Brief Summary:
The purpose of this study is to determine if MGAH22 is safe when given by intravenous (IV) infusion to patients with HER2-positive cancer. The study will also evaluate how long MGAH22 stays in the blood and how long it takes for it to leave the body, what is the highest dose that can safely be given, and whether it has an effect on tumors.

  16. Number of patients with complete response, partial response, stable disease, or progressive disease according to each CD16A-158 genotype (FF, FV, VV) [ Time Frame: Fc receptor genotypes assessed prior to study treatment. Response to treatment assessed at 6, 18, 30, 42, and 54 weeks, then every 24 weeks until treatment discontinuation, average 10 months ]
    Fc Receptor polymorphisms may affect responsiveness to immunotherapies

  17. Changes in immune cell subsets [ Time Frame: Before infusion and 1 hour after infusion on Study Day 1, Study Day 2, before infusion on Study Day 22 and 50 ]
    Changes in immune cell subsets may affect responsiveness to immunotherapies

  18. Serum cytokines in the blood [ Time Frame: Study Day 1, 2, 4, 5, 22, 29 ,36, 50, every 3 weeks thereafter through study completion, average 10 months ]
    Changes in the levels of cytokines in the blood may be related to an immune response to treatment.

  19. Amount HER2 in the blood [ Time Frame: Before infusion and 1 hour after infusion on Study Day 1, Study Day 2, before infusion on Study Day 22 and 50 ]
    Levels of HER2 in the bloodstream may indicate response to treatment.

  20. Antibody dependent cellular cytotoxicity (ADCC) activity [ Time Frame: Before infusion and 1 hour after infusion on Study Day 1, Study Day 2, before infusion on Study Day 22 and 50 ]
    ADCC activity is the ability of immune cells (like lymphocytes) to kill cells that have immune markers (like HER2) on the cell surface

  21. Fc receptor occupancy [ Time Frame: Before infusion and 1 hour after infusion on Study Day 1, Study Day 2, before infusion on Study Day 22 and 50 ]
    Fc receptor occupancy is the amount of time that the receptor is bound to an immune marker (like HER2) on the cell surface.
