Cost–consequence analysis of ofatumumab for the treatment of relapsing-remitting multiple sclerosis in Canada

Abstract

Aim: The costs and consequences of initial and delayed ofatumumab treatment were evaluated in relapsing-remitting multiple sclerosis with active disease in Canada. Materials & methods: A Markov cohort model was used (10-year horizon, annual cycle length, 1.5% discounting). Scenario analyses examined ofatumumab as first-line treatment versus 3 and 5 years following switch from commonly used first-line therapies. Results: Ofatumumab resulted in improvements in clinical outcomes (relapses and disease progression) and productivity (employment and full-time work), and reduction of economic burden (administration, monitoring and non-drug costs) that were comparable to other high-efficacy therapies (ocrelizumab, cladribine and natalizumab). Switching to ofatumumab earlier in the disease course may improve these outcomes. Conclusion: Results highlight the value of a high-efficacy therapy such as ofatumumab as initial treatment (i.e., first-line) in newly diagnosed relapsing-remitting multiple sclerosis patients with active disease.

Plain language summary

What is this article about?

Relapsing-remitting multiple sclerosis (RRMS) is the most common type of MS, an autoimmune disease that impacts the central nervous system, and is characterized by attacks (i.e., relapses) followed by complete or partial remissions. RRMS is associated with increased disability, costs, and reduced productivity due to disease progression. Early treatment with a high-efficacy therapy might improve outcomes and reduce costs. The study objective was to evaluate the costs and consequences of initial administration of the high-efficacy therapy ofatumumab, as well as after treatment with other commonly used first-line therapies, in patients with RRMS with active disease in Canada.

What were the results?

Ofatumumab resulted in improvements in clinical outcomes (relapses and disease progression) and productivity (employment and full-time work), and reduction of economic burden (administration, monitoring and non-drug costs) that were comparable to other high-efficacy therapies (ocrelizumab, cladribine and natalizumab). Switching to ofatumumab earlier in the disease course may improve these outcomes versus commonly administered first-line therapies.

What do the results of the study mean?

Results suggest that a high-efficacy therapy, like ofatumumab, would be a valuable early treatment option for patients with RRMS.
