The CTN infrastructure consists of the National Institute on Drug Abuse (NIDA), multiple Nodes – each linked with several treatment sites representing the continuum of SUD care, a Clinical Coordinating Center, and Data and Statistical Center. This framework allows the CTN to rapidly test and disseminate science-based treatments to communities nationwide.


The Data and Statistics Center (DSC) for the CTN has developed a website to support management and monitoring of trial progress and general CTN activities. One main feature of this website is a comprehensive set of standardized Trial Progress Reports (TPRs) and Data Status Reports (DSRs) that can be used as a management tool to effectively monitor trial progress in real-time. These reports track the progress of each protocol within the CTN from the date of first randomization to final closeout and publication of main results. The TPR and DSR summarizes data over multiple protocols and provides detailed trial-specific information. The content includes areas from all aspects of the clinical trials including enrollment, retention, QA and regulatory. For ongoing studies, these reports are updated regularly (daily to monthly, depending on the report). On a monthly basis, the TPR is archived to allow review by study leadership. Reports on Completed Studies are also provided and can be viewed by clicking on "CTN Summary Reports".
