  1. 1. Regulatory and QA Considerations for Drug Product Development Louise Johnson, M.S. Chinese American Biopharmaceutical Society Meeting June 5, 2010
  2. 2. Core Principles <ul><li>Patient safety guides FDA’s review of CMC information during development </li></ul><ul><li>CMC development proceeds simultaneously with clinical development </li></ul><ul><li>Data generated during development builds upon early work and should be planned to compose a complete NDA CMC section that supports product approval </li></ul>
  3. 3. Topics <ul><li>CMC goals in development </li></ul><ul><li>Standards for product quality </li></ul><ul><ul><li>Good Manufacturing Practice (GMP) </li></ul></ul><ul><ul><li>Quality Assurance (QA) </li></ul></ul><ul><li>Quality Assurance and Quality Control </li></ul><ul><li>CMC Information for Original INDs </li></ul><ul><li>CMC Information as Development Progresses </li></ul><ul><li>NDA Planning </li></ul>
  4. 4. CMC Development Goals <ul><li>Manufacture the drug product in a manner so that you can assure its identity, strength, quality, and purity* </li></ul><ul><li>Create documentation of your processes so that you can demonstrate to FDA that you understand the critical characteristics of the product and the process and can reliably manufacture a high quality product </li></ul><ul><li>* FD&C Act Section 505(d)(3) </li></ul>
  5. 5. Standards Used to Ensure Product Quality <ul><li>GMP – Good Manufacturing Practice (21 CFR 210 and 211) </li></ul><ul><ul><li>A standard for the production and testing of a pharmaceutical or device to ensure product quality </li></ul></ul><ul><ul><li>Required for human use </li></ul></ul><ul><ul><li>Not required for animal studies </li></ul></ul><ul><ul><ul><li>However, there are GLP requirements for study material </li></ul></ul></ul><ul><ul><li>Described in the Food, Drug & Cosmetic Act and FDA regulations </li></ul></ul><ul><li>Quality Assurance (QA) </li></ul><ul><ul><li>All those planned and systematic production processes that are established to ensure the investigational product is fit for the intended purpose </li></ul></ul><ul><li>Quality By Design (QbD) </li></ul><ul><ul><li>A systematic approach to development that begins with predefined objectives and emphasizes product and process understanding and process control, based on sound science and quality risk management </li></ul></ul><ul><ul><li>Provides a basis for risk management and increased regulatory flexibility after NDA approval </li></ul></ul>
  6. 6. Principles Underlying GMP <ul><li>Right the first time (can’t inspect quality in) </li></ul><ul><li>Documentation of all actions and decisions </li></ul><ul><li>Double checking work & calculations </li></ul><ul><li>Establish acceptance criteria – specifications </li></ul><ul><li>Analytical testing to confirm product characteristics </li></ul><ul><li>Define standard processes for manufacturing and analytical testing in writing </li></ul><ul><li>Final product release by personnel independent of manufacturing department </li></ul><ul><li>Personnel qualified by education and training </li></ul><ul><li>Label, segregate, and control components & equipment </li></ul>
  7. 7. Regulatory Affairs Function <ul><li>Act as liaison between the company and FDA </li></ul><ul><li>Make all regulatory submissions </li></ul><ul><li>Advise on current regulatory requirements, guidance, and agency activities </li></ul>
  8. 8. Quality Assurance Function <ul><li>Responsible for independent, objective assessment of manufacturing systems and operations </li></ul><ul><li>Responsible for lot release, Certificates of Analysis </li></ul><ul><li>Manages SOPs, revisions, distribution </li></ul><ul><li>Provides GMP training </li></ul><ul><li>Audits facilities, operations, documentation </li></ul><ul><li>Manages change control </li></ul>
  9. 9. Quality Control Function <ul><li>Sample, test, and report results for starting materials, excipients, API, final product </li></ul><ul><li>Perform line checks </li></ul><ul><li>Involved in the manufacturing process </li></ul>

  11. 11. So What CMC Information Is Needed At Each Stage Of Development? <ul><li>Regulations allow great deal of flexibility in the amount and depth of data </li></ul><ul><li>The type of information needed will depend on </li></ul><ul><ul><li>Phase of investigation (Phase 1, 2, or 3) </li></ul></ul><ul><ul><li>Specifics of the human study proposed (dose regimen, duration of dosing) </li></ul></ul><ul><ul><li>Nature and source of the drug substance (synthetic, animal source) </li></ul></ul><ul><ul><li>Drug product dosage form (oral, IV) </li></ul></ul>
  12. 12. CMC Information for Original IND <ul><li>Sufficient information for evaluation of the safety of the proposed investigational product </li></ul><ul><li>Data relating the clinical supplies to the drug used in the animal toxicology studies that support the safety of the proposed human study </li></ul><ul><li>Statement of whether you believe there are signals of potential human risk in: </li></ul><ul><ul><li>the chemistry of either the drug substance or the drug product or </li></ul></ul><ul><ul><li>the manufacturing of either the drug substance or the drug product </li></ul></ul>
  13. 13. IND for Phase 1 Study <ul><li>Identification of a safety concern or insufficient data to evaluate safety are the only CMC reasons for a clinical hold </li></ul><ul><li>Special note: While FDA has exempted Phase 1 clinical supplies from GMP regulations, the Federal Food, Drug, and Cosmetic Act still requires clinical supplies to be manufactured under GMP </li></ul><ul><ul><li>Section 501(a)(1)(B) of the FD&C Act </li></ul></ul>
