Evaluating cost per remission and cost of serious adverse events of advanced therapies for ulcerative colitis

Assessing the economics of biologic and small molecule therapies for the treatment of moderate to severe ulcerative colitis in Japan: a cost per responder analysis of upadacitinib

AIM

Patients with moderately to severely active ulcerative colitis have an increasing number of advanced therapy options including several biologics and Janus kinase inhibitors. Though data on efficacy and safety of these advanced therapies are available, less is known about the potential economic implications of their utilization in Japan. We evaluated the relative value of these advanced therapies in Japan using a locally developed cost per responder model.

METHODS

A model was developed using relevant clinical endpoints and treatment costs to calculate cost per responder of all advanced therapies used for moderately to severely active ulcerative colitis treatment in Japan. Cost per responder was assessed in biologic-naïve and biologic-exposed populations, respectively. The model incorporated induction and maintenance therapy pathways as patients progressed through based on efficacy rates (clinical response, clinical remission and endoscopic improvement). Total costs for induction and maintenance included: drug acquisition, drug administration and serious adverse event management (as necessary) for responders, with additional rescue treatment cost only for non-responders.

RESULTS

Upadacitinib showed lower cost per clinical response and cost per clinical remission across both biologic-naïve and biologic-exposed populations with only one exemption in cost per clinical remission in biologic-naïve population. In addition, upadacitinib demonstrated lower cost per endoscopic improvement in both populations. Janus kinase inhibitors outperformed with lower cost per responder than other mediations across all outcomes and patient populations with the exception of tofacitinib for clinical remission in biologic-exposed UC population.

LIMITATIONS

Comparative data used in this analysis have been derived from network meta-analysis, not from direct comparison.

CONCLUSIONS

The results of this cost per responder analysis suggest upadacitinib is a cost-effective option for the first- and second-line treatment of moderately to severely active ulcerative colitis in Japan.

Lack of Benefit for Early Escalation to Advanced Therapies in Ulcerative Colitis: Critical Appraisal of Current Evidence

Although ulcerative colitis [UC] shares many common pathways and therapeutic options with Crohn's disease [CD], CD patients are four times more likely to undergo surgery 10 years into their disease in the biological era and are more likely to have extraintestinal manifestations than UC patients. Early treatment in CD has been demonstrated to modify the natural history of the disease and potentially delay surgery. Previous reviews on this topic have borrowed their evidence from CD to make UC-specific recommendations. This review highlights the emergence of UC-specific data from larger cohort studies and a comprehensive individual patient data systemic review and meta-analysis to critically appraise evidence on the utility of early escalation to advanced therapies with respect to short-, medium-, and long-term outcomes. In UC, the utility of the early escalation concept for the purposes of changing the natural history, including reducing colectomy and hospitalizations, is not supported by the available data. Data on targeting clinical, biochemical, endoscopic, and histological outcomes are needed to demonstrate that they are meaningful with regard to achieving reductions in hospitalization and surgery, improving quality of life, and minimizing disability. Analyses of different populations of UC patients, such as those with 'relapsing & remitting' disease or with severe or complicated disease course, are urgently needed. The costs and risk/benefit profile of some of the newer advanced therapies should be carefully considered. In this clinical landscape, it appears premature to advocate an indiscriminate 'one size fits all' approach to escalating to advanced therapies early during the course of UC.
