Cost-effectiveness analysis of infliximab, adalimumab, golimumab and vedolizumab for moderate to severe ulcerative colitis in Spain

ABSTRACTObjectives: Assess the efficiency of biologic treatment for moderate to severe ulcerative colitis (UC) which are indicated and financed for this pathology by Spain.Methods: A Markov model was constructed to simulate the progression in a cohort of patients with moderate to severe UC. The perspective chosen was National Health Service with an over 10 years of time horizon, with a discount rate of 3%, and established threshold of €30,000/quality-adjusted life-year (QALY).Results: The comparison between infliximab versus adalimumab achieved an incremental cost-effectiveness ratio (ICER) of €45,582/QALY, with a 0.900 QALYs difference of efficacy and an incremental cost of €41,036. Golimumab versus adalimumab reached an ICER of €2,175,992/QALY, with a difference of 0.001 QALY in efficacy and a raising cost to €2,611. The comparison between vedolizumab with adalimumab achieved an ICER of €90,532/QALY, 0.930 QALYs of difference and an increasing cost of €84,218. The probabilistic sensitivity analysis show...
