Genetically Engineered Multivalent Proteins for Targeted Immunotherapy

mAbs initiated the unprecedented breakthroughs in cancer immunotherapy and are rapidly evolving with multiple therapeutic platforms. One next-generation strategy engineers multivalent proteins that ligate single-chain variable fragments targeting cellular effectors, tumor-associated antigens, and cytokines. These developing therapeutics target and regulate cellular effector bioactivity and significantly improve clinical outcomes. (C) 2016 AACR.
