What this trial studies

This is a phase 1/2 interventional trial conducted at a single center enrolling adults with major depressive disorder of at least two months' duration and a Hamilton rating score over 18. Participants receive fluoxetine and dapagliflozin with regular monitoring for changes in depressive symptoms and for safety and tolerability. The trial excludes people with bipolar disorder, active substance dependence, diabetes, severe kidney disease, recent ECT, or pregnancy/lactation. Outcomes will focus on symptom change (Hamilton rating) and adverse events to provide preliminary efficacy and safety data.

Who should consider this trial

Good fit: Adults aged 18 or older with major depressive disorder lasting at least two months and a Hamilton rating score >18 who are not pregnant, not diabetic, and without bipolar disorder, substance dependence, severe kidney disease, or contraindications to the study drugs.

Not a fit: People with bipolar I/II, active substance dependence or abuse, diabetes, severe renal impairment, pregnancy or lactation, or primary personality or eating disorders are unlikely to be eligible or to benefit from this protocol.

Why it matters

Potential benefit: If successful, adding dapagliflozin could improve depressive symptoms and offer a new treatment option for patients who do not fully respond to standard antidepressants.

How similar studies have performed: Repurposing SGLT2 inhibitors like dapagliflozin for depression is largely novel with limited clinical data, though some preclinical and mechanistic studies suggest possible neuroprotective or anti-inflammatory effects.
