Brief summary

The purpose of this study is to evaluate the efficacy of vortioxetine (5, 10, and 20 mg) versus placebo during the first 28 weeks of the 32-week double-blind treatment period in the prevention of relapse in participants with MDD who responded to acute treatment with vortioxetine 10 mg.

Detailed description

The drug being tested in this study is called vortioxetine. Vortioxetine is being tested for the prevention of relapse in adults with major depressive disorder (MDD) who respond to daily treatment with vortioxetine. This study will look at relapse rates of MDD in people who take vortioxetine. The study will enroll approximately 1100 participants. All participants will receive vortioxetine 10 mg open-label for the first 16 weeks of the study. Participants who meet the appropriate MDD response criteria from the Week 8 Visit through Week 16 Visit will be eligible for randomization into the double-blind treatment period. Participants will be randomly assigned (by chance, like flipping a coin) to one of the four treatment groups-which will remain undisclosed to the patient and study doctor during the study (unless there is an urgent medical need): * Vortioxetine 5 mg * Vortioxetine 10 mg * Vortioxetine 20 mg * Placebo (dummy inactive pill) - this is a capsule that looks like the study drug but has no active ingredient All participants will be asked to take one capsule at the same time each day throughout the study. This multi-center trial will be conducted in the United States. The overall time to participate in this study is up to 55 weeks. Participants will make 19 visits to the clinic, and will be contacted by telephone 4 weeks after last dose of study drug for a follow-up assessment.

Time to relapse was defined as date of relapse - date of randomization + 1 (where date of relapse is the date of last dose, or date of last contact if date of last dose is missing, for participant with a relapse). Participants without relapse were censored at date of withdrawal or date of Week 28 visit, whichever was earliest. MADRS is a 10-item clinician rated scale to measure overall severity of depressive symptoms (i.e., apparent sadness, reported sadness, inner tension, etc.) rated on a 7-point Likert scale from 0 (normal) to 6 (most abnormal) with a total score ranges from 0 to 60. Higher scores indicate greater severity of symptoms. The inter-quartile range (IQR) was 25th percentile to 75th percentile.

Time From Randomization to Relapse of Major Depressive Disorder During the First 28 Weeks of the 32-Week Double-Blind Treatment Period

Relapse was defined as either 1) MADRS Score ≥22, 2) lack of efficacy as determined by the investigator or 3) other unsatisfactory treatment response judged by the investigator. Time to relapse was defined as date of relapse - date of randomization + 1 (where date of relapse is the date of last dose, or date of last contact if date of last dose is missing, for participant with a relapse). Participants without relapse were censored at date of withdrawal or date of Week 28 visit, whichever was earliest. MADRS is a 10-item clinician rated scale to measure overall severity of depressive symptoms (i.e., apparent sadness, reported sadness, inner tension, etc.) rated on a 7-point Likert scale from 0 (normal) to 6 (most abnormal) with a total score ranges from 0 to 60. Higher scores indicate greater severity of symptoms. The inter-quartile range (IQR) was 25th percentile to 75th percentile.

Time frame: From date of double-blind randomization (Week 16) up to relapse or first 28 weeks of Double-blind Period which occurs first (Up to Week 44)

Population: Full Analysis Set (FAS) included all participants who were randomized in the double-blind period and received at least 1 dose of double-blind study drug.

Change From Baseline in Clinical Global Impression Scale-Severity (CGI-S) Score at Each Week Assessed

The CGI-S is a 7-point scale that requires the clinician to rate the severity of the participant's illness at the time of assessment, relative to the clinician's past experience with participant who have the same diagnosis. Considering total clinical experience, a participant was assessed on severity of mental illness on the following scale: 1=normal, not at all ill; 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=extremely ill. Baseline II is defined as the last non-missing observation prior to the first dose of double-blind study drug. MMRM was used for analyses.

Time frame: Double-blind Baseline (BL) II and Double-blind Period: Weeks 2, 4, 8, 12, 16, 20, 24, 28, and 32

Population: FAS included all participants who were randomized in the double-blind period and received at least 1 dose of double-blind study drug. Number analyzed is the number of participants with data available for analysis at the given time-point.

Change From Baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score

MADRS is a 10-item clinician rated scale to measure overall severity of depressive symptoms (i.e., apparent sadness, reported sadness, inner tension, etc.) rated on a 7-point Likert scale from 0 (normal) to 6 (most abnormal) with a total score range from 0 to 60. Higher score indicates greater severity of symptoms. Baseline II is defined as the last non-missing observation prior to the first dose of double-blind study drug. Mixed model for repeated measures (MMRM) was used for analyses.

Time frame: Double-blind Baseline (BL) II and Double-blind Period: Weeks 2, 4, 8, 12, 16, 20, 24, 28, and 32

Population: FAS included all participants who were randomized in the double-blind period and received at least 1 dose of double-blind study drug. Number analyzed is the number of participants with data available for analysis at the given time-point.

Clinical Global Impression Scale-Global Improvement Scale (CGI-I) Score

The CGI-I scale assesses the participant's improvement (or worsening) as assessed by the clinician relative to Baseline on a 7-point scale where 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse.

Time frame: Week 32

Population: FAS included all participants who were randomized in the double-blind period and received at least 1 dose of double-blind study drug. Overall number of participants analyzed is the number of participants with data available for analyses.

Time From Randomization to Relapse of Major Depressive Disorder During the Entire 32-Week Double-Blind Treatment Period

Relapse was defined as either 1) MADRS Score ≥22, 2) lack of efficacy as determined by the investigator or 3) other unsatisfactory treatment response judged by the investigator. Time to relapse was defined as date of relapse - date of randomization + 1 (where date of relapse is the date of last dose, or date of last contact if date of last dose is missing, for participant with a relapse). Participants without relapse were censored. MADRS is a 10-item clinician rated scale to measure overall severity of depressive symptoms (i.e., apparent sadness, reported sadness, inner tension, etc.) rated on a 7-point Likert scale from 0 (normal) to 6 (most abnormal) with a total score ranges from 0 to 60. Higher scores indicate greater severity of symptoms. The IQR was 25th percentile to 75th percentile.

Time frame: From date of double-blind randomization (Week 16) up to relapse or 32 weeks of Double-blind Period which occurs first (Up to Week 44)

Population: FAS included all participants who were randomized in the double-blind period and received at least 1 dose of double-blind study drug.
