Detailed Description
The Apathy in Dementia Methylphenidate Trial (ADMET), funded by the National Institute of Aging, is a Phase II, placebo-controlled, masked, 3-center randomized clinical trial. ADMET will enroll 60 patients with Alzheimer's disease (AD) and significant apathy from outpatient, nursing home, and assisted living facilities along with their primary caregiver. Eligible and willing patients will be randomly assigned to methylphenidate (20 mg per day) or placebo. At baseline and each in-person follow-up visit, all caregivers and patients will be provided with a standardized psychosocial intervention consisting of a counseling session, provision of educational materials, and 24-hour availability for crises. Efficacy and safety outcomes will be measured at baseline and at in-person follow-up visits at 2, 4, and 6 weeks following randomization. Telephone contact will take place at 1, 3, and 5 weeks after randomization.
ADMET has 80% power to detect a difference of at least 3.3 in change in the Apathy Evaluation Scale scores between the two treatment groups. It also has 80% power to detect an absolute difference of 35% or more in the change in the proportion of study participants improving on te Clinical Global Impression of Change, given that 20% to 305 of participants in the placebo group show improvement.

- Sufficient fluency, of both the patient and caregiver, in written and spoken English to participate in study visits, physical exams, and outcome assessments
- No change to AD medications within the month preceding randomization, including starting, stopping, or dosage modifications
- Treatment with stable doses of selective serotonin reuptake inhibitor antidepressants(SSRIs) is appropriate if stable for 3 months prior to randomization. Other psychotropics(with the exclusion of antipsychotics), if stable for 3 months, may be allowed only with Steering Committee approval on a case by case basis.
Exclusion criteria:
- Meets criteria for Major Depressive Episode, by Diagnostic Statistical Manual of Mental Disorder - IV (TR) criteria
- Clinically significant agitation /aggression for which either 1) the frequency of agitation /aggression as assessed by the NPI is 'Very frequently', or 2) the frequency of agitation /aggression as assessed by the NPI is 'Frequently' AND the severity of the agitation as assessed by the NPI is 'Moderate', or 'Marked'
- Clinically significant delusions for which either 1) the frequency of delusions as assessed by the NPI is 'Very frequently', or 2) the frequency of delusions as assessed by the NPI is 'Frequently' AND the severity of the delusions as assessed by the NPI is 'Moderate', or 'Marked'

- Treatment with psychotropic medications in the 2 weeks prior to randomization with the exception of approved treatments for dementia (ChEIs and memantine), selective serotonin reuptake inhibitor antidepressants, and trazodone (if used as an aid to facilitate sleep and not as an antidepressant); other psychotropics (with the exclusion of antipsychotics), if stable for 3 months, may be allowed only with Steering Committee approval on a case by case basis. Note that antipsychotics are expressly prohibited.
- Treatment with methylphenidate is contraindicated in the opinion of the study physician
- Failure of treatment with methylphenidate in the past for apathy after convincing evidence of an adequate trial as judged by study physician
- Treatment with a medication that would prohibit the safe concurrent use of methylphenidate such as monoamine oxidase inhibitors and tricyclic antidepressants
- Need for acute psychiatric hospitalization or is suicidal
- Uncontrolled hypertension (medication non-compliance or past 3 months with a diastolic reading of 105 as verified by compartment pressure of the rectus sheath (CPRS))
- Symptomatic coronary artery disease deemed to be significant by study physician at the time of screening
- Lack of appetite that results in significant unintentional weight loss as determined by the study physician in the last three months
- Significant communicative impairments
- Current participation in a clinical trial or in any study that may add significant burden or affect study outcomes
- Hyperthyroidism, advanced arteriosclerosis, symptomatic cardiovascular disease, serious structural cardiac abnormalities, cardiomyopathy, serious heart rhythm abnormalities, or a family history of sudden death or death related to heart problems
- Glaucoma, pheochromocytoma, or known or suspected hypersensitivity to methylphenidate or its excipients
- Central Nervous System (CNS) abnormalities (e.g., cerebral aneurysm) and/or other vascular abnormalities such as vasculitis or pre-existing stroke, motor tics or a family history or diagnosis of Tourette's syndrome, seizures (convulsions, epilepsy), or abnormal EEGs
- Any condition that, in the opinion of the study physician, makes it medically inappropriate or risky for the patient to enroll in the trial

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Methylphenidate
Methylphenidate, target dose 20 mg per day (range 10-20 mg per day) and psychosocial intervention
|
The target dose is 20 mg per day provided as two 10 mg doses administered orally.
Patients will start by taking 10 mg daily (two 5 mg over-encapsulated tablets) for three days, at which time the dose will be increased to 20 mg per day (four 5 mg over-encapsulated tablets).
In the event of significant side-effects, the dose will be reduced to a minimum of 10 mg per day.
The study drug will be administered for 6 weeks.
Other Names:
The psychosocial intervention will consist of three components: a counseling session, the provision of education materials, and 24-hour availability for crises. The counseling session, in which a trained study clinician will counsel the primary caregiver, lasts approximately 20-30 minutes, and consists of the following elements:
The educational materials will consist of a copy of the book The 36-Hour Day |

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Apathy Evaluation Scale (AES)
Time Frame: baseline to 6 weeks
|
Change in score of Apathy Evaluation Scale from baseline to 6 weeks; the minimum score is 18; the maximum score is 72.
Higher scores indicate more severe apathy.
|
baseline to 6 weeks
|
Alzheimer's Disease Cooperative Study- Clinical Global Impression of Change
Time Frame: baseline to 6 weeks
|
Proportion of individuals improving on Alzheimer's Disease Cooperative Study- Clinical Global Impression of Change (CGIC) from baseline to 6 weeks; the CGIC is a 7-point Likert scale used to rate each patient with the following scores: "marked worsening"(7), "moderate worsening" (6), "minimal worsening"(5), "no change"(4), "minimal improvement"(3), "moderate improvement"(2), "marked improvement"(1).
Ratings were based on an interview with the caregiver and an examination of the patient.
The CGIC requires the clinician to consider a number of aspects of apathy, such as level of initiative, level of interest, and emotional engagement.

baseline to 6 weeks

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Digit Span
Time Frame: baseline and 6 weeks
|
Change in Digit Span from baseline to 6 weeks.
The Wechsler Adult Intelligence Scale - Revised Digit Span is used to assess auditory attention and working memory.
Both forward and backward span is assessed.
Both tests consist of six number sequences that the psychometrist reads aloud one at a time.
After each sequence is read, the participant must repeat the digits back in the same (forward) or reverse (backward) order.
Scores range from 0 to 16, with higher numbers indicate better functioning.
|
baseline and 6 weeks
|
Mini-Mental State Exam (MMSE)
Time Frame: baseline and 6 weeks
|
Change in Mini-Mental State Exam score from baseline to 6 weeks; this cognitive test estimates of dementia severity.
Domains included orientation, memory, working memory, naming, following verbal and written commands, spontaneously writing a sentence, and copying two overlapping pentagons.
The minimum MMSE score is 0; the maximum MMSE score is 30.
Lower MMSE scores indicate more severe cognitive impairment.
|
baseline and 6 weeks
|
Neuropsychiatric Inventory (NPI): Apathy Subscale
Time Frame: baseline to week 6
|
Change from baseline to 6 weeks in neuropsychiatric symptoms in apathy subscore.
Frequency (ranges from 1=occasionally, less than once/week to 4 = very frequently, once or more/day or continuously) and severity (1=mild, 2=moderate, 3=severe) scales are scored based on responses from an informed caregiver involved in the patient's life.
To obtain the NPI score, the severity score is multiplied by the frequency score.
Range is 0 to 12. Larger numbers indicate more severe behavioral disturbance.
