Principles And Practices Of Lyophilization In Product Development And Manufacturing

The biotechnology/biopharmaceutical sector has tremendously grown which led to the invention of engineered antibodies such as Antibody Drug Conjugates (ADCs), Bispecific T cell engager ( BITES), Dual Variable Domain ( DVD), Chimeric Antigen Receptor - Modified Tcells (CART) that are currently being used as therapeutic agents for immunology and oncology disease conditions. In addition to other pharmaceuticals and biopharmaceuticals, all these novel formats are fragile with respect to their stability/structure under processing conditions meaning marginal stability in the liquid state and often require lyophilization to enhance their stability and shelf-life. This book contains chapters/topics that will describe every aspect of the lyophilization process and product development and manufacturing starting from the overview of lyophilization process, equipment required, characterization of the material, design and development of the formulation and lyophilization process, various techniques for characterization of the product, scale-up/tech-transfer and validation. It also describes the application of CFD coupled with mathematical modeling in the lyophilization process and product development, scale-up, and manufacturing. Additionally, Principles and Practice of Lyophilization Process and Product Development contains an entire dedicated section on “Preservation of Biologicals” comprised of nine chapters written by experts and including case studies.

Finding consistent, analytical discussions of processes and principles of lyophilization can be challenging and often frustrating. The first resource to gather information about the field, Lyophilization: Introduction and Basic Principles is still the book to have on lyophilization. Presenting information in an easy-to-read style, the book comprehensively and authoritatively covers the field. Using plain, unpretentious language, author Thomas A. Jennings pulls together information from diverse sources to provide an authoritative compendium of the lyophilization process and its basic principles. He provides important discussions about the nature of the container-closure system and the equipment, tools, and environments required. Case studies and examples of solutions illustrate the many ways problems can be addressed in the lyophilization process. The book covers: Properties of lyophilized materials Product formulation requirements and the thermal properties of formulations Importance of process water Phase changes Thermal analytical methods Freezing, primary, and secondary drying processes Effect of vacuum freeze-dryers, both now and in the future Including over 150 illustrations, global symbols, and more than 350 references, this book is the complete guide to lyophilization, its analytical methods, measurement of process parameters, and equipment.

This comprehensive book encompasses various facets of sterile product development. Key concepts relevant to the successful development of sterile products are illustrated through case studies and are covered under three sections in this book: • Formulation approaches that discuss a variety of dosage forms including protein therapeutics, lipid-based controlled delivery systems, PEGylated biotherapeutics, nasal dosage form, and vaccines • Process, container closure and delivery considerations including freeze-thaw process challenges, best practices for technology transfer to enable commercial product development, innovations and advancement in aseptic fill-finish operations, approaches to manufacturing lyophilized parenteral products, pen / auto-injector delivery devices, and associated container closure integrity testing hurdles for sterile product closures • Regulatory and quality aspects in the areas of particulate matter and appearance evaluation, sterile filtration, admixture compatibility considerations, sterilization process considerations, microbial contamination investigations and validation of rapid microbiological methods, and dry and moist heat sterilizers This book is a useful resource to scientists and researchers in both industry and academia, and it gives process and product development engineers insight into current industry practices and evolving regulatory expectations for sterile product development.

Aimed at product and process developers in the biopharmaceutical industry and academia, this is the first book to describe freeze-drying, as related to the pharmaceutical industry.

Highlights the application of freeze-drying to pharmaceuticals-illustrating practical & industry-tested methods of preserving & reactivating delicate biologicals & biochemicals. Discusses the basic principles & engineering aspects of lyophilization, & also the role of bulking agents, additives, cryoprotectants, antioxidants, free radicals, & other products that protect the biological integrity of active substances during freezing, drying, & storage.

Freeze-drying is an important preservation technique for heat-sensitive pharmaceuticals and foods. Products are first frozen, then dried in a vacuum at low temperature by sublimation and desorption, rather than by the application of heat. The resulting items can be stored at room temperature for long periods. This informative text addresses both principles and practice in this area. The first chapter introduces freeze-drying. The authors then review the fundamentals of the technique, heat-mass transfer analyses, modelling of the drying process and the equipment employed. Further chapters focus on freeze-drying of food, freeze-drying of pharmaceuticals and the protective agents and additives applied. The final chapter covers the important subjects of disinfection, sterilization and process validation. Freeze-drying of pharmaceutical and food products is an essential reference for food, pharmaceutical and refrigeration engineers and scientists with an interest in preservation techniques. It will also be of use to students in these fields. Addresses the principles and practices used in this important preservation technique Explains the fundamentals of heat-mass transfer analysis, modelling and the equipment used Discusses the importance of disinfection, sterilization and process validation

Freeze Drying of Pharmaceutical Products provides an overview of the most recent and cutting-edge developments and technologies in the field, focusing on formulation developments and process monitoring and considering new technologies for process development. This book contains case studies from freeze dryer manufacturers and pharmaceutical companies for readers in industry and academia. It was contributed to by lyophilization experts to create a detailed analysis of the subject matter, organically presenting recent advancements in freeze-drying research and technology.
