Drug survival of anti-TNF agents compared with vedolizumab as a second-line biological treatment in inflammatory bowel disease: results from nationwide Swedish registers.

ABSTRACT:

Background

Comparisons of second-line anti-tumour necrosis factor (TNF) agents and vedolizumab are sparse.

Aim

To evaluate the effectiveness of anti-TNF agents compared to vedolizumab as second-line biologics in inflammatory bowel disease (IBD).

Methods

A propensity score-matched cohort was created using Swedish nationwide registers. Patients with Crohn's disease or ulcerative colitis, exposed to first-line anti-TNF treatment, who initiated a second anti-TNF agent or vedolizumab in 2014-2016 (N = 1363) were included. The primary outcome was drug survival at 12 months. Secondarily, we assessed survival without IBD-related hospitalisation, IBD-related surgery, antibiotics, or hospitalisation because of infection, and also corticosteroid exposure.

Results

After 1:1 propensity score matching, 400 patients (Crohn's disease, N = 198; ulcerative colitis, N = 202) remained. For Crohn's disease, drug survival was 73% in the vedolizumab group vs 74% in the anti-TNF group (difference: 1 percentage point; 95% confidence interval [CI]:-11-13; P = 0.87). Survival without IBD-related hospitalisation (82% vs 88%), surgery (82% vs 89%), antibiotics (65% vs 71%), hospitalisation due to infection (95% vs 88%) and corticosteroids (58% vs 48%) were not statistically significantly different between groups. For ulcerative colitis, drug survival was 69% in the vedolizumab group vs 62% in the anti-TNF group (difference: -7 percentage points; 95% CI: -20 to 6; P = 0.30). Vedolizumab-treated patients had lower survival without IBD-related hospitalisation (82% vs 93%, P = 0.02). Survival without colectomy (93% vs 97%), antibiotics (81% vs 70%), hospitalisation due to infection (92% vs 92%) and corticosteroids (58% vs 48%) were not statistically significantly different.

Conclusions

Based on Swedish clinical practice, the effectiveness and safety of second-line anti-TNF and vedolizumab at 12 months appeared largely similar.

Project description:ObjectivesThe objective of this study was to evaluate the cost-effectiveness of abatacept, tocilizumab, and tumor necrosis factor (TNF) inhibitors as compared with rituximab in Finnish rheumatoid arthritis patients, who have previously been treated with TNF inhibitors.MethodsA patient-level simulation model was developed to predict costs and outcomes associated with four biological drugs (abatacept, tocilizumab, rituximab and TNF inhibitors) in the treatment of rheumatoid arthritis. Following lack of efficacy or adverse events, the patients were switched to another biological drug until all four options were exhausted. After that, the patients were assumed to receive a 6th line treatment until death. The patients' baseline characteristics and regression models used in the simulation were based on observational data from the National Register for Biological Treatments in Finland. Direct costs comprised drug costs, administration costs, costs of switching, and outpatient and inpatient care, while indirect costs included disability pension and sick leaves due to rheumatoid arthritis. Several subgroup and deterministic sensitivity analyses were conducted.ResultsDrug costs were the lowest for rituximab, but when administration costs and costs of switching were included, drug costs were the lowest for TNF inhibitors. Abatacept was associated with the highest drug costs, whereas rituximab was associated with the highest healthcare costs. In total, TNF inhibitors had the lowest direct costs, while rituximab had the highest direct costs. The amount of quality-adjusted life years (QALY) gained ranged from 9.405 for rituximab to 9.661 for TNF inhibitors. TNF inhibitors, abatacept, and tocilizumab were dominant in comparison to RTX.ConclusionsTNF inhibitors, abatacept, and tocilizumab had lower costs and higher QALYs than rituximab, and therefore, they were dominant in comparison to rituximab. As TNF inhibitors had the lowest costs and highest QALYs, they were the most cost-effective treatment option.

Project description:BACKGROUND:Vedolizumab (VDZ) was approved by the Japanese Ministry of Health, Labor and Welfare in 2018 for the treatment of patients with moderate-to-severe active ulcerative colitis (UC). The comparative cost-effectiveness of VDZ compared with other biologics is unknown in Japan. This information could be useful for decision makers at the time of repricing biologics for the treatment of patients with moderate-to-severe UC. OBJECTIVE:The aim was to assess the cost-effectiveness of VDZ versus other branded biologics for the treatment of patients with moderate-to-severe UC who were anti-tumor necrosis factor (TNF)-naïve, from the Japanese public healthcare payer perspective. METHODS:A hybrid decision tree/Markov model was developed to predict the number of patients who achieved response and remission at the end of the induction phase and sustained it during the maintenance phase, translating this into quality-adjusted life-years (QALYs) and costs. Treatment-related adverse events, discontinuation and surgery, and their impact on QALYs and costs were also modeled. A systematic literature review and network meta-analysis were conducted to estimate the comparative efficacy of each treatment versus placebo. Rates of adverse events, surgery, surgery complications, and utilities were from the literature. Costs (2018 Japanese yen) were obtained from the Japanese National Health Insurance drug price list and medical fee table and local claims databases. Clinical and economic outcomes were projected over a lifetime and discounted at 2% annually. RESULTS:Over a lifetime, VDZ yielded greater QALYs and cost savings compared with golimumab and was cost-effective compared with adalimumab and infliximab (incremental cost-effectiveness ratios ¥4,821,940 and ¥4,687,692, respectively). Deterministic and probabilistic analyses supported the robustness of the findings in the base-case analysis, indicating that VDZ was either dominant or cost-effective in most scenarios and replications. The main limitations of this analysis include excluding tofacitinib and infliximab biosimilar as comparators, health-state utility estimates were obtained from population studies in the United Kingdom, and the impact of subsequent (i.e., second-line) biologic treatment was not evaluated. CONCLUSION:Our analysis suggests that VDZ is dominant or cost-effective compared with other branded biologics for the treatment of anti-TNF-naïve patients with moderate-to-severe UC in Japan.
