In the United States, where it is mandatory to register clinical trials for
serious or life threatening diseases, many such trials are not listed
in any publicly available trials register. Manheimer and Anderson (p 528)
used major US trial registers to search for information on 33 phase
III trials of drugs known to be under investigation for prostate and
colon cancer: about 34% were not identified in any of the registers.
The authors conclude that, despite the existence of hundreds of
predominantly online registers of drug trials, information is
incomplete, with non-standardised language, and is unlikely to meet
the needs of clinicians and others.
