Plan Comparative Stability Studies for Biosimilars vs. Reference Product

Understanding the Tip: Why comparative stability matters for biosimilars: Biosimilars must establish similarity not only in terms of structure, function, and clinical performance but also in stability behavior. Comparative stability studies help demonstrate that the biosimilar and its reference product degrade in a similar manner under identical conditions. This supports the claim of “no clinically…

How to Justify Study Continuation After Significant Deviations

In the pharmaceutical industry, deviations during stability studies can challenge the integrity of your data and call into question the continuation of the study. Regulatory authorities such as the USFDA expect firms to assess whether the deviation significantly impacts product quality or study reliability. This guide outlines a structured, risk-based approach to justify the continuation…

Understanding the Role of Storage Excursions on Shelf Life Projections

In pharmaceutical manufacturing and distribution, maintaining the integrity of storage conditions is paramount to ensuring drug product quality. However, storage excursions—temporary deviations from prescribed temperature or humidity ranges—can and do occur. Whether during transportation, warehousing, or local storage, these excursions may impact the chemical and physical stability of drug products. This tutorial explores how such…
