Biologics 2002 Comparability of Biotechnology Products

The globalization of research and development considering collaborative arrangements among companies for producing biotechnology-derived products often raises product comparability issues which are expected to increase in frequency and complexity. This volume reviews current scientific developments and regulatory issues relating to establishing comparability of biological products when manufactured within a single company or jointly among two or more companies (e.g. manufacturing changes, site changes). Recommendations for a framework constituting a harmonized document on comparability are also provided. A cadre of international regulatory and industry experts concluded and recommended that a) the unprecedented record of product safety enjoyed by the biotech industry is founded on the vigilance dedicated to process controls and product quality throughout the drug development continuum; b) intra-manufacturer process changes are in line with modern global practices, scientific and economic considerations; c) the innovators proprietary development history, production experience, training, validated assays and standards constitute a solid basis for performing legitimate and scientifically rigorous comparisons of products when introducing manufacturing changes. Importantly, depending on the nature of the product, at times, comparisons may dictate expanded investigations in clinical trials; d) comparability, while robust in concept and application within one manufacturers product, is not a surrogate for establishing inter-manufacturer therapeutic equivalence which is the foundation for 'generic products; e) an international harmonized approach guidance document is timely. Summarizing current thinking and practical experience, these proceedings should be read by academic, industry, and regulatory scientists who work with biological products prepared for use as vaccines, plasma derivatives, or therapeutic products.Brown, F. is the author of 'Biologics 2002 Comparability of Biotechnology Products' with ISBN 9783805574273 and ISBN 3805574274.
