A comprehensive cost-effectiveness analysis of treatments for multiple sclerosis.
The purpose of this study was to examine the cost-effectiveness of four disease-modifying drugs (DMDs) used to treat multiple sclerosis (MS): glatiramer acetate (GA; Copaxone), interferon beta-1a (IFNβ-1a) intramuscular (IM) injection (Avonex), IFNβ-1a subcutaneous (SC) injection (Rebif), and interferon beta-1b (IFNβ-1b) SC injection (Betaseron). Cost-effectiveness analyses are useful in countering the financial uncertainties and treatment efficacy concerns faced by people with MS. We conducted simulation analyses of the principal findings of a 2009 study by Goldberg et al. (Goldberg LD, Edwards NC, Fincher C, et al: Comparing the cost-effectiveness of disease-modifying drugs for the first-line treatment of relapsing remitting multiple sclerosis. J Manag Care Pharm. 2009;15:543-555) to frame the researchers' findings from the perspectives of cost-conscious and cost-neutral MS patients. We found that for the cost-conscious consumer, the ranking of most (1) to least (4) preferred DMDs was 1) IFNβ -1a IM (Avonex), 2) GA (Copaxone), 3) IFNβ-1a SC (Rebif), and 4) IFNβ-1b SC (Beta-seron). For the cost-neutral consumer who places priority on effectiveness over costs, the ranking was 1) IFNβ-1a SC (Rebif), 2) IFNβ-1b SC (Betaseron), 3) GA (Copaxone), and 4) IFNβ-1a IM (Avonex). Future studies could examine cost-effectiveness over extended periods of time (eg, 15-20 years) and more closely examine the cost-effectiveness of natalizumab (Tysabri) relative to the four primary DMDs.
