This study is an open-label, single-arm, proof-of-concept clinical trial evaluating empagliflozin as an adjunctive treatment for bipolar depression in individuals with insulin resistance. Adults with bipolar disorder type I or II who are currently experiencing a depressive episode and receiving stable pharmacological treatment will receive empagliflozin for 12 weeks.
Depressive symptom severity will be assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS). Insulin resistance will be evaluated using the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), and safety will be monitored through assessment of treatment-emergent adverse events throughout the study period.
