Our preliminary data indicate that miR-107 plays an important role in AD pathogenesis. Fibrates (PPAR agonists) increase miR-107 expression, and down-regulated BACE1 protein, an essential enzyme contributing to AD, in cultured H4 cells. We plan to test our hypotheses and evaluate a potential therapy for Alzheimer’s disease (AD) based on this novel microRNA (miRNA) pathway. Preclinical work in this area using animal models of AD has been thwarted by the species-specific hepatotoxicity not seen in humans. Thus, human clinical trials are necessary to test this important hypothesis on the disease modifying properties of fibrates in AD. Specifically, we propose an evaluation of the safety and efficacy of gemfibrozil administration on micro-RNA modulation of disease state in AD in a parallel-design, double-blind, placebo-controlled study. We will evaluate both safety and target engagement of miR-107 by gemfibrozil as well as alterations in relevant AD biomarkers. Gemfibrozil is a safe, orally-administered, FDA-approved drug for treatment of hyperlipidemia in aged individuals. The FDA has indicated IND exemption status for these studies. This study is designed to provide the foundation for future large-scale Phase II & III studies of fibrates in AD and AD prevention trials and represents the first attempt we are aware of designed to modulate disease progression in AD through influences on novel micro-RNA pathways. As such the proposed study represents a cutting-edge, data-driven, exploration of a novel disease relevant pathway that may hold promise for our global efforts targeting this major health priority among developing and developed nations.
