Estimating the term…
The present invention relates to anti-HER2 binding molecules (e.g., antibodies and antigen binding fragments thereof), derived HER2-binding molecules (e.g., bispecific anti-HER2 antibodies), and antibody-drug conjugates (ADC) that bind the extracellular domain of the HER2 receptor. Also provided are pharmaceutical formulation comprising the disclosed compositions and method for the treating diseases associated with HER2-mediated signal transduction.
A bispecific anti-HER2 antibody comprising a first immunoglobulin antigen-binding domain and a second immunoglobulin antigen-binding domain, wherein (i) the first and second immunoglobulin antigen-binding domains specifically bind to distinct HER2 antibody binding sites, (ii) the first immunoglobulin antigen-binding domain binds to a first HER2 antibody binding site which comprises an epitope within domain II of HER2, and (iii) the first HER2 antibody binding site is distinct from the antibody binding site of pertuzumab.
A bispecific anti-HER2 antibody comprising a first immunoglobulin antigen binding-domain and a second immunoglobulin antigen-binding domain, wherein the first immunoglobulin antigen-binding domain comprises a VH and a VL, wherein
