History and Evolution of ClinicalTrials.gov
ClinicalTrials.gov was launched in 2000 as a result of the Food and Drug Administration Modernization Act (FDAMA) of 1997, which mandated the creation of a clinical trial registry. Initially, the database focused on trials for serious or life-threatening conditions, but its scope has since expanded to include a broader range of diseases and conditions. Over the years, ClinicalTrials.gov has undergone several updates and enhancements, incorporating new features and functionalities to improve user experience and data quality.
The database has become an essential tool for clinical trial registration, results reporting, and data sharing. In 2007, the FDA Amendments Act (FDAAA) further expanded the requirements for clinical trial registration and results reporting, reinforcing the importance of ClinicalTrials.gov in promoting transparency and accountability in clinical research. Today, the database is widely recognized as a model for clinical trial registries worldwide, setting standards for data quality, accessibility, and usability.
