Which Product Trend is Shaping the Next Phase of Growth in the Antibody Fragments Market?
Bispecific antibody constructs are the primary product trend reshaping this market. These engineered proteins can simultaneously bind two different targets, allowing for, among other things, redirecting immune cells to tumors, dual pathway blockade, and greater therapeutic precision than conventional monoclonal antibodies. The Roche FDA approval of Lunsumio VELO (mosunetuzumab, subcutaneous) in December 2025 showed that bispecific formats can be formulated so patients can self-administer, reducing treatment burden.
The trend is reinforced by the commercial validation of bispecific platforms, with 15 bispecific antibodies now FDA-approved as of 2026. Investors of proprietary bispecific engineering platforms like CrossMab, DuoBody and BiTE technologies are well positioned for continued pipeline value. The switch from IV to subcutaneous preparations is likely to accelerate adoption by reducing the number of hospital visits and costs to healthcare systems.
