Trial summary

People who have insomnia typically co-occur with mental disorders, especially anxiety and depression. It has been documented that the melatonin phase in the depressed patients was reached with a delay. Melatonin plays a crucial role in regulation of circadian-clock-related gene expression.

About this study

Official title: Effects of a Melatonin Receptor Agonist on Clinical Manifestations and Peripheral Biological Markers of Circadian Rhythm

People who have insomnia typically co-occur with mental disorders, especially anxiety and depression. It has been documented that the melatonin phase in the depressed patients was reached with a delay. Melatonin plays a crucial role in regulation of circadian-clock-related gene expression.

Read the detailed description

The higher values of circadian-clock-related proteins observed at day (brain and muscle aryl hydrocarbon receptor nuclear translocator-like protein 1 and circadian locomoter output cycles protein kaput1) and night (period circadian protein homolog 1 and cryptochrome). Melatonin receptor type 1 (MT1) and melatonin receptor type 2 (MT2) are present in mammals including humans and involved in sleep-wake cycle. RamelteonRMT (RMT, Rozerem®), a novel MT1 and MT2 agonist, has been approved for treatment of insomnia, and provides a strong phase shift signal to the circadian timing system. Melatonin receptor agonists have recently become available for treatment of sleep and psychiatric disorders; however, the effects of the melatonin receptor agonist on peripheral biological markers of circadian rhythm are still to elucidate. This is a non-randomized, observational study, which aims of this study is to evaluate the effects of ramelteon RMT in melatonin level and the regulation of circadian rhythm genes expression in patients with primary insomnia, and/or major depressive disorder (MDD) on, or generalized anxiety disorder (GAD) with symptoms of insomnia. Forty Participants: Participants aged 20-80 years with body mass index between 18 and 34 and without any ambulatory problems will be recruited according to clinical judgment to take RMT for insomnia, ages 20-80 years, body mass index between 18 and 34, without any ambulatory problems, and be willing to write sleep diary. Primary insomnia, MDD and GAD will be as defined by the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition Revised for at least 3 months and a history of daytime complaint(s) associated with disturbed sleep. Participants were administered the ramelteon RMT tablet (8 mg/Tab) by oral intake at the same time, which is 2 hours prior to the schedule bedtime every night for eight weeks. The peripheral blood is collected at two time points - ramelteon RMT administration week 0 and week 8, and the melatonin, circadian-clock-related day genes (Aryl hydrocarbon receptor nuclear translocator-like protein 1 and Circadian locomoter output cycles protein kaput1) and night genes (circadian protein homolog 1 and cryptochrome) expression variation will be quantified and compared to determine circadian rhythm phase shift. The expected findings are the circadian-clock-related genes would shift to normal baseline and these genes expressions will be the peripheral marker for evaluation of drug treatment efficacy.

Questions about this trial

What is this clinical trial studying?

An observational study of Insomnia, run by National Science and Technology Council, Taiwan.

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 6 inclusion and 9 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 10 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

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.

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?

The Change from Baseline Hamilton depression rating scale at 8 weeks (time frame: 8 weeks). 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 10 Oct 2022.
