INflammation-based Stratification for Immune-Targeted Augmentation in Major Depressive Disorder (INSTA-MD)

October 9, 2024 updated by: Manuel Morrens, Universiteit Antwerpen

INflammation-based Stratification for Immune-Targeted Augmentation in Major Depressive

This is a randomised, double-blind, placebo-controlled clinical trial in which patients with major depressive disorder will receive augmentation through minocycline (MCO), celecoxib (CXB) or placebo.

Study Overview

Detailed Description

This project aims to repurpose two established anti-inflammatory compounds as adjuvant therapy for immune-mediated depression, in line with state-of-the-art research of the last 10 years. Immune-mediated depression represents a subtype which accounts for approximately 30% of depressive disorders. Patients with this immunosubtype are more likely to have a higher severity of depression, a lower quality of life and more somatic symptoms. Furthermore it is accompanied by a high incidence of treatment resistance. While their mechanisms of action completely differ from those of existing antidepressant treatment options, immunomodulatory drugs celecoxib and minocycline have proven their merit as add-on treatment in depressive episodes. They have been on the Belgian market for years and come with a known pharmacological and safety profile. Patient stratification at baseline based on inflammatory status will reveal which inflammatory subpopulation benefits most from each of the two investigated anti-inflammatory compounds. Additionally, our distinctive study design allows head-to-head comparison of both add-on therapies and will as such provide the last stepping stones towards clinical implementation of individualised treatment strategies in depression.

  • Use of immunosuppressant or immunostimulant drugs within 21 days of screening (e.g., glucocorticoid treatment, methotrexate, etc.).
  • History of peptic ulcer disease or gastrointestinal (GI) bleeding.
  • Having an acute infection or inflammatory bowel disorder.
  • Current severe cardiovascular disease, congestive heart failure (NYHA-class II-IV), ischemic or thrombotic events or unstable coronary artery (incl. coronary artery bypass graft (CABG) surgery),
  • Liver impairment (alanine aminotransferase > 2x upper limit, serum albumin < 25 g/l or Child-Pugh Score ≥ 10)
  • Renal impairment (creatinine clearance < 30 mL/min).
  • Having received >14 days of tetracycline or non-steroidal anti-inflammatory medication within the previous 2 months, or having a history of sensitivity or intolerance to these classes of drugs.
  • Chronic severe hypertension (systolic BP > 170 mmHg).
  • Serology positive for hepatitis-B surface antigen, hepatitis-C antibodies or HIV antibodies.
  • Received electroconvulsive therapy < 2 months prior to screening.
  • Blood donation in 30 days prior to screening.
  • Pregnancy or breastfeeding.
  • Currently enrolled in an intervention study.
