AB  - Prolonged-release (PR) fampridine is approved to treat walking impairment in
      persons with multiple sclerosis (MS); however, treatment benefits may extend
      beyond walking. MOBILE was a phase 2, 24-week, double-blind, placebo-controlled
      exploratory study to assess the impact of 10mg PR-fampridine twice daily versus
      placebo on several subject-assessed measures. This analysis evaluated the
      physical and psychological health outcomes of subjects with progressing or
      relapsing MS from individual items of the Multiple Sclerosis Impact Scale
      (MSIS-29). PR-fampridine treatment (n=68) resulted in greater improvements from
      baseline in the MSIS-29 physical (PHYS) and psychological (PSYCH) impact
      subscales, with differences of 89% and 148% in mean score reduction from baseline
      (n=64) at week 24 versus placebo, respectively. MSIS-29 item analysis showed that
      a higher percentage of PR-fampridine subjects had mean improvements in 16/20 PHYS
      and 6/9 PSYCH items versus placebo after 24weeks. Post hoc analysis of the
      12-item Multiple Sclerosis Walking Scale (MSWS-12) improver population
      (>/=8-point mean improvement) demonstrated differences in mean reductions from
      baseline of 97% and 111% in PR-fampridine MSIS-29 PHYS and PSYCH subscales versus
      the overall placebo group over 24weeks. A higher percentage of MSWS-12 improvers 
      treated with PR-fampridine showed mean improvements in 20/20 PHYS and 8/9 PSYCH
      items versus placebo at 24weeks. In conclusion, PR-fampridine resulted in
      physical and psychological benefits versus placebo, sustained over 24weeks.
