About This Trial

This study used polysomnographic technology and randomly selected 60 patients who met the diagnostic criteria for depression and non-organic insomnia as stipulated in DSM-5 into an intervention group (n=30) and a control group (n=30). The intervention group was given only 5-hydroxytryptamine balanced antidepressants trazodone, while the control group was given citalopram hydrobromide combined with zolpidem. Both groups underwent PSG at baseline and 1 week after medication, and were assessed with the 17-item Hamilton Depression Rating Scale, Zung Self-Rating Depression Scale, Pittsburgh Sleep Quality Index, Arnsworth Insomnia Severity Scale, Antidepressant Side Effects Checklist, and the Drug Dependence Scale neuropsychological assessment at baseline, 1, 2, and 4 weeks after medication. The study aimed to explore the effects of single use of SMAs class antidepressants versus combination with other antidepressants on non-rapid eye movement sleep stage III in patients with depression and insomnia comorbidity, and to compare the effects of depression and insomnia in the two groups.

What Stage of Research Is This?

Phase 4 studies happen after a treatment has been approved by the FDA. They monitor long-term safety, real-world effectiveness, and any rare side effects that only emerge in larger populations over longer periods. Phase 4 results sometimes lead to label changes, additional warnings, or — rarely — withdrawal of approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 60 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Depressed Insomniac Co-morbid Patients subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.
