A Study Comparing the Efficacy and Safety of Duloxetine and Placebo for the Treatment of Depression in Elderly Patients

Duloxetine Versus Placebo in the Long-Term Treatment of Patients With Late-Life Major Depression

The purpose of this study is to compare the efficacy and safety of duloxetine 60 mg once daily to placebo on depression in elderly patients (greater than or equal to 65 years of age). Patients who do not respond in the first 13 weeks will be eligible for rescue using pre-defined criteria. Patients randomized to duloxetine 60 mg/day meeting the rescue criteria will be increased to 120 mg/day. Patients randomized to the placebo arm meeting the rescue criteria will be assigned to duloxetine 60 mg/day.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline to 13 Weeks in Hamilton Depression Rating Scale (HAMD-17) Maier Subscale	The Maier subscale (Items 1,2,7,8,9,10) represents symptoms of depression. Total subscale scores range from 0 (normal) to 24 (severe).	baseline (Week 1), Week 13

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline on the 30-item Geriatric Depression Scale (GDS)	The 30-item Geriatric Depression Scale (GDS) is a self-administered test of 30 questions to measure the severity of depression. The yes/no questions result in a range of scores from 0 (normal) to 30 (severe depression).	baseline (Week 1), Week 13, Week 25
Change From Baseline in the HAMD-17 Total Score, Subscales, and Individual Items	Total Score assess depression severity (scores 0-52). Core, Maier and Bech subscales assess symptoms of depression (scores:0-20=Core; 0-24=Maier; 0-22=Bech). Anxiety/Somatization subscale assesses severity of anxiety (0-18). Retardation subscale assesses dysfunction in mood and work (0-14). Sleep subscale assesses insomnia (0-6). Individual item scores may range from 0-4 or 0-2. Higher numbers indicate more severe symptoms.	baseline (Week 1), Week 13, Week 25
Change From Baseline in the Brief Pain Inventory (BPI) Severity and Interference Scores	The Brief Pain Inventory (severity and interference scales) (BPI) is a self-reported scale that measures the severity of pain and the interference of pain on function. Severity scores: 0 (no pain) to 10 (severe pain) on each question assessing worst pain, least pain, and average pain in past 24 hours, and pain right now. Interference scores: 0 (does not interfere) to 10 (completely interferes) on each question assessing interference of pain in past 24 hours for general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life.	baseline (Week 1), Week 13, Week 25
Change From Baseline in the Numeric Rating Scales (NRS) for Pain Item Scores	Numeric Rating Scales (Semantic Differential Scales) for Pain are 6 self-administered scales that assesses experience of overall pain, back pain, headache, shoulder pain, time in pain while awake, and pain interference with daily activities, during the past week. Each item is scored on a numeric 11-point semantic differential scale (0-10) from 0 = no pain to 10 = pain as severe as you can imagine; or 0 = none of the time to 10 = all of the time; or 0 = no interference to 10 = unable to do any activities at all.	baseline (Week 1), Week 13, Week 25
Patient's Global Impression of Improvement (PGI-I) at 13 Weeks and 25 Weeks	The PGI-Improvement scale is a patient-rated instrument that measures perceived improvement in symptoms. It is a 7-point scale where a score of 1 indicates that the patient is "very much improved," a score of 4 indicates that the patient has experienced "no change," and a score of 7 indicates that the patient is "very much worse."	Week 13, Week 25
Change From Baseline in the Clinical Global Impression-Severity (CGI-S)	Measures severity of illness at the time of assessment. Scores range from 1 (normal, not at all ill) to 7 (among the most extremely ill patients).	baseline (Week 1), Week 13, Week 25
Change From Baseline in the Mini-Mental State Exam (MMSE)	Mini-Mental State Examination (MMSE)is a widely used rating measure of cognitive ability. Scores range from 0 to 30. The MMSE will be used to categorize patients as with or without dementia. Higher number indicates better cognitive ability. Patients with a MMSE score of 20 to 23 will be categorized as having mild dementia, while those with a score of ≥ 24 will be categorized as having no dementia.	baseline (Week 1), Week 9, Week 25
Change From Baseline in the Quality of Life, Enjoyment, and Satisfaction Questionnaire (Q-LES-Q-SF)	The Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q-SF) measures the degree of enjoyment and satisfaction experienced in various areas of daily life. The short version is a self-administered 16 item scale evaluating satisfaction of general activities on a 5-point Likert scale that indicates the degree of enjoyment or satisfaction achieved during the past week (1 = very poor and 5 = very good).	baseline (Week 1), Week 13, Week 25
Probability of Remission as Measured by the HAMD-17 Total Score ≤7 and ≤10	Remission (visitwise binary outcome, yes/no) is defined as HAMD-17 Total Score ≤7 and ≤10. HAMD-17 measures depression severity. The total score can range from 0 (normal) to 52 (severe depression). The visitwise probability of patients meeting criteria for remission (either Total Score ≤7 or ≤10) was analyzed using a categorical, pseudo-likelihood-based repeated measures approach. This analysis included the fixed, categorical effects of treatment, investigator, visit, and treatment-by-visit interaction, as well as the continuous, fixed covariate of baseline score.	Week 13, Week 25
Probability of Response at Endpoint as Measured by ≥50% Improvement in the HAMD-17 Total Score	Response (visitwise binary outcome, yes/no) is defined as ≥ 50% reduction from baseline in the HAMD-17 total score. HAMD-17 measures depression severity. The total score can range from 0 (normal) to 52 (severe depression). The visitwise probability of patients meeting criteria for response was analyzed using a categorical, pseudo-likelihood-based repeated measures approach. This analysis included the fixed, categorical effects of treatment, investigator, visit, and treatment-by-visit interaction, as well as the continuous, fixed covariate of baseline score.	Week 13, Week 25
Probability of Remission as Measured by the HAMD-17 Total Score ≤7 and ≤10 by Medical Comorbidity Severity as Assessed by the Cumulative Illness Rating Scale-Geriatric Version (CIRS-G)	Remission defined as HAMD-17 Total Score ≤7 and ≤10. HAMD-17 measures depression severity. Total score ranges: 0 (normal) to 52 (severe depression). Visitwise probability of patients achieving remission was analyzed using a categorical, pseudo-likelihood-based repeated measures approach. CIRS-G evaluates 14 organ-specific categories using a rating strategy of 0=no problems; 1=current mild problem/past significant problem; 2=moderate disability/morbidity; 3=severe/constant significant disability; and 4=extremely severe/immediate treatment required/end organ failure. Total score ranges: 0 to 56.	Week 13, Week 25
Probability of Efficacy Onset as Measured by at Least 20% Sustained Reduction From Baseline in the HAMD-17 Maier Subscale at Week 3	Patients are considered to have met onset (visitwise binary outcome, yes/no) criteria at a particular visit if they had at least 20% reduction from baseline in the HAMD-17 Maier subscale at that visit and at all subsequent visits in the acute phase. Maier subscale measures core symptoms of depression and scores range from 0 (normal) to 24 (severe). The visitwise probability of patients meeting onset criteria was analyzed using a categorical, pseudo-likelihood-based repeated measures approach.	Week 3

A patient has a treatment-emergent elevated supine pulse if the value is ≥100 with an increase ≥10 from baseline. A patient has abnormal weight change if the gain or loss is ≥7% compared to baseline.	Baseline (Week 1) through Week 25
Number of Participants Experiencing Sustained Hypertension (SH) or Orthostatic Hypotension (OH)	Sustained Hypertension is defined as supine systolic BP >= 140 (or diastolic BP >= 90) mm Hg and increase from baseline (highest value in baseline visit interval) >= 10 mm Hg for 3 or more consecutive visits in postbaseline visit interval. Orthostatic Hypotension is defined as standing diastolic BP at least 10 mm Hg less than the supine diastolic BP or the standing systolic BP at least 20 mm Hg less than the supine systolic BP at any time in postbaseline visit interval and a patient does not meet this criterion at any visit in baseline interval.	baseline (Week 1) through Week 25
