What this trial studies

This study evaluates the effectiveness of Sumor, a food supplement containing key coenzymes and vitamins, as an adjuvant therapy for patients with treatment-resistant Major Depressive Disorder. Participants will receive either Sumor in combination with an SSRI antidepressant or a placebo alongside their SSRI treatment. The study aims to determine if this combination can improve depressive symptoms compared to a placebo. The trial is designed for adults aged 18 to 65 who have not responded adequately to standard SSRI therapy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 diagnosed with Major Depressive Disorder who have not responded to SSRI treatment.

Not a fit: Patients with bipolar disorder, schizophrenia, or those currently taking other antidepressants or mood stabilizers may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new therapeutic option for patients suffering from treatment-resistant depression.

How similar studies have performed: There are currently no published studies on the efficacy of this specific combination of ingredients for treating depression, making this approach novel.
