Preliminary study delivers promising results
This study of 12 HSPers in France resulted in half of them showing significant improvement in walking speed and gait mechanics, and half without. They all received 10mg/twice a day dalfampridine (known in Australia as Fampyra and used with Multiple Sclerosis) for 2 weeks. While these are promising results, it was not a clinical trial, but suggests that one to fully test the drug for use with HSP is called for.
Our aim was to support the use of dalfampridine as a treatment for patients affected with hereditary spastic paraplegia (HSP). We performed a prospective, uncontrolled, proof of concept, open trial. We included 12 HSP patients defining the total group (TG) who received dalfampridine 10 mg twice daily for 2 weeks.
Efficacy assessment was based on walking ability improvement. The Timed-25-Foot Walk Test, the Spastic Paraplegia Rating Scale (SPRS), and the 12-item Multiple Sclerosis Walking Scale (MSWS-12) were performed before and after treatment. Safety assessment was based on adverse events occurrence.
A significant improvement in SPRS (p = 0.0195) and MSWS-12 (p = 0.0429) was noted after treatment in the TG. No serious adverse events were noted. This interventional study provides encouraging results supporting the use of dalfampridine in HSP.
