Anastrozole Biphosphonate Study in Postmenopausal Women With Hormone-Receptor-Positive Early Breast Cancer (SABRE)

This study has been completed.
Information provided by:
AstraZeneca Identifier:
First received: May 5, 2004
Last updated: January 25, 2011
Last verified: January 2011
The purpose of this study is to evaluate safety parameters of anastrozole with regard to its potential effects on postmenopausal bone loss and on lipid profiles. This trial is conducted to investigate the effects of risedronate on BMD and on bone metabolism in postmenopausal women using anastrozole as adjuvant therapy for hormone-receptor-positive early breast cancer and who are high or moderate risk of fragility fracture. It is also conducted to determine the effects of anastrozole on bone mineral density (BMD) and on bone metabolism in women at low risk of fragility fracture.

Condition Intervention Phase
Breast Cancer Drug: Anastrozole Drug: Risedronate Sodium Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: A Multicentre Phase III/IV Study, of the Effects of Risedronate Sodium (ACTONEL™, 35mg/Week, Oral) on Bone, in Postmenopausal Women, With Hormone-receptor-positive Early Breast Cancer, Treated With Anastrozole (ARIMIDEX™, 1mg/Day Oral) With Risk of Fragility Fracture (High-risk Fragility Fracture-open-label, Non-comparative Stratum; Moderate-risk of Fragility Fracture-randomised, Double-blind Stratum; Low-risk of Fragility Fracture - Open-label, Non-comparative Stratum)Abbreviated
