The Food and Drug Administration Amendments Act of 2007 (FDAAA) expanded the public reporting requirements for “applicable clinical trials” involving certain drugs, biologicals, and devices. In December 2008, the Food and Drug Administration (FDA) issued a draft guidance document proposing, among other things, definitions that would affect who would be required to register certain clinical trials under the FDAAA. In some cases, FDA's proposal would require manufacturers who make grants to investigators to be the responsible party required to register. In addition, FDA elaborates on the circumstances under which clinical investigations designed to demonstrate bioequivalency would be subject to reporting. Additional background information is available at the clinicaltrials.gov web site.
