Design outcomes

Primary

MeasureTime frame
Secondary Objective: To obtain clinical experience with the transition to RNF in order to provide physicians with recommendations how to best manage this transition through the use of concomitant ibuprofen.;Primary end point(s): The primary endpoint is the FLS score from the MSTCQ at week 4. This is defined as the sum of the scores for “side effects” section questions 1-4, corresponding to a maximum total score of 20.;Main Objective: To assess subject satisfaction by the MS Treatment Concern Questionnaire (MSTCQ) specifically measuring Flu Like Symptoms (FLS) during the first 4 weeks after subjects transitioned to RNF in 2 treatment groups: one treatment group receives ibuprofen prophylactically and the other ibuprofen PRN.
