Official title

A Proof-of-Concept Clinical Research Study of Efavirenz in Patients With Alzheimer's Disease

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This will be a two-center, placebo controlled blinded clinical trial to evaluate the safety and tolerability of efavirenz (EFV) in 36 clinically stable subjects with mild cognitive impairment/early dementia due to Alzheimer's Disease (AD) age ≥55 years. Of these 36 total subjects, 18 will be recruited by MGH and 18 will be recruited by UH. A subset of the subjects at MGH only will also participate in a Stable Isotope Labeling Kinetics (SILK) protocol with deuterated water (a nonhazardous substance), designed to more precisely measure EFV effects on CNS cholesterol turnover. Each respective site's 18 total recruited individuals will be divided into 3 groups: these 3 groups will represent two particular dosages of EFV and a placebo group, respectively. In a double-blind fashion, participants will be receiving either a capsule of EFV or placebo daily for 20 weeks. At MGH only, 12 individuals (4 from each of the two EFV groups and placebo) will participate in the unique "heavy water" SILK protocol assessing the kinetics of deuterium enrichment in plasma 24-hydroxycholesterol (24-OHC). All study participants at both sites will have their blood, cerebral spinal fluid, and urine analyzed at various points throughout the study. All participants will have their DNA genotyped for APOE isoforms (E2, E3 or E4) and single nucleotide polymorphisms (SNPs) in CYP46A1 (rs754203) and CYP2B6 (rs3745274) to be used for post-hoc analysis.
