Host Cell Protein Analysis in Biologic Drug Development

January 26, 2019

Host cell proteins (HCPs) are common impurities in biologic drug products and are an obligatory critical quality attribute (CQA). The individual protein contaminants that make up the HCP profile, however, may vary significantly among individual biologic products and expression systems. As such, the HCP profile must be analyzed to identify even low levels of potentially concerning species in a biologic drug to ensure safety and efficacy. This whitepaper reviews fundamental aspects of HCPs pertaining to biologic drug development and current and emerging approaches to HCP analysis.

Healthcare system readiness for the adoption of advanced therapies: learnings from the introduction of CAR T cell therapies in the UK

whitePaper | September 17, 2021

The adoption of CAR T therapies in the UK NHS is a success story, especially seen in relation to the experience in many other countries. The UK NHS showed itself to be agile, and responsive to addressing the unique challenges these therapies present, which facilitated access to patients earlier than in many other countries. (including delivery centre selection, development of service specifications, collaboration with manufacturers throughout the preparation phase for adoption, establishment of national multidisciplinary CAR T team to ensure equity of access and prioritization of resources (where needed)).
