Biosimilar Stable Cell Lines

The biosimilars are drugs that are highly similar but not identical to the biological reference. Their development and evaluation procedures are different from those of chemical generics. At Creative Biolabs, we focus on the challenges and opportunities of biosimilars and are committed to assisting clients in providing drug discovery, screening, optimization, and characterization profiling services. Increasingly, biosimilars are expected to reduce medical costs and offer more treatment options for patients worldwide.

The biologic is a complex molecule in the living system. Its development involves multiple degrees of intricate, highly controlled manufacturing processes, combined with preclinical structural, biological, and functional assessments, as well as clinical safety and efficacy. Furthermore, to ensure a high level of similarity, a biosimilar undergoes a comparability exercise at every step of the development, testifying that potential differences from the reference are not clinically meaningful with regard to safety, purity, and potency [U.S. Food and Drug Administration (FDA)] or quality, safety, and efficacy [European Medicines Agency (EMA)]. Finally, clinical pharmacokinetic/pharmacodynamic (PK/PD), together with clinical efficacy/safety similarity, must be confirmed between biosimilar and originator. The regulators of FDA and the EMA will consider the totality of evidence from this comprehensive step-wise comparative similarity data in its determination of biosimilarity for licensing.

Biosimilars Development Guidelines

The commercial biosimilars, such as rituximab, trastuzumab, and bevacizumab, are being used to optimize the clinically therapeutic strategies in medical oncology. A number of rigorous regulated processes required to develop a biosimilar have been designed to establish a high biosimilarity with a reference product in terms of structural, functional, biological, and clinical attributes. Based on the originator characterization, we can offer corresponding biosimilar developments from start to finish, from initial property to stability studies to determine a desirable biosimilar. In collaboration with our GMP partners, there would be the best versatile course of action for clients proposed biosimilar sooner.

With the expiration of biological drug patents, biosimilars emerge and promise to be an attractive opportunity for physicians, patients, and healthcare organizations by offering greater choice and a more cost-effective alternative. Unlike biologics, the development of a biosimilar largely emphasizes nonclinical (physicochemical, biologic, and animal) aspects. At Creative Biolabs, our step-by-step approach for biosimilar development services could help clients move smoothly from product characterization and biosafety testing to comparability studies and clinical trials. If you have any interests, please contact us for more information.
