  • Publication number: 20240018219
    Abstract: The disclosure provides anti-DENV antibodies and methods of making and using the same. Nucleic acids encoding the anti-DENV antibodies and host cells comprising the nucleic acids are also provided. The anti-DENV antibodies have uses that include treating DENV infection. The disclosure also provided polypeptides containing a variant Fc region and methods of making and using the same. Nucleic acids encoding the polypeptides and host cells comprising the nucleic acids are also provided. The polypeptides have uses that include treating a viral infection. Also claimed is a polypeptide comprising a Fc variant comprising at least one amino acid alteration in a parent Fc region, wherein the variant Fc region has a substantially decreased FcYR-binding activity and does not have a substantially decreased C1 q-binding activity when compared to the parent Fc region.

  • Publication number: 20220204605
    Abstract: The objective of the invention is to provide cross-species anti-latent TGF-beta 1 antibodies which inhibit a protease mediated activation of latent TGF-beta 1 without inhibiting integrin mediated activation of latent TGF-beta 1. To obtain the anti-latent TGF-beta 1 antibodies of the invention, anti-latent-latent TGF-beta 1 antibodies which inhibit a protease mediated activation of latent TGF-beta 1 without inhibiting integrin mediated activation of latent TGF-beta 1 were screened, and then humanized, and further optimized. The invention also provides combination therapies comprising an anti-latent TGF-beta 1 antibody and one or more immune checkpoint inhibitors, preferably a PD-1 axis binding antagonists.
