Cost-Utility Analysis of VEGF Inhibitors for Treating Neovascular Age-Related Macular Degeneration.

Abstract：

PURPOSE:To perform 11- and 2-year health care sector (ophthalmic) and societal cost perspective reference case, cost-utility analyses comparing bevacizumab, ranibizumab, and aflibercept monotherapies for neovascular age-related macular degeneration (NVAMD). DESIGN:Cost-utility analysis. METHODS:The authors performed 11-year and 2-year ophthalmic and societal cost perspective, cost-utility analyses comparing bevacizumab, ranibizumab, and aflibercept monotherapies for neovascular age-related macular degeneration (NVAMD). We employed patient utilities, bilateral outcomes, 2018 U.S. dollars, vision-related mortality, a Medicare fee schedule, and CATT (Comparison of Age-Related Macular Degeneration Treatments) study and VIEW (VEGF Trap-Eye: Investigation of Efficacy and Safety in Wet AMD) trial. Cochrane data were also used. SETTING:Center for Value-Based Medicine. Patient/study population: patients with NVAMD. INTERVENTION:Cost-utility analyses using published data. Data-modeled 10-year vision outcomes were modeled forward to year 11. MAIN OUTCOME MEASUREMENT:These included cost-utility ratios (CURs), costs, and quality-adjusted life-years (QALYs) gained. $100,00/QALY was considered the US cost-effectiveness upper limit. RESULTS:Bevacizumab and ranibizumab each conferred an 11-year, 1.339 QALY gain versus observation. Aflibercept conferred a 1.380 QALY gain. Aflibercept conferred greater QALY gain for less cost than ranibizumab but was not cost-effective compared to bevacizumab ($1,151,451/QALY incremental CUR). The average ophthalmic cost perspective CUR for bevacizumab was $11,033/QALY, $79,600/QALY for ranibizumab, and $44,801/QALY for aflibercept. Eleven-year therapies saved a 1.0 year-of-life loss without treatment from the 11.0-year life expectancy. Early treatment was 138%-149% more cost-effective than late treatment. Two-year therapy prevented a 1-month-of-life loss, and revealed bevacizumab, ranibizumab, and aflibercept conferred 0.141, 0.141, and 0.164 QALY gains, respectively, with corresponding average CURs of $40,371/QALY, $335,726/QALY, and $168,006/QALY, respectively. CONCLUSIONS:From an ophthalmic (medical) cost perspective, bevacizumab, ranibizumab, and aflibercept NVAMD monotherapies were all cost-effective over 11 years, with bevacizumab 6.21× more cost-effective than ranibizumab and 3.06× more cost-effective than aflibercept. Two-year modeling revealed bevacizumab was cost-effective, whereas ranibizumab and aflibercept were not. Early treatment was critical for obtaining optimal vision and cost-effectiveness, as is long-term follow-up and adherence to treatment.
