A Study to Evaluate the Efficacy, Safety, and Tolerability of Flexible Doses of Intranasal Esketamine Plus an Oral Antidepressant in Adult Participants With Treatment-resistant Depression (TRANSFORM-2)

A Randomized, Double-blind, Multicenter, Active-controlled Study to Evaluate the Efficacy, Safety, and Tolerability of Flexible Doses of Intranasal Esketamine Plus an Oral Antidepressant in Adult Subjects With Treatment-resistant Depression

The purpose of this study is to compare the efficacy and safety of switching treatment-resistant depression (TRD) subjects from a prior antidepressant treatment (to which they have not responded) to either intranasal esketamine plus a new oral antidepressant or switching to a new oral antidepressant plus intranasal placebo.

Study Overview

• Status: Completed
• Conditions: Treatment-resistant Depression
• Intervention / Treatment: Drug: Esketamine; Drug: Duloxetine (Oral Antidepressant); Drug: Escitalopram (Oral antidepressant); Drug: Sertraline (Oral Antidepressant); Drug: Venlafaxine Extended Release (XR) (Oral Antidepressant); Drug: Placebo

Detailed Description

This is a randomized, double-blind (neither the researchers nor the subjects know what treatment the subject is receiving), active-controlled, multicenter study (more than 1 study site) in subjects with TRD to assess the efficacy, safety, and tolerability of flexible doses of intranasal esketamine plus a newly initiated oral antidepressant compared with a newly initiated oral antidepressant (active comparator) plus intranasal placebo. The study will consist of 3 phases: Screening/Prospective Observational Phase (4-7 weeks), Double-blind Induction Phase (4-weeks), Follow-up Phase (24-weeks). Subjects who rollover into a long-term maintenance study will not participate in the Follow-up Phase. The antidepressant treatment, as well as any other ongoing medications being taken for depression at screening (including adjunctive/ augmentation therapies), will continue unchanged, at the same dosage, from the start of Week 1 through the end of Week 4 of the screening/prospective observational phase. Subjects' safety will be monitored throughout the study.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score up to Day 28 in the Double-blind Induction Phase- Mixed-Effects Model Using Repeated Measures (MMRM) Analysis	MADRS is clinician-rated scale designed to measure depression severity, and to detect changes due to antidepressant treatment. Scale consists of 10 items (apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts), each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of symptoms), summed for a total possible score of 0 to 60. Higher scores represent more severe condition.	Baseline up to Day 28 of Double-blind Induction Phase
Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score up to Endpoint (Double-blind Induction Phase [Day 28])- Analysis of Covariance (ANCOVA) Analysis	MADRS is clinician-rated scale designed to measure depression severity, and to detect changes due to antidepressant treatment. Scale consists of 10 items (apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts), each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of symptoms), summed for a total possible score of 0 to 60. Higher scores represent more severe condition. The last post baseline observation during the phase was carried forward as "End Point" for that phase.

Score for first 3 items are summed to create total score of 0-30 where higher score indicates greater impairment and a negative change in score indicates improvement. It also has one item on days lost from school or work and one item on days when under productive.	Baseline up to Day 28 of Double-blind Induction phase

Each item is rated on 4-point scale (0=Not at all, 1=Several Days, 2=More than half days, 3=Nearly every day. Scale scores each of 9 symptom domains of Diagnostic and Statistical Manual of Mental Disorders, Major Depressive Disorder criteria and it has been used both as screening tool and measure of response to treatment for depression. The participant's item responses are summed to provide a total score (range of 0 to 27) with higher scores indicating greater severity of depressive symptoms. Severity of PHQ-9 categorized as follows: None-minimal (0-4), Mild (5-9), Moderate (10-14), Moderately Severe (15-19), Severe (20-27).	Baseline up to Day 28 of Double-blind Induction phase

Scale consists of 10 items (apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts), each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of symptoms), summed for a total possible score of 0 to 60. Higher scores represent more severe condition. The percentage of participants with greater than or equal to (>=) 50 % reduction from baseline in MADRS total score was reported.

Change From Baseline in Generalized Anxiety Disorder (GAD-7) Total Score up to Endpoint (Double-blind Induction Phase [Day 28])	GAD-7 is a brief and validated 7-item self-report assessment of overall anxiety. Participants respond to each item using a 4-point scale with response categories of 0=not at all, 1=several days, 2=more than half the days, and 3=nearly every day. Item responses are summed to yield a total score with a range of 0 to 21, where higher scores indicate more anxiety. The recall period is 2 weeks. The severity of the GAD-7 is categorized as follows: None (0-4), Mild (5-9), Moderate (10-14) and Severe (15 -21). The last post baseline observation during the phase was carried forward as "End Point" for that phase.	Baseline up to Endpoint (Double-blind Induction Phase [Day 28])
Change From Baseline in EQ 5D-5L-Health Status Index to End of Double-blind Induction Phase (Day 28)	European Quality of Life Group-5 Dimension-5-Level (EQ-5D-5L) is a 2-part instrument for use as a measure of health outcome, designed for self-completion by respondents. It consists of EQ-5D-5L descriptive system and EQ VAS. EQ-5D-5L descriptive system comprises of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each has 5 levels of perceived problems (1-no problem, 2-slight problems, 3-moderate problems, 4-severe problems, 5-extreme problems). Participant selects answer for each of 5 dimensions considering response that best matches his/her health "today". Responses were used to generate a Health Status Index (HSI). Health Status Index range is -0.148 - 0.949, is anchored at 0 (dead) and 1 (full health).	Baseline up to End of Double-blind Induction Phase (Day 28)
Change From Baseline in EQ 5D-5L- European Quality of Life - Visual Analogue Scale (EQ-VAS) to End of Double-blind Induction Phase (Day 28)	EQ-5D-5L is a 2-part instrument for use as a measure of health outcome, designed for self-completion by respondents. It consists of EQ-5D-5L descriptive system and EQ VAS. The EQ VAS self-rating records the respondent's own assessment of his or her overall health status at the time of completion, on a scale of 0 (the worst health you can imagine) to 100 (the best health you can imagine).	Baseline up to End of Double-blind Induction Phase (Day 28)
Change From Baseline in EQ 5D-5L- Sum Score to End of Double-blind Induction Phase (Day 28)	EQ-5D-5L consists of EQ-5D-5L descriptive system and EQ visual analogue scale (EQ VAS). EQ-5D-5L descriptive system comprises of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each has 5 levels of perceived problems (1-no problem, 2-slight problems, 3-moderate problems, 4-severe problems, 5-extreme problems). Participant selects answer for each of 5 dimensions considering response that best matches his/her health "today". Responses were used to generate a Health Status Index (HSI). Health Status Index range is -0.148 - 0.949, is anchored at 0 (dead) and 1 (full health). EQ VAS self-rating records the respondent's own assessment of his/her overall health status at time of completion, on a scale of 0 (worst health you can imagine) to 100 (best health you can imagine). Sum score ranges from 0 to 100 where, sum score = (sum of the scores from the 5 dimensions minus 5) *5. Higher score indicates worst health state.
