The feature story in this issue centers on the challenges and developments around raw material control for biological products. A main focus is the discussion that took place at a USP workshop on the raw material issues held in April 2021. The story’s three parts delve into: ● FDA views on where the regulatory concerns and expectations lie across the review and inspection continuum ● how the challenges expand in handling raw materials in the CGT context, and ● where biomanufacturers are in using and controlling polysorbates, in particular.
