The European Medicines Agency (EMA) has published a draft Reflection Paper proposing a streamlined pathway for the approval for certain biosimilar medicinal products (biosimilars) in the EU by reducing the clinical data requirements where justified.

Biosimilars are biological medicinal products that are demonstrated to be highly similar to an already authorised biological medicinal product, known as the reference medicinal product (RMP), with no clinically meaningful differences in terms of quality, safety, or efficacy. Biosimilar marketing authorisation applications are subject to reduced data requirements compared to a full application. However, the applicant must submit a data package from a comparability exercise demonstrating that the purported biosimilar is highly similar to the RMP. Typically, this will require a comparative Clinical Efficacy Study (CES) to confirm the similarity (though this requirement can already be waived in certain circumstances).

In its Reflection Paper, the EMA sets out the prerequisites for more general principles for when requirements for a CES may be waived, and only a limited, targeted clinical data package (based on a comparative pharmacokinetic (PK) trial) will be accepted. Where this approach is adopted, this is likely to reduce the clinical development burdens for biosimilar companies.Continue Reading The European Medicines Agency Proposes Streamlined Pathway for the Approval of Biosimilar Medicinal Products in the EU
