A systematic approach leads the reader through a process, outlining the understanding of the critical quality attributes of the molecule, the development of the design space to meet the quality attributes, filing of the QbD information in regulatory documents, risk management, and the application of QbD. Complete with real world case studies, this is a core reference for scientists in the biopharmaceutical industry, regulatory agencies, and students.
Anurag S. Rathore received his PhD in chemical engineering from Yale University and is the Director of Process Development, Amgen Inc. His areas of interest include process development, scale-up, technology transfer, process validation, process analytical technology, and quality by design. He has authored more than 100 publications and presentations in these areas and serves on the editorial advisory boards for Biotechnology Progress, BioPharm International, Pharmaceutical Technology Europe, Journal of Biochemical and Biophysical Methods, and Separation and Purification Reviews. Rohin Mhatre is a Senior Director in the BioProcess Development department at Biogen Idec, Cambridge, Massachusetts, and has been with the company since 1996. His group is responsible for development of analytical methods and product characterization to support the process and formulation development of early and late stage clinical programs. Mhatre is also leading the QbD initiative within Biogen Idec. He has authored several publications and been an invited speaker to numerous scientific meetings.
