Summary

Bipolar disorder is a long-term mental health condition that causes mood changes, with depressive episodes being the most frequent and disabling. Many people do not fully recover with current treatments, showing the need for new therapeutic options.

Recent research shows that insulin resistance (IR), a condition in which the body does not respond well to insulin, is common in people with bipolar disorder. It is linked to more severe mood symptoms, poorer treatment response, and higher risk of heart disease. IR may raise inflammation and affect how the brain uses energy, which can influence mood regulation.

Empagliflozin is a medicine approved for type 2 diabetes. In addition to its metabolic and heart benefits, studies suggest that it may also protect the brain and reduce inflammation, possibly helping to improve mood.

This open-label, proof-of-concept clinical trial will test how well empagliflozin works and how safe it is as an add-on treatment for people with bipolar depression and insulin resistance. A total of 20 adults with bipolar disorder type I or II, currently in a depressive episode, will take part in the study over a 12-week period.

The main goal is to see whether empagliflozin can lower depressive symptoms, measured with the Montgomery-Åsberg Depression Rating Scale (MADRS). Other measures include changes in insulin resistance and incidence of adverse events.

The study aims to explore whether improving insulin resistance can help both mood and metabolic health in people with bipolar disorder, guiding future clinical research.

Interventions

DRUG

Empagliflozin (EMPA)

Empagliflozin is a sodium-glucose cotransporter 2 (SGLT2) inhibitor administered orally once daily. Participants will start with 10 mg/day for the first 2 weeks, followed by 25 mg/day for the next 10 weeks, completing a 12-week intervention period. The drug will be used as an adjunctive treatment to standard psychiatric therapy in adults with bipolar depression and insulin resistance. Safety and tolerability will be monitored throughout the study.
