Mild Cognitive Impairment Clinical Trial

Official title: Repurposing Nucleoside Reverse Transcriptase Inhibitors for Treatment of AD

Status Recruiting

Clinical Trial Summary

This is a randomized, double-blind clinical trial of a daily oral dose of 200 mg emtricitabine vs. placebo in 35 participants with biomarker-confirmed MCI or mild to moderate dementia due to Alzheimer's disease. Study duration for each subject participating in the placebo-controlled research study will be approximately 12 months (up to a 3 months Screening Period, Baseline visit (1 month), 6 months of placebo or emtricitabine dosing, and 1 month follow-up). Participants will have up to 2 months to complete all procedures for the month 6 study visit.

Clinical Trial Description

Alzheimer's disease (AD) is a devastating and increasingly frequent neurological disorder whose onset is strongly correlated with advanced age. Between 2000 and 2017 deaths from AD have increased 145%, and AD has become the 6th leading cause of death in the USA. Unfortunately, in spite of immense research and clinical efforts spanning several decades, cures have been elusive. This has prompted searches for new mechanisms of disease and new targets of therapy. One such direction is inflammation: aging and many age-associated diseases are believed to be causally linked with a chronic inflammatory state. The brain is no exception, and the presence of inflammation in the AD brain establishes an environment that is hostile for the function and survival of neurons. While it is not yet clear whether inflammation is the root cause of AD, it is increasingly believed that alleviating these inflammatory processes might slow down the progression of the disease. This research study will test to determine if the inflammatory state can be alleviated with a class of drugs known as nucleoside reverse transcriptase inhibitors (NRTIs). NRTIs were developed to treat Acquired Immune Deficiency Syndrome (AIDS) caused by infection with Human Immunodeficiency Virus (HIV). Investigators hypothesize that NRTI drugs, by inhibiting neuroinflammation, may be effective in the treatment of AD. The primary goal of this trial will be to assess safety and tolerability of Emtriva in a geriatric population of individuals diagnosed with mild cognitive impairment or early AD. This study will be conducted in subjects with mild to moderate Alzheimer's disease (AD), including subjects with mild cognitive impairment (MCI). Subjects must be positive for amyloid pathology. Subjects must be 50 to 85 years old, and apart from the clinical diagnosis of early AD, in good health as determined by the Investigator based on their medical history. Participants must be HIV/HBV negative and pass all the screening assessments based on the inclusion/exclusion criteria. ;
