NCT00177671

Brief Summary

This study will determine the effectiveness of combining escitalopram, venlafaxine, or duloxetine with donepezil, a medication used in Alzheimer's disease, in improving memory, concentration, attention, and problem solving abilities, and reducing the risk of depressive relapse in older individuals with depression.

Outcome Measures

Primary Outcomes (3)

  • Global Cognitive Performance

    Cognitive performance was assessed with 17 well established and validated individual tests measuring multiple domains. We transformed raw scores for individual tests into Z-scores using the baseline distribution of a non-depressed, cognitively normal, older adult comparison group (N=36)of similar age, education, and medical health recruited concurrently with the depressed participants. These Z-scores were averaged within each neuropsychological area to produce domain scores and then averaged over all 17 tests to calculate a global cognition performance score.

    Measured at baseline and Years 1 and 2 in maintenance

  • Cognitive Instrumental Activities of Daily Living (IADL)

    The PASS (a performance-based assessment of instrumental activities of daily living)generates a composite measure of 13 cognitive IADL items capturing performance on activities such as shopping, bill paying, medication management, and home safety. We report the percentage of subjects at each assessment point adjudged to have independent functioning. This was determined by a clinician rater observing subjects perform each task and rating them according to predetermined criteria on a 4 point scale, ranging from 0 (unable) to 3 (independent).

    baseline, year 1 and year 2

  • Number of Participants With Recurrence of Major Depression

    Recurrence of major depressive episodes as determined by SCID/DSM IV: two weeks of low mood and/or anhedonia, together with at least five of the following symptoms: suicidal ideation, low energy, sleep disturbance, appetite disturbance, psychic anxiety or somatic anxiety. In addition, a diagnosis of major depression requires evidence of distress or impairment.

Study Arms (2)

1

EXPERIMENTAL

escitalopram plus donepezil (DNP)in the experimental maintenance phase of the study. For subjects failing to respond to escitalopram during the initial open phase of acute treatment we allowed the use of duloxetine or venlafaxine to bring about remission and establish eligibility for randomized assignment to maintenance treatment with augmentation donepezil. Participants remained on the same antidepressant medication and dosage throughout the 2 year maintenance phase of the study. In the event of a recurrence of major depression during maintenance treatment, dosages of antidepressant medication were raised, or the antidepressant was switched to venlafaxine or duloxetine. For subjects failing to respond to escitalopram during the initial open phase of acute treatment, we allowed the use of duloxetine to bring about remission and establish eligibility for randomized assignment to maintenance treatment with augmentation placebo.

Drug: EscitalopramDrug: DonepezilDrug: VenlafaxineDrug: Duloxetine

PLACEBO COMPARATOR

escitalopram plus placebo (PBO) in the experimental maintenance phase of the study. For subjects failing to respond to escitalopram during the initial open phase of acute treatment, we allowed the use of duloxetine or venlafaxine to bring about remission and establish eligibility for randomized assignment to maintenance treatment with augmentation placebo. Participants remained on the same antidepressant medication and dosage throughout the 2 year maintenance phase of the study. In the event of a recurrence of major depression during maintenance treatment, dosages of antidepressant medication were raised, or the antidepressant was switched to venlafaxine or duloxetine. For subjects failing to respond to escitalopram during the initial open phase of acute treatment, we allowed the use of venlafaxine or duloxetine to bring about remission and establish eligibility for randomized assignment to maintenance treatment with augmentation placebo.
