A recent paper in Expert Opinion on Biological Therapy studies failed fillings for biosimilar drugs.
Over the past three decades, biotherapeutics have revolutionized healthcare by providing effective treatments for complex diseases that were previously challenging to manage with traditional small molecule pharmaceuticals. With the expiration or imminent expiry of patents on several biotherapeutics, the market for biosimilars has witnessed remarkable growth. Biosimilars are products deemed similar to already-approved innovator products in terms of safety and efficacy. However, the production of biosimilars presents unique complexities, as the manufacturing process itself is the product. Small variations in the biotech processes can lead to significant undesirable clinical effects. Consequently, regulatory authorities worldwide have established stringent guidelines to ensure the safe approval of biosimilars.
This article offers a thorough review of unsuccessful regulatory filings for biosimilar approval. Focusing on regulatory submissions to the European Medicines Agency (EMA) and the Food and Drug Administration (FDA) in the United States, the authors identify and discuss key shortcomings in these filings, which resulted in non-approval.
