Concept
Join Us!
As the biosimilar market continues to expand, developers face increasing pressure to generate robust analytical and biosafety data while accelerating timelines to IND and BLA submissions. Selecting the right testing partner can be critical to reducing development risk, meeting regulatory expectations, and avoiding costly delays.
Join experts from Sartorius to explore how outsourced analytical characterization and GMP testing can support successful biosimilar development from early characterization through commercial manufacturing.
This webinar will highlight the importance of comprehensive biosimilarity assessment, how cell bank manufacturing and testing provide the foundation for compliant biologics production and the critical role of bulk harvest testing in ensuring batch safety and process control.Attendees will learn how Sartorius' extensive experience supporting more than 800 clients, contributing to approximately 50 regulatory submissions, and providing direct access to scientific and regulatory experts can help accelerate development timelines while maintaining quality and regulatory confidence. Through a collaborative partnership approach, we work closely with clients to navigate complex testing requirements and support successful progression toward regulatory milestones and commercialization.
