About this study
Official title: A Randomized, Double-blind, Placebo-controlled, Parallel Group Study to Evaluate the Ability of Ramelteon 1 mg, 4 mg, and 8 mg to Alleviate the Insomnia Symptoms Associated With Eastward Bound Jet Lag Across 5 Time Zones in Healthy Adult Volunteers
The purpose of this study to determine the degree to which ramelteon, once daily (QD), can reduce the insomnia symptoms associated with rapid, eastward travel across 5 time zones.
Read the detailed description
Circadian dysrhythmia, or jet lag, is defined as multiple biologic and psychologic stresses created by rapid travel across multiple time zones. As more people are transported by jet aircraft, the issue of jet lag becomes more important. What was an inconvenience during travel for leisure is now a physiologic consequence for the travelers and crew.
Jet lag is composed of a variety of unpleasant symptoms that vary with the number of time zones crossed, the individual, and even the direction flown (east versus west). The most typical symptoms include daytime sleepiness, fatigue, impaired alertness, and trouble initiating and maintaining sleep. Other symptoms of circadian dysrhythmia are insomnia, gastrointestinal complaints, apathy, weakness, irritability, malaise, and loss of appetite. Travel across time zones also has been associated with diabetic ketoacidosis, depression, and impaired cognitive performance in individuals at risk. Decreased sport performance has been noted in several studies.
In addition to environmental and social cues, physical factors, such as age, hydration status, and illness, could adversely affect the ability to entrain (adjust) quickly. The stressors of flight, noise, vibration, decreased humidity, barometric pressure changes, and decreased partial pressure of oxygen all contribute to crew and travelers health at the destination.
Being out of synchronicity with the environment causes jet lag symptoms. Travel through time zones places the body in a situation when it must sleep when not tired and awaken when the internal cues are initiating sleep. The brain's internal clock is the suprachiasmatic nucleus within the hypothalamus the body is in a constant state of circadian adjustment to remain entrained to a given time zone. In addition to the subjective feeling of well being are measurable changes associated with daily patterns. For example, core body temperature changes throughout the day and decreases before falling asleep. Melatonin levels increase in the evening and night and recede during the day.
Ramelteon is a melatonin receptor 1 and melatonin receptor 2 agonist currently marketed in the US for the treatment of insomnia characterized by difficulty with sleep onset. Study participation is anticipated to be about 2 weeks.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Ramelteon in people with Circadian Dysregulation, run by Takeda at 4 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 12 inclusion and 43 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Average Latency to Persistent Sleep measured by polysomnography. (time frame: Nights 2, 3, and 4). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00492011, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Feb 2012; AzTrials last refreshed its copy on 7 Nov 2026.
