Department of Health and Human Services May 22, 2018 – Federal Register Recent Federal Regulation Documents

The Food and Drug Administration (FDA) is establishing a public docket to assist with the development of a policy or guidance document on the assessment of pH-dependent drug-drug interactions (DDIs). In October 2017, FDA published two draft guidance documents on DDIs entitled ``In Vitro Metabolism- and Transporter-Mediated Drug-Drug Interaction Studies'' (In Vitro Studies Draft Guidance) and ``Clinical Drug Interaction StudiesStudy Design, Data Analysis, and Clinical Implications'' (Clinical Drug Interaction Studies Draft Guidance). These two draft guidances focus on enzyme- and transporter-based DDIs and do not include a framework to assess pH-dependent DDIs. FDA is seeking public input on best practices in the planning and evaluation of pH-dependent DDIs.

The Food and Drug Administration (FDA) is publishing a list of premarket approval applications (PMAs) that have been approved. This list is intended to inform the public of the availability of safety and effectiveness summaries of approved PMAs through the internet and the Agency's Dockets Management Staff.

The Food and Drug Administration (FDA, Agency, or we) is announcing an opportunity for public comment on the proposed collection of certain information by the Agency. Under the Paperwork Reduction Act of 1995 (PRA), Federal Agencies are required to publish notice in the Federal Register concerning each proposed collection of information, including each proposed extension of an existing collection of information and to allow 60 days for public comment in response to the notice. This notice solicits comments on controlled correspondence related to generic drug development.
