First 2022 GaBI Journal issue highlights

The first GaBI Journal issue of 2022 comes at a time of both hope and despair. While the COVID-19 pandemic continues to cause significant global morbidity and mortality; especially in resource-poor countries, both the pace and direction of changes are beginning to produce some encouraging signs. Positive trends are in part the result of the…

Structural characterization methods for biosimilars: fit-for-purpose, qualified or validated

Abstract: Detailed and accurate structural characterization of biopharmaceuticals is of paramount importance for product definition, assessment of impurities and achieving in-depth understanding of manufacturing processes. But how can we have confidence in the data obtained from characterization studies? The expectation from regulatory authorities when assessing methods for product characterization is that there will be some…
