Efficacy and Safety of FTY720 in Patients With Relapsing Multiple Sclerosis

Total number of post-baseline Gd-enhanced lesions is calculated as a sum of all Gd-enhanced lesions seen on post-baseline scans per visit. Real (not per slice) lesions are counted in this analysis.

Total number of post-baseline Gd-enhanced lesions is calculated as a sum of all Gd-enhanced lesions seen on post-baseline scans per visit. Real (not per slice) lesions are counted in this analysis. The last observation was the last observation available for each patient which ranged from 1 to 2801 days

A patient was defined as free of lesions if s/he had zero lesions. The last observation was the last observation available for each patient which ranged from 1 to 2801 days

A patient was defined as free of lesions if s/he had zero lesions. The sum of all new T2-weighted lesions at Month 1 to last observation was zero (the sum is missing if one of the assessments was missing). New T2 lesions at a specific visit were assessed relative to the previous visit scan. Exception: new T2 lesions at Month 24 were assessed relative to Month 12. The last observation was the last observation available for each patient which ranged from 1 to 2801 days

New T2 lesions at a specific visit were assessed relative to the previous visit scan. The total number of lesions (Month 1 to end of study) is calculated as the sum of the number of lesions at Months 1 to 6, Month 12, Month 60 and last observation. The last observation was the last observation available for each patient which ranged from 1 to 2801 days

Volume of total T2-weighted lesions by visit were summarized. The last observation was the last observation available for each patient which ranged from 1 to 2801 days

Change in volume of total T2-weighted lesions by visit were summarized. Negative values indicate improvement (reduction in lesion volume) and positive values worsening (increase in lesion volume). The last observation was the last observation available for each patient which ranged from 1 to 2801 days.

The Expanded Disability Status Scale (EDSS) is a scale for assessing disability in 8 functional systems (visual, brain stem, pyramidal, cerebellar, sensory, bowel & bladder, cerebral, other functions). An overall score ranging from 0 (normal) to 10 (death due to MS) is calculated. Disability progression was determined by the EDSS score based on the following criteria: One point increase from baseline in patients with baseline EDSS score from 0 to 5.0; or half a point increase in patients with baseline EDSS score of 5.5 or above. Percent of patients free of disability progression was calculated using the Kaplan-Meier method. The last observation was the last observation available for each patient which ranged from 1 to 2801 days

For each patient, the arithmetic mean of the two FTY720 trough blood levels from month 3 and 6 was calculated. This was taken as the patient's steady-state trough levels. Venous blood samples (3 mL) were collected before the dose in ethylenediaminetetraacetic acid (EDTA)-containing tubes at protocol-scheduled visits at months 3 and 6 in all patients.
