  • Publication number: 20200385469
    Abstract: The present invention relates to activatable recombinant polypeptide compositions comprising a cleavage release segment. In some instances, the activatable recombinant polypeptide compositions include an XTEN linked to binding moieties by cleavable release segments that, when cleaved, the binding moieties are capable of binding together effector T cells with targeted tumor or cancer cells and effecting cytolysis of the tumor cells or cancer cells. The invention also provides compositions and methods of making and using the cleavable activatable recombinant compositions.

  • Publication number: 20190153115
    Abstract: The present invention relates to bispecific chimeric polypeptide assembly compositions comprising bulking moieties linked to binding domains by cleavable release segments that, when cleaved are capable of concurrently binding effector T cells with targeted tumor or cancer cells and effecting cytolysis of the tumor cells or cancer cells. The invention also provides compositions and methods of making and using the cleavable chimeric polypeptide assembly compositions.
