  Purpose

The goal of this clinical research study is to learn if Tarceva® (erlotinib hydrochloride) can help control triple receptor-negative breast cancer. The safety of this drug will also be studied.

Objectives:

To assess the clinical efficacy, biologic effects and safety of the EGFR inhibitor erlotinib in the treatment of patients with 'triple receptor-negative' metastatic carcinoma of the breast.

Primary endpoints:

1) Time to progression (TTP)

Secondary endpoints:

  1. clinical benefit rate as defined by complete and partial response and stable disease
  2. overall survival (OS)
  3. safety profile and tolerability of erlotinib
  4. biologic correlative studies

Primary Outcome Measures:
  • Time to Progression (TTP) [ Time Frame: Baseline to disease progression, up to 22 months with follow up. ] [ Designated as safety issue: No ]
    Time to progression calculated from the date of study entry to the date of disease progression or death. Progression of disease is defined by RECIST (Response Evaluation Criteria In Solid Tumors) criteria, as measurable increase in the smallest dimension of any target or not-target lesion, or the appearance of new lesions, since baseline. Confirmed response based on two tumor assessments (imaging) separated by at least 4 weeks.

Other Names:

  • OSI-774

Detailed Description:

The Study Drug:

Erlotinib hydrochloride is designed to block the activity of a protein found on the surface of many tumor cells that may control tumor growth and survival. This may stop tumors from growing.

Screening Tests:

Before you can start treatment on this study, you will have "screening tests." These tests will help the doctor decide if you are eligible to take part in this study.

  • Blood (about 5 teaspoons) will be drawn for routine tests.
  • If you have had a biopsy at M. D. Anderson, your leftover tissue will be used to confirm the breast cancer is triple receptor-negative.
  • If you have had a biopsy at another location, a part of that biopsy will be collected and tested to make sure that the breast cancer is triple receptor-negative.
  • You will have imaging scans, such as computed tomography (CT) or bone scans, to check the status of the disease.
  • If no tissue is available to check the status of the disease, you will have a breast biopsy. To collect a tumor biopsy, the affected area is numbed with anesthetic, and a small amount of tissue is withdrawn through a large needle.

Study Drug Dose Level:

If you are found to be eligible to take part in this study, you will take erlotinib hydrochloride by mouth once a day, every day, between breakfast and lunch. You should take erlotinib hydrochloride 1 hour before or 2 hours after eating. It should be taken at the same time each day.

Study Visits:

Every 8 weeks, the following tests and procedures will be performed:

  • You will have a physical exam.
  • Blood (about 5 teaspoons) will be drawn for routine tests.
  • You will have the same imaging scans that were performed at screening to check the status of the disease.
  • You will be asked about any side effects you may be experiencing.

Length of Study:

You may remain on this study for as long as you are benefiting. You will be taken off this study if the disease gets worse or intolerable side effects occur.

End-of-Study Visit:

You will have an end-of-study visit once you are off this study. The following tests and procedures will be performed at this visit.

Blood (about 5 teaspoons) will be drawn for routine tests. You will have the same imaging scans repeated to check the status of the disease.

This is an investigational study. Erlotinib hydrochloride is FDA approved and commercially available for the treatment of advanced lung cancer and advanced pancreatic cancer. Its use in breast cancer is investigational. Up to 50 patients will take part in this study. All will be enrolled at M. D. Anderson.

  Eligibility

Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Patients with histologic confirmation of metastatic (stage IV) 'triple receptor-negative' breast cancer. Tissue must be available at baseline or agree to biopsy. The diagnosis of 'triple receptor-negative' breast cancer requires that either the primary tumor or a metastatic deposit be shown to be negative for estrogen receptors (ER) and progesterone receptors (PR) by immunohistochemistry (IHC) and for HER2/neu by IHC (i.e. a score of 0 and 1+) or fluorescent in situ hybridization (FISH).
  2. EGFR protein expression and gene copy number will be evaluated on stored tissue sample at a later time. Unstained slides, a block, or agreement for biopsy is required for study participation.
  3. Patients with metastatic breast cancer to any distant site are eligible once their disease is clinically/radiologically measurable
  4. Patients must have disease which is resistant to taxanes and anthracyclines. There is no limit to the number of previous therapies for metastatic disease.
  5. Patients are eligible if they have not had prior exposure to an EGFR inhibitor (e.g.Gefitinib, Erlotinib) or antibody (e.g. Cetuximab).
  6. Availability of tissue blocks and/or fresh/frozen tumor samples is an eligibility requirement in order to run the EGFR IHC, FISH and to confirm, if needed ER, PR and HER2/neu status.
  7. Patients may, but are not required, to have a repeat tumor biopsy performed on study entry prior to beginning therapy and also early during study therapy for correlative studies.
  8. Patients with 'triple receptor-negative' metaplastic breast cancers are eligible if they meet the criterion of EGFR overexpression.
  9. Patients must sign an informed consent indicating that they are aware of the investigational nature of the study, in keeping with institutional policy
  10. Patients must have tissue blocks available from previous primary tumor surgery or biopsy or from a previous biopsy of metastatic disease for EGFR status assessment and for correlative studies
  11. Patients should have adequate bone marrow function, as defined by peripheral granulocyte count of >/= 1500/mm^3, and a platelet count >/= 100000/ mm^3. Patients must have adequate liver function with a bilirubin within 1.5 times the upper limit of normal (ULN). Transaminases (SGPT) may be up to 5 * the ULN and alkaline phosphatase may be up to 5 * ULN
  12. Patients should have adequate renal function (serum creatinine </= 1.5 times the ULN)
  13. Negative pregnancy test for a woman of childbearing potential
  14. Women of childbearing potential must use a reliable and appropriate contraceptive method during the study
  15. Patients with a performance status of 2 or better by World Health Organization (W.H.O.)

Exclusion Criteria:

  1. Patients with uncompensated congestive cardiac failure are not eligible
  2. Patients with a myocardial infarction in the previous 12 months are not eligible
  3. Patients with central nervous system (CNS) metastases are not eligible
  4. Patients with an organ allograft
  5. Patients with a serious concurrent infection or illness including, but not limited to, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness that would limit compliance with study requirements
