  • Publication number: 20230203162
    Abstract: The present invention relates to a multispecific antibody comprising two antibody-based binding domains, which specifically binds to mesothelin (MSLN-BD); and at least one antibody-based binding domain, which specifically binds to CD3 (CD3-BD); wherein said multispecific antibody does not comprise an immunoglobulin Fc region polypeptide, and wherein each of said MSLN-BD binds to mesothelin (MSLN) with a monovalent dissociation constant (KD) in the range of from 0.5 to 20 nM, when measured by SPR. The present invention further relates to nucleic acid sequence(s) encoding said multispecific antibody, vector(s) comprising aid nucleic acid sequence(s), host cell(s) comprising said nucleic acid sequence(s) or said vector(s), and a method of producing said multispecific antibody. Additionally, the present invention relates to pharmaceutical compositions comprising said multispecific antibody and methods of use thereof.

  • Patent number: 8936785
    Abstract: scFv antibodies which specifically bind selected antigens and are obtainable by a method comprising (i) selecting from a pool of soluble and stable antibody frameworks a soluble and stable framework matching best the framework of a non-human antibody against the antigen with a certain binding specificity, (ii) either providing said soluble and stable framework with CDRs that bind specifically to said antigen, or mutating the framework of said non-human antibody towards the sequence of said soluble and stable framework, to generate scFv antibodies, (iii) testing the generated antibody for solubility and stability, and testing the generated antibody for antigen binding, and (iv) selecting an scFV that is soluble, stable and binds to the antigen specifically. Also provided are pharmaceutical compositions comprising said scFv antibody, methods of treatment and diagnosis for diseases related to over expression of antigens that are specifically bound by said antibody.
