Trial summary

The purpose of this study is to identify genes that affect susceptibility to obsessive-compulsive disorder (OCD). By identifying genes that increase or decrease the risk of OCD, researchers can better understand how the condition develops and ultimately improve treatment for people with OCD.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Must have a diagnosis of obsessive-compulsive disorder, or be a family member (usually a parent or sibling) of someone with obsessive-compulsive disorder.
  • Certain disorders are considered part of OCD "spectrum" disorders and often include family members with OCD. These include Tourette's Syndrome, other individuals with tics, and Trichotillomania (severe hair pulling), and other forms of repetitive behaviors.
  • Persons with primary behavioral difficulties who do not fit with the current definitions of "OCD and OCD spectrum disorders" may not be eligible. These include compulsive shopping, gambling, or compulsive sexual behaviors.

Who cannot join

About this study

Official title: Genetics of Obsessive-Compulsive Disorder: A Collaborative Study

The purpose of this study is to identify genes that affect susceptibility to obsessive-compulsive disorder (OCD). By identifying genes that increase or decrease the risk of OCD, researchers can better understand how the condition develops and ultimately improve treatment for people with OCD.

OCD is a severe, familial condition that affects approximately 2% of the population. The way OCD is inherited is not clearly understood, but researchers believe it is complex and involves multiple genes. This study will detect and localize genes that increase or decrease susceptibility to OCD. The data collected from this study will be combined with data from other research studies to determine gene linkage and association.

Read the detailed description

Obsessive-compulsive disorder (OCD) is a severe, heritable condition with a lifetime prevalence of about two percent of the population. The mode of inheritance is poorly understood but is likely complex, involving multiple loci of small to major effect. Since 1995, the NIMH-IRP has been active in a multi-center family study of OCD, led by Dr. Gerald Nestadt of Johns Hopkins University, which was approved via a competitive NIMH extramural application (MH 502140). An expanded consortium of sites (including new sites at Brown and Harvard Universities) anticipates adding 300 new affected sib-pair families over the next three years. This sample will be used for linkage and association analyses. Data will be shared within this consortium of investigators studying OCD, and will eventually be combined with data obtained from a second consortium.

Questions about this trial

What is this clinical trial studying?

An observational study of Obsessive Compulsive Disorder, run by National Institute of Mental Health (NIMH) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00001548, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2017.
