Brief Summary:

This study has the purpose to demonstrate clinical efficacy of the investigational new drug ertumaxomab in patients with human epidermal growth factor receptor-2 (HER-2/neu) overexpressing (3+ or 2+ with a positive Fluorescence In Situ Hybridization (FISH) test result) metastatic breast cancer progressing after trastuzumab treatment.

Ertumaxomab is a trifunctional bispecific antibody targeting Her-2/neu on tumor cells and CD3 on T cells. Trifunctional antibodies represent a new concept for targeted anticancer therapy. This new antibody class has the capability to redirect T cells and accessory immune effector cells (e.g. macrophages, dendritic cells [DCs] and natural killer [NK] cells) to the tumor site. According to preclinical data, trifunctional antibodies activate these immune cells, which can trigger a complex anti-tumor immune response.

Actual Enrollment : 19 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

Intervention Details:
    Drug: ertumaxomab
    Ertumaxomab will be intravenously administered to see if it can increase the patient's objective response rate.


Primary Outcome Measures :
  1. Clinical Efficacy Measured by Objective Response Rate (Best Response During the Course of the Study) [ Time Frame: patients are monitored for 6 months ]

Secondary Outcome Measures :
  1. Duration of Response [ Time Frame: patients are monitored for 6 months ]
    The study was prematurely terminated, therefore no participants were analyzed

  2. Clinical Benefit Rate [ Time Frame: patients are monitored for 6 months ]
    The study was prematurely terminated, therefore no participants were analyzed
