Clinical Trial Summary

The primary purpose of this study is to determine whether empagliflozin, a medication in a class known as sodium-glucose cotransporter-2 inhibitors (SGLT2) inhibitors, may reduce symptoms of depression. Since this medication helps the body make metabolites known as ketone bodies which can serve as an alternate energy source for the brain, the investigators can also test whether ketone bodies help with depressed mood.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Score	10-item physician-rated scale assessing depressive symptomology. Each item is rated on a Likert scale ranging from 0 to 6. The total score is the sum of responses and ranges from 0 to 60; higher scores indicate greater depressive symptomology. Specifically, a total score ranging from 0 to 6 indicates that the patient is in the normal range (no depression); a score ranging from 7 to 19 indicates "mild depression;" 20 to 34 indicates "moderate depression;" a score of 35 and greater indicates "severe depression;" and a total score of 60 or greater indicates "very severe depression."	Baseline, Week 6
Secondary	Change from Baseline in Columbia Suicide Severity Rating Scale (C-SSRS) Score	C-SSRS systematically tracks suicidal ideation and behavior. The total score range is 0 (no ideation is present) - 5 (active suicidal ideation with specific plan and intent). The higher the score, the greater one's suicidal ideation. Any score greater than 0 is important and may indicate the need for mental health intervention.	Baseline, Week 6
Secondary	Change from Baseline in Snaith-Hamilton Pleasure Scale (SHAPS) Score	14- item questionnaire assessing four domains of pleasure response, aimed as a scale to measure anhedonia, or the inability to experience pleasure. Each item is rated on a Likert scale ranging from 1 (strongly disagree) to 4 (strongly agree). The total score is the sum of responses and ranges from 14 to 56; higher scores indicate lesser anhedonia.	Baseline, Week 6
