Abstract: A composition comprising a main species HER2 antibody that binds to domain II of HER2, and an amino acid sequence variant thereof comprising an amino-terminal leader extension is disclosed. Pharmaceutical formulations comprising the composition, and therapeutic uses for the composition are also disclosed.

Abstract: The present application describes the use of low HER3 as a selection criterion for treating patients with a HER inhibitor, such as pertuzumab. It also describes the use of high HER2:HER3 ratio as a selection criterion for treating cancer patients, such as ovarian cancer patients, with a HER inhibitor, such as pertuzumab. In addition, the application describes the use of high HER3 as a selection criterion for treating cancer patients with a chemotherapeutic agent, for instance gemcitabine.

Abstract: The present application describes therapy with antagonists which bind to B cell surface markers, such as CD20. In particular, the application describes the use of such antagonists to treat autoimmune disease in a mammal who experiences an inadequate response to a TNF?-inhibitor.

Pharmaceutical formulations comprising the composition, and therapeutic uses for the composition are also disclosed.

Abstract: The present application describes humanized anti-ErbB2 antibodies and methods for treating cancer with anti-ErbB2 antibodies, such as humanized anti-ErbB2 antibodies.

Abstract: A variant of a polypeptide comprising a human IgG Fc region is described, which variant comprises an amino acid substitution at one or more of amino acid positions 270, 322, 326, 327, 329, 331, 333 or 334 of the human IgG Fc region. Such variants display altered effector function. For example, C1q binding and/or complement dependent cytotoxicity (CDC) activity may be altered in the variant polypeptide. The application also discloses a variant of a parent polypeptide comprising a human IgG Fc region, which variant has a better binding affinity for human C1q than the parent polypeptide.

Abstract: The present application describes methods for treating cancer with anti-ErbB2 antibodies, such as humanized anti-ErbB2 antibodies, and EGFR-targeted drugs.

Abstract: The present application describes a method for pretreating a biological sample from an autoimmune disease subject in order to avoid interference, especially where the sample is to be subjected to a cell-based biological activity assay, such as a neutralizing antibody assay.

Abstract: A composition comprising a main species HER2 antibody that binds to domain II of HER2, and an amino acid sequence variant thereof comprising an amino-terminal leader extension is disclosed. Pharmaceutical formulations comprising the composition, and therapeutic uses for the composition are also disclosed.

Abstract: The present application describes methods for treating ErbB-expressing cancer with anti-ErbB2 antibody combinations.

Abstract: The present application describes methods for treating cancer with anti-ErbB2 antibodies, such as humanized anti-ErbB2 antibodies, and anti-hormonal compounds, such as anti-estrogens.

Abstract: The present application describes methods for treating cancer with anti-ErbB2 antibodies, such as humanized anti-ErbB2 antibodies, and chemotherapeutic agents.

Abstract: The present invention concerns fixed dosing of HER antibodies, such as Pertuzumab.

Abstract: The present invention concerns polypeptides comprising a variant Fc region. More particularly, the present invention concerns Fc region-containing polypeptides that have altered effector function as a consequence of one or more amino acid modifications in the Fc region thereof.

Abstract: Anti-ErbB2 antibodies are described which bind to an epitope in Domain 1 of ErbB2 and induce cell death via apoptosis. Various uses for these antibodies are also described.

Abstract: The present invention concerns the treatment of disorders characterized by the overexpression of ErbB2. More specifically, the invention concerns the treatment of human patients susceptible to or diagnosed with cancer overexpressing ErbB2 with anti-ErbB2 antibody.

Abstract: The present invention concerns polypeptides comprising a variant Fc region. More particularly, the present invention concerns Fc region-containing polypeptides that have altered effector function as a consequence of one or more amino acid modifications in the Fc region thereof.
