Recently, the roles of inflammation and insulin resistance in neurodegeneration have become better appreciated. NE3107, an oral small molecule, blood-brain permeable anti-inflammatory insulin sensitizer that binds extracellular signal-regulated kinase, has been shown to selectively inhibit inflammation-driven ERK- and NF-κB-stimulated inflammatory mediators, including TNF-α, without inhibiting their homeostatic functions. We describe the rationale and design of NM101, the first randomized, multicenter Phase III clinical study to examine the safety and efficacy of 30 week treatment with NE3107 versus placebo in elderly adults with mild-to-moderate Alzheimer's disease. Patients (316) will be randomized in a 1:1 ratio. The co-primary end points measure cognitive function (ADAS Cog12), and functional and behavioral characteristics (ADCS CGIC). Trial registration number: NCT04669028 (Clinicaltrials.gov).

Lay abstract Diabetes and other inflammatory diseases increase the risk of Alzheimer’s disease. Insulin controls energy use in both the body and the brain. NE3107 is an oral pharmaceutical that has been shown to decrease inflammation and to improve insulin function in animals and in human subjects. We have designed a Phase III clinical trial to test the safety and activity of NE3107 in 316 elderly adults with Alzheimer’s disease, compared with a placebo capsule. After 30 weeks, assessments will be made to look for benefits in cognition, function and behavior compared with the control group.
