Design outcomes

Primary

MeasureTime frame
Main Objective: •To evaluate the safety and toxicity of the TAC regimen with the addition of bevacizumab given as preoperative therapy to patients with Stage II or Stage III breast cancer •To estimate change from baseline expression of HIF1a as a measure of tumor angiogenesis, after a single dose of bevacizumab as compared to placebo ;Secondary Objective: •To estimate the rate of CHF in patients receiving TAC with or without bevacizumab •To estimate the rates of left ventricular ejection fraction (LVEF) changes as measured by either a decrease of > 15% from baseline, or > 10% to a value below the lower limit of normal (for the institution), in patients receiving TAC or TAC plus bevacizumab •To investigate the clinical efficacy of TAC and TAC plus bevacizumab by estimating the clinical objective response rate (CR + PR), pathologic complete response rate (pCR), and rate of breast-conserving surgery (BCS) •To estimate the rate of post-surgical wound healing complications in patients who receive surgery after TAC or TAC plus bevacizumab ;Primary end point(s): Efficacy Assessments Clinical •Clinical objective response rate (CR + PR) •Radiographic objective response rate by MRI (CR + PR) •Pathologic complete response rate (pCR) •Percentage of patients able to undergo breast-conserving surgery Molecular •Change in HIF-1a expression
