Abstract: Provided herein are methods for treating or preventing progression of cancer in an individual, comprising administering to the individual an effective amount of an anti-human epidermal growth factor receptor 2 (HER2) antibody-drug conjugate that comprises an anti-HER2 antibody and a cytotoxic molecule.
Abstract: Antibody drug conjugates (ADC's) that bind to 191P4D12 protein and variants thereof are described herein. 191P4D12 exhibits tissue specific expression in normal adult tissue, and is aberrantly expressed in the cancers listed in Table I. Consequently, the ADC's of the invention provide a therapeutic composition for the treatment of cancer.
