Controlling Residual Host Cell Proteins (HCP) Impurities in Biopharmaceuticals

Biotherapeutics must be free of Bioprocess-related impurities, including protein contaminants derived from the Host Cell used as the expression system (bacterium, yeast, mammalian, insect or plant cells). HCP fit the definition of the Critical Quality Attribute (CQA) due to their potential to affect product safety (immunogenicity risk for patients) and efficacy. Regulatory guidelines therefore require manufacturers to monitor the removal of HCP impurities in order to manage these risks.

The challenges HCP pose is reflected in the growing number of publications and scientific conferences devoted to these impurities. The complexity of HCP analysis arises from their heterogeneity. Biopharma companies are therefore advised to manage this risk right from the early phases of the candidate biopharmaceuticals lifecycle development, and to generate a sufficient knowledge to demonstrate control before submitting regulatory filing.
