  • Publication number: 20210107999
    Abstract: Provided herein are methods of treating eye disorders by administering an anti-VEGF antibody and/or conjugate to a subject having an eye disorder. The anti-VEGF antibody of the present disclosure may be an anti-VEGF antibody conjugate that includes a polymeric moiety that extends the half-life/effectiveness/properties of the antibody when administered to a subject. A method of the present disclosure includes administering one or more doses of an anti-VEGF antibody conjugate to a subject (e.g., human or other mammalian patient) in need of treating an eye disorder, where the anti-VEGF antibody conjugate may be administered less frequently than a standard anti-VEGF therapy to treat the eye disorder.

  • Publication number: 20200262905
    Abstract: The invention provides a dual VEGF/PDGF antagonist comprising a VEGF antagonist linked to a PDGF antagonist. The VEGF antagonist is an antibody to a VEGF or VEGFR or is a VEGFR extracellular trap segment (i.e., a segment from the extracellular region of one or more VEGFR receptors that inhibits binding of at least one VEGFR to at least one VEGF). The PDGF antagonist is an antibody to a PDGF or PDGFR or is a PDGFR extracellular trap segment (i.e., segment from the extracellular region of one or more PDGFRs, which inhibits binding of at least one PDGFR and at least one PDGF). The dual antagonist is preferably conjugated to a half-life extending moiety, such as a HEMA-PC polymer. The dual antagonist is particularly useful for treating wet aged related macular degeneration.
