About this study

Official title: A Phase III, Randomized, Double-Blind, Placebo-Controlled, Outpatient, Safety and Efficacy Study of TAK-375 in Adults With Chronic Insomnia

The purpose of this study is to determine the safety and efficacy of Ramelteon, once daily (QD), in adult subjects with chronic insomnia.

Read the detailed description

Insomnia is characterized by difficulties initiating and maintaining sleep or complaints of nonrestorative and non-refreshing sleep. Transient insomnia affects approximately one-third to one-half of the US population, based on the results of 2 surveys of representative samples of the adult US population conducted by the Gallup Organization in which respondents were asked if they had "ever had difficulty sleeping." Based on reports of "regular" or "frequent" sleep difficulty, results from the same studies suggest that approximately one-tenth of the US population experiences chronic insomnia. The ideal treatment for insomnia would reduce the latency to onset of sleep and increase total sleep time, without a negative impact on sleep architecture and without safety concerns or next-day effects.

Ramelteon is a melatonin-1 receptor agonist under global development by Takeda Chemical Industries, Ltd, for the treatment of transient and chronic insomnia and for the treatment of Circadian Rhythm Sleep Disorders.

This study is designed to determine the safety and efficacy of 35-day treatment of chronic insomnia with Ramelteon, using subjective measures of sleep. Total subject participation time in this study is expected to be approximately 2 months.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ramelteon in people with Chronic Insomnia, run by Takeda at 70 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 5 inclusion and 35 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 20 Nov 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 70 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Mean Subjective Sleep Latency per subject diary, from Nights 1 through 7 of double-blind treatment. (time frame: Weeks 1, 2, 3, 4, and 5 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 NCT00671567.

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 20 Nov 2012.
