BioPhorum’s E&L data review: a momentous step towards better testing

Extractable and leachable (E&L) compounds associated with the use of polymeric single-use systems (SUS) are important because they have the potential to directly impact on product and patient safety. The 2014 BioPhorum Extractables Protocol provided a standardized framework to conduct extractables testing and has been widely used by SUS suppliers and end-user biomanufacturers. However, since its implementation, concerns have been raised...

Extractables: A comprehensive review of BioPhorum standardized extractables testing data – a deep dive into similarities, differences and trends across extraction solvents and time points

Extractable and leachable (E&L) compounds associated with the use of polymeric single-use systems (SUS) are of primary concern due to their direct impact on product and patient safety. The 2014 Biophorum extractables protocol provided a standardized framework to conduct E&L testing and has been widely used by SUS suppliers as well as the end-user biomanufacturing companies. Since its implementation, several concerns associated with the testing methods proposed in the protocol have been raised by testing laboratories. A comprehensive review of the data generated using the 2014 BioPhorum extractables protocol was initiated by Biophorum’s Extractables and Leachables workstream to mitigate these concerns.

This document aims to summarize the findings of the data review and make scientific, data-driven recommendations to address specific concerns about extraction solvents and testing timepoints. This review established that certain extraction solvents (5M Sodium Chloride and 1% Polysorbate 80) and timepoints (Time 0) proposed in the testing matrix of the 2014 protocol added limited value to determination of the full extractables profile. Such trends were
observed for organic and elemental extractables alike. Based on these findings, specific recommendations about elimination of these solvents and timepoints are outlined in this document.

Knowledge mapping for the biopharmaceutical industry: A test case in CMC business processes from late-stage development to commercial manufacturing (paper and tool)

The management of knowledge in biopharmaceutical organizations has been recognized as an important challenge over recent years. Defining the pain points and designing successful knowledge management (KM) solutions have proven difficult. To address this challenge, BioPhorum Technology Roadmapping applied a KM best practice methodology to capture a process-based knowledge map for a major business process; this was performed by companies who develop and commercialize new therapies. The resulting assessment of knowledge flows revealed that there are significant challenges to both explicit and tacit knowledge flow across the control strategy and method development / technology transfer processes. Some generalized solutions have been proposed. As part of this work, a detailed spreadsheet tool was developed so that organizations can repeat this work on their business processes to understand their knowledge–flow issues and develop fit-for-purpose solutions.

The knowledge mapping tool is available here. Detailed instructions are available within the tool itself. The data in the sheet reflects that used in the illustrative example documented in the companion paper. The data is intended to be removed and replaced with end users data in support of their own KM efforts.
