KANSAS CITY, Mo.--(BUSINESS WIRE)--A comparison of the long-term economic outcomes of four immunomodulatory drug therapies combined with symptom management versus symptom management alone revealed that COPAXONE® (glatiramer acetate injection) was the most cost-effective treatment strategy for relapsing-remitting multiple sclerosis (RRMS). The study provides the first pharmacoeconomic evaluation of the cost-effectiveness of multiple sclerosis (MS) therapies that includes long-term treatment outcomes and costs associated with missed days from work. The study also evaluated the impact of neutralizing antibody (NAb) development in pharmacoeconomic measures among patients treated with the interferon beta (IFN-ß) class of drugs. The findings of the study, “Cost-effectiveness of Four Immunomodulatory Therapies for Relapsing-Remitting Multiple Sclerosis: A Markov Model Based on Long-term Clinical Data,” were published in the April issue of the Journal of Managed Care Pharmacy.
