Safety and Efficacy of Exemestane Plus Dasatinib Versus Placebo for Advanced ER+ Breast Cancer

Completed · Phase 2 · Has a placebo group

Conditions studied: Breast Cancer

In brief

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).
