- Change From Baseline in the Medication Satisfaction Questionnaire (MSQ) to Month 6 Using a Repeated Measures ANCOVA [ Time Frame: Baseline (Month 0), Months 1, 3 and 6 ]Patient satisfaction with the study medication was assessed using the MSQ a 1-item global patient-rated scale. Patients were asked to respond on a 7-point scale, ranging from extremely dissatisfied (1) to extremely satisfied (7), to the following: "Overall, how satisfied are you with your current medication?". Positive change from baseline score indicates greater satisfaction with the medication. Estimates and p-value are obtained from baseline-adjusted repeated measures ANCOVA model with visit as a repeated effect: MSQ=baseline MSQ score+treatment+visit+treatment by visit interaction.
- Change From Baseline in the Treatment Satisfaction Questionnaire for Medication 9-item Version (TSQM-9) Convenience Score to Month 6 Using a Repeated Measures ANCOVA [ Time Frame: Baseline (Month 0), Months 1, 3 and 6 ]Convenience perception was measured by the 3 convenience items (items 4 to 6) within the validated TSQM-9. The responses to each of the 3 convenience items are reported on a 1-to-7 scale. The TSQM-9 convenience scale is computed, for each subject, by adding the 3 items loading on each response with the lowest possible total score (1*3 on the 3 items) subtracted from this composite score, and divided by the greatest possible score (3*7) minus the lowest possible score (3), i.e., 21-3=18. This provides a transformed score between 0 and 1 that was multiplied by 100. The final scale is 0 (Extremely Difficult/Inconvenient) to 100 (Extremely Easy/Convenient). If more than one item is missing, then the convenience scale was considered invalid for that patient. Estimates and p-value are obtained from baseline-adjusted repeated measures ANCOVA with treatment, visit, and Country/Geographical Region as main factors, visit by treatment as the interaction term, and baseline score as the covariate.
- Change From Baseline in the Modified Fatigue Impact Scale (MFIS) Total Score and Subscales to Month 6 Using a Repeated Measures ANCOVA [ Time Frame: Baseline (Month 0), Months 1, 3 and 6 ]MFIS is a modified form of the Fatigue Impact Scale based on items derived from interviews with MS patients concerning how fatigue impacts their lives. It is a structured, self-report questionnaire consisting of 21 items assessing the effects of fatigue. All 21 items are scaled 0 to 4, with higher scores indicating a greater impact of fatigue on patient's activities. The Total MFIS score ranges from 0 to 84, the Physical Subscale from 0 to 36, the Cognitive Subscale from 0 to 40, and the Psychosocial Subscale from 0 to 8. A score of 0 indicates fatigue has no impact on activities and the high-end score indicates fatigue has extreme impact on activities. Negative change from baseline values indicate improvement in the effects of fatigue. Estimates and p-values are obtained from baseline-adjusted repeated measures ANCOVA model with visit as a repeated effect: change from
- Change From Baseline in the Mental Health Index (MHI) Total Score and Subscales to Month 6 Using a Repeated Measures ANCOVA [ Time Frame: Baseline (Month 0), Months 1, 3 and 6 ]The MHI consists of 18 items and provides an assessment of 4 subscales of mental health, including Anxiety (5 items), Depression (4 items), Behavioral control (4 items), and Positive Affect (4 items), and 1 Total Score. The subscales and Total Score for analyses range from 0 to 100, with 0 indicating not mentally healthy and 100 indicating superior mental health. Positive change from baseline scores indicate improved mental health. Estimates and p-values are obtained from baseline-adjusted repeated measures ANCOVA model with visit as a repeated effect: change from baseline MHI score=baseline MHI Total Score +treatment +visit +country/geographic region +treatment by visit interaction. If a participant skipped x items of y items, the scale was not computed: - MHI Total Score - 9 of 19 - Anxiety subscale - 2 of 5 - Depression subscale - 2 of 4 - Behavioral Control subscale - 2 of 4 - MHI Positive Affect subscale - 2 of 4
- Change From Baseline in the Beck Depression Inventory II (BDI-II) Total Score to Month 6 Using a Repeated Measures ANCOVA [ Time Frame: Baseline (Month 0), Months 1, 3 and 6 ]Depressive symptoms were measured by the BDI-II, a 21-item, self-reported rating inventory that measures characteristic attitudes and symptoms of depression. The BDI-II assesses mood, pessimism, sense of failure, self-dissatisfaction, guilt, punishment, self-dislike, self-accusation, suicidal ideas, sadness, crying, irritability, social withdrawal, body image, work difficulties, insomnia, fatigue, appetite, weight loss, bodily preoccupation, and loss of libido. Each of the 21 items is rated on a 4-point scale ranging from 0 to 3. BDI-II Total Score indicates the severity of depression and has a total range of 0 to 63. For those clinically diagnosed, scores from 0-13 represent minimal depressive symptoms, scores of 14-19 indicate mild depression, scores of 20-28 indicate moderate depression, and scores of 30-63 indicate severe depression. Negative change from baseline scores indicate improvement.
- Participants With Treatment-Emergent Adverse Events (TEAEs) During Both the Core Period and Extension Periods [ Time Frame: Core: Day 1 to Month 6 Extension: Month 7 to Month 12 ]An adverse event (AE) is defined as any study-related event that represents a change (positive or negative) in frequency or severity from a baseline (prestudy) event (if any), regardless of the presence of causal relationship or medical significance. Treatment-emergent adverse events are defined as any adverse event with a start date on or after the first study dose date. The investigator determined relation to study drug. A severe AE is defined as an inability to carry out usual activities. A serious AE (SAE) is defined by federal regulation as any AE occurring at any dose that results in any of the following outcomes: death, life-threatening AE, hospitalization or prolongation of existing hospitalization, a persistent or significant disability/incapacity, or a congenital anomaly/birth defect. Although a subject may have had 2 or more adverse experiences the subject is counted only once in a category. The same subject may appear in different categories.
