- Primary Outcome Measures
Name Time Method Change From Baseline to 4 Week Endpoint in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score Baseline to Week 4 Measures the overall severity of depressive symptoms. The MADRS has a 10-item checklist. Items are rated on a scale of 0-6, for a total score range of 0 (low severity of depressive symptoms) to 60 (high severity of depressive symptoms).
- Secondary Outcome Measures
Name Time Method Change in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score From Baseline Baseline to Weeks 1, 2, 3, 4, 6, 8 Measures the overall severity of depressive symptoms. The MADRS has a 10-item checklist. Items are rated on a scale of 0-6, for a total score range of 0 (low severity of depressive symptoms) to 60 (high severity of depressive symptoms).
Clinical Global Impression of Improvement (CGI-I) at Each Visit Weeks 1, 2, 3, 4, 6, 8 Measures clinician's perception of patient improvement at the time of assessment compared with the start of treatment. Scores range from 1 (very much better) to 7 (very much worse).
Evaluation of Rescue Options Based on Changes in the Montgomery-Asberg Depression Rating Scale (MADRS) and the 6-Item Hamilton Depression Scale (HAMD-6) 4 to 8 weeks Changes in Montgomery-Åsberg Depression Rating Scale (MADRS) and 6-Item Hamilton Depression Scale (HAMD-6) total scores were evaluated following dose up-titration in those patients who did not achieve the minimum 50% response for primary endpoint. MADRS is a rating scale for severity of depressive mood symptoms. Total scores range from 0 (low severity of symptoms) to 60 (high severity of symptoms). The HAMD-6, derived by the sum of HAMD-17 items 1, 2, 7, 8, 10 and 13, evaluates "core" symptoms of Major Depressive Disorder (MDD). Total subscale scores range from 0 (normal) to 22 (severe).
Number of Patients With Potentially Clinically Significant Laboratory Findings over 8 weeks Laboratory results that were potentially clinically significant.
Change in 6-Item Hamilton Depression Scale (HAMD-6) Total Scores From Baseline Baseline to Weeks 1, 2, 3, 4, 6, 8 The HAMD-6 (Items 1,2,7,8,10,13 from the 17-item HAMD) evaluates "core" symptoms of Major Depressive Disorder (MDD). Total scores range from 0 (normal) to 22 (severe).
Clinical Global Impression of Severity (CGI-S) Scores at Each Visit Baseline, Weeks 1, 2, 3, 4, 6, 8 Measures severity of illness at the time of assessment compared with start of treatment. Scores range from 1 (normal, not at all ill) to 7 (among the most extremely ill patients).
Percentage of Responders 4 to 8 weeks Patients with reduction in MADRS score ≥50% after 4 weeks were to stay on previous dose of duloxetine. Those with reduction in MADRS \<50% were to receive 120 mg for remaining 4 weeks of treatment (up-titration from 60 mg to 120 mg for those randomized to 60 mg, and addition of placebo to 120 mg dose for those randomized to 120 mg). However, 2/70 patients randomized to 60 mg and then up-titrated to 120 mg after 4 weeks had reduction in MADRS ≥50% after 4 weeks, and 3/64 patients randomized to 120 mg and then given placebo in addition after 4 weeks had reduction in MADRS ≥50% after 4 weeks.
Utilization of Allowed Hypnotic and/or Anxiolytic Co-Medication over 8 weeks Number of participants using medication for anxiety and sleep disturbances.
Number of Participants Experiencing High Values for Vital Signs at Any Time During the Study over 8 weeks Systolic and diastolic blood pressure and pulse rate were measured after 2 minutes rest in a supine position. High values were: diastolic blood pressure ≥90 mm Hg and increase from baseline of ≥10 mm Hg; systolic blood pressure ≥140 mm Hg and increase from baseline of ≥10 mm Hg; pulse rate ≥100 beats per minute (bpm) and an increase of ≥10 bpm from baseline.
Patient Global Impression of Improvement (PGI-I) Score at Each Visit Weeks 1, 2, 3, 4, 6, 8 A scale that measures the patient's perception of improvement at the time of assessment compared with the start of treatment. The score ranges from 1 (very much better) to 7 (very much worse).
Hamilton Anxiety Scale (HAMA) Score at Baseline and Weeks 4 and 8 Baseline and Weeks 4 and 8 The HAMA scale measures anxiety symptoms accompanying Major Depressive Disorder (MDD). Each item of the 14-item HAMA was scored from 0 (not present) to 4 (very severe), with a resulting maximum total score of 56.
Patients Reaching Remission Week 8 Major Depressive Disorder remission was defined as a total MADRS score ≤12 at Week 8.
Reason for Living (RFL) Questionnaire Mean Scores at Baseline and Week 8 Baseline and Week 8 The RFL questionnaire is an instrument that evaluates patient's reasons for not committing suicide using a 6-point rating scale, where 1 is "not at all important" and 6 is "extremely important". The questionnaire required participants to rate how important each item would be for living, if suicide was contemplated. Mean scores could range from 0 to 6.
Change From Baseline to Week 4 and Week 8 in Weight Baseline to Weeks 4 and 8 Change in weight = Post-baseline visit minus baseline.
Discontinuations Due to Adverse Events (AE) over 8 weeks Listing of adverse events (AE) that led to treatment discontinuation (DC).
