Treatment Resistant Geriatric Depression in Primary Care: Is NAAG (N-Acetylaspartylglutamate), Measured by Proton Magnetic Resonance Spectroscopy (1H-MRS) at 3 Tesla, a Predictor of Treatment Response?
This study involves collaboration between McLean Hospital, Geriatric Medicine at the
Cambridge Health Alliance (CHA) and other sites within the Partners and Harvard Medical
School network. The investigators plan to recruit individuals 55 to 89 years old with
treatment resistant depression. Someone with "treatment resistant" depression for this study
may be someone who still has sad or low feelings and thoughts even though he/she is taking
an antidepressant medication for at least 8 weeks to help relieve his/her depression. During
the study, subjects will gradually add memantine hydrochloride in dosages up to 20 mg/day
for 8 weeks to their standard antidepressant treatment.
The investigators are doing this research study to help answer 3 questions:
1. Do older adults with treatment resistant Major Depression have lower levels of a
chemical in the brain called NAAG than older adults without Major Depression?
2. Do older adults with naturally low NAAG levels do better on memantine hydrochloride
treatment than older adults with higher amounts of this chemical on memantine
hydrochloride treatment?
3. Do older adults with treatment resistant depression have more problems with memory and
concentration than older adults without depression?
The investigators are also interested in looking at electrical and neuronal activity of the
brain, spiritual beliefs, and fatigue in relationship to depression.
The investigators hypothesize that:
1. Older individuals with treatment resistant Major Depression will have lower levels of
NAAG compared with age-matched older control subjects.
2. Older adults with treatment resistant depression and low NAAG levels will do better on
treatment with memantine hydrochloride than older adults on memantine with higher NAAG
levels.
3. Older adults with depression will do better on tests of attention and executive
functioning after treatment with memantine hydrochloride.
4. Healthy controls will do better on tests of attention and executive functioning than
older adults with depression.

RESEARCH DESIGN AND METHODS
We will enroll up to 20 subjects with major depression, ages 55-89, and up to 20 healthy
control subjects, ages 55-89 matched with depression group for age, sex, and ethnicity. We
require 10 subjects in each group to have completed the study protocol with clinical and MRI
scan data suitable for analysis.
Subjects in both groups will be recruited from:
- Cambridge Health Alliance (CHA) geriatric medicine group practice.
- Mount Auburn Outpatient programs and affiliates
- Beth Israel Deaconess Medical Center Outpatient programs and affiliates
- McLean Hospital Geriatric Psychiatry Outpatient, Inpatient, and Partial (SAGE - Seniors
Aging Gracefully Everyday) programs
- Other inpatient, partial, and outpatient psychiatry programs at McLean Hospital
- Outpatient programs affiliated with Partners Healthcare and/or Harvard Medical School,
such as:
- Partners Community Health Care primary care physicians (PCPs),
- Massachusetts General Hospital and Brigham and Women's PCP network
- Local geriatricians and community psychiatrists
- General public and community (through IRB-approved local advertisements), such as:
- Public areas (gyms, super markets, etc)
- Retirement communities
- The Harvard Division on Aging
- Newspaper
- Radio
- Internet
- McLean Hospital Geriatric Psychiatry Research Program's research studies, including:
- Subjects who have completed participation in treatment or non-treatment studies
- Subjects who are actively participating in non-treatment research studies
One site (McLean Hospital) is engaged in this protocol. CHA and other sites only refer
subjects to McLean and do not consent subjects or complete any study protocol procedures.
Subjects must meet all selection criteria in order to participate in the study protocol.
All subjects will complete a brief pre-screening interview over the phone or in person in
order to assess their preliminary eligibility for study inclusion.
Screening Period:
After signing consent, all study subjects will follow the same screening period (with the
exceptions for control subjects mentioned below). Screening procedures include a clinical
diagnostic interview, medical monitoring, physical exam, collecting information regarding
prior and concomitant medication and adverse events, blood draw, vital signs, height, and
weight, demographic and clinical history information, as well as assessments of daily
functioning, mood, anxiety, and cognition.
Visit 2 / Baseline (Week 0):
Depression subjects will return to the office after the completion of screening procedures
(within 14 days of signing consent) to complete baseline procedures which include
assessments of daily functioning, fatigue, mood, anxiety, medical monitoring, psychiatric
interview, concomitant medications, adverse events, vitals, 3T scan, EEG with resting state
and Flanker Task procedures (prior to receiving study medication), spirituality
questionnaire, and urine pregnancy test (if applicable). Neuropsychological tests will also
be completed at this visit.
No changes in psychotropic drugs will be allowed for depression subjects during this the
screening period before study drug is administered. The subjects with depression will be
administered (before leaving the office) memantine HCl 5 mg tablets. All depression subjects
will start at a dose of 5 mg once per day in the morning.
Visit 3 (Week 1) and Visit 4 (Week 2):
Following the completion of Visit 2, the subject will return to the office for 2 visits in 2
consecutive weeks. A psychiatric interview, review concomitant medications and AEs (if any),
mood and anxiety scales, monitoring of medication tolerability and compliance, vital sign
collection will be completed at these visits. Study medication will be dispensed and
depression subjects will be instructed according to the dosing schedule.
Visit 5 (Week 4) and 6 (Week 6):
After completing Visit 4, subjects will return to the office 2 weeks later for Visit 5 (Week
4) and then 2 weeks after that for Visit 6 (Week 6). The same visit procedures will be
completed at these visits as Visits 3 and 4, except the subject will not meet with the study
psychiatrist at Visit 6 (Week 6). Subjects may complete Visit 6 in person or over the phone.
Visit 7 (Week 8) Final Study Visit:
After completing 8 weeks on study medication, the subject will return to the office for the
final study visit. This visit will complete the same procedures as Visits 3 through 6 with
the addition of another 3T scan (with a negative urine pregnancy test, if applicable), EEG
(with resting state and Flanker Task) and neuropsychological tests. Participants will also
repeat spirituality and fatigue questionnaires with assistance from study staff.
Subjects will be asked to return all study medication for the final visit. At this time
subjects will have the option of staying on the medication or tapering off study medication
and being referred to the McLean Hospital Geriatric Outpatient Clinic for follow up or to an
appropriate physician of their choice. We will share information regarding study
participation and results with the subjects' primary care physician and/or other entities
only if the subject has completed an "Authorization for Release of Medical Records" form. If
the subjects chose to discontinue treatment with memantine HCl, the psychiatrist (BPF) will
instruct subjects how to safely taper off study medication.
Control Subject Visits:
Following screening, control subjects will return to the office for 3 visits. Unlike the
depression group, the control group will NOT receive the study drug memantine HCl. Control
subjects are not scheduled to meet with the study psychiatrist at the Baseline Week 0 and
Week 8 visits and complete blood draw and one of the neuropsychological tests during
participation. Other than the exceptions previously mentioned, control subjects will follow
the same protocol as the depression subjects for the screening period, Baseline (Week 0),
and Week 8 Visit. Study staff will monitor adverse events (if any occur), use of concomitant
medication (if any), and subject safety throughout study participation. Vital signs will
also be collected at every visit. Mood measures, spirituality and fatigue questionnaires,
and neuropsychological tests identical to those administered to the depression group will be
completed during the Week 8 final visit. Controls will also complete the same 3T MRI
scanning protocol as depression subjects. Controls also have the opportunity to participate
in EEG acquisition at baseline and study endpoint.
Follow-up:
We plan to contact enrolled subjects after the last subject completes the study per protocol
and the data has been analyzed. This follow-up correspondence will consist of at least 3
attempts to contact subjects' by phone and 1 certified letter sharing our research findings
with subjects.
We will enroll up to 20 subjects with major depression, ages 55-89, and up to 20 healthy
control subjects, ages 55-89 matched with depression group for age, sex, and ethnicity. We
