Thirty Six-Item Short-Form Health Survey (SF-36) Physical Component Score (PCS) and Mental Component Score (MCS) at Baseline	Baseline	SF-36 is a standardized survey evaluating 8 aspects of functional health and well-being: physical and social functioning, physical and emotional role limitations, bodily pain, general health, vitality, mental health. These 8 aspects can also be summarized as PCS and mental component score MCS. The score for each aspect and PCS/MCS is an average of the individual question scores, which are scaled 0-100 (100=highest level of functioning). LOCF method was used to impute missing values.
Change From Baseline in 36-Item Short-Form Health Survey (SF-36) PCS and MCS at Week 4, 8, 12, 16, 20 and 24	Baseline, Week 4, 8, 12, 16, 20, 24	SF-36 is a standardized survey evaluating 8 aspects of functional health and well-being: physical and social functioning, physical and emotional role limitations, bodily pain, general health, vitality, mental health. These 8 aspects can also be summarized as physical component score (PCS) and mental component score (MCS). The score for each aspect and PCS/MCS is an average of the individual question scores, which are scaled 0-100 (100=highest level of functioning). LOCF method was used to impute missing values.
Change From Baseline in Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) Score at Week 4, 8, 12, 16, 20 and 24	Baseline, Week 4, 8, 12, 16, 20, 24	FACIT-F is a 13-item questionnaire. Participants scored each item on a 5-point scale: 0 (not at all) to 4 (very much). Larger the participant's response to the questions (with the exception of 2 negatively stated), greater was the participant's fatigue. For all questions, except for the 2 negatively stated ones, the code was reversed and a new score was calculated as (4 minus the participant's response). The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worse score) to 52 (better score). LOCF method was used to impute missing values.
Patient Global Visual Analog Scale (VAS) Scores at Baseline	Baseline	Participants assessed their disease activity using a 100 millimeter (mm) VAS. Participants answered the following question "Considering all the ways your disease affects you, how are you feeling today?" Response was recorded by placing a mark on the scale between 0 (very well) and 100 (extremely bad).
Change From Baseline in Vitality Scores at Week 4, 8, 12, 16, 20 and 24	Baseline, Week 4, 8, 12, 16, 20, 24	SF-36 is a standardized survey evaluating 8 aspects of functional health and well being: physical and social functioning, physical and emotional role limitations, bodily pain, general health, vitality, mental health. Vitality sub-score is a component of SF-36 Health Survey Questionnaire and assesses energy and fatigue. The vitality score ranged from 0-100 (100=highest level of functioning). LOCF method was used to impute missing values.
Change From Baseline in Short Form-6 Dimension (SF-6D) at Week 4, 8, 12, 16, 20 and 24	Baseline, Week 4, 8, 12, 16, 20, 24	The SF-6D focuses on seven of the eight health domains covered by the SF-36 Health Survey: physical functioning, role participation (combined role-physical and role-emotional), social functioning, bodily pain, mental health, and vitality. The SF-6D is an attempt to derive a single index from the SF-36 Health Survey for use in economic evaluation studies. As such, it represents a summary score based on a subset of the SF-36 data. Consequently, in lieu of the SF-6D, PCS and MCS SF-36 results are being provided. The score for each aspect and PCS/MCS is an average of the individual question scores, which are scaled 0-100 (100=highest level of functioning). LOCF method was used to impute missing values.
Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) Score at Baseline	Baseline	FACIT-F is a 13-item questionnaire. Participants scored each item on a 5-point scale: 0 (not at all) to 4 (very much). Larger the participant's response to the questions (with the exception of 2 negatively stated), greater was the participant's fatigue. For all questions, except for the 2 negatively stated ones, the code was reversed and a new score was calculated as (4 minus the participant's response). The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worse score) to 52 (better score).
