What this trial studies

This observational study focuses on drug-naïve outpatients diagnosed with depression or bipolar disorders who are beginning treatment with specific medications. Participants will have five blood samples collected at various intervals after starting their treatment to assess the relationship between blood biomarkers and treatment response. The primary goal is to enhance early diagnosis and optimize pharmacological treatment, ultimately guiding personalized clinical practices. This study does not influence the choice or dosage of the medication prescribed.

Who should consider this trial

Good fit: Ideal candidates are adult drug-naïve outpatients suffering from depression or bipolar disorders who are starting treatment with escitalopram, fluoxetine, sertraline, or quetiapine.

Not a fit: Patients with a history of harmful use of psychoactive substances or those lacking the capacity for discernment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate and individualized treatment plans for patients with depression and bipolar disorders.

How similar studies have performed: While this approach is innovative, similar studies exploring blood biomarkers in mental health have shown promise, indicating potential for success.
