The Alzheimer's disease clinical trials database is a joint project of the FDA and the National Institute on Aging (NIA). It is maintained by NIA's Alzheimer's Disease Education and Referral Center. See the fact sheet on Participating in Alzheimer's research: For Yourself and Future Generations for more information.
The National Cancer Institute (NCI) is the U.S. Government's principal agency for cancer research and training. Most other U.S. Government agencies that conduct cancer research, such as the U.S. Department of Defense and the U.S. Department of Veterans Affairs, do so in partnership with NCI.
Visit NCI's Clinical Trials page to find information on cancer studies, read about noteworthy clinical studies, find resources for researchers, and browse clinical studies results by type of cancer.
NCI's Publications Locator page provides access to publications that help individuals and health care professionals understand clinical studies. These include self-paced workbooks, booklets, DVDs, slide programs on CD-ROM, and online training courses.
