Detailed Description

The purpose of this research study is to investigate if suvorexant can help treat the severity of insomnia (a chronic sleep disorder) in midlife women who are pre-diabetic, and to learn whether improvement in insomnia symptoms is linked with improvement in blood sugar levels. This is a double-blind, randomized placebo-controlled crossover trial. Study procedures are conducted over a 14-week period (2-week screening period, 4-week treatment period [Block 1], 4-week washout, and 4-week treatment period [Block 2]). During each treatment block, participants take a daily pill - during one block, they take suvorexant and during the other block, they take a placebo (randomized to the order). Primary data collection includes blood draws, monitoring glucose and lipid levels, actigraphy, questionnaires, and daily diaries.
