Gemfibrozil is an old member of the fibrate class of drugs. Fibrates activate peroxisome proliferator-activated receptor-α (PPARα), nuclear receptors involved in lipid metabolism. Thereby fibrates reduce triglycerides levels; they are widely prescribed to control cholesterol and for related indications.

More recently, gemfibrozil in particular has been considered to increase expression of microRNA 107 (see NIH GrantOme). Expression of miR107 has been reported to be reduced in Alzheimer's disease and implicated in regulating BACE levels (see Feb 2008 newsNelson and Wang, 2010Hebert et al., 2013). MiR107 has also been reported to be expressed in cerebrovascular endothelial cells, and proposed as a biomarker for mild cognitive impairment or Alzheimer's disease (Wang et al., 2014Wang et al., 2015Liu et al., 2016Wang et al., 2016). Panels for measuring CSF microRNA in neurodegeneration research are being developed (Wang et al., 2016).

In May 2014, an NIA-funded trial at the University of Kentucky started to evaluate whether gemfibrozil can safely modulate microRNA-107 levels for the prevention or early stage treatment of AD. The study enrolls 48 cognitively normal and 24 mildly impaired (CDR 0.5) participants for a one-year, twice-daily course of 600 mg gemfibrozil or placebo. As primary outcomes, the trial assesses adverse events, blood and CSF gemfibrozil levels, and CSF Aβ40 and 42 levels. Secondary outcomes include two cognitive tests known to be sensitive at early stages, the Free and Cued Selective Reminding Test (FCSRT) and the Paired Associates Learning (PAL) tests. The trial is set to run until summer 2016.
