  • Patent number: 12195543
    Abstract: The present invention provides novel human fins related tyrosine kinase 3 (FLT3) antigen binding proteins, such as antibodies, having improved FLT3 binding affinity, and/or anti-tumor activity. The FLT3 antibodies of the invention were generated by mutation of a parent FLT3 antibody and tested in in vitro in binding assays as well as in vivo in a mouse tumor model and in human patient tumor samples. The antibodies of the invention are provided as monospecific constructs or in a bispecific FLT3×CD3 antibody format and show excellent target affinity and/or tumor cell killing. The present invention also relates methods for producing the antigen binding proteins of the invention as well as nucleic acids encoding them, vectors for and host cells for their expression. The invention further relates to methods of treating or diagnosing a disease such as leukemia using an FLT3 antigen binding protein (ABP) of the invention.

  • Publication number: 20230406961
    Abstract: The present invention provides a novel bispecific anti-CD28 antibody format which is bivalent and comprises two CD28 binding sites, and at least one target binding site. The bispecific anti CD28 antibody of the invention is surprisingly advantageous due to its costimulatory activity which is strictly target cell restricted. The bispecific CD28 antibody of the invention is provided for use in the treatment of diseases either alone or in combination with a further bispecific antibody inducing a CD3/T cell receptor signal.

  • Publication number: 20230132249
    Abstract: The present invention provides a novel PSMA binding antibody termed 10B3 and pharmaceutical and diagnostic uses of the antibody 10B3. The PSMA antibody 10B3 does not cross-compete with the state of the art PMSA binding antibody J591 and has a reduced induction of antigen shift compared to J591 and a unique reactivity with squamous cell carcinoma (SCC) cells of different origin.

  • Publication number: 20230007977
    Abstract: The invention pertains to antibodies or other antigen binding proteins targeting the CD276 antigen, also known as B7-H3. The invention provides an improved set of antibodies which bind at new positions within the CD276 antigen and are of particular use as therapeutics in the treatment of CD276 positive cancer. Further the invention provides antibody conjugate and bispecific antibodies which were developed on basis of the novel anti-CD276 antibodies of the invention. Furthermore, the invention discloses the therapeutic use of the antibodies and other modulators in the treatment of CD276 positive cancer. Finally, the nucleic acid constructs encoding the molecules of the invention, recombinant cells expressing them, as well as particular uses and methods are provided.
