Glycoengineered Antibodies and Fc Protein – Virtue of enhanced effector functions

With close to 100 approved monoclonal antibodies, and over 550 molecules in the clinical pipeline, antibody based pharmacological interventions have become one of the fast growing segment of the biopharmaceutical industry.[1] In fact, these interventions are anticipated to generate a cumulative sales of USD 300 billion by 2025.[2] Further, within the antibody therapeutics industry, engineered antibodies, developed by modifying the fragment crystallizable (Fc) region, have garnered significant interest over the past few years. The modifications (such as Glycoengineered Antibodies, protein engineering or isotype chimerism) in the Fc region of an antibody have shown to augment the various effector functions, such as antibody-dependent cellular cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC), antibody-dependent cellular phagocytosis (ADCP) activity and / or the half-life of the molecule. Moreover, several Fc engineering technologies enable the suppression of the effector functions in certain pathways, and are being actively exploited for development of anti-cancer antibodies.

Over time, a substantial body of evidence has validated the therapeutic applications of Fc engineering platforms, which, in turn, has led to the establishment of numerous strategic partnerships (focused on therapy development and clinical research) and significant investment into the innovator companies. The consistent research efforts in this domain have translated into the emergence of two blockbuster drugs, namely Gazyva (for Chronic Lymphocytic Leukemia) and POTELEGIO (for Sézary syndrome) and several other Fc engineered antibody products, including Margenza, MONJUVI and SKYRIZI that received approval in the past few years. More recently, in 2021, two Fc engineered antibodies, namely Sotrovimab and Etesevimab, got approved for the treatment of COVID-19. Further, there are several drugs in the development pipeline, which are being investigated by various small and established pharmaceutical companies. The promising clinical results, and ongoing technical developments, coupled to the growing interest of biopharmaceutical developers, are anticipated to give the required impetus to the push pipeline products to higher stages of development, and commercialization. We believe that the market is likely to evolve at a commendable pace over the next decade.
