ABSTRACT
The use of gastro-resistant risedronate, a convenient dosing regimen for oral bisphosphonate therapy, seems a cost-effective strategy compared with weekly alendronate, generic risedronate, and no treatment for the treatment of postmenopausal women with osteoporosis in France. INTRODUCTION:
Gastro-resistant (GR) risedronate tablets are associated with improved persistence compared to common oral bisphosphonates but are slightly more expensive. This study assessed its cost-effectiveness compared to weekly alendronate and generic risedronate for the treatment of postmenopausal women with osteoporosis in France.METHODS:
A previously validated Markov microsimulation model was used to estimate the lifetime costs (expressed in 2017) per quality-adjusted life-years (QALY) of GR risedronate compared with weekly alendronate, generic risedronate, and no treatment. Pooled efficacy data for bisphosphonates derived from a previous meta-analysis were used for all treatment options, and persistence data (up to 3 years) were obtained from a large Australian longitudinal study. Evaluation was done for high-risk women 60-80 years of age, with a bone mineral density (BMD) T-score ≤ - 2.5 and/or prevalent vertebral fractures.RESULTS:
In all of the simulated populations, GR risedronate was cost-effective compared to alendronate, generic risedronate, and no treatment at a threshold of 60,000 per QALY gained. In women with a BMD T-score ≤ - 2.5 and prevalent vertebral fractures, the cost per QALY gained of GR risedronate compared to alendronate, generic risedronate, and no treatment falls below 20,000 per QALY gained. In women aged 75 years and older, GR risedronate was even shown to be dominant (more QALYs, less costs) compared to alendronate, generic risedronate, and no treatment.CONCLUSION:
This study provides the first economic results about GR risedronate, suggesting that it represents a cost-effective strategy compared with weekly alendronate and generic risedronate for the treatment of postmenopausal women with osteoporosis in France.Palabras clave
