Metronomic Low-Dose Cyclophosphamide and Methotrexate With or Without Bevacizumab in Treating Women With Metastatic Breast Cancer

Completed · Phase 2

Conditions studied: Breast Cancer

In brief

This randomized phase II trial is studying metronomic low-dose cyclophosphamide and methotrexate to see how well they work compared to metronomic low-dose cyclophosphamide, methotrexate, and bevacizumab in treating women with metastatic breast cancer.

You may qualify if…

• Patients must have histologically or cytologically confirmed invasive breast cancer, with stage IV disease. Patients without pathologic or cytologic confirmation of metastatic disease should have unequivocal evidence of metastasis by physical exam or radiologic study.
• Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥ 20 mm with conventional techniques or as ≥ 10 mm with spiral CT scan. The protocol will employ the RECIST criteria.
• Prior Therapy:
• Chemotherapy: early stage breast cancer. Patients may have received prior adjuvant chemotherapy and/or hormonal therapy for early stage breast cancer, including cyclophosphamide-based chemotherapy regimens.
• Chemotherapy: metastatic breast cancer. Patients may have received 0-1 prior regimens for metastatic breast cancer. No prior oral cyclophosphamideor methotrexate-based therapy for metastatic disease is permitted.
• Chemotherapy: anthracyclines. Patients without prior anthraycline (in either the metastatic or adjuvant setting) exposure are eligible provided that they do not have visceral (parenchymal lung or liver) metastases. Patients without prior anthracycline-based therapy are expected to have "low volume" tumor burden, deemed appropriate for non-standard chemotherapy in the estimation of the treating clinician.
• Trastuzumab. Patients with HER2-positive breast tumors must have received prior trastuzumab therapy for advanced disease, or have had recurrence within 12 months of receiving (neo)adjuvant trastuzumab.
• Radiation therapy. Patients may have received prior radiation therapy in either the metastatic or early stage settings. Radiation therapy may not be administered during the study. Lesions progressing after previous irradiation are measurable; lesions not progressing after previous irradiation are not measurable.
• Hormonal therapy. Patients with estrogen- or progesterone-receptor positive disease must have received at least one prior hormonal therapy in the adjuvant and/or metastatic setting.
• -- Patients must discontinue chemotherapy and/or hormonal therapy prior to study participation.
• Concurrent Therapy. Patients may receive concurrent bisphosphonate therapy and/or erythropoietin growth factor support while on study. Patients may not receive other experimental treatments while on study. Bisphosphonate therapy and/or erythropoietin growth factor support therapy may commence at any point on study.
• Patients may not have received prior experimental angiogenesis inhibitors.
• Age ≥18 years.
• Life expectancy greater than 6 months.
• ECOG performance status ≤ 1 (Karnofsky ≥70%; see Appendix B).
• Absence of poorly controlled hypertension (as defined by the treating clinician), proteinuria, prior history of either deep venous or arterial thrombosis, bleeding diatheses (including hemoptysis).
• Radiologic exclusion of brain metastases (because of concern for potential CNS bleeding with therapy). All patients must have a brain CT or MRI no more than 6 weeks prior to enrollment.
• Left ventricular function ≥ 45% as assessed by echocardiogram or nuclear medicine gated study.
• Patients must have normal organ and marrow function as defined below. Labs should be completed within 4 weeks prior to registration.
• absolute neutrophil count ≥1000/mm3
• platelets ≥100,000/mm3
• total bilirubin ≤ 2 x institutional upper limit of normal (ULN)
• AST(SGOT)/ALT(SGPT) ≤ 4.0 x ULN
• Alkaline phosphatase ≤ 5.0 x ULN
• creatinine ≤ 2.0 mg/dl
