What is the purpose of this trial?

This trial tests a medication called tasimelteon to determine if it can help children and teens with insomnia, a condition that makes falling or staying asleep difficult. The study compares tasimelteon to a placebo (an inactive pill) to assess its effectiveness and safety. Ideal candidates are children and teens aged 2 to 17 diagnosed with insomnia, where sleep issues aren't caused by other medications. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to a potentially groundbreaking treatment for insomnia.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, your sleep issues must not be caused by another medication.

Is there any evidence suggesting that tasimelteon is likely to be safe for humans?

Research has shown that tasimelteon is generally safe for use. Previous studies found that most people tolerated it well, experiencing few effects the next day. In one study, only 21.4% of participants reported mild side effects, and no serious side effects occurred. This indicates that most people did not encounter major problems while taking it. Tasimelteon is also approved for other conditions, suggesting its safety. Overall, the treatment appears safe based on the available data. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for insomnia?

Unlike other treatments for pediatric insomnia, which often rely on behavioral therapies or medications like melatonin supplements, Tasimelteon offers a novel approach. Tasimelteon is unique because it targets the body's internal clock, or circadian rhythm, by acting as a melatonin receptor agonist. This mechanism helps regulate sleep-wake cycles more naturally compared to traditional options. Researchers are excited about this treatment's potential to provide a more precise and effective way to help children with insomnia get a good night's sleep.

What evidence suggests that tasimelteon might be an effective treatment for pediatric insomnia?

Research has shown that tasimelteon, a drug similar to melatonin, can improve sleep. Studies have found that it helps people with insomnia fall asleep faster, starting from the first night and continuing throughout the treatment period. Tasimelteon is generally well-tolerated, causing no next-day problems. Although primarily approved for Non-24-Hour Sleep-Wake Disorder, these findings suggest it might also benefit children with insomnia. Participants in this trial will receive either tasimelteon or a placebo to evaluate its effectiveness for pediatric insomnia. ^{1 2 3 4 5}

What Are the Treatments Tested in This Trial?

Interventions

• Tasimelteon

Trial Overview The study is testing tasimelteon, a medication given as an oral suspension, against a placebo (a substance with no active drug). It's designed so neither the researchers nor participants know who gets the real medicine versus the placebo to fairly measure its effects on pediatric insomnia.

Published Research Related to This Trial

In two phase III trials involving totally blind individuals with Non-24-Hour Sleep-Wake Disorder, tasimelteon (20 mg once nightly) significantly improved the ability to entrain the circadian pacemaker compared to placebo.

Tasimelteon was generally well tolerated and also led to improvements in sleep/wake parameters and overall functioning, making it a valuable treatment option for Non-24 in this population.

Tasimelteon, a dual melatonin receptor agonist approved for Non-24-Hour Sleep-Wake Disorder, showed an absolute bioavailability of 38% in a study involving 14 healthy volunteers, indicating effective absorption when taken orally.

The study found that tasimelteon was well tolerated, with only mild treatment-emergent adverse events reported in 21.4% of participants, and no serious adverse events or discontinuations, highlighting its safety profile.

Tasimelteon (Hetlioz®) is the first FDA-approved treatment for non-24-hour sleep-wake disorder, particularly effective in blind individuals, as it helps reduce nighttime wakefulness and daytime sleepiness by promoting synchronization to the 24-hour cycle.

The drug is well tolerated with common side effects including headaches and unusual dreams, and ongoing safety studies are being conducted to further assess its effects in blind patients.

Melatonin significantly reduced sleep onset time (SOT) by an average of 0.62 hours and improved dim light melatonin onset (DLMO) by 0.82 hours in children and adolescents with sleep onset insomnia, based on a review of seven trials involving 387 participants.

The treatment was found to be effective and generally well-tolerated, with no significant differences in dropout rates due to adverse events, although some mild adverse effects were reported, indicating a need for further research, especially in adolescents.

Tasimelteon, a melatonin receptor agonist, is the first approved treatment for Non-24-hour Sleep-Wake Disorder, showing a strong affinity for the MT2 receptor, which helps regulate sleep cycles.

In a study involving 184 blind individuals over more than a year, tasimelteon was found to be safe and well-tolerated, with adverse effects similar to those seen in placebo groups, indicating its potential for long-term use.
