Official title

Use of N-Acetylcysteine (NAC) in the Treatment of Repetitive Behaviors (RB) and Self-Injurious Behaviors (SIB) in Cornelia de Lange Syndrome: A Randomized Double-Blind Placebo-Controlled Pilot Study

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This research project is a randomized cross-over pilot trial which aims to test the efficacy of N-acetylcysteine (NAC) for the treatment of Repetitive Behaviors (RB) and self-injurious behavior (SIB) in patients with Cornelia de Lange Syndrome (CdLs). NAC is a known anti-oxidative stress and neuroprotective agent, which has been shown to decrease the occurrence of SIB such as skin picking. NAC has also shown partial response in trials for compulsive behaviors in Obsessive Compulsive Disorder (OCD) and related disorders in autism. Cornelia de Lange syndrome (CdLS) is a genetic disorder with autistic features, including RBs and SIB. In this randomized clinical trial, participants with CdLS will be blindly assigned one of two possible treatment arms: 1) placebo (8 weeks) and NAC (8 weeks); or 2) NAC (8 weeks) and placebo (8 weeks), with an intermediate 2-week washout period.
