Low clinical benefit in the management of walking disorders in multiple sclerosis patients


  • FAMPYRA has been granted a marketing authorisation for the improvement in walking ability of patients suffering from multiple sclerosis (MS) and presenting with a walking handicap (EDSS 4-7).

  • The data derived from a new phase III study have confirmed its modest efficacy versus placebo on walking ability, along with the existence of a small fraction of responders that cannot be identified beforehand.

  • Its tolerance profile is marked by high, though relatively infrequent risks of convulsions, severe hypersensitivity and urinary tract infection.

  • It failed to improve the quality of life of the patients in the clinical studies.
