Biosimilar Antibodies in Drug Discovery
In drug discovery and subsequent development phases, biosimilar antibodies like Infliximab can be used as benchmarks in several ways:
- Analytical Methods and Characterization: Molecular structure, post-translational modifications (PTMs), binding-specifities, and other attributes of approved biologicals are well-characterized due to their history as a reference biologic. Analytical methods and characterization techniques for new biosimilars or alternative therapy approaches can be benchmarked against those used for existing biosimilars to ensure accurate assessment of similarity.
- Pharmacokinetics: Biosimilars can provide a reference point for comparing the pharmacokinetic properties of a biosimilar to those of the reference product. Pharmacokinetics refers to the study of how a drug is absorbed, distributed, metabolized, and eliminated by the body.
- Immunogenicity Assessment: Immunogenicity profiles, or the likelihood of triggering an immune response, are known from clinical experience for biosimilars that have already been introduced to the market. When developing a biosimilar or an alternative therapeutic approach, companies benchmark their immunogenicity assessment strategies against those used for existing biosimilars to ensure appropriate evaluation of potential immune reactions.
- Clinical Trial Design: Clinical trials for biosimilar development often include a comparative efficacy and safety study, where the biosimilar is compared to the established reference product (e.g. Trastuzumab). The clinical trial design, endpoints, patient populations, and statistical analyses are often compared to existing trials of the reference product.
- Regulatory Approval Pathways: Regulatory authorities, such as the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA), use approved biosimilars (e.g. Ranibizumab) as a reference when establishing guidelines and requirements for biosimilar approval. Developers of biosimilars can adapt their development processes and compare their data against the regulatory expectations set for existing biosimilars.
Overall, biosimilars that are already in the clinic have a well-established history, clinical data, and regulatory status that make them valuable benchmarks in drug discovery to demonstrate the similarity, safety, and effectiveness of new drug candidates. Established and well studied biosimilars serve as gold standard when establishing new biological drugs and treatments. antibodies-online.com offers a very broad range of biosimilars and a great product range to choose from.
