A 24-week, double blind placebo study investigating the effects of the amino acid ‘N-acetylcysteine’ (NAC) in Obsessive-Compulsive Disorder (OCD). This study will determine if NAC is an effective treatment for individuals with OCD.
This NHMRC funded study is currently enrolling participants at 3 trial sites – The University of Melbourne, University of Queensland and Western Sydney University. We aim to recruit 200 participants – the largest NAC trial for OCD to date.
Eligible participants will be randomised to receive NAC (2,000mg – 4,000mg per day) or placebo capsules alongside their treatment as usual for a period of 6 months. Monthly assessments with a research assistant at their designated trial site (approx. 60-90 mins) will determine if any improvements have occurred in OCD symptoms, as well as depression, anxiety and quality of life.
