Brief Summary

Treatment of triple negative breast cancer (TNBC) relies heavily on different regimes of chemotherapeutic agents but remains one of the most challenging subtypes to treat because of the lack of specific therapies. Despite being sensitive to chemotherapy, many women with TNBC relapse quickly, developing locoregional recurrence or visceral metastasis. Toxicity and chemotherapy resistance are still major limitations in the treatment of patients with TNBC. Despite current trend of targeted therapy development, cytotoxic agents are a mainstay of treatment of patients with breast cancer. Further research into new combination of different compounds is needed in order to maximise benefit, whilst minimising toxicity. The phosphoinositide 3-kinase (PI3K) pathway is associated with resistance to a variety of anti-tumor agents. This has been described pre-clinically with cytotoxic chemotherapeutic agents with varying mechanisms of action including taxanes, and DNA-damaging agents. In the clinic, activated PI3K in tumors has been correlated with decreased response to therapy and worse clinical outcomes. The recent biological findings suggest that a PI3K/mammalian target of rapamycin (mTOR) inhibitors may increase the efficacy of chemotherapeutic agents which are considered standard of care (SOC) for the treatment of several solid tumors. The study by the Unitaed state Oncology Research of Huston and the Sarah Cannon Cancer Center randomized 1830 patients with high risk breast cancer to the standard adjuvant treatment with adriamicin cyclophosphamide followed by paclitaxel versus the experimental adjuvant treatment with adriamicin taxotere (AT) followed by paclitaxel. At 5-years of follow up, the AT followed by paclitaxel produced significantly better overall survival (p=0.054) and improved disease free survival (DFS) (p=0.19). Among TNBC patients both DFS (74% versus 79%, p=0.1) and overall survival (OS) (79% versus 84%, p=0.037) were better in experimental arm. However, the main reasons for patients being taken off study treatment were toxicity (85 patients in the control arm and 128 in the experimental arm) and consent withdrawal (18 patients in the control arm and 30 patients in the experimental arm). For this reason, research into alternatives has intensified, thus resulting in the discovery and development of new compounds with a more tolerable profile as compared with paclitaxel. Among the total of 762 patients enrolled into Eisai Metastatic Breast Cancer Study Assessing Physician's Choice Versus E7389 (EMBRACE) trial, 19% had TNBC. Of note, eribulin was most effective in hormone receptor-negative patients and in TNBC patients, who had a 29% risk reduction. Treatment with eribulin was well tolerated. Neutropenia, leucopenia, peripheral neuropathy, and asthenia/fatigue were the most common adverse events reported at Common Terminology Criteria for Adverse Events (CTCAE) grades 3 and 4. Neutropenia was the most common adverse events reported at CTCAE grade 4 in the eribulin group (24.1%). Based on findings to date, eribulin is an attractive agent, and its role in combination with new compounds such as everolimus deserves further investigations. Their combination might lead to more profound effects on tumor cell biology of triple negative metastatic breast cancer. During the course of the trial, dose reductions for each combination will be permitted in patients who cannot tolerate the starting dose

Eligibility Criteria

• Age: 18 Years+
• Sex: female
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Age ≥18 years.
• Eastern Cooperative Oncology Group (ECOG) performance Status 0-1
• Triple negative metastatic breast cancer.
• Patients have received at least 1 prior line of chemotherapy in metastatic setting.
• Measurable disease either by clinical exam or radiograph. Patients with measurable disease as determined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.0; measurable disease is defined as at least one lesion that can accurately be measured in at least one dimension as ≥ 20 mm by conventional radiological technique or ≥ 10 mm with spiral CTscan. Cutaneous lesions must have clearly defined margins and measures ≥ 10 mm in at least one diameter and be documented by color photography. Target lesions should not be selected in previously irradiated fields unless there is clear evidence of progression.
• Patients must not have received prior therapy with the investigational drugs.
• Patients must not have received more than 3 prior chemotherapy regimens for triple negative metastatic breast cancer.
• Patients must not be receiving concurrent endocrine therapy or immunotherapy.
• Patients must be willing to provide available tissue specimen, either archival tissue (one block or a minimum of 20 unstained slides) or fresh formalin fixed tumor biopsy, for identification of PI3K pathway activation (mutation /fish).
• Patients must have an expected survival of at least 3 months.
• Patients with absolute neutrophil count (ANC) ≥ 1,5 x 109/l.
• Adequate bone marrow, renal and hepatic functions:
• Hemoglobin (Hgb) ≥ 9 g/dl
• Platelets (PLT) ≥ 100 x 109/L without transfusions within 21 days before 1sttreatment
• AST/SGOT and/or ALT/SGPT ≤ 3.0 x ULN (upper limit of normal) or ≤ 5.0 x ULN if liver metastases are present

You may not qualify if:

• Patients who have received other chemotherapy or other therapies and not recovered from acute toxicity of previous therapy.
• Patients who have received radiotherapy within 4 weeks prior to start of this trial.

• Patients with known evidence of brain metastases or leptomeningeal disease, including patients who continue to require glucocorticoids for brain or leptomeningeal metastases.
• Patients with a history of other cancers except curatively-treated carcinoma of the cervix in situ or non-melanomatous skin cancer. Patients with other cancers thought to be cured may be entered into the trial after discussion with and approval of the study chair.
• Patients with an active serious infection or other serious underlying medical condition that would impair their ability to receive protocol treatment.
• Patients with pre-existing peripheral neuropathy of grade \> 2.
• Patients with history of interstitial pneumonia or pulmonary insufficiency verified with Pulmonary Function Test (PFT) at baseline (PFT at baseline is necessary only in patients with clinical suspect of interstitial pneumonia). - Patients with bone metastases as their only site of measurable disease.
• Dementia or significantly altered mental status that would prohibit the understanding and/or giving of informed consent.
• Pregnant or breast-feeding patients.
• Patients not using adequate methods of birth control if still of child-bearing potential.
• Patients who have received prior therapy with everolimus/temsirolimus/sirolimus or eribulin.
