Types within the Monoclonal Antibody Biologics and Biosimilars market are categorized into monoclonal antibodies (mAbs) and biosimilars, each with distinct subtypes. mAbs are classified by isotype (e.g., IgG1, IgG4), mechanism of action (e.g., agonist, antagonist), and target (e.g., cytokines, receptors). Biosimilars, subject to regulatory equivalence frameworks, are further segmented by therapeutic area (oncology, rheumatology) and molecular structure (full-length, Fc fragments). mAbs dominate the market due to their innovation and patent protection, while biosimilars exhibit rapid growth in mature markets, reducing cost barriers. Key subtypes under biosimilars include follow-on biologics and interchangeable biosimilars, with the latter gaining regulatory traction in the U.S. This taxonomy highlights the marketโs transition from innovation-driven mAbs to cost-focused biosimilars, influencing investment priorities and competitive dynamics.
