Aims: (1) To illustrate a more comprehensive view of value associated with medicines treating highly severe illness. (2) To apply these insights to estimate the costs and benefits of three treatments for Multiple Sclerosis (MS): Avonex, Tysabri, and Tecfidera. Materials and Methods: Retrospective study spanning 2002-2013. We use economic theory to derive the value of therapy to those with and without MS, under the alternative assumptions that therapies were fully insured or paid for out of pocket. Models were parameterized through secondary data analysis and targeted literature review. Estimates of individual value were aggregated to the societal level using therapy-specific treatment prevalence rates. Aggregate consumer value was compared to manufacturer revenue. Results: In the baseline model, Avonex, Tysabri, and Tecfidera generated $46.2BN of total value to consumers, almost one-third of which accrued to those without MS. Total value to consumers was double manufacturer revenue. Results were qualitatively robust to the use of alternate epidemiological and economic parameters. We find that value to the healthy is positively related to disease severity, and that value to both the sick and the healthy are larger when costs are shared via health insurance. Conclusions: Theory predicts that treatments for severe disease provide “peace of mind” value to the healthy. Avonex, Tysabri, and Tecfidera have generated significant social value, a large majority of which accrues to consumers. Future economic valuations of medical technology should consider both the potential value to the healthy and the effects of insurance.
