Objectives: Emerging evidence supports sequential therapy with anabolic followed by antiresorptive in patients at high-risk of fragility fractures. This study assessed the cost-effectiveness of sequential treatment with abaloparatide (ABL) followed by alendronate (ALN) [(ABL/ALN)] compared to ALN monotherapy and to sequential treatment starting with antiresorptive therapy (ALN/ABL/ALN).
Methods: A previously validated Markov microsimulation model was used to estimate the cost-effectiveness of sequential ABL/ALN compared to ALN monotherapy and to sequential ALN/ABL/ALN from a lifetime US payer perspective. In line with practice guidelines, patients were assumed to receive ABL for 18 months followed by 5 years of ALN, or ALN monotherapy for 5 years, or a sequence of ALN for 2 years followed by 18 months of ABL and then by 3 years ALN. Evaluation was conducted for patients aged 50-80 years old with a BMD T-score = 1 osteoporotic fracture.
Results: Sequential ABL/ALN was cost-effective (threshold of US$150,000 per QALY) vs generic ALN monotherapy in women >= 60 years with a BMD T-score
Conclusions: Sequential ABL/ALN therapy is cost-effective vs ALN monotherapy for US postmenopausal women aged >= 60 years at increased risk of fractures. (C) 2020 The Author(s). Published by Elsevier Inc.
