  • Patent number: 11660352
    Abstract: Antibodies that bind specifically to glycosylated PD-L1 relative to unglycosylated PD-L1, block binding of PD-L1 to PD-1 and promote internalization and degradation of PD-L1 are provided. Antibodies that recognize specific epitopes on glycosylated PD-L1 protein and that exhibit the dual functions of both blocking the binding of PD-L1 to PD-1 and also facilitating the internalization of PD-L1 on cells are provided. In some aspects, PD-L1 polypeptides comprising glycosylated amino acid residues at amino and carboxy terminal positions of the PD-L1 extracellular domain are also provided. Methods for using such antibodies for the treatment of cancer, particularly PD-L1 positive cancer, are also provided.

  • Publication number: 20200131266
    Abstract: Provided herein are methods for treating cancer using molecules having an antigen binding fragment that immunospecifically binds to BTN1A1, such as anti-BTN1A1 antibodies. These molecules include those having an antigen binding fragment that immunospecifically binds to glycosylated BTN1A1, such as anti-glycosylated BTN1A1 antibodies. Also included are molecules having an antigen binding fragment that immunospecifically bind to BTN1A1 dimers, such as anti-BTN1A1 dimer antibodies. Also provided are methods for treating anti-PD-1 therapy or anti-PD-L1 therapy resistant or refractory cancers.

  • Patent number: 8853264
    Abstract: The present invention relates to the use of lignan compounds for treating or preventing an inflammatory disease. More particularly, it relates to a method for preventing or treating an inflammatory disease, comprising administering to a subject in need thereof an effective amount of macelignan represented by Chemical Formula I or a pharmaceutically acceptable salt thereof. The lignan compound has the effect of inhibiting inflammatory reactions by inhibiting the production or expression of inflammation mediators NO, iNOS, PGE2, COX-2 and TNF-? and by treating or preventing inflammatory disease in vivo. Accordingly, the lignan compound or a Myristica fragrans extract will be highly useful for the treatment or prevention of an inflammatory disease.
