What this trial studies

This clinical trial is a randomized controlled trial that aims to compare the effectiveness of ketamine-assisted psychotherapy (KAP) with standard ketamine treatment without psychotherapy (KET) in adults suffering from major depressive disorder (MDD). Participants will be randomly assigned to either KAP or KET and will undergo treatment over a four-week period. The study will assess various outcomes, including depression severity and neurocognitive functioning, at baseline, immediately after treatment, and during an eight-week follow-up. The goal is to determine if the addition of psychotherapy enhances the therapeutic effects of ketamine.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients with major depressive disorder by combining psychotherapy with ketamine.

How similar studies have gone: Other studies have shown promising results with ketamine-assisted psychotherapy, indicating potential success for this approach.
