What this trial studies

This study evaluates the safety and effectiveness of fosigotifator (ABBV-CLS-7262) in adults diagnosed with major depressive disorder (MDD). It is a double-blind, randomized trial where participants will receive either the treatment or a placebo, with a 50% chance of receiving each. Approximately 106 adult participants will be enrolled across 15 sites globally, and the study aims to gather data on adverse events associated with the new medication. Participants must meet specific criteria related to their depression and body mass index to qualify for the study.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 with a diagnosis of major depressive disorder who meet specific inclusion criteria.

Not a fit: Patients with primary psychiatric illnesses other than major depressive disorder will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients suffering from major depressive disorder.

How similar studies have performed: Other studies have shown promise with similar approaches in treating major depressive disorder, but the specific treatment being tested is novel.
