Responding to an FDA Form 483: A Five-Step Approach

by

When the US Food and Drug Administration (FDA) inspects your company’s biomanufacturing facility, investigators use the FDA Form 483 to record observations and findings (1). Such inspections typically review all good manufacturing practices and good laboratory practices (GxP) quality systems documents. If those investigators find compliance issues, they deliver a summary of their observations and findings using a Form 483, a copy of which will be provided to your company at the end of the inspection visit. How to Respond…

Bridging Analytical Methods for Release and Stability Testing: Technical, Quality and Regulatory Considerations

by , , , , , , , , , and

To monitor the control and consistency of products derived from biological systems, a broad array of analytical methods are used for biopharmaceutical release and stability testing. These methods include both classical and state-of-the-art technologies as well as new technologies as they emerge over time.During the life cycle of a product, several reasons can arise for making changes in existing analytical methods: e.g., improved sensitivity, specificity, or accuracy; increased operational robustness; streamlined workflows; shortened testing times; and lowered cost of testing.…

Process- and Product-Relate Impurities: Part 1 – Process-Related Impurities An Overview

by and

Introduction by Cheryl Scott The CMC Strategy Forums focus on relevant chemistry, manufacturing, and controls (CMC) issues throughout the life cycle of a therapeutic and thereby foster collaborative technical and regulatory interaction. Forum chairs share information with regulatory agencies to help them merge good scientific and regulatory practices. Outcomes of forum meetings are published in BioProcess International and on the CASSS website (www.casss.org). This process is meant to help ensure that biopharmaceutical products manufactured with advancing technologies in a regulated…

Disposable Components in Biomanufacturing: A Regulatory Perspective

by

On a holistic level, the decision regarding whether to use single-use or stainless steel equipment in a biomanufacturing plant is a significant one. It greatly influences the design, construction, layout, and operation of a plant — and consequently, the timing and cost of the overall project. And regulatory review can add an element of risk to using anything new. Disposables have been viewed as a revolutionary concept, and they are. But from a routine regulatory operational perspective, I believe it…

Bioindustry Researchers Take Strides in Preventing Diseases: Developments in Genetic Diagnosis and Therapy

by

Johnson & Johnson’s pharmaceutical research arm recently launched a drug-development project that will intercept diseases before patients even realize they’re sick. In the company’s words: “The future of healthcare will increasingly depend on identifying and correctly interpreting the earliest signals of disease susceptibility, preventing or intercepting disease before it even begins.†(1). The first targets include Alzheimer’s, some forms of cancer, heart disease, rheumatoid arthritis, multiple sclerosis, and type 1 diabetes. The company’s Disease Interception Accelerator group will search for…

Elucidation: Centers for the Innovation in Advanced Development and Manufacturing

by , , and

The 2009 influenza pandemic was the main driver for the Centers for the Innovation in Advanced Development and Manufacturing (CIADM). As a new federal government authority, the Biomedical Advanced Research and Development Authority (BARDA), directed by Dr. Robin Robinson, assembled a team of scientists and technicians with a vast array of knowledge and experience in chemical, biological, radiation, and nuclear fields. BARDA’s directive was to enhance preparedness for catastrophic challenges such as an influenza pandemic or other serious threats to…

Special Report on Assays, Test Methods, and Comparability The CMC Strategy Forum Series, Part 4, Biosimilar Products: Scientific Principles, Challenges, and Opportunities

by , , and

The Chemistry, Manufacturing, and Controls (CMC) Strategy Forum held on 22 January 2012 in San Francisco, CA, focused on selected scientific and regulatory aspects in the development of biosimilar products. Such products are an increasingly important area of interest for both the biopharmaceutical industry and its regulatory agencies. Biosimilars are highly complex, so scientists have been unable to demonstrate identity to a level typically possible for small molecules. Consequently, specific scientific and regulatory approaches are required to ensure the high…

Special Report on Assays, Test Methods, and Comparability The CMC Strategy Forum Series, Part 4, The Role of Higher-Order Structure in Defining Biopharmaceutical Quality

by , , , and

Cosponsored by CASSS (an International Separation Science Society) and the US FDA, the 17th CMC Strategy Forum was designed to explore the relationships between higher-order molecular structure and quality of therapeutic proteins and peptides, vaccines, and blood-derived products. Understanding those relationships is important to defining and controlling the critical quality attributes (CQAs) of biopharmaceutical products. The forum program highlighted the current state of the art for analytical tools used to monitor higher-order structure. Case studies demonstrating the effects of changes…

Special Report on Assays, Test Methods, and Comparability The CMC Strategy Forum Series, Part 4, Demonstrating Comparability for Well-Characterized Biotechnology Products: Early Phase, Late Phase, and Postapproval

by

Challenges and approaches in demonstrating comparability of a well-characterized biotechnology product after manufacturing changes can be as varied and complex as the products themselves. Participants at the January 2005 CMC Strategy Forum sought to discuss and agree on common implementation strategies for different manufacturing change scenarios (1). Development of flexible, comprehensive approaches in strategy development addressed evaluation of critical product characteristics, appropriate process steps to test, numbers of lots and levels of testing required, and assessment of product comparability. The…
