Abstract: A method for increasing the therapeutic efficacy of a human immunoglobulin G class 1 (IgG1) antibody, includes: mutating the human CH1?1 domain from the antibody, to restore the pairing between CH1 and CL domains that is typical of the other IgG subclasses, or by substituting the human CH1?1 domain by the CH1 domain from a human IgG2 (CH1?2), IgG3 (CH1?3) or IgG4 (CH1?4); the antibody obtained by such method, includes a) a light chain including the following amino acid sequences: i) the Light Chain Variable Region (LCVR) specific from an antigen; and ii) a human kappa (?)Constant (CL) domain; and b) a heavy chain including the following amino acid sequences: i) the Heavy Chain Variable Region (HCVR) specific from the antigen; ii) the CH2 and CH3 domains from a human IgG1; and iii) the CH1 domain from a human IgG1, mutated to restore pairing between CHI and CL domains.

Abstract: The invention relates to single domain VHH fragments which specifically bind to and inhibit superoxide dismutase and/or bind to and inhibit catalase and/or bind to and inhibit superoxide dismutase and catalase, in particular for the use in the therapy of tumor diseases.
Abstract: The present invention relates to Tri-Specific Binding Molecules, which are multi-chain polypeptide molecules that possess three Binding Domains and are thus capable of mediating coordinated binding to three epitopes. The Binding Domains may be selected such that the Tri-Specific Binding Molecules are capable of binding to any three different epitopes. Such epitopes may be epitopes of the same antigen or epitopes of two or three different antigens. In a preferred embodiment, one of such epitopes will be capable of binding to CD3, the second of such epitopes will be capable of binding to CD8, and the third of such epitopes will be capable of binding to an epitope of a Disease-Associated Antigen. The invention also provides a novel ROR1-binding antibody, as well as derivatives thereof and uses for such compositions.

Abstract: The present invention relates to Tri-Specific Binding Molecules, which are multi-chain polypeptide molecules that possess three Binding Domains and are thus capable of mediating coordinated binding to three epitopes. The Tri-Specific Binding Molecule is preferably characterized in possessing binding domains that permit it to immunospecifically bind to: (1) an epitope of a first Cancer Antigen, (2) an epitope of a second Cancer Antigen, and (3) an epitope of a molecule that is expressed on the surface of an immune system effector cell, and are thus capable of localizing an immune system effector cell to a cell that expresses a Cancer Antigen, so as to thereby facilitate the killing of such cancer cell.

Abstract: The present invention relates to a bispecific (monoclonal) antibody molecule with a first binding domain binding an antigen on CD8+ T-cells that does not naturally occur in and/or on CD8+ T-cells and a second binding domain binding to a tumor specific antigen naturally occurring on the surface of a tumor cell. The bispecific (monoclonal) antibody molecules are particularly useful in combination with transduced CD8+ T-cells comprising an antigen which does not naturally occur in and/or on CD8+ T-cells and/or a T-cell receptor.

Abstract: The present disclosure relates to a novel class of anti-HER2 monoclonal antibodies comprising a homogeneous population of anti-HER2 IgG molecules having the same N-glycan on each of Fc. The antibodies of the invention can be produced from anti-HER2 monoclonal antibodies by Fc glycoengineering. Importantly, the antibodies of the invention have improved therapeutic values with increased ADCC activity and increased Fc receptor binding affinity compared to the corresponding monoclonal antibodies that have not been glycoengineered.
Abstract: The present invention comprises human monoclonal antibodies that bind to PD-L1 (also known as programmed death ligand 1 or B7H1). Binding of the invented antibody to PD-L1 inhibits binding to its receptor, PD1 (programmed death 1), and ligand-mediated activities and can be used to treat cancer and chronic viral infections.
Abstract: The present disclosure relates to compositions and methods for enhancing T cell response and/or CAR cell expansion in vivo and/or in vitro. For example, a cell may comprise a first chimeric antigen receptor (CAR) and a second CAR, wherein a binding domain of the first CAR binds a first antigen, and a binding domain of the second CAR binds a second antigen. The first antigen is different from the second antigen. In embodiments, the first CAR may recognize a surface molecule of a blood cell.
