ClinicalTrials.gov is a comprehensive online database that provides detailed information on clinical trials conducted in the United States and around the world. The database is maintained by the National Library of Medicine (NLM) at the National Institutes of Health (NIH) and is a valuable resource for patients, researchers, and healthcare professionals. In this article, we will delve into the workings of ClinicalTrials.gov, its history, and its significance in the clinical trial landscape.
History and Purpose of ClinicalTrials.gov
ClinicalTrials.gov was launched in 2000 as a result of the Food and Drug Administration Modernization Act (FDAMA) of 1997. The database was created to provide a centralized repository of clinical trial information, making it easier for patients, researchers, and healthcare professionals to find and access information on ongoing and completed clinical trials. The primary purpose of ClinicalTrials.gov is to increase transparency and accountability in clinical trial research, improve patient recruitment and retention, and enhance the overall quality of clinical trials.
How ClinicalTrials.gov Works
ClinicalTrials.gov is a web-based database that allows users to search for clinical trials by keyword, location, disease or condition, and other criteria. The database contains information on over 300,000 clinical trials, including trials sponsored by the NIH, other federal agencies, and private industry. Each clinical trial record includes detailed information on the trial’s purpose, design, eligibility criteria, interventions, and outcomes. Users can also search for trials by location, disease or condition, and trial status.
| Clinical Trial Phase | Description |
|---|---|
| Phase 1 | Initial human trials to assess safety and tolerability |
| Phase 2 | Trial to assess efficacy and side effects |
| Phase 3 | Larger trials to confirm efficacy and monitor side effects |
| Phase 4 | Post-marketing trials to monitor long-term safety and efficacy |
