Brief Summary:
Our hypothesis is that this study design in which bevacizumab is added to one of six single agent chemotherapies with proven activity in metastatic breast cancer will result in regression or stabilization of this disease in a safe and tolerable manner
Detailed Description:
There is an unmet clinical need for effective therapy of breast cancer that has metastasized to the brain In this scenario median survival is around 12 months using currently available therapeutic interventions The majority of chemotherapy-based clinical trials have considered the presence of central nervous system metastasis an exclusion criterion due to the risk of toxicities the inability of chemotherapeutic agents to cross the blood brain barrier and the limited overall survival within this patient population
The preclinical data regarding the safety and activity of bevacizumab in vascular endothelial growth factorVEGF-expressing tumors provide a good rationale for its study in patients with breast cancer with metastasis to the brain Yano et al illustrated that tumor cell expression of VEGF messenger ribonucleic acid and protein directly correlated with angiogenesis and growth of brain metastasis in a nude mouse model Transfecting the experimental cell lines known to produce visceral metastasis with an anti-sense VEGF-gene significantly reduced the incidence of brain metastasis Kim et al illustrated that a murine model specific for brain metastases originating from breast cancer showed elevated expression of the angiogenic and permeability-inducing factor VEGF-A The growth of the brain metastases in this model was attenuated by the addition of a VEGF-tyrosine kinase inhibitor via induction of apoptosis and decreased angiogenesis VEGF has also been implicated in the development of brain edema a significant source of the morbidity and mortality associated with brain metastasis Enhanced levels of VEGF and its receptors have been reported in a murine model after induction of cortical ischemia Finally antagonism of VEGF was demonstrated to reduce both immediate and delayed volume of infarct
The optimal dose of bevacizumab has been extensively studied in phase I trials alone and in combination with chemotherapy The safe and effective dose has been established as 10 mgkg q 14 days or 15 mgkg Q 21 days In addition to irinotecan and paclitaxel it has been previously used in phase IIIII settings in combination with capecitabine vinorelbine gemcitabine and docetaxel Phase III studies showed an overall survival advantage when bevacizumab was added to an irinotecanFluorouracil 5FU-based regimen for metastatic colorectal cancer and when added to weekly paclitaxel for metastatic breast cancer
