This book is intended to serve as a source of practical, technicalinformation for those persons in the biotechnology industry. Casestudies and/ or actual industry examples are used to support the textwherever possible. While much of the material contained within thistext is equally applicable to nonbiopharmaceutical processes, theemphasis has been focused directly upon biopharmaceuticalmanufacturing.Section I provides an in-depth analysis of the design concepts thatlead to cleanable equipment. Also covered in the tirst section arecleaning mechanisms and cleaning systems. The first section isparticularly useful to those persons faced with the task of designingsystems that will be cleaned and also provides the biochemicaloockground of the mechanisms associated with the removal of commonbiotechnology soils.Section II focuses on cleaning validation concepts. While thematerial is equally useful for single product cleaning, emphasis isplaced upon multiproduct cleaning validation. Included in Section IIare general validation principles as thex apply to cleaning validation, detailed analxsis of cleaning process validation, sampling techniques, analytical methods and acceptance criteria. The material in this sectionwill be useful to anyone responsible for the development of a cleaningvalidation program.The final section, Section Ill, provides an overview of multiproductbiotechnology manufacturing procedures. Included in this section is ananalysis of tne risk-to-benefit scenarios associated with the various formsof product manufacturing, analysis of changeover programs, ~uipmentconsiderations, and material transfer systems as they are affected bymultiproduct manufacturing strategies.
