Trial Outcomes & Findings for A Study of Patients With Major Depressive Disorder and Residual Apathy (NCT NCT00985504)

NCT ID: NCT00985504

Last Updated: 2011-12-13

Results Overview

The AES-C is a validated 18-item instrument used to assess cognitive, behavioral, emotional and other symptoms of apathy. Clinicians rate each item based on verbal and nonverbal information provided by the participant. Item scores range from 1 (not at all characteristic) to 4 (a lot characteristic). Total scores range from 18 to 72 where higher derived scores indicate more severe apathy. The Least Squares (LS) Mean Value was calculated from a mixed model repeated measures (MMRM) model with terms of treatment, pooled investigator, visit, treatment\*visit, baseline, and baseline\*visit.

Participant Flow

Acute treatment period (1 week): Participants randomized to switch to 60 milligrams (mg) duloxetine once daily (QD) by mouth (po) or 10 mg escitalopram QD po. Optimization period (7 weeks): Participants given duloxetine or escitalopram in acute study period may optimize their QD po doses (60-120 mg duloxetine QD po; 10-20 mg escitalopram QD po).

Timeframe: Baseline, 8 weeks

Population: All randomized participants with a baseline and at least 1 post-baseline result.

The AES-C is a validated 18-item instrument used to assess cognitive, behavioral, emotional and other symptoms of apathy. Clinicians rate each item based on verbal and nonverbal information provided by the participant. Item scores range from 1 (not at all characteristic) to 4 (a lot characteristic). Total scores range from 18 to 72 where higher derived scores indicate more severe apathy. The Least Squares (LS) Mean Value was calculated from a mixed model repeated measures (MMRM) model with terms of treatment, pooled investigator, visit, treatment\*visit, baseline, and baseline\*visit.

Population: All randomized participants with a baseline and at least 1 post-baseline result.

AES-C subscales separately assess participants' intensity of cognitive, behavioral, emotional, and other apathy symptoms with individual item scores of 1 (not at all characteristic) to 4 (a lot characteristic). Subtotal score ranges for the subscales are: 8-32 (cognitive), 5-20 (behavioral), 2-8 (emotional), and 3-12 for other (display of personal insight, initiative and motivation). Higher subscale scores indicate greater illness severity. The LS Mean Value was calculated from an MMRM model with terms of treatment, pooled investigator, visit, treatment\*visit, baseline, and baseline\*visit.

RSAT assesses symptoms of apathy or decreased motivation among depressed participants who have achieved symptomatic remission with antidepressant treatment and consists of 6 self-report items assessing energy level, motivation and interest, cognitive functioning, weight gain, sleep and sexual functioning, as well as affect. Each item score ranges from 0 to 4 with total scores ranging from 0 to 28. Higher scores indicate greater disease severity. LS Mean Value was calculated from an MMRM model with terms of treatment, pooled investigator, visit, treatment\*visit, baseline, and baseline\*visit.

The PGI-I is a scale that measures the participant'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). The LS Mean Value was calculated from an MMRM model with terms of treatment, pooled investigator, visit, and treatment\*visit.

MADRS is a rating scale for severity of depressive mood symptoms and 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). Item 8 assesses the participant's inability to feel. Scores range from 0 (normal interest in surroundings and other people) to 6 (emotional paralysis, inability to feel anger/grief/pleasure). The LS Mean Value was calculated from an MMRM model with terms of treatment, pooled investigator, visit, treatment\*visit, baseline, and baseline\*visit.

The MGH-CPFQ is a 7-item participant-rated questionnaire evaluating the participant's cognitive and physical well-being during the past month. The MGH-CPFQ assesses motivation, wakefulness, energy, focus, recall, word-finding difficulty, and mental acuity. Each item is scored on a 6-point scale ranging from 1 ("greater than normal") to 2 ("normal") to 6 ("totally absent"). Total scores range from 7 to 42. Higher scores indicate greater disease severity. The LS Mean Value was calculated from an analysis of covariance (ANCOVA) model with terms of treatment, pooled investigator, and baseline.

The SDS is a participant-rated assessment. Total scores range from 0-30 with higher values indicating greater disruption in the participant's work/social/family life. Items 1-3 assess the effect of the participant's symptoms on work/school schedule, social life/leisure activities, and family life/home responsibilities, respectively. Item scores are 0-10; higher values indicate greater disruption. Number of unproductive days and days lost in past week (symptom related) were reported. LS Mean Value was calculated from an ANCOVA model with terms of treatment, pooled investigator, and baseline.

Relapse is defined as achieving a Montgomery-Asberg Depression Rating Scale (MADRS) total score≥16 at any time after baseline. The MADRS is a rating scale for severity of depressive mood 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).

Escitalopram
n=237 Participants
Participants received 10 mg of escitalopram QD po for 1 week (Acute Treatment Period) followed by 10-20 mg QD po for the remaining 7 weeks (Optimization Period), with an option to continue treatment for an additional 2 weeks.
Percentage of Participants Who Relapsed During 8 Weeks
11.9 percentage of participants
11.0 percentage of participants

SECONDARY outcome

Timeframe: Baseline through 8 weeks

Population: Number of participants in each treatment group having time to relapse plus the participants censored. Duloxetine had 200 participants censored and escitalopram had 199 participants censored.

The number of days from baseline to the first relapse is defined as reaching a MADRS Total Score≥16. 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). Censored participants were included in the Kaplan-Meier analysis, the minimum and maximum time to relapse have been calculated and reported here. Median time to relapse and quartiles could not be computationally calculated using the Kaplan-Meier procedure due to low event rate and high completion rate (censored).
