Anastrozole Biphosphonate Study in Postmenopausal Women With Hormone-Receptor-Positive Early Breast Cancer - Full Text View

Sponsored by:	AstraZeneca
Information provided by:	AstraZeneca
ClinicalTrials.gov Identifier:	NCT00082277

Purpose

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.

Study Design:	Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator), Placebo Control, Parallel Assignment, Safety/Efficacy Study
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
