- W2337702988 abstract "Background: The North American Research Committee on Multiple Sclerosis Registry (NARCOMS) captures self-reported disease modifying therapy (DMT) information and patient-reported outcomes from persons with MS. Previous reports show that those who remain on the same DMT report less disease worsening than those who switch.Objective: Assess characteristics of persons with MS who switch from an parenteral DMT [interferon beta (-1a IM, -1a SC, -1b), glatiramer acetate, natalizumab] to an oral DMT [dimethyl fumarate (DMF), fingolimod (FIN), teriflunomide (TF)].Methods: US residents who reported a switch from a parenteral DMT to an oral DMT in Spring or Fall survey in 2011-2013 were included in the analysis. Switching to DMF/TF was not captured until Fall 2012. We compared socio-demographic factors, Patient Determined Disease Steps (PDDS) as a measure of disability, and relapse activity as reported at the time of the switch and 6 months later. Results are reported as mean (SD), median (IQR) or [percnt], as applicable.Results: 595 registry participants indicated switching to FIN (n=278), DMF (n=238) or TF (n=79) from a parenteral DMT from 2011-2013. Switchers were 81.7[percnt] female, 51.6(9.8) years old, with mean disease duration of 14.6(8.4) years and 97.9[percnt] had health insurance. Median PDDS of switchers was 3(1, 5), with only 16.8[percnt] reporting PDDS worsening of at least 1 point as compared to 6 months before the switch. Relapse during the 6 months before the switch was reported by 26.1[percnt] and symptom worsening by 35.0[percnt] of the switchers, while 4.7[percnt] (23/486) reported a relapse in the prior 6 months.Conclusion: Follow-up on those taking the oral DMTs provides important information on switching behavior. Most participants that switched reported worsening in PDDS, symptom worsening, and/or switched following relapses. Patient-reported outcomes provide a practical way of describing disease activity and comparing switchers with those remaining on an established DMT.
