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

2013년 2월 22일 업데이트: 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).

기간: Prior to study therapy, at 8 week intervals until progression occurs (maximum participant PFS of 71 weeks)
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.
