- Lead Sponsor
- Takeda
- Brief Summary
The purpose of this study is to determine the subjective treatment effects of ramelteon, once daily (QD), on sleep using a post sleep questionnaire-interactive voice response system in adults with chronic insomnia.
- Detailed Description
Approximately 60 to 70 million adults in the United States alone are affected by insomnia. Daytime symptoms of insomnia include tiredness, lack of energy, difficulty concentrating, and irritability. Recent epidemiologic research focusing on the quality of life has identified significant insomnia-related conditions that relate to work productivity, health care utilization, and risk of depression. Insomnia is associated with diminished work output, absenteeism, and greater rates of accidents.
Ramelteon is marketed for the treatment of insomnia characterized by difficulty with sleep onset under the brand name of Rozerem™.
This study will be comprised of two groups of subjects, 1) an outpatient group and 2) an inpatient group. The inpatient group will be used as reference arm as previously conducted studies in the sleep laboratory setting. Study participation is anticipated to be about 50 days (approximately 1.75 months).
