About this study

Official title: Allelic Linkage in Substance Abuse

This investigation seeks to better define the genetic basis for vulnerability to substance abuse.

Read the detailed description

Dopamine (DA), a neurotransmitter helping to mediate reward and reinforcement, has been putatively linked to the development of substance abuse, alcohol abuse, and alcoholism. Identification of specific vulnerability-association alleles for receptors, other molecules within the reward mediating system, and other genes that may predispose individuals to the development of such disorders is the goal of the study.

This investigation will help elucidate the genetic underpinnings of substance abuse, potentially leading to the improved methods to diagnose those at risk and to help develop better therapeutic interventions.

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 NCT00247819, which also lists 17 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.
