IPQ Special Report — September/October 2007 in Review

APPLYING  QUALITY  BY  DESIGN  TO  BIOPHARMACEUTICALS is testing the viability of the definitions that have been jelling in the small-molecule context. Establishing the linkage between quality attributes and clinical performance – a foundation block for the quality-by-design structure – is a particular challenge in the biotech arena, and pathways for tightening this linkage are being explored and discussed. At recent workshops on QbD for biopharmaceuticals, participants analyzed where the biotech industry is on the learning curve and shared ideas on how to advance the progress. A QbD biotech submission pilot, expanded comparability protocols for defining the design space and reducing change filing burdens, and a consortium to pull together knowledge on the product attribute/clinical performance relationship are among the ideas on the table in the U.S. Regulators and industry are also meeting in Europe to advance the QbD initiative in the biopharmaceutical area. Implementation of the ICH guidelines Q8-10 for both drugs and biologics is drawing debate, and an industry initiative is underway to help solve the practical problems involved.
