Summary

The Apathy in Dementia Methylphenidate Trial (ADMET) is a masked, placebo-controlled trial that will examine the efficacy and safety of methylphenidate for the treatment of clinically significant apathy in patients with Alzheimer's dementia.

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.

Interventions

Type	Name	Description
DRUG	Methylphenidate	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.
DRUG	placebo	Patients will start with two capsules of placebo for three days, at which time the dose will be increased to four capsules. The dose may be reduced to a minimum of two capsules per day if there appears to be significant side-effects. Placebo will be administered for 6 weeks.
OTHER	Psychosocial intervention	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: * Review and adjustment of the patient and caregiver supportive care plans * Emotional support and opportunity to ventilate feelings * Counseling regarding specific caregiving skills * Assistance with problem solving of specific issues that the caregiver brings to the sessions * Answers for questions regarding the educational materials The educational materials will consist of a copy of the book The 36-Hour Day
