Version 2.0 of the BPOG Extractables Protocol 2.0, defines key end-user requirement specifications for single-use components. Arriving 6 years after the original BPOG protocol, this update is the result of strong engagement between biomanufacturers and suppliers, as well as data-driven decision making.

BioPhorum-aligned suppliers have agreed to make information on their datasets easy to find through a central BioPhorum web portal.  In addition, standardized reporting requirements, templates, and FAQs can also be found as part of the BioPhorum Extractables Ecosystem.

A brief overview of what is new and what has changed with the 2020 update to the Biophorum extractables protocol.  See how Pall and end-users have worked closely together including Pall datasets and experiences to simplify and streamline risk assessments with standardized supplier data.

This document summarizes the outcome of the comprehensive review of suppliers’ extractables datasets generated according to the original BPOG Extractables Protocol (2014). The findings serve as the basis of the current BPOG Extractables Protocol (2020).

This article provides insights as to how Pall implemented the BPOG Extractables Protocol for testing single-use components. Sample preparation strategies, analytical methods and laboratory challenges are discussed in detail.

In this article, we compare the extractables profile of autoclaved polyethersulfone (PES) filters generated using the BPOG and the USP <665> extractables protocols. In addition, we share our findings from testing multiple components per the BPOG protocol.

This paper discusses similarities and differences between classical biopharmaceutical (e.g. mAb) and cell and gene therapy (CGT) manufacturing process from an extractables and leachables (E&L) perspective, and  how extractables data generated from standardized protocols (e.g. BPOG, USP <665> may be applied for CGT products and risk assessment. Regulatory consideration and current challenges are also summarized in the paper.

ASTM Committee E55 on Manufacture of Pharmaceutical Products was formed in 2003.

The Bio-Process Systems Alliance (BPSA) recognized the need for a guide on the integrity assurance of single-use systems and formed a working group from supplier and end-user companies to discuss the topic and recommend best practices

End-user perspective outlining single-use system integrity risk assessment, strategy, and the measure of impact failure has on manufacturing through to product delivery. Also covered are best practices to ensure integrity all along the lifecycle of the process

 In order to propose and action good practices to ensure single-use system integrity, the Bio-Process Systems Alliance (BPSA) identifies a risk-management approach that can help companies address potential risks both in system manufacturing and in end-user processes

Join leading industry experts Charlotte Masy of GSK and Patrick Evrard from Pall Corporation to gain insights and answers in this webinar from BioPharma Asia on integrity Assurance for Single-Use Systems, an End-User’s Perspective.

Guide to Irradiation and Sterilization Validation of Single-Use Bioprocess Systems- BPI, May 2008, 10-22

To ensure continued availability of critical, pre-sterilized bioprocess materials, biomanufacturers, suppliers, and SMEs worked collectively to create a risk assessment and qualification approach for X-ray sterilization of single-use bioprocess equipment. This consensus approach, implements a science-based risk assessment and testing protocol to verify that X-ray sterilization, which is covered by ISO 11137, yields an equivalent impact to bioprocess materials as gamma.

Single-use technology is fast growing in the biopharmaceutical industry.  Often, designing new single-use systems involves a long, iterative process between end-user and supplier to ensure quality, regulatory, and technical requirements are met.  Wouldn’t it be convenient if all these requirements were captured in a toolkit? BioPhorum and BPSA have created new templates aligned with industry standards (i.e. ASTM E3051) which will simplify the single-use design process.

Sterile Filter Validation

더 읽어보기

This article focuses on the re-use of hydrophilic- or hydrophobic-membrane sterilizing-grade filters applied in liquid-sterilizing applications. The author reviews different approaches that may be defined as re-use, discusses factors to consider when deciding whether to re-use sterilizing-grade filters, and provides a case study that highlights potential risks and considerations for process validation in filter re-use applications.

This article focuses on the Quality by Design (QbD) risk-based approach initiative and how the Question based Review (QbR) checklist and Quality Overall Summary (QOS) approach are used to review the validation of a drug process and as a starting point to assess risk, and whether an Abbreviated New Drug Application (ANDA) or New Drug Application (NDA) could help manufacturers to maximize the assurance of sterility of their process and meet the expectations of the regulators.

Here we present data that demonstrates the robustness of Pall’s virus clearance product portfolio, as well as strategies for incorporating QbD into virus safety and guidance to help optimize virus clearance trials for increased patient safety. Data from these studies demonstrates that any virus clearance steps are robust, and adequately represent potential worst-case processing conditions.

Single-use technologies require a shift of responsibility from biomanufacturers to suppliers to enable production of safe and reliable drugs. One of the pre-requisites for efficient supply is to have standardized processes to design and manufacture single-use systems. We have developed a unique design, quality and business tool to drive quality and responsiveness, and to support standardization of single-use technologies.

Dr Hélène Pora will take you through the functionalities of this system and demonstrate what benefits it brings to end users when implementing single-use technologies in a regulated environment.

The BPOG Leachables Working Group has recently published a Best Practice guide for Leachables. It was developed to help biopharmaceutical and vaccines manufacturers to develop science-based, robust, and efficient approaches to handling the risk of leachable compounds that is associated with increasing use of single-use systems in manufacturing processes. The Best Practice guide is composed of three parts:

  • The risk assessment model
  • Leachable study design
  • Analytical methods

This webinar provides insight into the application of the best practices for leachables study design by end users, and will include a case study to highlight the importance of the study design.
