A Study of Lumateperone Versus Placebo in Participants With Major Depressive Disorder (CANDLE)

27. august 2026 opdateret af: Intra-Cellular Therapies, Inc.

A Phase 3, Randomized, Double-Blind, Placebo-Controlled, Multi-Center Study to Assess the Efficacy and Safety of Fixed Doses of Lumateperone Administered as Monotherapy in Participants With Major Depressive Disorder and an Open-label Long-term Extension Treatment With Lumateperone

The purpose of the study is to assess how well each dose of lumateperone (Dose 1 and 2) works when given alone as compared to placebo in participants with major depressive disorder (MDD; a medical condition characterized by a persistent feeling of deep sadness, hopelessness, and a loss of interest in activities for a prolonged period of time and interfere with ability to function).

Foranstaltningsbeskrivelse
Tidsramme
Change from DB Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score to End of Week 6
Tidsramme: DB Baseline (Day 1) up to Week 6
The MADRS is a 10-item clinician-rated scale designed to measure the overall severity of depressive symptoms. The MADRS total score ranges from 0 to 60 where higher score indicates more severity in symptoms.
DB Baseline (Day 1) up to Week 6

Foranstaltningsbeskrivelse
Tidsramme
Change from DB Baseline in Clinical Global Impression-Severity (CGI-S) Score to Week 6
Tidsramme: DB Baseline (Day 1) up to Week 6
The CGI-S evaluates the severity of participant's depressive symptoms on a scale of 0 to 7. Considering total clinical experience, a participant is assessed on severity of mental illness at the time of rating according to: 0=not assessed; 1=normal (not at all ill); 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among the most extremely ill participants.
DB Baseline (Day 1) up to Week 6
Change from DB Baseline in MADRS Total Score to Week 2
Tidsramme: DB Baseline (Day 1) up to Week 2
The MADRS is a 10-item clinician-rated scale designed to measure the overall severity of depressive symptoms. The MADRS total score ranges from 0 to 60 where higher score indicates more severity in symptoms.
DB Baseline (Day 1) up to Week 2
Change from DB Baseline in MADRS Total Score to Week 1
Tidsramme: DB Baseline (Day 1) up to Week 1
The MADRS is a 10-item clinician-rated scale designed to measure the overall severity of depressive symptoms. The MADRS total score ranges from 0 to 60 where higher score indicates more severity in symptoms.
