CTTI’s State of Clinical Trials Project set out to facilitate the analyses of data in ClinicalTrials.gov, by creating the database for Aggregate Analysis of ClincalTrials.gov (AACT), a restructured and reformatted relational database developed using publicly available and downloadable data from ClinicalTrials.gov. Since the original AACT was created in 2010, we’ve continued to regularly issue updated versions of the database.

The latest version of the AACT Database is now available on the CTTI website, along with the supporting documents. This dataset reflects data downloaded from ClinicalTrials.gov in March 2015. To assist users with interpretation of the data, high level and comprehensive data dictionaries and a points to consider document are also located on the CTTI website. Previous versions of AACT are available as well.

Since CTTI released the first AACT database five years ago, it has been utilized to answer many questions regarding the landscape of clinical trials. For a list of peer-reviewed publications that have assessed the state of trials within medical specialties, CLICK HERE.
