Abstract
ATENA (Adjuvant post-Tamoxifen Exemestane versus Nothing Applied): a phase III randomized parallel-group multicenter trial, designed to compare 5 Years of adjuvant exemestane versus 5 years of observation in postmenopausal women with operable breast cancer who have received 5–7 years of adjuvant tamoxifen. The primary endpoint is disease-free survival. The effects of extended adjuvant therapy with exemestane on the lipid profile was a secondary endpoint. This trial was prematurely discontinued in November 2005 due to poor accrual following publication of the results of the MA.17 trial, which demonstrated a reduced risk of recurrence with extended adjuvant therapy using letrozole.
