Cost-Effectiveness Analysis of 1-Year Treatment with Golimumab/Standard Care and Standard Care Alone for Ulcerative Colitis in Poland

Objective: The objective of this study was to assess the cost-effectiveness of induction and maintenance treatment up to 1 year of ulcerative colitis with golimumab/standard care and standard care alone in Poland. Methods: A Markov model was used to estimate the expected costs and effects of golimumab/standard care and a standard care alone. For each treatment option the costs and quality adjusted life years were calculated to estimate the incremental cost-utility ratio. The analysis was performed from the perspective of the Polish public payer and society over a 30-years time horizon. The clinical parameters were derived mainly from the PURSUIT-SC and PURSUIT-M clinical trials. Different direct and indirect costs and utility values were assigned to the various model health states. Results: The treatment of ulcerative colitis patients with golimumab/standard care instead of a standard care alone resulted in 0.122 additional years of life with full health. The treatment with golimumab/standard care was found to be more expensive than treatment with the standard care alone from the public payer perspective and from social perspective. The incremental cost-utility ratio of golimumab/standard care compared to the standard care alone is estimated to be 391,252 PLN/QALY gained (93,155 €/QALYG) from public payer perspective and 374,377 PLN/QALY gained (89,137 €/QALYG) from social perspective. Conclusions: The biologic treatment of ulcerative colitis patients with golimumab/standard care is more effective but also more costly compared with standard care alone.
