Cannabidiol Oil for Treatment-Resistant Major Depression

Major depressive disorder is one of the leading causes of disability worldwide, and a substantial proportion of patients do not achieve adequate improvement with conventional antidepressant treatments. Cannabidiol (CBD), a non-intoxicating cannabinoid derived from Cannabis sativa, has shown potential anxiolytic, anti-inflammatory, and neurobiological effects that may be relevant for depressive disorders. The ANANDA trial is a multicenter, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the efficacy, safety, and tolerability of full-spectrum cannabidiol oil as an adjunctive treatment in adults with treatment-resistant major depressive disorder. A total of 120 participants will be randomly assigned to receive either full-spectrum cannabidiol oil or placebo for 12 weeks while maintaining stable antidepressant treatment. Clinical assessments of depressive symptoms, anxiety, sleep quality, perceived stress, and adverse effects will be performed at baseline, Week 4, and Week 12. Blood samples will be collected at baseline and after 12 weeks to investigate inflammatory and neuroendocrine biomarkers. The primary objective is to evaluate changes in depressive symptoms after 12 weeks of treatment. Secondary objectives include the assessment of anxiety, sleep quality, perceived stress, biological markers, safety, and tolerability. The findings of this study may contribute to the development of new therapeutic approaches for treatment-resistant depres…
