E6-22588. Supplements and Other Changes to an Approved Application; Public Meeting

AGENCY:

Food and Drug Administration, HHS.

ACTION:

Notice of public meeting.

SUMMARY:

The Food and Drug Administration (FDA) is announcing a public meeting to solicit comments on issues that FDA should consider when developing revisions to its regulations regarding chemistry, manufacturing, and controls (CMC) supplements and other changes to approved marketing applications for human drugs. FDA is evaluating how it could revise its regulations 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, which would reduce the number of supplements. We will consider the input from the public meeting and comments on the issues presented in this document as we consider whether to revise our regulations.

DATES:

The public meeting will be held on February 7, 2007, from 8:30 a.m. to 3:30 p.m. Anyone who wishes to speak at the meeting must register and submit a summary of the presentation by January 24, 2007, and submit an electronic copy of the presentation by January 31, 2007. See section III of the SUPPLEMENTARY INFORMATION section of this document for details on how to register. Submit written or electronic comments by March 7, 2007.

ADDRESSES:

The public meeting will be held at the Food and Drug Administration, Center for Drug Evaluation and Research Conference Room, 7519 Standish Pl., third floor, rm. A, Rockville, MD 20855. There is parking near the building. Photo identification is required to clear building security.

Submit written comments to the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852. Submit electronic comments to http://www.fda.gov/​dockets/​ecomments.

SUPPLEMENTARY INFORMATION:

I. Background

In the Federal Register of June 28, 1999 (64 FR 34608), FDA published a proposed rule to implement section 116 of the Food and Drug Administration Modernization Act (FDAMA)^[1] by amending certain regulations including § 314.70 (21 CFR 314.70) regarding supplements and other changes to approved human new drug and abbreviated new drug marketing applications. In the Federal Register of April 8, 2004 (69 FR 18728), FDA published the final rule (final rule) implementing these changes. Section 314.70, as amended, requires manufacturers to assess the effects of manufacturing changes on the identity, strength, quality, purity, and potency of a drug as those factors relate to the safety or effectiveness of the product, and categorizes all changes beyond the established variations in an approved NDA or ANDA into one of three groups—major, moderate, or minor. Major changes require an applicant to submit and receive FDA approval of a supplement before distribution of the product made with the manufacturing change. Moderate changes require an applicant to submit a supplement at least 30 days before distribution of the product or, in some cases, submit a supplement at the time of distribution. Minor changes require an applicant to notify FDA of the changes in an annual report.

In August 2002, FDA introduced the Pharmaceutical Current Good Manufacturing Practices (CGMPs) for the 21st Century Initiative (CGMP Initiative, available on the Internet at http://www.fda.gov/​cder/​gmp/​index.htm) to enhance and modernize the regulation of pharmaceutical manufacturing and product quality. In September 2004 (after publication of the final rule), FDA published a final report on “Pharmaceutical CGMPs for the 21st Century—A Risk-Based Approach” (http://www.fda.gov/​cder/​gmp/​gmp2004/​GMP_​finalreport2004.htm). As explained in the report, FDA regulates pharmaceutical manufacturing to ensure that the drug supply in the United States is of consistently high quality. Because of critical public health implications of drug manufacturing, FDA traditionally has exercised extensive control over virtually every aspect of the manufacturing process. This regulatory approach has contributed to pharmaceutical companies being reluctant to change their manufacturing processes and equipment. In recent years, significant advances in pharmaceutical manufacturing science, modern quality management systems, and risk management approaches have taken place. This has yielded new tools that can be used to help ensure manufacturing quality. The new tools enable manufacturers to detect, analyze, correct, and prevent problems and continuously improve their manufacturing processes. It has been the goal of the CGMP Initiative to create a regulatory paradigm that will encourage pharmaceutical manufacturers to use these new tools to facilitate their decision making and implementation of manufacturing processes to reliably produce pharmaceuticals of high quality. Under the new paradigm, as under the current scheme, pharmaceutical manufacturers are ultimately responsible for ensuring the quality of their products subject to FDA regulatory oversight.

The 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. The 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 the 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. In particular, FDA is evaluating how it could revise § 314.70 to allow for more manufacturing changes to be made without prior FDA approval using a firm's internal change control system. FDA also is evaluating how it could revise § 314.70 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. To accomplish this objective, FDA is considering redefining what FDA considers to be a major manufacturing change, reducing the reporting burden for certain changes, and creating a new reporting category of manufacturing changes that do not require notification to FDA. FDA anticipates that these revisions would reduce the number of postapproval supplements that are required to be submitted. We emphasize that under a new regulatory scheme, although the reporting burdens for certain manufacturing changes would be reduced, manufacturers will continue to be responsible for ensuring product quality. FDA also is considering an approach that would retain aspects of the current regulatory scheme to accommodate those manufacturers who choose to continue operating within the current regulatory framework. FDA is announcing this public meeting to solicit comments on issues that should be considered if FDA decides to propose revisions to § 314.70.

II. Questions for Discussion and Comment

FDA has prepared the following questions to help focus the comments that will be presented at the public meeting or otherwise communicated to the agency. Those who comment are invited to address any or all of these questions, or raise other issues.

1. Is it valuable for the agency to move toward a more risk-based and quality systems oriented strategy for regulating postapproval CMC changes outside of the formal application review process? What are the advantages and/or disadvantages?

2. Would revising § 314.70 as described in this notice provide the same level of protection to the public as the current regulatory scheme with respect to ensuring the safety and efficacy of human drugs? What inspectional approaches might the agency consider to evaluate manufacturing changes while ensuring public safety?

3. Would revising § 314.70 as described in this notice change the regulatory burden on the pharmaceutical industry? If so, how would the burden change?

4. Would reducing the prescriptiveness of § 314.70 provide manufacturers with greater regulatory flexibility? Would it encourage manufacturers to adopt CMC-related risk management strategies? Would there be disadvantages?
