"Pilot Study of Armodafinil in Patients With Dementia With Lewy Bodies"

Completed · Phase 4

Conditions studied: Dementia With Lewy Bodies

In brief

This research study is to examine the effects of the study medication Armodafinil in patients with dementia with Lewy bodies (DLB). DLB is associated with memory and other thinking problems, excessive daytime sleepiness, hallucinations, delusions, apathy, and reduced quality of life. One type of medication that could potentially improve daytime sleepiness, memory and thinking skills, hallucinations, delusions, apathy, and quality of life is known as a wake-promoting medication. Armodafinil is a wake-promoting medication that has been developed for treatment of patients with narcolepsy, sleep apnea, and other disorders which cause excessive daytime sleepiness. The drug used in this study is considered investigational, which means it has either not been approved by the Food and Drug Administration (FDA) for routine clinical use or for the use described in this study. However the FDA has allowed the use of this drug/device in this research study. In this study, patients with DLB will receive daily oral Armodafinil tablets, and their response to treatment will be assessed over 12 weeks. This study does not involve any placebo medication, so all patients will receive Armodafinil treatment.

• No active medical disorder that could preclude participation in a drug treatment trial over a 12 week protocol
• Stable medication regimen over previous four weeks
• Absence of psychotropic medications at doses viewed by the clinician to be significantly impacting the patient's alertness during wakefulness
• Absence of clinically significant primary sleep-related breathing disorder causing sleepiness as demonstrated by polysomnography (PSG) [ie, no significant upper airway resistance syndrome (UARS), obstructive sleep apnea (OSA), nor central sleep apnea (CSA) as reflected by a combined respiratory disturbance index (RDI) <15] OR adequate documentation of efficacy of treatment for UARS, OSA, and CSA

You may not qualify if…

• Does not fulfill criteria for clinically possible or probable DLB
• Age <50 or >90
• Women with intact uterus and not post-menopausal unless pregnancy test performed at screening is negative
• Epworth Sleepiness Scale score less than 8
• MMSE score <10 or >26
• Active medical disorder that could preclude participation in a drug treatment trial over a 52 week protocol, such as:
• Hypertension with BP readings exceeding 150 mm Hg systolic and 90 mm Hg diastolic
