Pharmacoeconomic study of tocilizumab dosing strategies as an intravenous solution in rheumatoid arthritis

Type: article
Abstract: Tocilizumab (TCZ) is widely used in rheumatoid arthritis (RA) and may be administered using different dosing regimens, including the standard dose (SD) of 8 mg/kg and regimens involving dose reduction or escalation depending on the clinical response. Under current healthcare conditions, assessment of the clinical and economic feasibility of drug-dosing strategies is particularly relevant. Objective : to evaluate, from the perspective of the Russian healthcare system, the clinical and economic feasibility of a TCZ dose de-escalation strategy (DDS) from 8 to 4 mg/kg after remission is achieved and a dose escalation strategy (DES) from 4 to 8 mg/kg if remission is not achieved, compared with the SD of 8 mg/kg in patients with RA. Material and methods . A decision-tree model with 1and 3-year time horizons was developed to compare the three TCZ dosing strategies. Costminimization analysis, budget impact analysis, and one-way sensitivity analysis were performed. Results and discussion . Over a 1-year time horizon, DES provided savings of 169,850 rubles (28.1%) per patient compared with SD, whereas DDS provided savings of 58,188 rubles (9.6%). Over a 3-year time horizon, savings amounted to 168,849 rubles (10.3%) and 95,848 rubles (5.8%) for DES and DDS, respectively. According to the budget impact analysis, transferring a proportion of patients to DES could reduce costs by 1.0–1.7 billion rubles over 3 years, whereas transition to DDS could reduce costs by 0.6–1.0 billion rubles. Conclusion . Within the adopted assumptions, the model demonstrates a potential reduction in direct drug costs when using strategies involving controlled dose reduction or initiation at a lower dose followed by escalation. Owing to the limited availability of direct comparative data and regulatory restrictions in the Russian Federation, the results should be regarded as a scenario-based pharmacoeconomic assessment requiring validation using Russian data.
