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.

To gain a better understanding of current industry approaches for establishing biopharmaceutical drug product (DP) robustness, the BPDG-Formulation Workstream conducted an intercompany collaboration exercise, which included a benchmarking survey and extensive group discussions around the scope, design, and execution of robustness studies. The results of this industry collaboration revealed several key common themes: (1) overall DP robustness is defined by both the formulation and the manufacturing process robustness; (2) robustness integrates the principles of quality by design (QbD); (3) DP robustness is an important factor in setting critical quality attribute control strategies and commercial specifications; (4) most companies employ robustness studies, along with prior knowledge, risk assessments, and statistics, to develop the DP design space; (5) studies are tailored to commercial development needs and the practices of each company. Three case studies further illustrate how a robustness study design for a biopharmaceutical DP balances experimental complexity, statistical power, scientific understanding, and risk assessment to provide the desired product and process knowledge. The team discusses identified industry challenges with regard to biopharmaceutical DP robustness and presents some recommendations for best practices.
