Brain Aging and Treatment Response in Geriatric Depression
October 11, 2019 updated by: Helen Lavretsky, MD, University of California, Los Angeles
Treatment of Geriatric Depression With Mild Cognitive Impairment: A Double-blind Placebo-Controlled Trial of Namenda (Memantine) Augmentation of Lexapro (Escitalopram) in Depressed Patients at Least 60 Years of Age
The proposed project will evaluate the role of neuroimaging biomarkers of brain aging (i.e., neurodegenerative and vascular brain changes) and mild cognitive impairment in the patterns of treatment response to memantine combined with escitalopram compared to escitalopram and placebo.

Detailed Description
This study is designed to conduct a double-blind placebo-controlled trial of Namenda (Memantine) as an augmentation to Lexapro (Escitalopram) in depressed older adults 60 years of age and older.
Throughout the course of the study, the investigators anticipate screening about 400 subjects to recruit 134 participants in the first four years.
This study will require that the subjects complete up to 20 (twenty) visits in 12 (twelve) months to the study site during their participation.
The purpose of this study is to determine whether Namenda (memantine) when taken in combination with Lexapro (escitalopram), may improve the quality of treatment response by making it faster and more complete, and also by improving thinking and memory in comparison to Lexapro taken with a placebo.
Enrolled subjects will be provided with 10-20 mg of escitalopram for 12 months, and concurrently randomly assigned to either memantine or placebo groups.
The investigators will also examine the safety and tolerability (how well the treatment works and the side effects) of a combination of Namenda and Lexapro as compared to placebo and Lexapro in subjects with major depressive disorder and mild cognitive impairment who are at least 60 years of age.
Memantine is likely to accelerate and enhance antidepressant response to escitalopram and improve cognitive performance.
Subjects with amnestic mild cognitive impairment or biomarkers of brain aging at baseline are likely to have preferential response to the combination of memantine and escitalopram compared to escitalopram and placebo, thus identifying a more personalized treatment approach in the high-risk subgroups for poor clinical outcomes.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Escitalopram and Memantine
Participants will take a combination of Escitalopram and Memantine for 12 months
|
All subjects will receive 10 to 20mg of escitalopram open-label throughout the trial.
Participants will begin taking one 10mg capsule once per day, and this dosage may be increased or decreased depending on the participant's response to the medication.
Participants will continue on their assigned dosage of escitalopram until treatment completion.
Other Names:
Memantine dosage will be 5 to 20mg a day.
Participants will initially take one 5mg capsule once a day, which will be gradually increased to a maximum of 10mg capsules twice per day.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Hamilton Depression Rating Scale
Time Frame: Measured at 3 months; 6 months and 12 months
|
Clinician administered scale measures severity of depressive symptoms.
This measure includes 24 items.
Response options vary item to item and include the following ranges: [0-2], [0-3], and [0-4].
A score of 0 suggests absence of symptoms and/or difficulties and higher scores represent more severe difficulties.
Possible overall score range [0-74], higher scores representing more severe difficulties.

Measured at 3 months; 6 months and 12 months

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Montgomery Asberg Depression Rating Scale
Time Frame: Measured at 3 months; 6 months and 12 months
|
Clinician administered item scale measures severity of depressive symptoms.
The 10 items are measured on a 7-point scale ranging from 0 to 6; creating a total range of 0-60.
A score of 0 suggests absence of symptoms and higher scores represent greater severity of depression.Severity gradations for the MADRS have been proposed (9-17 = mild, 18-34 = moderate, and ≥ 35 = severe).
Treatment remission is defined as an endpoint total score ≤ 10.
|
Measured at 3 months; 6 months and 12 months
|
Change in Cognitive Domain Scores
Time Frame: Measured at 6 months and 12 months
|
Neuropsychological battery of tests which included the following domains: learning, delayed recall, and executive functioning.
Raw scores were transformed to z-scores for each test score of interest for each participant, and then averaged.
These z-scores were averaged within each neuropsychological domain to produce composite scores and then averaged over all tests to calculate a global performance score.
Higher scores are indicative of better performance.

Measured at 6 months and 12 months

Measure Description |
Time Frame |
---|---|---|
Number of Participants With Adverse Events
Time Frame: Measured at 3, 6 months and 12 months
|
The UKU (Udvalg for Kliniske Undersogelser) Side Effect Rating Scale organizes symptoms into 4 categories (i.e., Psychic, Neurologic, Autonomic, Other) containing 8-19 symptoms each.
Each symptom receives a score for degree and causal relationship.
Degree is scored between 0-3 with higher scores being more severe.
Causal relationship is scored as improbable, possible, or probable.
