The latest revision to the Federal Policy for the Protection of Human Subjects ("Common Rule") will kick in later to allow more time for organizations to implement the requirements and for stakeholders to comment about whether there is need for an additional delay.
The January 22, 2018 Federal Register notice moves the Common Rule’s effective date forward six months, from January 19 to July 19, 2018. The federal departments and agencies listed in the notice plan to propose a further delay.
In practice, NIH has already incorporated many of the policy's human subjects protections into NIH-level requirements. For example, this delay won't affect the implementation of NIH's single institutional review board policy.
Through March 19, 2018, you can comment to share your opinion on the proposal for a further implementation delay. Get details on the comment process from the notice.
