E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate whether a 12-week celecoxib treatment (400mg/day) added to treatment as usual (TAU, defined as pharmacotherapy and/or psychotherapy) is more effective in reducing depressive symptoms as measured with the Inventory of Depressive Symptomatology (IDS 30-item self-report version) than placebo in patients aged 18-65yr with major depressive disorder and IMD characteristics (atypical, energy-related symptoms (≥6 on IDS)(Lamers et al. 2020) and circulating CRP>1mg/L) during 12-week follow-up. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate whether in patients aged 18-65yr with major depressive disorder and IMD characteristics (atypical, energy-related symptoms (≥6 on IDS) and circulating CRP>1mg/L) a 12-week adjunctive celecoxib treatment (400mg/day) vs placebo is: - more effective in reaching response (defined as 50% reduction in total IDS score) and remission (based on the Mini International Neuropsychiatric Interview [MINI]) - more effective in improving functioning (WHO-DAS), lowering fatigue (CIS), food craving (GFCQ-T), and pain (Numeric Rating Scale) - more effective in lowering atypical-energy related symptoms (IDS atypical, energy-related symptom profile score)
To better understand how and for whom celecoxib add-on treatment is effective, several biological makers are assessed: - inflammatory markers (CRP, IL-6, TNFa), cholesterol, triglycerides, glucose, BMI, waist circumference
