The BioPhorum approach to the registration of innovative raw materials using quality by design principles, explored the diversity of registration practices for innovative and complex materials and illustrated this through a survey of the current state. This appendix consists of an introduction to Protein A, the process followed for identifying critical material attributes, and controls and principles for registration that would offer future flexibility of supply.

BioPhorum approach to the registration of innovative raw materials using quality by design (QbD) principles
Jan 2022 | Deliverable, Drug Substance, POI - Drug Substance, Publication, Raw materials, Regulatory
BioPhorum has defined a best practice approach to the registration of innovative and complex raw materials. The approach is based on quality by design(QBD) principles. It is applicable to different families of non-compendial raw materials in the manufacture of biologics. The approach has already been used by BioPhorum member organizations and accepted by national health authorities.
Electronic data exchange: a baseline survey summary
Nov 2021 | EDE/Digitization of the In-Bound Supply Chain, POI - Supply Partner, Publication, Raw materials, Supply Partner
A benchmark survey which sets out to establish the baseline for electronic data exchange across participating members, to understand: How suppliers and biomanufacturers were working with EDE for raw materials across their inbound supply chain, whether they were using the ASTM standard and, if so, its application and value to their company and to provide Insights for improving EDE across the sector. The results cover utilization, prioritization, ASTM E3077-17 standard utilization and the benefits and challenges in implementing it, EDE maturity, benefits and challenges for EDE in the inbound supply chain, EDE accelerator and other conclusions.
Industry proposal for a simplified registration process of complex and innovative raw materials in Europe

This paper is the first in a series considering  real-world scenarios where the EHS companion risk assessment template has been completed.  This assessment focuses on cell expansion operations working with the cell line only in R&D labs to develop procedures and controls; it does not include production operations, such as transfection or viral infections.Â
Raw Materials: Supplier change notifications: change areas and requirements
Jun 2021 | Deliverable, Drug Substance, POI - Drug Substance, Publication, Raw materials, Raw Materials Program, Supply Partner
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.
