Herceptin and GM-CSF for Metastatic Breast Cancer
- To determine the patient's tumor response rate that this protocol will produce.
- To determine the 1 year progression-free survival that this protocol will produce.
1. To determine whether antibody-dependent cell-mediated cytotoxicity (ADCC) is the mechanism of overcoming Herceptin-resistance by use of Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF).
|Study Design:||Allocation: Non-Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Phase II Study of GM-CSF to Overcome Herceptin-Resistant HER-2/Neu-Overexpressing Metastatic Breast Cancer|
- Number of Participants With Tumor Response (Stable Disease) [ Time Frame: 2 months ] [ Designated as safety issue: No ]Number of participants with response defined as stable disease or better using Response Evaluation Criteria In Solid Tumors (RECIST) at the month 2 evaluation.
- Duration of Stable Disease [ Time Frame: 6 Years ] [ Designated as safety issue: No ]Stable disease is measured from the start of the treatment until the RECIST criteria for disease progression is met.

Experimental: HER2+ Metastatic Breast Cancer
Herceptin 4 mg/kg IV Over 90 Minutes + GM-CSF 250 mcg/m^2 subcutaneously
4 mg/kg IV Over 90 Minutes
Other Name: TrastuzumabDrug: GM-CSF
250 mcg/m^2 Subcutaneously
GM-CSF stimulates the immune system and may increase the effectiveness of Herceptin.
Before you can start treatment on this study, you will have what are called "screening tests." These tests will help the doctor decide if you are eligible to take part in this study. You will have a complete medical history and physical exam. This includes blood tests (about 2 tea spoons), and x-rays. Women who are able to have children must have a negative blood or urine pregnancy test.
If you are found to be eligible to take part in this study, you will receive trastuzumab through a vein (IV) every week until the disease gets worse. GM-CSF will be injected under the skin at least once a day until the white blood cell count is stable. GM-CSF will also continue during the course of study until the disease progresses.
You will have further evaluation of your disease by computed tomography-CT scan, bone scan, chest X-ray, etc. at 2, 4, 6, 9, 12, 18, and 24 months after the start of treatment. You will have blood tests (about 2 tea spoons) at least twice a week until the appropriate dose of GM-CSF is found. The dose may increase or decrease depending on the blood test.
You will have blood (about 2 tablespoons) drawn before treatment at the 2nd and 4th month, and if the disease gets worse.
You will be removed from the study if the disease is progressing or severe side effects occur.
This is an investigational study. The FDA has approved trastuzumab and GM-CSF, but their use in this study is experimental. A total of 36 patients will take part in this study. All will be enrolled at UT MD Anderson Cancer Center.
