  • Patent number: 11820821
    Abstract: The present invention relates to an antigen-binding protein, or an antigen-binding fragment thereof which binding to CEACAM6, comprising (i) a heavy chain variable domain comprising a VHCDR1 having the amino acid sequence GNTFTSYVMH; a VHCDR2 having the amino acid sequence YINPYNDGTKYNEKFKG; and a VHCDR3 having the amino acid sequence STARATPYFYAMDY and (ii) a light chain variable domain comprising a VLCDR1 having the amino acid sequence KSSQSLLWSVNQNSYLS, a VLCDR2 having the amino acid sequence GASIRES, and a VLCDR3 having the amino acid sequence QHNHGSFLPYT. The present invention also relates to compositions comprising the antigen-binding protein, or antigen-binding fragment thereof, methods of use of the antigen-binding protein, or antigen-binding fragment thereof for cancer treatment, prevention or detection and a kit comprising the antigen-binding protein, or antigen-binding fragment thereof.

  • Patent number: 11274348
    Abstract: The present invention refers to a method of predicting susceptibility of a subject suffering from cancer to a treatment with an anti-cancer drug, wherein the method comprises detecting the presence or absence of a genetic alteration in a long non-coding RNA (IncRNA) that resides in an antisense strand of an oncogene, wherein the genetic alteration disrupts expression of the oncogene, and wherein the subject is predicted to be more susceptible to the treatment if the genetic alteration is present. In particular, the genetic alteration is a silent G>A mutation at Q787Q of the oncogene epidermal growth factor receptor (EGFR). Also disclosed herein is a method of treating a subject suffering from cancer, who was shown to have a genetic alteration in IncRNA that resides in an antisense strand of an oncogene.
