Bispecific antibodies (BsAb) that engage multiple pathways are a promising therapeutic strategy to improve and prolong the efficacy of biologics in complex diseases. In the early stages of discovery, BsAbs often exhibit a broad range of pharmacokinetic (PK) behavior. Optimization of the neonatal Fc receptor (FcRn) interactions and removal of undesi...

... 5,6 The slow clinical success of BsAbs can be attributed to several factors, including increased structural complexity leading to greater challenges in their CMC properties, and in their pharmacokinetic (PK) profiles. 7,8 PK of mAbs is characterized by a slow systemic clearance and a long terminal elimination half-life, which is primarily governed by their ability to bind to and recycle through the neonatal Fc receptor (FcRn)-mediated recycling pathway. 9 The FcRn-mediated recycling mechanism involves the nonspecific pinocytosis of IgG and albumin into cells, their binding to FcRn in acidic endosomes, and their subsequent recycling back to the cell surface at neutral pH. ...
