General information about the trial
|
|||
Main objective of the trial |
The primary objective of the study is to assess the effect of treatment with prolonged-release fampridine 10 mg twice, on the quantified gait analysis parameters (kinematics, dynamics, mechanical work).
|
||
Protection of trial subjects |
All observed adverse events regardless of treatment group or suspected relationship to the IP were reported.
|
||
Background therapy |
Patients meeting the inclusion criteria first underwent a 4-week run-in period during which they were treated by 10 mg PR-fampridine twice a day, to test for the responder status. A responder was defined as a 10% improvement at the timed 25-foot walk test (T25fWT) and any improvement in the multiple sclerosis walking scale (MSWS-12) at the end of the 4-week run-in period. Non-responders were subsequently excluded from the study. Responders then underwent a 2-week wash-out period before entering the main phase of the study. Included participants were randomly allocated (1:1 ratio) by a computer software to receive either 6 weeks of PR-fampridine (Fampyra®, Biogen; 10mg b.i.d.) followed by a 2-week wash-out period and a 6-week course of placebo (manufactured to appear identical to Fampyra), or the other way-round. Participants, therapists and assessors were blinded to the condition. Participants were assessed before (w6) and after (w12) the first treatment period and again before (w14) and after the second period (w20). | ||
Evidence for comparator |
This is a blinded placebo controlled cross-over study aiming to assess the effects of IP on patients reported outcomes and gait analysis. | ||

Recruitment
|
|||||||||||
Recruitment details |
Between February 2013 and April 2015, 39 patients from the MS consultation of the neurology department of our institution Cliniques Universitaires Saint Luc were selected for inclusion. After 4 weeks, fifteen patients were considered non-responding and withdrawn from the rest of the study. . Only 24 patients were included and randomized. | ||||||||||
Pre-assignment
|
|||||||||||
Screening details |
Patients with McDonald's criteria were eligible if they were between 18 and 65 years of age, had a subjective complaint of inability to walk, and had an EDSS score of 6 or less. | ||||||||||

End point title |
External work change under treatment [1] | ||||||||
End point description |
The primary endpoint was to indicate a difference in Wext under treatment with PR-fampridine versus placebo. The expected minimal detectable change15 was assumed to be 15% for the primary endpoint.

Notes [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: For each outcome, repeated measures ANCOVAs were applied, with the treatment being the explicative variable and the within-subject differences between baselines (prePR-fampridine and prePlacebo) being the covariate.16Intention-to-treat (ITT) analysis was performed, including all participants assessed at w6. For missing data, the ‘last observation carried forward’ strategy was applied. |

Adverse events information [1]

Timeframe for reporting adverse events |
Adverse events were screened at each visit (screening, start and end of both phases A and B), from first patient inclusion and until the last patient end of study visit.
|
||||||||||
Adverse event reporting additional description |
No adverse event were reported in our population. Patients screened but non included were excluded because they were considered as non responders according to protocol definition.
