Objective Peginterferon beta-1a 125 mcg, administered subcutaneously (SC) every 2 weeks, a new disease-modifying therapy (DMT) for relapsing-remitting multiple sclerosis (RRMS), was approved by the US Food and Drug Administration in 2014. This study assesses the cost-effectiveness of peginterferon beta-1a vs interferon beta-1a (44 mcg SC 3 times per week) and glatiramer acetate (20 mg SC once-daily) in the treatment of RRMS from the perspective of a US payer over 10 years. Methods A Markov cohort economic model was developed for this analysis. ⋯ Results were most sensitive to variations in the treatment effect of each DMT, treatment acquisition costs of each DMT and the time horizon. Probabilistic sensitivity analyses indicated that peginterferon beta-1a remains dominant in >90% of 5,000 replications compared with either DMTs. Conclusion This analysis suggests that long-term treatment with peginterferon beta-1a improves clinical outcomes at reduced costs compared with interferon beta-1a 44 mcg and glatiramer acetate 20 mg and should be a valuable addition to managed care formularies for treating patients with RRMS.

Background Dermatomyositis and polymyositis (DM/PM) are inflammatory myopathies characterized by muscle inflammation/weakness. Patients with DM/PM have a reduced quality-of-life and are at an increased risk for several comorbidities. Studies have assessed the incidence and prevalence of DM/PM; however, no study has estimated the burden of the diseases in terms of both healthcare resource utilization (HCRU) and work loss incurred by patients. ⋯ During the outcome period, DM/PM patients had significantly increased HCRU across places of service, including 44% more inpatient admissions (3.6 vs 2.5, p < 0.001), increased visits with specialists such as rheumatologists, neurologists and physical therapists, and filled 4.7 more prescriptions (32.2 vs 27.5, p < 0.001) than matched control patients. The increased HCRU led to significantly more medically-related work loss among DM/PM patients than matched controls (p < 0.001). Conclusions DM/PM imposes a substantial increase in healthcare resource use and is associated with statistically significantly greater work loss in the first year following diagnosis.
