RATIONALE: Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Cetuximab may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving cetuximab together with carboplatin is more effective than giving cetuximab alone in treating metastatic breast cancer.
PURPOSE: This randomized phase II trial is studying cetuximab and carboplatin to see how well they work compared with cetuximab alone in treating women with estrogen receptor-negative (ER-), progesterone receptor-negative (PR-) metastatic breast cancer.
|Condition or disease||Intervention/treatment||Phase|
|Breast Cancer||Biological: cetuximab Drug: carboplatin||Phase 2|
- Compare the overall response rate in women with estrogen receptor-negative, progesterone receptor-negative, human epidermal growth factor receptor 2 (HER2)-nonoverexpressing metastatic breast cancer treated with cetuximab with vs without carboplatin.
- Compare the time to disease progression in patients treated with these regimens.
- Correlate downstream effects of epidermal growth factor receptor (EGFR) inhibitor on Mitogen-activated protein kinases (MAPK), Protein kinase B (AKT), monoclonal antibody Ki-67 (Ki67), and EGFR-dependent signaling, proliferation, and apoptosis with toxicity and response in patients with accessible tumors treated with these regimens.
- Determine the changes in biomarkers and gene expression in circulating tumor cells during treatment.
- Compare the overall survival rate in patients treated with these regimens.
OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive cetuximab IV over 60-120 minutes once a week.
- Arm II: Patients receive cetuximab as in arm I and carboplatin IV on days 1, 8, and 15.
In both arms, treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. Patients not responding to treatment in arm I may cross over to arm II.
Blood samples are collected periodically throughout study for correlative biomarker analysis by Immunohistochemistry (IHC) and gene expression analysis.
After completion of study treatment, patients are followed every 4 months.

- Overall Disease Response Rate [ Time Frame: 5 years ]Overall response rate of single agent cetuximab and cetuximab + carboplatin will be measured by radiographic response using Response Evaluation Criteria In Solid Tumors (RECIST) criteria every 8 weeks until subject experiences disease progression. Overall response will be measured as complete response (CR), partial response (PR), stable disease (SD) or progressive disease (PD).Per RECIST v1.0 for target lesions and assessed by CT (spiral): Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Progression, as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions; Stable Disease (SD), neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for disease progression
- Overall Survival [ Time Frame: Every four months until death of any cause or end of data collection up to 40 months ]Subjects will be contacted every 4 months after discontinuation of active treatment to assess survival.
- Progression-Free Survival [ Time Frame: Every four months until progression, death of any cause, or end of data collection up to 40 months ]Time to disease progression of cetuximab or cetuximab + carboplatin as indicated by radiographic assessment
