Eligibility
Primary outcome measure(s)
- To assess efficacy of ALTO-100 versus placebo on depression symptoms in bipolar disorder in a pre-defined subgroup of participants as measured by the mean change from Day 1 to Week 6 on the Montgomery-Åsberg Depression Rating Scale (MADRS) total score — Change assessed from Day 1 to Week 6
MADRS is a clinician-administered scale designed to measure depression severity and detects changes due to antidepressant treatment. The MADRS evaluates the following 10 items: apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts. Each item is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total possible score of 60. Higher scores represent a more severe condition.
