Abstract

Summary

The ROSE study compared annual infusion with zoledronic acid and weekly generic alendronate. No significant differences in quality of life or health status between treatment groups were observed. Adherence to alendronate during the study was high, with 80.9% of patients achieving adequate adherence.

Introduction

A secondary analysis to evaluate quality of life, health status, adherence to alendronate and therapy preference in postmenopausal women with low bone mass who received treatment with zoledronic acid or alendronate was conducted.

Methods

Postmenopausal women with low bone mass were randomised 2:1 to receive an annual infusion of zoledronic acid or weekly oral generic alendronate in this open-label, multicentre study. Changes in quality of life and health status were assessed using questionnaires at baseline and month 12. Adherence to alendronate was assessed by the investigator and/or study personnel, and subjective therapy preference was assessed using a questionnaire at month 12.

Results

Patients were randomised to zoledronic acid (n = 408) and alendronate (n = 191). Overall, there were no significant differences in quality of life between zoledronic acid and alendronate. However, improvements in quality of life with zoledronic acid versus alendronate could be detected by posthoc analysis in patients with previous fractures. There were no significant differences in health status between patients receiving zoledronic acid or alendronate. Adherence to alendronate during the study was high, with 80.9% of patients achieving adequate adherence. A total of 81% of patients who had received zoledronic acid indicated that they would prefer to continue with that treatment, and 43% of the patients who received oral alendronate would like to switch to zoledronic acid.

Conclusions

There were no significant differences in quality of life between patients receiving zoledronic acid or alendronate.
