Biologics or biological drug products are medicinal preparations made from living organisms or containing components of living organisms. They are complex molecules manufactured through biological processes in living organisms like plants, animals or microorganisms. These include proteins, nucleic acids, live microbial therapies and whole cells. Some key examples of biologics include monoclonal antibodies, recombinant proteins, and gene therapy drugs.
Coherent Market Insights explores in Biologics Market how with continued research and development, biologics hold tremendous promise to improve patients’ lives.
History of Biologics
The history of biologics can be traced back to early 1900s when insulin was one of the first few biological drugs to be used for diabetes treatment. It was extracted from animal pancreases. Since then biotechnology has advanced significantly and modern methods are now used for developing and producing biologics. Some key historical developments include production of human insulin through recombinant DNA technology in 1978, development of monoclonal antibody technology enabling custom antibodies to be produced in the 1980s and first FDA approval of gene therapy drug in 2017. Today many biologics are available for treating cancer, autoimmune diseases, hematologic diseases and others.
Mechanism of Action
Biologics have very complex structures and functions thus act through intricate mechanisms in the body. Their mechanisms are often highly specific and targeted. Some common mechanisms involve:
– Stimulating or suppressing immune system responses – Many biologics work by enhancing or reducing certain immune responses in the body which helps in treating conditions caused due to abnormal immunity. Examples are monoclonal antibodies and cytokines.
– Replacing deficient molecules –Biologics Market developed through recombinant DNA technology help replace molecules missing or deficient in the body. Insulin is a perfect example which replaces insulin in diabetes patients.
– Gene therapy – These biologics are used to introduce functional genes inside patients’ cells to compensate for abnormal genes causing disorders. They help manage genetic conditions.
Manufacturing of Biologics
Manufacturing biologics is a long, complex and highly regulated process as even minor changes can impact their efficacy and safety significantly:
– Cell culture – Production involves growing specific cell lines like mammalian, bacterial, yeast or plant cells and harvesting biomolecules secreted by them.
– Purification – Raw material undergoes series of purification techniques like filtration, chromatography to isolate final drug substance. Even small contaminants need to be removed thoroughly.
– Testing and characterization – At each step, extensive testing and analysis is done to ensure quality, purity, potency and consistency as per regulatory standards.
– Formulation – Purified drug is formulated into final drug product like lyophilized powder, solution etc with excipients.
– Filling and finishing – Product gets filled into containers, labeled and packaged under strict quality control.
– Quality assurance – Manufacturing is validated at each stage and final product release is only after meeting all quality specifications.
Regulations are stringent to ensure identity, strength, quality, purity and safety of complex biologic molecules. Even minutest changes in process can impact product and require re-evaluation.
Applications of Biologics
With improved biotechnology techniques, use of biologics has increased tremendously over last few decades. Some key therapeutic areas where biologics are playing a major role include:
- Cancer – Biologics form a key part of modern cancer management. Monoclonal antibody drugs aid in delivery of targeted therapy. Examples are Rituximab, Trastuzumab, Pembrolizumab.
- Autoimmune diseases – Conditions like rheumatoid arthritis, inflammatory bowel disease are commonly treated with biologic disease-modifying anti-rheumatic drugs and monoclonal antibodies which regulate overactive immunity.
- Hematology – Recombinant versions of blood factors and biologic therapies help manage hemophilia, anemia and blood cancers. Erythropoietin, Filgrastim are examples.
- Dermatology – Biologics targeting specific cytokines and pathways have revolutionized treatment of chronic skin conditions like psoriasis.
- Ophthalmology – Anti-VEGF biologics are primary therapy for retinal vascular disorders like wet age-related macular degeneration.
Other areas include endocrinology, organ transplant, neurology etc. Development of newer mechanisms will further expand biologics applications.
The global biologics market is growing steadily with increasing use across multiple therapy areas. As per the report published by (2022), the market accounted for annual sales of over US$ 260 billion in 2020 and is projected to reach around US$ 500 billion by 2028 growing at 8.2% CAGR during forecast period. North America currently dominates the market share attributed to factors like rising biosimilar approvals, healthcare infrastructure and high adoption of cutting-edge biologic drugs. Asia Pacific region is expected to show fastest growth due to large population base, growing per capita income, expanding insurance coverage and increasing lifestyle diseases. Advancements in biosimilar technologies, focus on precision and personalized medicine using biologics, collaborations for developing novel mechanisms will provide opportunities for sustainable growth of biologics market in coming years.
