The implementation of single-use technologies for pharmaceutical product development continues to gain momentum; this trend is due to the advantages of increased flexibility, speed of implementation and lower capital investment. In particular, they are seen as a means to accelerate the production of material for clinical trials. However, a primary concern regarding the use of such technologies is the impact and level of leachables in the final drug substance. Typically this concern is addressed through a risk assessment utilizing extractable…

Current trends in the bioprocessing industry are driving mAb and plasma producers to formulate at higher protein concentrations. As a result, formulating using tangential flow filtration (TFF) may be limited in reaching these concentrations due to high pressures caused by highly viscous feed streams. Filtration devices used during processing have to be optimized in order to handle both high viscosity and pressures while maintaining high flux and excellent product recovery. In this study, a family of filtration devices was evaluated…
