Clinical Trial Summary

This study investigates two different approaches to the change in antidepressant treatment when an initial treatment is not effective: early intervention or delayed intervention.

Two hypothesis will be tested:

1. that time to confirmed response is shorter in the early intervention strategy vs. delayed intervention strategy

2. that the time to confirmed remission is shorter in the early intervention strategy compared to delayed intervention strategy.

2. Participants (receiving or not antidepressant treatment) who, based on investigator criteria, initiate treatment with escitalopram or change their current Alzheimer's Disease (AD) treatment to escitalopram for this current MDD episode, at the initial visit.

3. Must have a baseline score of = 19 on the 17-item Hamilton Depression Rating Scale (HAMD-17) at the initial visit.

4. Must have a baseline score of = 4 in the Clinical Global Impression-Severity Scale (CGI-S) at the initial visit.

5. Have a level of understanding sufficient to provide Informed Consent Document (ICD), and to communicate with the investigators and site personnel.

11. Are demonstrating a response or demonstrated a response to the AD treatment for the current depression episode previous to baseline visit.

12. Are investigator site personnel directly affiliated with this study and/or their immediate families. "Immediate family" is defined as a spouse, parent, child, or sibling, whether biological or legally adopted.

13. Are employed by Lilly or Boehringer Ingelheim (BI) (that is, employees, temporary contract workers, or designees responsible for the conduct of the study).

15. Have received treatment within the last 30 days with a drug that has not received regulatory approval for any indication at the time of study entry.

16. Are judged to be at serious suicidal risk in the opinion of the investigator, and/or if the participant's baseline (Visit 1) HAMD-17 scores on item 3 suicide are 3.

18. Require initiation or discontinuation of psychotherapy within 6 weeks prior to enrollment (Visit 1) or at any time during the study.

19. Have any contraindication for the use of duloxetine based on Duloxetine Summary of Product Characteristics (SPC) or any contraindication for the use of escitalopram based on Escitalopram SPC.

20. Have a history of lack of response to duloxetine or escitalopram at a clinically appropriate dose for a minimum of 4 weeks, or have previously completed or withdrawn from this study or any other study investigating duloxetine or escitalopram.

21. Have any previous diagnosis of bipolar disorder, schizophrenia, or other psychotic disorders.

22. Have DSM-IV-defined history of substance abuse or dependence within the past year, excluding nicotine and caffeine.

23. Have serious or unstable cardiovascular, hepatic, renal, respiratory or hematological illness; symptomatic peripheral vascular disease; or other medical (including unstable hypertension and not clinically euthyroid) or psychological conditions that, in the opinion of the investigator, would compromise participation or be likely to require hospitalization during the course of the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to Confirmed Response by = 50% Change From Baseline Reduction in the Hamilton Depression Rating Scale-17 Items (HAMD-17)	Time to confirmed response is defined as the time from the day of study randomization (Visit 2) to the date of first observation of confirmed response defined as = 50% baseline score reduction on the HAMD-17 for 2 consecutive visits. The 17-item HAMD measures depression severity. Each item was evaluated and scored using either a 5-point scale, e.g. absent, mild, moderate, severe, very severe) or a 3-point scale (e.g. absent, mild, marked). The total score of HAMD-17 may range from 0 (normal) to 52 (severe).	Week 4 through Week 16	No
Primary	Estimated Probability of Not Reaching Confirmed Response at 12 Weeks Based on the Survival Function for the Time to Confirmed Response	Survival function is estimating the probability of participants not achieving confirmed response after 12 weeks. Confirmed response is defined as >=50% change from baseline reduction in the Hamilton Depression Rating Scale-17 Items (HAMD-17). The 17-item HAMD measures depression severity. Each item was evaluated and scored using either a 5-point scale (e.g. absent, mild, moderate, severe, very severe) or a 3-point scale (e.g. absent, mild, marked). The total score of HAMD-17 may range from 0 (normal) to 52 (severe).	Week 4 through Week 16	No
Primary	Time to Confirmed Remission by a Hamilton Depression Rating Scale-17 Items (HAMD-17) Score of = 7 That is Maintained for Two Consecutive Visits	Time to confirmed remission is defined as the time from the day of study randomization (Visit 2) to the date of first observation of confirmed remission defined as a score on the HAMD-17 of = 7 for 2 consecutive visits. The 17-item HAMD measures depression severity. Each item was evaluated and scored using either a 5-point scale (e.g. absent, mild, moderate, severe, very severe) or a 3-point scale (e.g. absent, mild, marked). The total score of HAMD-17 may range from 0 (normal) to 52 (severe).	Week 4 through Week 16	No
Primary	Estimated Probability of Not Reaching Confirmed Remission at 12 Weeks Based on the Survival Function for the Time to Confirmed Remission	Survival function is estimating the probability of participants not achieving confirmed remission. Confirmed remission is defined as a Hamilton Depression Rating Scale-17 Items (HAMD-17) Score of = 7 that is maintained for two consecutive visits. The 17-item HAMD measures depression severity. Each item was evaluated and scored using either a 5-point scale (e.g. absent, mild, moderate, severe, very severe) or a 3-point scale (e.g. absent, mild, marked). The total score of HAMD-17 may range from 0 (normal) to 52 (severe).	Week 4 through Week 16	No
Secondary	Time to Confirmed Response as Defined by = 50% Reduction From Baseline Reduction in the 16-Item Quick Inventory of Depressive Symptomatology Self Report (QIDS16SR) That is Reported for Two Consecutive Visits	Time to confirmed response is defined as the time from the day of study randomization (Visit 2) to the date of first observation of confirmed response. QIDS16SR is a 16-item participant-rated measure of depressive symptomatology. The total score ranges from 0 to 27 with higher scores indicative of greater severity.	Week 4 through Week 16	No
Secondary	Time to Confirmed Remission as Defined by a 16-Item Quick Inventory of Depressive Symptomatology Self Report (QIDS16SR) Score of = 5 That is Maintained for Two Consecutive Visits.
