Percent Change From Baseline in Body Weight at Week 28: Part A
Zeitfenster: Baseline (last non-missing measurement prior to the first dose), Week 28
|
Analysis was performed using mixed model for repeated measures (MMRM) with treatment group, visit, and treatment by visit interaction, sex, and baseline body weight as fixed effects using unstructured covariance.
The analysis excluded weight measurements after protocol specified intercurrent events (ICEs) including permanent treatment discontinuation, non-compliance to treatment and lifestyle change.

Each item was scored on scale of "0=not at all", "several days", "more than half the days" to "nearly every day".
The total score ranges from 0 to 27 by adding score for each question (total points) where: Score 1-4: minimal depression; Score 5-9: Mild depression; Score 10-14: moderate depression; Score 15-19 moderately severe depression; Score 20-27: Severe depression.
Higher score indicates greater severity of depression.
