Part 1: Change From Baseline in the Expanded Disability Status Scale (EDSS) Score
Tidsramme: Baseline, Week 96

The EDSS measures the disability status of participants with multiple sclerosis on a scale that ranges from 0 to 10.
The first levels 1.0 to 4.5 refer to people with a high degree of ambulatory ability and the subsequent levels 5.0 to 9.5 refer to the loss of ambulatory ability.
The range of main categories include (0) = normal neurologic exam; to (5) = ambulatory without aid or rest for 200 meters; disability severe enough to impair full daily activities; to (10) = death due to MS with higher scores indicating more disability.
A negative change from baseline indicated an improvement in the disability.
|
Baseline, Week 96
|
|
Part 2: Annualized Relapse Rate (ARR)
Tidsramme: From Baseline (Week 96) up to Week 336

The first levels 1.0 to 4.5 refer to people with a high degree of ambulatory ability and the subsequent levels 5.0 to 9.5 refer to the loss of ambulatory ability.
The range of main categories include (0) = normal neurologic exam; to (5) = ambulatory without aid or rest for 200 meters; disability severe enough to impair full daily activities; to (10) = death due to MS.
A negative change from baseline indicated an improvement in the disability.

Part 2: Change From Baseline in Brief Visuospatial Memory Test - Revised (BVMT-R) Score
Tidsramme: Baseline (Week 96), Weeks 144,192, 240, 288 and 336
|
BVMT-R is used to assess learning/memory.
In this test, six abstract designs are presented for 10 sec.
The display is removed from view, and participants render the stimuli via pencil on paper, manual responses.
Each design receives from 0 to 2 points, representing accuracy and location.
There are three Learning Trials, and the score is reported as the total number of points earned over the trials.
Thus, scores range from 0 to 12 per trial; total score range is 0 to 36 for all three trials.
Scores were converted to standardized scores using normative data, ranging from 2-86.
The lower the score, the more severe the cognitive impairment while higher scores reflect better visuospatial memory.

Part 2: Change From Baseline in Symbol Digit Modalities Test (SDMT) Score
Tidsramme: Baseline (Week 96), Weeks 144,192, 240, 288 and 336

SDMT is used to assess processing speed.
It consists of 9 abstract symbols.
Each symbol is paired with a single digit.
The participant is provided with a key, showing each symbol digit pair.
In addition, the participants are shown several rows of the 9 symbols, which are arranged pseudo-randomly, without the digit.
Participants are asked to voice the digit associated with each symbol as rapidly as possible for 90 seconds.
The SDMT score ranges from 0 to 110, where higher scores indicate improvement in cognitive functioning and lower scores indicate worsening.

Part 2: Number of Participants With Shifts From Baseline in Clinical Laboratory Parameters (Hematology Parameters)
Tidsramme: Baseline (Week 96) up to Week 340
|
Hematology parameters included leukocytes, erythrocytes, hemoglobin, hematocrit, platelets, eosinophils, lymphocytes, monocytes and neutrophils.
These parameters were flagged as low, normal, or high relative to parameter's normal range or as unknown if no result was available.
Here, shift to low indicated values that were normal, high or unknown at baseline and shifted to low values postbaseline.
Shift to high indicated values that were normal, low or unknown at baseline and shifted to high postbaseline values.
The categories with at least one participant with shift from baseline in these parameters are reported.

Part 2: Number of Participants With Shifts From Baseline in Clinical Laboratory Parameters (Blood Chemistry Parameters)
Tidsramme: Baseline (Week 96) up to Week 340
|
Parameters included potassium, bilirubin, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, urea nitrogen, creatinine, bicarbonate, calcium, magnesium, phosphate, urate and glucose.
These parameters were flagged as low, normal or high relative to parameter's normal range or as unknown if no result was available, by Investigator.
Here, shift to low indicated values that were normal, high or unknown at baseline and shifted to low values postbaseline.
Shift to high indicated values that were normal, low or unknown at baseline and shifted to high values postbaseline.
Categories with at least one participant with shift from baseline in these parameters are reported.

Urinalysis included assessments of erythrocytes, leukocytes and specific gravity.
These parameters were flagged as low, normal, or high relative to parameter's normal range or as unknown if no result was available, by the Investigator.
Here, shift to low indicated values that were normal, high or unknown at baseline and shifted to low values postbaseline.
Shift to high indicated values that were normal, low or unknown at baseline and shifted to high postbaseline.

Part 2: Number of Male Participants by Tanner Stage Assessment
Tidsramme: At Weeks 96, 144, 192, 240, 288 and 336
|
Tanner pubertal staging in males was assessed for testes and scrotum development and pubic hair growth, progressing from stage 1 (prepubertal) to stage 5 (adult).
Assessments ended when bone age reached ≥16 years.
Testes and scrotum stages were: 1-prepubertal; 2-enlargement of testes, scrotum reddens, texture change; 3-Enlargement of penis, further growth of testes; 4-Increased size of penis with growth in breadth and development of glans; testes and scrotum larger, scrotum skin darker; 5-adult genitalia.
Pubic hair stages were: 1-prepubertal; 2-Sparse growth of long, slightly pigmented hair, straight or curled; 3-Darker, coarser and more curled hair, spreading sparsely over junction of pubes; 4-Hair adult in type, but covering smaller area than in adult; no spread to medial surface of thighs; 5-Adult in type and quantity, with horizontal distribution.

Part 2: Number of Female Participants by Tanner Stage Assessment
Tidsramme: At Weeks 96, 144, 192, 240, 288 and 336
|
Tanner pubertal staging in females was assessed for breast development and pubic hair growth, progressing from stage 1 (prepubertal) to stage 5 (adult).
Assessments ended when bone age reached ≥16 years or the participant was post-menarche.
Breast development stages: 1-prepubertal; 2-breast bud stage with elevation of breast and papilla; enlargement of areola, 3-further enlargement of breast and areola; no separation of their contour; 4-areola and papilla form secondary mound above level of breast; 5-mature stage: projection of papilla only, related to recession of areola.
Pubic hair stages: 1-prepubertal (can see velus hair similar to abdominal wall); 2-sparse growth of long, slightly pigmented hair, straight or curled, mainly on labia; 3-Darker, coarser and more curled hair, spreading sparsely over junction of pubes; 4-hair adult in type, but covering smaller area than in adult; no spread to medial surface of thighs; 5-adult in type and quantity, with horizontal distribution.
