September 20 – 21, 2021 Virtual Public Workshop
Duke-Margolis is collaborating with the U.S. Food and Drug Administration (FDA) to host a two-day virtual public workshop entitled “Pharmacodynamic Biomarkers for Biosimilar Development and Approval” on September 20 – 21, 2021. This virtual public workshop is a forum for regulators, biopharmaceutical developers and academic researchers to discuss the current and future role of pharmacodynamic (PD) biomarkers in improving the efficiency of biosimilar product development and approval.
Biologic medicines play an important role in the treatment of many serious illnesses; however, biologic medicines can be costly. With biosimilars (biologic medicines that are highly similar to and have no clinically meaningful differences from existing FDA‐approved reference products), drug developers can leverage the safety and effectiveness data of reference products to support the approval of biosimilars, potentially providing access to lower cost treatments.
Comparative clinical efficacy study(ies) may not be needed to establish biosimilarity between investigational biosimilars and their reference products if there are sufficient data from other comparative studies including human pharmacokinetic (PK) and PD studies [1,2]. When available, PD biomarkers can demonstrate the characteristics of a biosimilar’s target effects, helping reduce residual uncertainty about whether there are no clinically meaningful differences between a biosimilar and its reference product.
However, few biosimilars have been approved that leverage PD biomarker data without comparative clinical efficacy studies. Although the FDA has published guidance on PD biomarker selection and general study design considerations , additional regulatory clarity on the use of PD biomarkers to support demonstrations of biosimilarity might facilitate additional biosimilar development and approval. Therefore, the FDA is working to advance an evidentiary framework and methodology for identifying, characterizing, and applying PD biomarkers to assess biosimilarity so patients can access safe, effective, and lower cost biosimilars sooner.
- Discuss the current and potential future state of leveraging PD biomarkers for biosimilar development and approval
- Summarize FDA’s initiatives to advance biosimilar development
- Describe stakeholders’ experience with PD biomarkers in biosimilar development
- Explain research efforts to promote a broader application of PD biomarkers in biosimilar development
