A Partially Blind Phase III Randomised Trial of Faslodex +/- Concomitant Arimidex Compared With Exemestane in Post-menopausal Women With ER+ or PR+ Locally Advanced/Metastatic Breast Cancer Following Progression on Non-steroidal AIs

In Brief

A Phase 3 clinical trial evaluating Anastrozole, Exemestane, and 1 other intervention for Breast Cancer. Completed, enrolled 698 participants across 2 sites.

Detailed Summary

RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using fulvestrant, anastrozole, or exemestane may fight breast cancer by blocking the use of estrogen by the tumor cells or by lowering the amount of estrogen the body makes. It is not yet known whether giving fulvestrant together with anastrozole is more effective than giving fulvestrant together with a placebo or exemestane alone in treating breast cancer. PURPOSE: This randomized phase III trial is studying fulvestrant and anastrozole to see how well they work compared to fulvestrant and a placebo or exemestane alone in treating postmenopausal women with locally advanced or metastatic breast cancer.
