Clinical Trial Summary

The purpose of this study is to change the concentration of amyloid-beta in human cerebrospinal fluid (CSF) by modification of sleep efficiency.

Description:

The purpose of the study is to investigate whether or not increasing sleep efficiency will change the concentration of amyloid-beta in cerebrospinal fluid (CSF).

• Neurologic or psychiatric disorder requiring medication (PI discretion)
• Alcohol or tobacco use (PI discretion)
• Use of sedating medications
• Inability to get out of bed independently
• Abnormal movement of the non-dominant arm (would affect actigraphy data in unpredictable ways)
• Abnormal physical examination

• History of migraine headaches (PI discretion)
• History of drug abuse in the past 6 months
• Urinary or fecal incontinence
• Difficulty sleeping in an unfamiliar environment (good sleep quality group only)
• History or presence of any clinically significant medication condition, behavioral or psychiatric condition (including suicidal ideation), or surgical history based on medical record or patient report that could affect the safety of the subject or interfere with study assessments or in the judgment of the PI is not a good candidate

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Difference in Amyloid-beta (Abeta) Concentration in the CSF (Cerebral Spinal Fluid) of Individuals With Poor Sleep Efficiency Compared to Those With Good Sleep Efficiency as Measured by ng/ml	Mean difference in amyloid-beta-42 concentration between individuals with poor sleep efficiency (Poor sleep group control) compared to those with good sleep efficiency (Good sleep group)	36 hours of CSF collection
Primary	Difference in Amyloid-beta (Abeta) Concentration in the CSF (Cerebral Spinal Fluid) of Individuals With Poor Sleep Efficiency Treated With Placebo, Suvorexant 10 mg, or Suvorexant 20 mg as Measured by ng/ml	Mean difference in amyloid-beta-42 concentration between individuals with poor sleep efficiency who were treated with placebo (Poor sleep group control), Suvorexant 10 mg (Poor sleep group treatment 1), and Suvorexant 20 mg (Poor sleep group treatment 2)	36 hours of CSF collection
