Trial studying safety and effects for Psychiatric Disorders
Official title Efficacy of Melatonin, Low-dose Quetiapine, or Placebo in Patients With Psychiatric Disorders and Comorbid Insomnia
ClinicalTrials.gov ID: NCT06062953
What this study is testing
What is Melatonin?
An investigational oral supplement being studied as a potential treatment for insomnia in patients with psychiatric disorders. Melatonin is designed to help regulate the body's sleep‑wake cycle by activating melatonin receptors in the brain.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study wants to see if melatonin or low‑dose quetiapine improves sleep better than placebo, and how they affect overall symptoms, sleep quality, daily functioning, and well‑being.
- Who it's for
- Adults who have a psychiatric disorder and also have trouble sleeping (insomnia).
- What's involved
- You will be randomly given melatonin, low‑dose quetiapine, or a placebo pill for six weeks, then taper off the medication. The study includes clinic visits for assessments and safety checks.
- Time commitment
- The trial lasts about six weeks of treatment plus a short taper, with regular study visits during that time.
- Phase 3: a large, late-stage study
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
