简要总结
Previous studies have shown that chemotherapy has the same effect on treating breast cancer whether you receive it before or after surgery. Receiving chemotherapy before surgery, rather than after surgery, may allow the patient to have less extensive surgery. The purpose of this study is to identify new treatment regimens with better response rates and to find out if the combination of eribulin followed by doxorubicin and cyclophosphamide can shrink the size of the patient's breast tumor and allow you to preserve your breast. Additionally, by receiving chemotherapy before surgery, the investigators will be able to determine if your cancer is responsive to chemotherapy.
详细描述
This is a phase 2, single-arm, open label study. Patients with Her2-negative, locally advanced breast cancer will be enrolled on the study prior to receiving neoadjuvant chemotherapy. Patients will receive 4 cycles of neoadjuvant eribulin followed by 4 cycles of dose-dense doxorubicin and cyclophosphamide (AC).
All patients will have a baseline biopsy prior to study entry to determine eligibility. Patients will undergo repeat breast imaging and optional biopsy after completing 4 cycles of eribulin. Patients will then receive 4 cycles of dose-dense AC. Patients will undergo repeat breast imaging followed by surgical resection within 30 days of completing last cycle of chemotherapy. Patients who are not surgical candidates after completion of chemotherapy will be asked to undergo optional repeat biopsy prior to receiving additional treatment at the discretion of the investigator. Patients will continue to be followed per standard practice guideline after surgery
Clinical response will be determined by clinical breast examination prior to each cycle of chemotherapy and by breast imaging performed at baseline, after completion of eribulin, and prior to surgery. Pathologic complete response (pCR) will be determined at the time of surgical resection. Correlative biomarker studies will be performed on tumor samples at the completion of the clinical trial.

排除标准

Patients with history of breast cancer greater than 5 years from initial diagnosis are eligible for the study. Patients may not have received anthracycline-based chemotherapy in the past. Patients with history of ductal carcinoma in situ (DCIS) are eligible if there were treated with surgery alone.
- •Medical, psychological or surgical condition which the investigator feels might compromise study participation.
- •History of previous or current malignancy at other sites with the exception of adequately treated carcinoma in-situ of the cervix or basal or squamous cell carcinoma of the skin. Patients with a history of other malignancies, who remain disease free for greater than five years are eligible.
- •Evidence of sensory and/or peripheral neuropathy > grade
- •Serious, uncontrolled, concurrent infection(s).
- •Major surgery within 4 weeks of the start of study treatment, without complete recovery.
- •Pregnant or lactating women are not eligible. Women of childbearing potential must have a negative serum or urine pregnancy test completed within 7 days of study treatment. Women or men of childbearing potential not using a reliable and appropriate contraceptive method are not eligible. (Postmenopausal woman must have been amenorrheic for at least 12 months to be considered of non-childbearing potential).
- •Known human immunodeficiency virus (HIV) infection or chronic Hepatitis B or C.
- •Active clinically serious infection > CTCAE Grade
- •Thromboembolic events such as a cerebrovascular accident including transient ischemic attacks within the past 6 months.

- •Known brain metastasis. Patients with neurological symptoms must undergo a CT scan/MRI of the brain to exclude brain metastasis.
- •Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy.
- •Uncontrolled hypertension defined as systolic blood pressure > 150 mmHg or diastolic pressure > 90 mmHg, despite optimal medical management.

结局指标
主要结局
Pathologic Complete Response Rate at the Time of Surgery
时间窗: Average of 24 weeks
Patients will receive treatment for 20 weeks with primary outcome measured at the time of surgery. Surgery is typically 4-6 weeks after completion of chemotherapy, so patients will be on study for 24 weeks on average. Response was measured by pathologist's standard of care assessment of extent of residual disease. If the patient had no evidence of invasive or in situ residual disease present in the breast and lymph node (i.e. ypT0N0), then this was defined as a pathologic complete response (pCR). Reported is the number of participants showing pCR.
