About this study

Official title: An Extension Open-Label Safety Study of a 24-month 20 mg Dose Regimen of Tasimelteon for the Treatment of Non-24-Hour Sleep-Wake Disorder (N24HSWD) in Blind Individuals With no Light Perception Who Have Enrolled in Other Tasimelteon Clinical Trials

The purpose of this study is to evaluate the safety of tasimelteon in male and female patients who suffer from Non-24-Hour Sleep-Wake Disorder.

Read the detailed description

Non-24-Hour Sleep-Wake Disorder (N24HSWD) occurs when individuals are unable to synchronize their endogenous circadian pacemaker to the 24-hour light-dark cycle, and the timing of their circadian rhythm instead reflects the intrinsic period of their endogenous circadian pacemaker. As a result, the circadian rhythm of sleep-wake propensity in these individuals moves gradually later and later each day if there circadian period is > 24 hours and earlier and earlier is < 24 hours. These individuals will be able to sleep well at night when their sleep-wake propensity rhythm is approximately aligned with the 24-hour light-dark and social cycle. However, after a short time, the endogenous sleep-wake propensity rhythm and the 24-hour light-dark cycle will move out of synchrony with each other, and they may have difficulty falling asleep until well into the night. In addition to problems sleeping at the desired time, the subjects experience daytime sleepiness and daytime napping. As time progresses, the endogenous circadian rhythm of sleep-wake propensity in these individuals moves further and further away from the 24-hour light-dark cycle and gradually, these individuals are unable to sleep at night and as a result experience extreme sleepiness during the daytime hours and more frequent naps with a longer duration. Eventually, the sleep-wake time moves back into alignment with the social time for sleep and the individuals sleep well at night and have decreased daytime napping. The alignment between their endogenous circadian rhythms and the 24-hour day is temporary as they are continually drifting later and later each day.

The study is comprised of one 24-month treatment phase, as all subjects enrolled in the trial have already been diagnosed with N24HSWD. Frequency of study visits will depend on the subject's prior length of exposure to tasimelteon; accordingly, subjects will be assigned to one of two groups upon enrollment into the study. The short-term exposure group will consist of subjects for which it is possible at screening that they have been exposed to tasimelteon for less than 6 months. The long-term exposure group will consist of subjects who have more than 6 months of exposure to tasimelteon.

After completion of the 24-month treatment phase, subjects have the option to enroll into the optional open-label extension sub-study for an additional 52 weeks. Frequency of visits will be identical regardless of previous exposure (short term/long term).

    Treatment-emergent adverse events will be summarized by presenting the number and percentage of patients having any treatment-emergent AE, having an AE in each body system, and having each individual AE.

    Measured: 24 months + 12 month optional extension

Secondary outcomes (4)
  1. Number of participants with changes in Clinical Laboratory Data

    Standard Serum Hematology and Chemistry tests will be performed at baseline and through the 24 months of treatment

    Measured: 24 months + 12 month optional extension

  2. Number of participants with newly occurring or worsening ECG abnormalities

    Measured: 24 months + 12 month optional extension

  3. Number of participants with clinically notable Vital Signs and Body Measurements

    Measured: 24 months + 12 month optional extension

  4. Number of participants who report a positive result for the Columbia Suicide Severity Rating Scale (C-SSRS)

    Measured: 24 months + 12 month optional extension

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing tasimelteon in people with Non-24-Hour Sleep-Wake Disorder, run by Vanda Pharmaceuticals at 22 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 15 inclusion and 12 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 21 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 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. 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?

Number of participants with Treatment-Emergent Adverse Events (AEs) (time frame: 24 months + 12 month optional extension). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 21 Apr 2015.
