Biosimilars Development: Demonstrating Biosimilarity

A biosimilar is a biological product that is highly similar to a reference biological product notwithstanding minor differences in clinically inactive components, and for which there are no clinically meaningful differences between the biological product and the reference product in terms of the safety, purity, and potency of the product. Biosimilars are not to be confused with generic chemical medicines, which use identical active ingredients. It is critical to demonstrate the comparability of a biosimilar to its originator product not only to ensure safety and efficacy but also to allow for drug substitution and exchangeability.

The Biosimilars Council reports that by 2020, brand biologic medicines worth an estimated $81 billion in global annual sales will lose their patents. This provides a significant opportunity for the development of lower cost biosimilar alternatives, and the biosimilars market is expected to expand more than 20-fold in the next 5 years.

Leverage BioAgilytix’s Expertise To Progress Your Biosimilar Development Efforts

The surge of upcoming patent expiries has driven demand for biosimilars – but without access to the originator’s molecular clone and cell bank, the exact fermentation and purification process, or the active drug substance, mimicking the performance of the branded original is extremely complex. Averaging over 15 years of bench experience, our veteran team of BPMs have world-leading expertise in biosimilars development, and will apply that knowledge to optimally support your project. We are able to offer services under GLP, GMP, and GCP to meet your distinct regulatory requirements.

The rise of biosimilars brings with it the promise of broader patient access to important medicines for serious diseases. BioAgilytix is committed to supporting this area of innovation by bringing together the best science, technologies, and processes needed to develop and deliver reliable, high-quality biosimilars for a wide range of disease states. Let our specialized scientists help you identify the optimal method and platform for your pharmacokinetic assay needs today.
