First Line Metastatic Breast Cancer Treatment (ESMERALDA)

Number of patient with non progressive disease

The principal endpoint is to determine the disease control rate (or rate of non-progression) at one year in patients with metastatic breast cancer treated in the first line setting by a combination of eribulin/bevacizumab. In this open-label trial, the sample size is calculated based on Simon's two-stage design, used to test whether the disease control rate at one year will be at least 50%, a clinically promising rate, versus a rate of 33%, a rate that is not clinically promising. Considering a type I risk (alpha) error of 5%, with 54 patients, this study has an 80% power to detect a disease control rate at one year of 50%.
