Randomized Phase III Study of Exemestane (Aromasin) for 5 Years Versus Tamoxifen for 2.5 to 3 Years Followed by Exemestane - Full Text View

Purpose

To compare the effects of exemestane for 5 years versus tamoxifen and exemestane given sequentially over 5 years in the adjuvant treatment of postmenopausal women with early breast cancer.

This Pfizer sponsored trial is part of an international collaboration of investigators conducting 7 similar yet independent studies in 9 countries. This study is designed to be part of the larger TEAM trial where the data from these 7 studies will be combined. A pre-specified analysis of the pooled data will be conducted.

Official Title:	Randomized Phase III Study of Exemestane (Aromasin) for 5 Years Versus Tamoxifen for 2.5- 3 Years Followed by Exemestane (Aromasin) for a Total of 5 Years as Adjuvant Therapy for Postmenopausal, Receptor Positive, Node Negative or Node Positive Breast Cancer Patients

Further study details as provided by Pfizer:

Primary Outcome Measures:

To determine whether adjuvant treatment with exemestane improves the disease-free survival of postmenopausal, receptor positive, node negative or node positive breast cancer patients compared with adjuvant tamoxifen therapy at 2.75 and 5 years. [ Time Frame: 2.75 years; 5 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Overall survival [ Time Frame: 5 years ] [ Designated as safety issue: No ]
The incidence of new primary breast cancers of the postmenopausal women treated with 5 years of exemestane (Aromasin) versus tamoxifen therapy for 2.5- 3 years followed by 2.5- 2 years of exemestane (Aromasin). [ Time Frame: 2.75 years; 5 years ] [ Designated as safety issue: No ]
The relative safety profiles [ Time Frame: 2.75 years; 5 years ] [ Designated as safety issue: No ]

Estimated Enrollment:	9300
Study Start Date:	October 2001
