Segmentation by types highlights monoclonal antibodies as the largest category at 60% of the market, owing to their targeted efficacy and established regulatory pathways. Bispecific antibodies, at 20%, are rising due to their dual-targeting capacity in oncology and autoimmune therapies. Polyclonal antibodies, though limited to 10%, persist in niche diagnostic and research applications. Engineering advancements, such as antibody-drug conjugates (ADCs) and engineered T-cell therapies, contribute the remaining 10%, reflecting technological diversification. This Therapeutic Antibodies Drug taxonomy illustrates the balance between conventional platforms and innovators driving next-generation therapies, with mAbs maintaining dominance while newer formats gain traction in specialized indications.
