I. Background

On February 7, 2007, FDA held a public meeting to solicit comments on issues that FDA should consider if it decides to propose revisions to § 314.70 (21 CFR 314.70) regarding CMC supplements and other changes to approved marketing applications for human drugs. In the notice announcing the public meeting (72 FR 574), FDA stated that current § 314.70 categorizes postapproval CMC changes and their associated reporting requirements without consideration of the applicant's risk management activities or internal quality systems and practices; therefore, § 314.70 reflects a rules-based, or prescriptive, approach to regulating postapproval manufacturing changes. Current § 314.70 may create regulatory burdens and costs that discourage beneficial manufacturing changes and may not support a desirable level of innovation, modernization, and flexibility for the industry as described in FDA's pharmaceutical current good manufacturing practices for the 21st century initiative (CGMP Initiative). Consistent with the agency's risk-based approach to regulating pharmaceutical manufacturing described in the CGMP Initiative, FDA is considering possible revisions to § 314.70 to allow for more manufacturing changes to be made without prior FDA approval using a firm's internal change control system and to allow for consideration of risk-based approaches based on manufacturing process understanding, including prior knowledge of similar products, and overall quality systems to provide an enhanced risk-based approach to the CMC regulatory process.

Interested persons were given until March 7, 2007, to submit written or electronic comments to the agency related to the focus of the public meeting. As a result of continued public interest, FDA is reopening the comment period until May 18, 2007, to allow interested persons additional time to submit comments.
