ClinConnect Summary

This clinical trial is studying a new medication called YZJ-1139, which is designed to help adults with insomnia disorder, a condition that makes it hard to fall or stay asleep. The trial will last for 28 days and will evaluate how well the medication works by looking at both objective measures (like sleep studies) and subjective reports (how patients feel about their sleep). Researchers are currently looking for participants between the ages of 18 and 65 who meet specific criteria for insomnia, such as experiencing difficulty sleeping at least three nights a week.

Eligible participants will need to have a consistent sleep schedule and be in generally good health, without serious medical or psychiatric conditions that could interfere with the study. Those who join the trial can expect to attend regular visits, complete sleep diaries, and undergo sleep monitoring. It's important for participants to understand the study procedures and provide consent to participate. This trial aims to provide valuable information on the safety and effectiveness of YZJ-1139 for treating insomnia, potentially helping many people struggling with sleep issues.
