Brief Summary

The purpose of this study is to determine the safety and tolerability of rebastinib when combined with antitubulin therapy with paclitaxel or eribulin in patients with advanced breast cancer.

Detailed Description

Metastasis is the primary cause of death from breast cancer, invasive carcinoma cells in mouse and rat mammary tumors co-migrate accompanied by macrophages towards intravasation sites . The intravasation occurs at sites where a TIE2-expressing macrophage, a mena-expressing tumor cell, and an endothelial cell are in direct contact, forming a micro-anatomic structure called tumor micro-environment of metastasis (TMEM). Ablation of the presence or activity of the TMEM associated macrophages blocks intravasation at TMEM demonstrating an essential role of perivascular macrophages in TMEM function. Rebastinib, a TIE2 inhibitor , blocks TMEM assembly and function in-vivo and in-vitro assays. We hypothesize that rebastinib combined with antitubulin therapy (eribulin or paclitaxel) could improve clinical outcomes in breast cancer by preventing intravasation at TMEM sites and preventing further metastasis.

Eligibility Criteria

Inclusion Criteria

1. Histologically confirmed adenocarcinoma of the breast that is HER2 (human epidermal growth factor receptor 2) negative; based on ASCO(american society of clinical oncology)/ CAP (college of American Pathologists) guidelines as: (a) IHC (immuno-histochemistry) 1+ negative or IHC 0 negative; or (b) ISH (in situ hybridization ) negative using single probe ISH( average HER2 copy number < 4.0 signals/cell), or dual probe ISH ( HER2/CEP17 ratio <2.0, average HER2 copy number <4.0 signals/cell)

2. Metastatic breast cancer not amenable to potentially curative surgery. Patients must have disease that is measurable and/or non-measurable as defined by RECIST 1.1 criteria

3. Prior chemotherapy and/or endocrine therapy. Patients will be assigned to arm A or arm B depending on their prior exposure to paclitaxel and eribulin.

• Arm A: Rebastinib plus paclitaxel: Up to two prior non-taxane chemotherapy regimens for metastatic or incurable locally advanced disease permitted (no prior paclitaxel, docetaxel, or eribulin for metastatic disease)..Prior therapy with paclitaxel or docetaxel in the neo/adjuvant setting is allowable if there is at least a 6 month interval between the last adjuvant/neoadjuvant paclitaxel or docetaxel dose and recurrence.
• Arm B: Rebastinib plus Eribulin: Patients must have previously received at least two chemotherapeutic regimens for the treatment of metastatic disease (no prior eribulin, but prior paclitaxel, nab-paclitaxel, or docetaxel allowed). Prior therapy should have included a taxane in either the adjuvant or metastatic setting.
• Arms A and B: Patients with hormone receptor positive disease must have had progressive disease and at least 2 lines of endocrine therapy, including one endocrine regimen used in combination with an approved CDK 4/6 (cyclin-dependent kinase ) inhibitor (eg, palbociclib). Relapse while receiving or within 6 months of completing adjuvant endocrine therapy may be considered failure of one prior endocrine regimen

4. Female and age >18 years. Because breast carcinoma is a disease of adults that rarely occurs in children, children are excluded from this study. In addition, the safety of rebastinib in pediatric patients has not been evaluated.

5. ECOG (Eastern Cooperative Oncology Group) performance status 0 or 1.

6. Normal organ and marrow function as defined below within 2 weeks of registration (except where specified otherwise):

Leukocytes >3,000/µL ; Absolute neutrophil count >1,500/µL ; Platelets >100,000/ µL Hemoglobin > 9 g/dL ; Total bilirubin (within normal institutional limits) AST (aspartate aminotransferase)/ALT (alanine aminotransferase) <2.5 X institutional upper limit of normal ; Creatinine (within normal institutional limits) ; EKG QTc < 450 msec (females)

7. No significant ocular disease: No prior known history of retinal neovascularization, macular edema or macular degeneration. Patients without such a history are required to have a baseline ophthalmologic exam as part of screening, and must not have evidence of retinal neovascularization, macular edema or macular degeneration on the screening exam in order to be eligible.

8. No other active cancer: Patients must be disease-free of prior invasive malignancies for > 2 years with the exception of curatively-treated basal cell or squamous cell carcinoma of the skin, carcinoma in situ of the cervix. Patient with the following prior or concurrent diagnoses are eligible: lobular carcinoma in situ, contralateral ductal carcinoma in situ, or contralateral invasive ductal and/or lobular carcinoma.
