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

22. Februar 2013 aktualisiert von: Bristol-Myers Squibb

A Randomized, Double-Blind, Multi-Center Phase II Trial of Exemestane (Aromasin®) Plus Dasatinib Versus Exemestane Plus Placebo in Advanced Estrogen Receptor-Positive Breast Cancer After Disease Progression on a Non-Steroidal Aromatase Inhibitor (NSAI)

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).
