This revised and updated fourth edition provides a comprehensive overview of
validation methodologies applicable in the manufacturing process of various
pharmaceuticals. This reference may be viewed as a guide to developing rational
control processes to ensure the quality of pharmaceutical products. This
edition includes new topics related to biologics and single-use technologies.
This book aims to offer a comprehensive guide to developing and controlling
pharmaceutical manufacturing processes to ensure the safety and quality of the
products. For the past several years, the FDA has been promoting the concept of
Quality by Design (QBD) to manufacture safe and effective drug products.
Validation refers to the essential controls or evidence-based documented
processes that consistently provide a high degree of quality assurance of
manufacturing quality products. This reference provides a theoretical and
practical basis for consistently establishing processes to produce products
with predetermined specifications. Therefore, the objectives of this book are
valuable to pharmaceutical industry professionals.
According to the authors, this reference would be helpful to all "industry
professionals." This reference is a valuable guide to individuals concerned
about the process validation in pharmaceutical manufacturing. Similar to the
previous editions, this fourth edition is expected to be well utilized by the
professionals working in process validation. The authors are reputable industry
professionals. The contributors are primarily from the industry with relevant
experience.
This book should be considered as a reference guide to pharmaceutical process
validation. In 67 chapters, this reference presents content related to the
conceptual framework and the practical aspects of developing and controlling
pharmaceutical processes to ensure product quality. The fundamental aspects of
pharmaceutical process validation have been expanded from the previous edition.
A few new chapters have been added. The new topics include gene therapy and
single-use technologies. The new chapters on process validation of combination
products, nanotechnology, disposable system, and medical device manufacturing
are expected to be informative and valuable to industry professionals. The
authors' years of industry experience have helped them discuss the challenges
and opportunities in various stages of a validation program. The authors'
insight into the solutions for possible challenges in process validation is
expected to be helpful to the target audience. The chapter on process
validation for cell and gene therapies succinctly provides insight into the
complexity of and current trends in process validation of biotechnology-based
products. The interested audience will well utilize the information to make
strategic decisions about the validation of bioprocessing. The reference
provides discussions on Six Sigma approaches toward process validation. In
addition, discussions on Process Analytical Technology and Validation and
Computerized Systems Validation are practical from the industry perspective.
The authors have shared their perspectives on the future of validation in a
short chapter, which readers are expected to find interesting. There are three
chapters on approaches to validation in the United States, Europe, and Japan.
People working in multinational pharmaceutical companies should find those
chapters handy. The authors have provided sufficient flow charts and diagrams
to facilitate understanding. The reference has become voluminous to include
relevant topics. Therefore, it could be developed in two or three volumes. Some
of the image quality could be improved.
This reference provides theoretical and practical considerations in identifying
critical process control issues related to the manufacturing of
pharmaceuticals. This fourth edition has a few new topics related to emerging
trends in pharmaceutical preparations. Pharmaceutical scientists,
manufacturers, engineers, drug quality assurance and regulatory personnel,
project and program managers, and information system professionals are expected
to benefit from this reference. A few books are available related to this
subject matter, but they are not as comprehensive as this one. This book will
serve its purpose as a reference guide. New chapters have enriched this fourth
edition.

James Agalloco is president of Agalloco & Associates, which provides a range of technical services to the pharmaceutical and biotechnology industry. Since the formation of the company in 1991, Agalloco has assisted more than 100 healthcare firms in a wide range of validation, automation and compliance areas. During his more than 35 years of industry experience, he has worked in organic synthesis, pharmaceutical formulation, pharmaceutical production, project and process engineering, validation and process automation during his career at Merck, Pfizer, Squibb and Bristol-Myers Squibb.
The guidance document covers validation largely at a conceptual level and avoids narrow precepts and specific examples. This approach is appropriate because the document addresses the subject from active pharmaceutical ingredient (API) production (by either chemical synthesis or biological processes) through drug-product production for all pharmaceutical dosage forms. The intended breadth of coverage embraces a myriad of unit operations in the preparation and manufacture of these products. Unstated is whether the draft guidance is intended to be applied to supportive processes that are not an inherent part of the formulation process. Among the support processes are cleaning, inspection, sterilization, and aseptic processing. Each of these processes can be an essential part of pharmaceutical manufacture that requires validation.
Initial and ongoing qualification of production processes are the means for establishing and confirming the experimental experience at significantly larger scales of operation. Knowledge gleaned from the development simplifies later activities. Production processes are always operated within the defined operating ranges because there is no reason to experiment with conditions at the extreme ends of the ranges on this larger scale. Challenges during these stages are primarily in the number of tests performed on the produced materials. Qualification lots are customarily sampled at a substantially higher rate than are routine production lots, and testing of these expanded samples is the challenge of the commercial process. The guidance recommends using appropriate statistical tools in the full-scale qualification efforts to provide the desired confidence in process and product acceptability and thus attain the desired validated state. The expectations for statistical evidence in process validation are well founded; sampling batches at the modest levels associated with pharmacopeial tests provide little, if any, proof of end-product quality. Although those tests may be legally binding, they have only limited value. Industry has largely ignored the levels of "real quality" needed to support its claims for patient welfare (4).
