简要总结
In the second-line treatment setting for MBC, many agents, including antitubulin drugs (Taxanes, Vinorelbine) and antimetabolites (Capecitabine, Gemcitabine), have demonstrated activity, but no agent is clearly superior. Although some combinations of cytotoxic agents provide a small progression-free survival advantage, none has demonstrated an OS advantage, and toxicity is generally greater than for single agents. At present, there is no standard for this treatment setting. New treatments that could delay disease progression without systemic toxicity would represent a significant advancement.
详细描述
Metastatic breast cancer (MBC) is incurable, and the majority of patients succumb to their disease within 2 years of diagnosis.
Patients with MBC usually receive treatment with endocrine or cytotoxic chemotherapeutic agents, and treatment decisions are generally guided by the hormone receptor and Human Epidermal Growth Factor Receptor 2-Negative status of the disease, the number and location of metastases, and prior treatment history in both adjuvant and metastatic settings. In first- and second-line treatment settings of Metastatic Breast Cancer, numerous cytotoxic chemotherapy agents have demonstrated activity, including anti-tubulin drugs (Taxanes, Vinorelbine), Anthracyclines, and anti-metabolites (Capecitabine, Gemcitabine). However, no single agent has demonstrated a clear survival advantage over another, and use of sequential single-agent therapies is the most frequent approach. The choice of chemotherapy agent(s) is often determined by a number of factors, including history of prior therapy, treatment-free interval, and patient preference. Thus, no single standard treatment exists for patients with advanced disease. Patients who progress during or after their first treatment for Metastatic Brest Cancer typically have a short progression-free interval of 4-6 months and survive for 8-12 months. New treatment modalities are needed to improve clinical outcome and maintain the quality of life for these patients.

入选标准
- •Signed informed consent prior to initiation of any study-specific procedures or treatment, as confirmation of the patient's awareness and willingness to comply with the study requirements.
- •Female patients ≥18 years of age.
- •Histologically confirmed Human Epidermal Growth Factor Receptor 2-Negative adenocarcinoma of the breast with documented progression of disease per investigator assessment following or during first-line treatment with Bevacizumab in combination with Paclitaxel for MBC; patients can have measurable or non-measurable disease. A minimum of 4 cycles of Bevacizumab 15 mg/kg or 6 cycles 10 mg/kg received in the first-line setting.
- •Patients must have received Bevacizumab in combination with Paclitaxel as first line treatment. As part of their first line maintenance treatment, patients may have received:
- •Bevacizumab monotherapy
- •Bevacizumab in combination with endocrine treatment
- •Nothing (for a period ≤ 6 weeks from the last Bevacizumab treatment)
- •ECOG performance status (PS) of 0-
- •At least 28 days since prior radiation therapy or surgery and recovery from treatment.
- •Patients must have measurable disease which must be evaluable per RECIST v1.
- •Estimated life expectancy of ≥12 weeks.
排除标准
- •Disease-specific exclusions
- •Patients who have received anti-angiogenic therapy [e.g. tyrosine kinase inhibitors (TKIs) or anti-vascular endothelial growth factors (anti-VEGFs)] other than Bevacizumab for the first-line treatment of MBC.
- •Patients who have exclusively received endocrine treatment in combination with Bevacizumab until the first progression.
- •Positive or unknown Human Epidermal Growth Factor Receptor 2/neu status or for whom determination of Human Epidermal Growth Factor Receptor 2 status is not possible. In general, Human Epidermal Growth Factor Receptor 2 positive status will be identified by a FISH assay as evaluated at the institution, or, if FISH is unavailable, a 2+ or 3+ immunohistochemistry result (but method of identification may vary by region or institution).
- •Current, recent (within 4 weeks or 2 half-lives, whichever is greater, before day 1) or planned participation in an experimental drug study - other than a Bevacizumab breast cancer study.
- •Active malignancy, other than superficial basal cell and superficial squamous (skin) cell, or carcinoma in situ of the cervix or breast within the last 5 years.
- •Any laboratory values at baseline as described in the protocol;
- •Psychiatric or addictive disorders or other conditions that, in the opinion of the investigator, would prevent the patient from meeting the study requirements.
- •Serious active infection requiring i.v. antibiotics and/or hospitalization at study entry.
- •Patients who are treated with any medicinal product that contraindicates the use of any of the study drugs, may interfere with the planned treatment, affects patient compliance or puts the patient at high risk for treatment-related complications.
- •Bevacizumab-specific exclusions: (see protocol)
- •Eribulin-specific exclusions: (see protocol)

结局指标
主要结局
Overall Response rate
时间窗: Patients enrolled will receive study medication until disease progression, unacceptable toxicity, withdrawal of consent or death, whichever comes first, assessed up to 30 months
ORR will be evaluated for those patients who have a response to second-line treatment as defined per RECIST version 1.1 in patients with measurable disease according to RECIST version 1.1. ORR will be based on the best overall response (BOR) as defined by RECIST Guidelines v. 1.1.
