean score at baseline and week 8 (final timepoint).

PRIMARY outcome

Timeframe: Baseline and 8 weeks

Measure of side effects, consisting of 21 items, ranging from 0-3 (0 indicates no side effect, 3 indicates severe side effect). We calculated the total final score for the 21 items (total range is 0-63). A higher total number represents a greater severity in reported side effects. We calculated the mean change in side effects for both groups using baseline and 8 week data.

SECONDARY outcome

Timeframe: Baseline and 8 weeks

A 19 item scale used to measure the presence or absence of suicidal ideations and the degree of severity of suicidal ideas. For this study, we computed the total score for all 19 items (total range 0-90). Higher scores represent a worse outcome. We also calculated the mean change in suicidal ideation for both groups using baseline and week 8 (final timepoint).

SECONDARY outcome

Timeframe: Baseline and 8 weeks

Measure of anxiety. Six anxiety symptoms are rated based on how distressed the subject is for each symptom. The range for each symptom is 0-4, with 4 representing extreme distress. We computed the mean of the final BSI score (range 0-24), with a lower number indicating a better outcome. We also calculated the mean change in anxiety for both groups using baseline and Phase 2 week 8 (final time point) data.
