BackgroundKnowledge regarding the economic outcomes of anti-tumour necrosis factor-α (anti-TNFα) and oral Janus kinase inhibitor (JAKi) therapies for the treatment of ulcerative colitis (UC) is limited. We conducted this analysis to assess the economic outcomes of anti-TNFα, antiadhesion molecule inhibitors (anti-AMi), and oral JAKi therapies for the treatment of UC from the perspectives of the United Kingdom (UK) and China, which are the representatives of high-income and middle-income regions, respectively.MethodsA Markov model-based economic analysis was performed by incorporating effectiveness and utility data obtained from the literature and costs based on publicly available reports. The UK and Chinese health care perspectives were adopted to evaluate different intervention treatment sequences, including 14 treatment sequences consisting of conventional therapy, tofacitinib, adalimumab, vedolizumab, golimumab, and infliximab. The participants were the patients with moderate-to-severe UC eligible for anti-TNFα, anti-Ami, and JAKi treatment. Cost, quality-adjusted life years (QALYs), and the incremental cost-effectiveness ratio (ICER) were reported.ResultsCompared to other alternatives comprising adalimumab, golimumab, and infliximab, the use of a treatment sequence comprising tofacitinib and vedolizumab always had better health outcomes. The most cost-effective options in the UK included the sequences comprising tofacitinib and vedolizumab, and the most cost-effective treatment option in China was tofacitinib. There were uncertainties surrounding the results, the key drivers of which being the utility values, effectiveness of conventional therapy, and relative efficacy of the active treatments.ConclusionsThe treatment with tofacitinib and vedolizumab for moderate-to-severe UC is likely to be the most favorable cost-effective option in the high-income UK, and tofacitinib is the most cost-effective option in the middle-income China.
