---|---|
EXPERIMENTAL: Nuedexta (dextromethorphan/quinidine)
45/10 mg every 12 hours x 8 weeks
|
up to 45/10 mg every 12 hours in patients with TRD with a short 7 day tapering period in which subjects are tapered off 45/10 mg dose from twice a day to once daily for an additional 7 days at post 8-week treatment period to minimize the potential for discontinuation effects

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Montgomery-Asberg Depression Rating Scale
Time Frame: At baseline and visit 6 (week 10)
|
The Montgomery-Asberg Depression Rating Scale is a 10-item instrument used for the evaluation of depressive symptoms in adults and for the assessment of any changes to those symptoms.
Each of the 10 items is s scored 0 (normal) to 6 (severe depression) with overall score ranges from 0 (normal) to 60 (severe depression).
Primary outcome is change in MADRS at Visit 6 (Week 10).
Higher values represent a worse outcome.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Quality of Life Enjoyment and Satisfaction Questionnaire Short Form
Time Frame: At baseline and Visit 6 (week 10)
|
The Quality of Life Enjoyment and Satisfaction Questionnaire Short Form is a reliable and valid self-report measure designed to obtain sensitive measures of the degree of enjoyment and satisfaction experienced by individuals.
The raw total score ranges from 14 to 70.
Higher scores reflect better oucomes.
|
At baseline and Visit 6 (week 10)
|
Range of Impaired Functioning Tool
Time Frame: At baseline and Visit 6 (week 10)
|
The Range of Impaired Functioning Tool a brief scale for assessing functional impairment related to medical or psychiatric illness and has been demonstrated to possess good psychometric properties. The LIFE-RIFT has a total score and individual domain scores for the following areas of functioning: household duties, work, recreation, relationships with family, relationships with friends, schoolwork, and global life satisfaction (the satisfaction item is patient rated). Higher scores indicate poorer functioning; scores ≥2 reflect impaired functioning in that domain. Results are reported for the total sum with full range from 3 (no impairment) to 60 (severe impairment), which is based on all individual domain scores. |
At baseline and Visit 6 (week 10)
|
Sheehan Disability Scale
Time Frame: At baseline and Visit 6 (week 10)
|
The Sheehan Disability Scale (SDS) is a self-rated scale which assesses illness-related disability in three areas of functioning: work, social and family.
The SDS assess disability or functional impairment across three domains: work/school, social life/leisure activities and family life/home responsibilities.
Each domain is scored from 0 (not at all) to 10 (very severely).
The three domains can be summarized to evaluate global functional impairment by adding the scores of each of the three domains, resulting in global SDS score ranges from 0 (unimpaired) to 30 (highly impaired).
|
At baseline and Visit 6 (week 10)
|
Patient Rated Inventory of Side Effects (PRISE)
Time Frame: up to 12 weeks
|
Frequency of observed adverse events over the study treatment period as captured by the PRISE.
The Patient Rated Inventory of Side Effects (PRISE) assesses the presence of treatment side effects in nine organ/function systems (gastrointestinal, nervous system, heart, eyes/ears, skin, genital/urinary, sleep, sexual functioning, and other).
|
up to 12 weeks
|
Columbia-Suicide Severity Rating Scale (C-SSRS)
Time Frame: up to 12 weeks
|
The Columbia-Suicide Severity Rating Scale (C-SSRS) is a comprehensive, semi-structured interview measure that uniquely measures the full spectrum of suicidality including passive and active suicidal ideation, suicidal intent as well as suicidal behaviors.
Full range from 0 (low intensity suicidal ideation to 9 (high intensity suicidal ideation).
|
up to 12 weeks
|
Quick Inventory of Depressive Symptomatology, Self Report (QIDS-SR)
Time Frame: up to 12 weeks
|
The Quick Inventory of Depressive Symptomatology, Self Report (QIDS-SR) is a 16-item self rated instrument designed to assess the severity of depressive symptoms (30).
The 16 items cover the nine symptom domains of major depression, and are rated on a scale of 0-3.
Total score ranges from 0 to 27, with ranges of 0-5 (normal), 6-10 (mild), 11-15 (moderate), 16-20 (moderate to severe), and 21+ (severe).
|
up to 12 weeks
|
Clinical Global Impression (CGI) Scale
Time Frame: up to 12 weeks
|
The Clinical Global Impression (CGI) scale assesses overall treatment response in psychiatric patients and has good reliability and validity metrics.
The administration time is 2 minutes.
This scale consists of three items: Severity of Illness (item 1); Global Improvement (item 2); and Efficacy Index (item 3).
Item 1 is rated on a seven-point scale (1 = normal, 7 = among the most extremely ill patients) as is item 2 (1 = very much improved, 7 = very much worse).
Full scale is 1 to 14.
|
up to 12 weeks
|
Massachusetts General Hospital Cognitive and Physical Functioning Questionnaire (CPFQ)
Time Frame: At baseline and Visit 6 (week 10)
|
The Massachusetts General Hospital Cognitive and Physical Functioning Questionnaire (CPFQ) is a brief scale to measure cognitive and executive dysfunction in mood and anxiety disorders, and possesses good reliability and validity.
The Massachusetts General Hospital CPFQ was developed to assess each of the 7 most common complaints of depressed patients reporting fatigue or cognitive/executive problems.
The CPFQ consists of 7 questions, each rated on a scale from 1 to 6, with 1 indicating greater than normal functioning, 2 indicating normal functioning and with higher numbers indicating poorer functioning.
Total score range from 7 (greater than normal function) to 42 (poor function).
|
At baseline and Visit 6 (week 10)
|
HAM-A
Time Frame: Baseline and Week 10
|
Change in Hamilton Anxiety Rating Scale (HAM-A) score from baseline to Week 10.
It consists of 14 items, each defined by a series of symptoms.
Each item is rated on a 5-point scale, ranging from 0 (not present) to 4 (severe), with a total score range of 0-56, where <17 indicates mild severity, 18-24 mild to moderate severity and >25-30 moderate to severe.
|
Baseline and Week 10
|
Beck Scale for Suicidal Ideation (BSI)
Time Frame: Baseline and Week 10
|
Mean change in Brief Inventory Symptom from baseline to week 10.
The BSS is a self-report 19-item scale preceded by five screening items.
The BSS and its screening items are intended to assess a patient's thoughts, plans and intent to commit suicide.
All 24 items are rated on a three-point scale (0 to 2).
In this study, scores from the five screening items were included in the overall score.
Therefore, total scores could range from 0 to 48, with higher scores reflecting more severe symptoms.
