Supplier change notifications – bringing color to a grey area

Regulators require the biopharmaceutical industry to manage changes to raw materials in a compliant way – including those initiated by suppliers. A significant challenge is how to manage the large volume of supplier change notifications (SCNs) while ensuring a compliant and uninterrupted supply of materials for production. Companies often need to manage hundreds of raw material SCNs per year, potentially covering hundreds of materials from a...

Raw Materials: Supplier change notifications: change areas and requirements

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.

Bringing clarity to trace element variations of hydrolysates

Protein hydrolysates are an essential component in cell culture medium formulation during the manufacture of protein therapeutics. However, as they may be derived from microbial, plant or animal sources, variations in their composition are unavoidable. This poses a potential risk to biomanufacturing as cell lines and products may be sensitive to slight variations in the hydrolysate composition, which may have an impact on process performance...

Raw Materials: Trace element variation of soy hydrolysate used in biopharmaceutical manufacturing

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.

China: Registration of raw materials entering the composition or presentation of biopharmaceuticals

Since 2017, it has been mandatory for suppliers of APIs, excipients and packaging materials to register their material in China on the DMF registration platform. While many agencies ask for details of a component’s quality and its impact on products, the Chinese requirements for ‘high risk’ materials, such as those used in biopharmaceuticals, also ask for historical information that is typically proprietary which many suppliers are reluctant to share. This paper summarizes the requirements for raw materials in other ICH countries and compares these to the Chinese approach. The paper also lists all of the details needed for the Chinese registration of biopharmaceutical products’ raw materials in a single place, to help suppliers register their products into this vast market.
