Biosimilar
We have supported more than 35 biosimilar programs destined for regulatory submission
Bringing a biosimilar to market requires extensive experience, broad technical capabilities and a deep understanding of the regulatory pathway. We understand the unique needs of a biosimilar drug relative to other biopharmaceutical compounds:
- Biosimilars must demonstrate comparable results (safety, purity, potency, stability and immunogenicity) to the innovator product and across product lots
- Due to the physicochemical attributes and functional activity of the biosimilar, assays developed for the innovator product may require adjustments and/or redevelopment and validation
- Biologics by nature are more variable than small molecules, making the analytical methods subject to variation across instruments, critical reagents, operators and even day-to-day and lab-to-lab differences
- Biosimilar development is complex and each project has specific needs
- Bioequivalence (BE) studies, anti-drug antibody (ADA) testing, and efficacy evaluations are crucial to explain changes from the innovator drug. Disease states and manufacturing changes can impact pharmacokinetic (PK) and ADA assessments. Manufacturing changes introduced between studies for scale-up or patent reasons can also have an effect on those assessments.
In addition to bioequivalence (BE) studies, anti-drug antibody (ADA) safety and efficacy testing are critical to the development of biosimilar to explain and justify changes from the innovator drug. Disease states can also affect pharmacokinetic (PK) and ADA assessments (even in Phase I studies). Manufacturing changes introduced between studies for scale-up or patent reasons can also have an effect on those assessments.
Competition in the biosimilar arena breeds extremely tight timelines. With our propriety method development and validation, regulatory expertise, and automation-driven efficiencies, we streamline the path to approval with high-quality testing that supports every stage of biosimilar development to accelerate time to market.
Our bioanalytical lab has supported more than 35 biosimilar programs in support of U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) submissions. We also have experience working with 17 of the top 20 and all of the top 10 Biosimilars in 2024.
