OHRP Archive of Historical and Replaced Materials

The HHS Office for Human Research Protections (OHRP) has placed a number of historical and superseded documents in this separate archive area. These documents are accessible to the public for research and informational purposes, but should not be regarded as reflecting current HHS or OHRP policy.

Please note that search results in the archive area include only historical and superseded documents. This is intended to help avoid confusion with current policy and guidance documents.
