Brief Summary in Lay Language

Major depressive disorder (MDD) and obesity are major contributors to impaired health worldwide. Statins are among the most prescribed medications with well-established safety and efficacy. Statins are recommended in primary prevention of cardiovascular disease, which has been linked to both MDD and obesity. Moreover, statins are promising candidates to treat MDD because a meta-analysis of pilot randomized controlled trials has found antidepressive effects of statins as adjunct therapy to antidepressants. However, no study so far has tested the antidepressive potential of statins in patients with MDD and comorbid obesity. Therefore, we hypothesize that Simvastatin add-on to standard antidepressant Escitalopram will improve depression to a greater extent than add-on placebo in patients with comorbid obesity and major depression. We will randomize 160 obese MDD patients at 8 recruiting centers to either Simvastatin or placebo as add-on to Escitalopram for 12 weeks. If successful, our trial would have immediate impact on clinical practice given the fact that Simvastatin and Escitalopram are available as inexpensive generic drugs with established safety.

Brief Summary in Scientific Language

Simvastatin is approved for several indications since decades and has in general proven to be an effective and safe medication in primary prevention of cardiovascular disease, which has been linked to both MDD and obesity. Preclinical and clinical data suggest that adjunctive treatment with statins could be useful for the treatment of depressive symptoms. Therefore, in our study, we want to investigate whether add-on Simvastatin to standard antidepressant medication improves depression to a greater extent than adjunct placebo in patients with major depression and comorbid obesity.

Primary Outcome

- Change score in MADRS (Montgomery-Asberg-Depression Rating Scale); time frame: 12 weeks; The MADRS is a rating scale to measure depression severity. Each MADRS item is rated on a 0 to 6 scale. Total score range from 0-60, where higher MADRS scores indicate higher levels of depressive symptoms.

end of 1:1-Block primary endpoint
start of 1:1-Block secondary endpoint

Secondary Outcome

- MADRS-response (50 % MADRS score reduction from baseline), MADRS-remission (MADRS score < 10), and MADRS-minimal clinically
important difference (MCID)
- change Beck Depression Inventory (BDI-II) scores from baseline to week 12, and BDI-II-MCID
- change in Patients’ Global Impression of Change Scale (PGIC), change in Clinicians’ Global Impression of Severity of illness (CGI-S), Clinicians’ Global Impression of Improvement (CGI-I), EuroQol-5 Dimensions-3 Levels Questionnaire (EQ-5D-3L), and Social and Occupational Functioning Assessment Scale (SOFAS) from baseline to week 12
