About this study

Official title: A Phase 2 Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Dose-Ranging Study to Evaluate the Phase-Shifting Effects of Repeated Daily Dosing of Ramelteon in Healthy Subjects

The purpose of this study is to determine the phase-advance in circadian rhythms in healthy adults subjects taking ramelteon, once daily (QD).

Read the detailed description

Circadian rhythms are the innate daily fluctuation of physiologic or behavior functions, included sleep-wake states, generally tied to the 24-hour daily dark-light cycle. Circadian Rhythm Sleep Disorders share a common chronophysiologic basis in which the major feature is a misalignment between the patient's sleep pattern and the sleep pattern that is desired or regarded as the societal norm.

Circadian Rhythm Sleep Disorders affect a sizable portion of the United States population, representing a significant underserved need. It has been estimated that 7% of all adolescents suffer from Delayed Sleep Phase Syndrome. Approximately 1% of all middle-aged people have Advanced Sleep Phase Syndrome. There are 21 million people who are shift workers and between 5% to 20% of these workers develop severe symptoms of Shift Work Sleep Disorder soon after starting shift work. Time Zone Change (Jet Lag) Syndrome can affect millions of travelers each year. Most symptoms are a result of sleep deprivation.

Current treatment of these disorders include behavioral therapy, light therapy and use of hypnotics and stimulants. Melatonin has also been used with mixed results.

The effects of melatonin on circadian phase depend on the time at which it is administered, and are generally opposite those of light. Specifically, melatonin given in the evening results in an advance of the circadian system to an earlier hour ("phase advance"). While melatonin appears to be useful in the treatment of sleep disruption in the blind, the phase shifting ability of native melatonin is much less than that of light, limiting its utility in the treatment of circadian dysfunction in sighted individuals.

Ramelteon is under global development as a sleep-promoting agent. Ramelteon demonstrates affinity and selectivity for human melatonin-1 or melatonin-2 receptors. Ramelteon also demonstrates full agonist activity relative to melatonin in cells expressing human melatonin-1 or melatonin-2 receptors.

The purpose of this study is to determine whether ramelteon given over multiple days can produce a phase advance in circadian rhythms as measured in salivary melatonin levels in dim-light conditions. Participation in this study is anticipated to be about 4 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ramelteon in people with Sleep Disorder, run by Takeda at 13 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 4 inclusion and 41 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 13 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Dim Light Melatonin Secretion Offset Time. (time frame: Days 1, 2, 3, and 4 or Final Visit.). 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 NCT00671190, 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.
