Design outcomes

Primary

MeasureTime frameDescription
Change from Baseline in EuroQol 5D (EQ-5D) Visual Analog Scale (VAS) at 12 monthsBaseline and Month 12Quality of life will be assessed on a visual analog scale from 0 = worst imaginable health status to 100 = best imaginable health status.

Secondary

MeasureTime frameDescription
Change from Baseline in the Multiple Sclerosis Impact Scale-29 (MSIS-29) scoreBaseline and Months 6, 12, 18 and 24The 29-item Multiple Sclerosis Impact Scale (MSIS-29) is a patient-reported outcome measure to assess the impact of MS on day-to-day life during the past 2 weeks from a patient's perspective; it measures 20 physical items and 9 psychological items. The scores are generated by summing individual items and then transforming to a scale with a range of 0 to 100, where high scores indicate worse health.
Change from Baseline in EQ-5D Summary ScoreBaseline and Months 6, 12, 18 and 24The EQ-5D is a self-administered questionnaire consisting of 5 questions pertaining to specific health states (i.e., mobility, self-care, pain/discomfort, usual activities and anxiety/depression), with three possible answers for each item (1=no problem, 2=moderate problem, 3=severe problem). A summary index with a maximum score of 1 is derived from these five dimensions where a score of 1 indicates the best health state.
Change from Baseline in EQ-5D VAS at 6, 18 and 24 monthsBaseline and Months 6, 18 and 24Quality of life will be assessed on a visual analog scale from 0 = worst imaginable health status to 100 = best imaginable health status.
Correlation between VAS and MSIS29Baseline and Months 6, 12, 18 and 24The correlation between the EQ-5D visual analog scale and Multiple Sclerosis Impact Scale 29 scores will be assessed using the Spearman correlation coefficient.
Correlation between VAS and Convenience questionnaireBaseline and Months 6, 12, 18 and 24The correlation between the EQ-5D visual analog scale and convenience questionnaire results will be assessed using the Spearman correlation coefficient.
ConvenienceBaseline and Months 6, 12, 18 and 24Convenience will be assessed by a self-administered convenience questionnaire that asks participants about their treatment satisfaction over the past 2 weeks.
