The Evolution of Biologics and Biosimilars

Updated: Jan 26



Biopharmaceuticals have seen significant advances in recent years, particularly with the development of biologics and biosimilars. These innovative therapies have revolutionised the treatment landscape for various diseases, offering targeted and personalised approaches.


Currently, 80% of the top-selling pharmaceuticals are biologics and, as the demand for these therapies continues to rise, the development of biosimilars has had a significant positive impact on costs for clinical trials, helping to bring safe and effective drugs to market at an affordable price.


Understanding Biologics and Biosimilars


Biologics are therapeutic agents derived from living organisms such as humans, animals or microorganisms. They are large, complex molecules that include proteins, antibodies and nucleic acids.


Biologics are the new standard of care and have opened new avenues for the treatment of conditions such as cancer, auto-immune disorders and genetic diseases, offering enhanced efficacy and reduced side-effects in comparison to traditional small molecule drugs.


Biologics are protected by patents, which grant exclusive rights to the originator company for a specific period. This exclusivity allows the originator company to charge premium prices for their products, which has a significant impact on the cost of clinical trials. However, when patents expire, biosimilar manufacturers can enter the market, leading to increased competition and potential price reductions for clinical trials.


Biosimilars are highly similar versions of approved biologics (referred to as ‘reference medicines’ or ‘originator medicines’) and are designed to be comparable in terms of structure, quality, safety and efficacy. These follow-on versions offer an opportunity to provide more affordable alternatives to costly biologics, expanding patient access to life-changing therapies.
