Product specifications are only as good as the analytical methods used to define them. We’re experts in developing strategies and supporting assay development, qualification and validation. We’re also highly experienced in the demanding potency assays required for complex biopharmaceutical products.


Failure to adequately demonstrate comparability can be a common reason for regulatory non-acceptance. Our consultants can help design required comparability studies to satisfy regulators’ expectations: for changes to your manufacturing process as you optimize it along the way; for biosimilars requiring high precision; or for products with very high intrinsic variability such as autologous cell therapies.


Helping you stay one step ahead of change


Comparability is a major–and very common–challenge for developers of biopharmaceuticals. Changes to the manufacturing process take place almost invariably during product development. These might be major changes within the manufacturing platform and/or changes to the manufacturer itself. Our experienced professionals will ensure that nothing is left to chance in our assessment of the impact of these variances and their reporting to regulators.
