Objectives
There are increasingly effective therapies for relapsing forms of multiple sclerosis (MS); however, the options for the progressive patient population are limited. The effect of mycophenolate mofetil (MMF), a disease-modifying agent for several autoimmune diseases, in progressive MS has not been explored effectively. We performed a prospective study to assess the safety and efficacy of MMF in progressive MS patients.
Methods
We identified 64 patients enrolled in the comprehensive longitudinal database at the Partners MS Center, who fulfilled our inclusion criteria. They were exposed to MMF for at least 1 year with recorded clinical outcomes. Efficacy was assessed by comparing the absolute relapse rate (ARR), and the mean Expanded Disability Status Scale (EDSS) and timed 25 foot walk (T25FW) test scores before and after MMF treatment.
Results
At the start of MMF, 78% of patients (n = 50) were in the 4–7.5 EDSS range. There was a slight increase in mean EDSS from 5.49 ± 1.65 (n = 48) 1 year before MMF start to 5.85 ± 1.56 (n = 48) 1 year after (p = 0.020). The mean T25FW score increased 1 year before MMF from 12.3 ± 9.6 s (n = 38) to 15.6 ± 12.3 s (n = 38) 1 year after (p = 0.009). The ARR in the 2 years pre-MMF period was 0.30 ± 0.63, which decreased to a 0.09 ± 0.29 (p = 0.022) 2 years post MMF.
Conclusion
MMF did not affect disease progression but did influence relapse rate. We believe that other medication options should be considered before MMF in advanced progressive patients.
