An expanded database for clinical trials, developed and administered by the NLM in collaboration with the Food and Drug Administration (FDA), will now include results from clinical trials, in addition to trial registrations.

Results from clinical trials will be integrated into the clinical trial records and can be accessed through MedlinePlus, which links to information on some 750 diseases and health conditions.

Recent legislation mandates that scientists conducting trials sponsored by the NIH, or other federal agencies, provide summary results for a broad range of trials of drugs, medical devices and biological products that have been approved by the FDA. Patient-identifiable information will not be included.

Since 2000, the ClinicalTrials.gov database, the largest single registry of clinical trials, has provided patients, families and the public easy access to information about a trial’s purpose, who may participate, locations, and phone numbers for additional details. The Web site currently has information on nearly 62,000 ongoing and completed trials in all 50 states and 157 countries sponsored by the government, pharmaceutical industry, academic and international organizations.
