FDA Announces Planned Withdrawal, Revision of Dozens of Guidance Documents

New Initiative

Writing in the 7 August 2013 edition of the Federal Register, FDA notes that CDER is embarking on a new initiative, one prompted by its September 2000 issuance of its Good Guidance Practices (GGP) regulation.  FDA explained, “The GGP regulation describes FDA policies and procedures for the development, issuance, and use of guidance documents and makes these Agency policies and procedures clear to the public.  The GGP regulation provides for developing and issuing guidances that set forth initial interpretations of statutory or regulatory requirements, explain changes in interpretation of policies that are of other than minor in nature, or discuss complex scientific issues or highly controversial issues.”  And, important for the purposes of its upcoming activities, the GGP regulation also directs FDA to “periodically review” its existing stockpile of guidance documents to determine whether they need minor changes, major changes, or to be withdrawn entirely due to either irrelevance or other factors.

Focus on Finalizing

As part of those minor and major changes, FDA said it wants to finalize some of the many draft guidance documents it has issued.  These documents are often published with the intent of obtaining industry and public feedback, but the agency conceded that it does not always have time to finalize the documents “because of higher staff priorities.”  While the documents are not referenced quite as often as final guidance documents, FDA has nevertheless referenced them in its Warning Letters to companies.  For example, a May 2012 letter to a pharmaceutical company critiques the design and layout of the facility, and calls on the company to reference the best practices established in a draft guidance document, since finalized.  In other words, because a guidance document only clarifies the agency’s thinking (as opposed to a regulation, which is official policy as directed by statute), a draft guidance document can carry the same weight as a final draft guidance document.

To Be Withdrawn: 23 Guidances

The Federal Register notice indicates that FDA has already identified 23 draft guidance documents in need of withdrawal. “In most cases, FDA has developed other guidances and resources to assist industry with clinical evaluation and requirements for drug approval,” the agency writes.

Still to Come: Revisions

In addition, FDA said it had identified a large number of guidance documents for revision and finalization, and is in the midst of “developing a plan for their completion.” Those documents are related to the following topics:

  • Biopharmaceutics;
  • Chemistry, manufacturing, and controls;
  • Clinical pharmacology;
  • Combination products;
  • cGMP compliance;
  • Development of antimicrobial drugs;
  • Drug advertisements;
  • Drug safety;
  • Electronic submissions;
  • Labeling;
  • OTC products;
  • Pharmacology and toxicology;
