International Study to Predict Optimised Treatment - in Depression
- Conditions
- Major Depressive Disorder
- Interventions
- Registration Number
- NCT00693849
- Lead Sponsor
- BRC Operations Pty. Ltd.
- Brief Summary
The aim of this study is to identify genetic, physical (brain) and psychological (cognitive) markers (or combinations of them) that predict specific response to a range of antidepressants treatment (Escitalopram, Venlafaxine, Sertraline) in patients diagnosed with major depressive disorder. This study is focused on outcomes which may impact on how "personalised medicine" is implemented in depression.
- Detailed Description
This is an open-label, randomised (effectiveness) study (ie. comparison of active treatments) to identify genetic markers, brain function, brain structure, and psychological and cognitive indicators (or a combination of markers) in MDD subjects versus healthy controls. Approximately 2,016 subjects with major depressive disorder (MDD) across multiple international sites (USA, Canada, UK, South Africa, New Zealand, The Netherlands and Australia) will be randomised to one of three approved and effective treatment arms:
Treatment A Escitalopram. Treatment B Sertraline. Treatment C Venlafaxine XR.
A group of matched healthy controls (n = 672) will also be enrolled.
Subjects will be asked to attend the testing facility on two separate occasions; for Pre-treatment (Pre-Tx) and at 8 weeks post initiation of treatment. The assessments/procedures at Pre-Tx and Week 8 include: Baseline a clinical work-up, blood collection for genetic analyses, cognitive testing and electrical brain functioning (EEG/ERP). Structural and functional data MRI data will be collected in ten percent (10%) of participants.
On Day 4 and Weeks 2, 4, 6, 12, 16, 24 and 52 Subjects will be contacted by phone and asked to complete 2 questionnaires via the internet.

- HAM-D17 score of ≥ 16.
- 18-65 years age-range
- Subjects with English or Dutch literacy and fluency.
- Written, informed consent.
- Presence of suicidal ideations and/or tendencies (as determined by a score >12 on Section C, Suicidality, of the MINI Plus), Bipolar I-III, psychosis, primary eating disorders, Post Traumatic Stress Disorder (PTSD), Obsessive Compulsive Disorder (OCD), Post-Natal Depression as well as any Axis II personality disorders as diagnosed using the MINI Plus or by a health care professional.

- Breastfeeding.
- Known contra-indication or intolerance to the use of Escitalopram, Sertraline or Venlafaxine XR as defined in the product package insert for each drug (including previous treatment failure at the highest recommended dose).
- Use of any psychological or counselling therapy or antidepressant/CNS drug which cannot be washed out prior to participation and eliminated until after Week 8 or discontinuation.
- Use of any medication which is known to be contraindicated with Escitalopram, Sertraline, or Venlafaxine XR (refer to the product package insert for each drug).
- Known medical condition, disease or neurological disorder which might, in the opinion of investigator/s, interfere with the assessments to be made in the study or put subjects at increased risk when exposed to optimal doses of the drug treatment.
- History of head injury with loss of consciousness for at least 10 minutes.
- Recent/current substance dependence (as defined in Section K of the Mini Plus as per a 6 months period and/or alcoholism) in the past six months.
- Participation in an investigational study within four months of the baseline visit in which subjects have received an experimental drug/device that could affect the primary end points of this study.
- Subjects who, in the opinion of the investigator, have a severe impediment to vision, hearing and/or hand movement, which is likely to interfere with their ability to complete the test batteries.
- Subjects who, in the opinion of the investigator, are unable and/or unlikely to comprehend and follow the study procedures and instructions.
