Phase 2 Study of Trastuzumab and Etoposide for Her2 Positive Breast Cancer - Full Text View

Purpose

This study is for women and men who have previously treated metastatic (has spread to other parts in the body), Her2- positive breast cancer. The purpose of this study is to find out what effects (good and bad) the FDA-approved drugs etoposide and trastuzumab have on this type of breast cancer and to determine if these drugs are safe to use together. This research is being done to find more effective treatment for this type of condition.

In this study, trastuzumab and etoposide will be given by intravenous infusion (IV; through a vein) on the first 3 days of every 3-week cycle. This is repeated for 6 cycles. After 6 cycles, only trastuzumab will be given until worsening of disease. In this study, a small amount of your tissue that was collected when you had surgery will be evaluated in the lab to look at genetic differences among people and how those differences may affect a response to a specific drug or medicine. This testing will look for a gene called Top2A. Previous studies suggest that people who have both the Top2A and Her2 genes respond to certain chemotherapies (anti-cancer drugs) differently from those who only have the Her2 gene.

Primary Outcome Measures:

To determine efficacy of trastuzumab combined with etoposide in patients with HER2-positive metastatic breast cancer, and to assess toxicity of the combination of trastuzumab with intravenous etoposide. [ Time Frame: quarterly ]

Secondary Outcome Measures:

To explore relationship of amplification or deletion of the TOP2A gene to efficacy of trastuzumab combined with etoposide in patients with HER2 positive metastatic breast cancer. [ Time Frame: yearly ]

Criteria

Inclusion Criteria:

Females or males with histologic confirmation of breast carcinoma and diagnosis of metastatic breast adenocarcinoma
Confirmed HER2 amplification by immunohistochemical staining (IHC) 3+ or FISH amplified (either primary or metastatic).
Have had any number of prior HER2 targeted therapy containing chemotherapies for treatment of breast cancer
Measurable extent of disease
Life expectancy of 3 months or greater
Patients must have adequate heart function, determined with ECHO or MUGA (ECHO preferred).
Patients must have adequate bone marrow and organ function
Patient of childbearing potential must be willing to use an effective means of contraception during their participation on trial
Greater than 3 weeks from prior radiation or chemotherapy; more than 1 week from prior hormonal therapy; and more than 6 weeks from prior treatment with nitrosoureas or mitomycin.
No serious intercurrent medical illness.
Controlled metastatic CNS disease ≥ 3 months
The ability to understand and willingness to sign a written informed consent form, and to comply with the protocol.

Exclusion Criteria:

Pregnant or nursing women
Patients who are poor medical risk because of other non-malignant systemic disease or active, uncontrolled infection.
Prior craniospinal radiation, or total body irradiation (TBI).
Patients receiving G-CSF (filgrastim or pegfilgrastim) or thrombopoietin (or other platelet growth factors) within the 3 weeks prior to enrollment (erythropoietin is allowed).
Prior chemotherapy within the last 3 weeks (last 6 weeks for nitrosureas/mitomycin).
Prior radiation therapy within the last 3 weeks; prior radiation therapy to indicator lesion (unless objective disease recurrence or progression within the radiation portal has been documented since completion of radiation).
Concomitant malignancies or previous malignancies within the last 5 years, with the exception of adequately treated basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix.
Current symptoms of angina or uncontrolled arrhythmias, uncontrolled hypertension with systolic blood pressure >=170 or diastolic blood pressure >=110.
Psychiatric illness precluding participation in study
Symptomatic intrinsic lung disease or extensive tumor involvement of the lungs, resulting in dyspnea at rest.
Carcinomatous meningitis or CNS mets not controlled for ≥ 3 months.
