Study of Nasal Insulin to Fight Forgetfulness (SNIFF)

Start: September 2013
End: December 2018
Enrollment: 240

What Is This Study About?

This Phase II/III clinical trial will examine whether a type of insulin, when administered as a nasal spray, improves memory in adults with a mild cognitive impairment or Alzheimer’s disease. The study will also provide evidence about how intranasal insulin works in the body.
