Antigonadotropin-Leuprolide in Alzheimer's Disease Drug INvestigation (ALADDIN) VP 104 Study
Summary
ALADDIN is a research study to investigate the safety and effectiveness of leuprolide (a hormone drug) to improve the cognitive function and slow the progression of Alzheimer's disease (AD) in men 65 years and older with mild to moderate Alzheimer's disease who reside in the community.
Description
ALADDIN is a clinical trial investigating the safety and effectiveness of leuprolide (a hormone drug) to improve the cognitive function and slow the progression of Alzheimer's disease (AD). The study will include treatment of men 65 years and older with mild to moderate Alzheimer's disease who reside in the community. The objective is to evaluate the safety and efficacy of two different doses of leuprolide to improve the cognitive function and slow the progression of AD, as measured by the ADAS-COG and the Clinical Global Impression (CGI). Measures of behavioral disturbances, and quality of life of the caregiver will be made also. The study design is randomized, double blind, placebo-controlled, parallel group design with a 2:1 randomization of drug to placebo. Sample size will include 90 participants from multiple test sites.
Following initial screening and baseline visits, the participant and caregiver will visit the site 8 times for a total of 10 visits over 48 weeks. The drug is administered via injection every 3 months. Safety assessments are completed and psychometric testing is done. Participant's memory, behavior, and global functioning are assessed during the participant and caregiver interviews. Each visit takes approximately 2 hours.

Medical and Biotech [MESH] Definitions
Neuropil Threads
Abnormal structures located chiefly in distal dendrites and, along with NEUROFIBRILLARY TANGLES and SENILE PLAQUES, constitute the three morphological hallmarks of ALZHEIMER DISEASE. Neuropil threads are made up of straight and paired helical filaments which consist of abnormally phosphorylated microtubule-associated tau proteins. It has been suggested that the threads have a major role in the cognitive impairment seen in Alzheimer disease.
Alzheimer Vaccines
Vaccines or candidate vaccines used to prevent or treat ALZHEIMER DISEASE.
Aphasia, Primary Progressive
A progressive form of dementia characterized by the global loss of language abilities and initial preservation of other cognitive functions. Fluent and nonfluent subtypes have been described. Eventually a pattern of global cognitive dysfunction, similar to ALZHEIMER DISEASE, emerges. Pathologically, there are no Alzheimer or PICK DISEASE like changes, however, spongiform changes of cortical layers II and III are present in the TEMPORAL LOBE and FRONTAL LOBE. (From Brain 1998 Jan;121(Pt 1):115-26)
Acetylesterase
An enzyme that catalyzes the conversion of acetate esters and water to alcohols and acetate. EC 3.1.1.6.
Amyloid Beta-protein Precursor
A precursor to the AMYLOID BETA-PROTEIN (beta/A4). Alterations in the expression of the amyloid beta-protein precursor (ABPP) gene, located on chromosome 21, plays a role in the development of the neuropathology common to both ALZHEIMER DISEASE and DOWN SYNDROME. ABPP is associated with the extensive extracellular matrix secreted by neuronal cells. Upon cleavage, this precursor produces three proteins of varying amino acid lengths: 695, 751, and 770. The beta/A4 (695 amino acids) or beta-amyloid protein is the principal component of the extracellular amyloid in senile plaques found in ALZHEIMER DISEASE; DOWN SYNDROME and, to a limited extent, in normal aging.
