Abstract
Activatable binding polypeptides (ABPs), which contain a target binding moiety (TBM), a masking moiety (MM), and a cleavable moiety (CM) are provided. Activatable antibody compositions, which contain a TBM containing an antigen binding domain (ABD), a MM and a CM are provided. Furthermore, ABPs which contain a first TBM, a second TBM and a CM are provided. The ABPs exhibit an 'activatable' conformation such that at least one of the TBMs is less accessible to target when uncleaved than after cleavage of the CM in the presence of a cleaving agent capable of cleaving the CM. Further provided are libraries of candidate ABPs, methods of screening to identify such ABPs, and methods of use. Further provided are ABPs having TBMs that bind VEGF, CTLA-4, or VCAM, ABPs having a first TBM that binds VEGF and a second TBM that binds FGF, as well as compositions and methods of use.
