Continued Process Verification (CPV): A guide to integrating continued process verification (CPV) and annual product review (APR)
Jun 2021 | Drug Substance
This paper draws on the experiences of more than 20 biopharmaceutical manufacturing companies in creating CPV reports and integrating them with their APR processes to propose an approach that significantly improves efficiency while still complying with regulations and achieving the business benefits of a robust CPV program
This guidance document identifies the relevant change areas, and for each area, exemplifies the type of changes which the biopharmaceutical industry needs to be informed about. It also lists the required information, in terms of supporting data and documentation, to support notification of changes. This guidance is relevant to all raw materials used to produce biopharmaceutical products, including but not limited to cell culture media, fermentation broth components, column resin, buffers, solvents, and excipients. By highlighting the changes biopharmaceutical industry end-users need to know about and specifying the information required, the intention of this industry-aligned guidance is to reduce the quantity of rework required and the time taken to process change requests. In turn, this will reduce variability in demand patterns as end-users refrain from building extensive inventories to mitigate against the perceived risks which arise from proposed changes. While complete alignment and standardization on the information which should be provided for changes is not possible, a more robust alignment on the typical information required, as set on in this guidance, will significantly improve the current state.
The purpose of this best practice guide is to provide key information and best practices for media supplier partners and companies in the biopharmaceutical industry on the design, development and controls for manufacturing of media and medium solutions to minimize potential variation that may impact product quality, process performance and operational efficiency and costs. It is intended that it can be used to support a proactive approach to evaluation and self-audit of internal processes.
Drawing on their real-world experiences, a group of experts drawn from 28 BioPhorum member companies has provided guidance on the detailed working methods that support a successful remote inspection or audit; for example, how to manage information flows between the inspectors and the site subject matter experts’ team. With the impact of Covid-19 likely to be seen for the foreseeable future, virtual inspections may be required for some time. This guidance will help all stakeholders prepare and to avoid the potential problems of remote inspections and audits.

This paper discusses a systematic approach to assessing virus segregation measures, which can help biopharmaceutical developers achieve sufficient segregation for the low-pH inactivation steps in their downstream processes. It covers a process description, mathematical modeling, failure modes and the effects on viral clearance, and the importance of proper design.
Post-Approval Strategies: Risk-based approach for analytical comparability and comparability protocols
Nov 2020 | Drug Substance
Chemistry, manufacturing, and control post approval changes are an intrinsic part of the life cycle of pharmaceutical products. In this paper, the authors examined the potential impact of such changes on the product quality, safety, and efficacy of biologics. Comparability studies and more specifically analytical comparability are introduced as one of the tools that can support both biomanufacturers and health agencies in ensuring that patient safety and product safety and efficacy is maintained through the proposed changes. Together with a scientific risk-based review approach based on product and process knowledge and the definition of acceptance criteria that will ensure that the product is “essentially similar”, what constitutes a holistic comparability study is detailed. ICH Guidelines principles and definitions are used throughout the paper to aid the reader with other appropriate references. Finally, two case studies are presented: change to the manufacturing facility of the drug substance, and change to the manufacturing process of a drug substance intermediate and manufacturing facility.
This toolkit gives users a set of tools to respond to problems and materials to include in their communications and operator training.It will help reduce product losses, investigations, manufacturing disruptions and the number of leaks. It equips industry with tools to help standardize the vocabulary around SUS anatomy and processes and expand its understanding of SUS abnormalities.

The Human Performance Workstream recognized the importance of effective investigation techniques during their collaborative work in 2016. The team conducted a survey of member companies and shared within the workstream a report with 14 recommendations, and 11 best practice company case studies. These recommendations and case studies were used to create an investigator training package for the industry, and to inform the contents of the human performance
assessment tool, which the group uses to benchmark and improve human performance.
It is important for biomanufacturers to understand trace element variation within soy hydrolysates (by knowing the minimum, maximum and average concentrations), so they can determine if the degree of variation has an impact on their process. The knowledge gained through process characterization across the maximum variation found in soy hydrolysates can be evaluated to determine if it has an impact on the biomanufacturers’ process or product on a product-byproduct basis.
This is the first in a series of proposed hydrolysate white papers. The purpose is to educate users of hydrolysates of the various characteristics that they should be aware of to manage their processes. There are many parameters to consider within a hydrolysate. The intention is to start with data that can be collected on as many different hydrolysates used in the biopharmaceutical industry.
