Study Summary

The purpose of this study is to determine whether exemestane plus dasatinib will be well-tolerated and will increase progression-free survival (PFS) in the treatment of advanced estrogen-receptor positive (ER+) breast cancer after disease progression (PD) on a non-steroidal aromatase inhibitor (NSAI).

Primary Outcome

PFS= The time (weeks) from date of randomization to date of progressive disease(PD). PFS for each randomization arm was estimated using the Kaplan-Meier product-limit method. A point estimate and a 95% confidence interval (CI) for the median PFS was computed for each randomization arm using the Brookmeyer \& Crowley method. PD=Increase (≥ 20%) in sum of longest diameters from smallest value during study (including baseline).
