Percentage of Participants Achieving Disease Activity Score 28 (DAS28) Remission (DAS28 < 2.6) at Weeks 24 and 48 |
The Disease Activity Score (DAS28) score is a measure of the subject's disease activity. It is based on the tender joint count (28 joints), swollen joint count (28 joints), patient's global assessment of disease activity and Erythrocyte Sedimentation Rate (ESR). DAS28 total scores range from 0 to approximately 10. Scores below 2.6 indicate best disease control and scores above 5.1 indicate worse disease control. A negative change from Baseline indicated improvement. |

Change From Baseline in the Health Assessment Questionnaire Disability Index (HAQ-DI) at Weeks 24 and 48 |
HAQ-DI is a self-completed patient questionnaire specific for Rheumatoid Arthritis. It consists of 20 questions referring to 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip; common daily activities. Each domain has at least 2 component questions. There are 4 possible responses for each component 0=without any difficulty 1=with some difficulty 2=with much difficulty 3=unable to do. Calculate HAQ-DI the patient must have a domain score for at least 6 of 8 domains. The HAQ-DI is the sum of the scores, divided by the number of domains that have a score (in range 6-8) for a total possible score minimum/maximum 0 (best) to 3 (worst).

Change From Baseline in the Modified Total Sharp Score (mTSS) at Weeks 24 and 48 |
mTSS: measure of joint damage that combines scores for bone erosion and joint space narrowing (JNS). Erosion score: total of 14 locations in each hand and wrist and 6 joints in the foot were evaluated for erosion using an 8-point scale where 0=normal to 3.5=very severe erosion. JNS score: total of 13 locations in each hand and wrist and 6 joints in the foot were evaluated for joint narrowing score using a 9-point scale where 0=normal to 4.0=definite ankylosis (stiffness or fixation of a joint). mTSS scores ranged from 0 (normal) to 292 (worst possible total score). Change= mTSS score at Week 24 minus score at baseline. An increase in mTSS from baseline represents disease progression and/or joint worsening, no change represents halting of disease progression, and a decrease represents improvement. |

Change From Baseline in Modified Erosion Score at Weeks 24 and 48 |
The erosion score is a summary of erosion severity in 32 joints of the hands (16 joints per hand) and 12 joints in the feet (6 joints per foot). Each joint is scored, according to the surface area involved, from 0 to 5, with 5 indicating extensive loss of bone from more than one-half of the articulating bone (0 indicates no erosion). Because each side of a foot joint is graded separately on this scale, the maximum erosion score for a foot joint is 10. The maximal erosion score is 280. |

The joint space narrowing score summarizes the severity of joint space narrowing in 30 joints of the hands and 12 joints of the feet. Assessment of joint space narrowing for each hand (15 joints per hand) and foot (6 joints per foot), including subluxation, is scored from 0 to 4, with 0 indicating no/normal joint space narrowing and 4 indicating complete loss of joint space, bony ankylosis, or luxation. The maximum joint space narrowing score is 168. |

Percentage of Participants Without Radiographic Progression Defined as Change in mTSS = 0 at Weeks 24 and 48 |
Radiographic progression was defined as a change of = 0 in the total Genant-modified Sharp score. The Genant-modified Sharp scoring system assesses structural damage due to rheumatoid arthritis in radiographs. A score for erosions of 0-3.5 (8 gradations) is assigned for 14 joints in each hand and wrist, and 6 joints in each foot. Joint space narrowing scores of 0-4 (9 gradations) are assigned to 13 joints in each hand and 6 joints in each foot. The maximum erosion score is 40 x 3.5 = 140. The maximum joint space narrowing score is 38 x 4.0 = 152. Both the erosion and joint space narrowing scores are normalized to 145 and are added together for a maximum total Genant-modified Sharp score of 290; the minimum score is 0. A higher score indicates more damage. |

The SF-36 is a questionnaire used to assess physical functioning and is made up of eight domains: Physical Functioning, Role Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional and Mental Health. Transforming and standardizing these domains leads to the calculation of the Physical and Mental Component Summary measures. Scores ranging from 0 to 100, with 0=worst score (or quality of life) and 100=best score. A positive change from baseline indicates improvement. |

Change From Baseline in Functional Assessment of Chronic Illness Therapy-Fatigue Scale (FACIT-F) Fatigue Assessment at Weeks 24 and 48 |
The FACIT-Fatigue score was calculated according to a 13-item questionnaire that assesses self-reported fatigue and its impact upon daily activities and function. FACIT-F is a 13-item questionnaire. Participants scored each item on a 5-point scale: 0 (Not at all) to 4 (Very much). The larger the participant's response to the questions (with the exception of 2 negatively stated), the greater the participants 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). Clinically relevant improvement is defined as a greater than or equal to (=)5-point change from Baseline. |

Change From Baseline in Pain Quality and Impact of Pain on Daily Function Measured by the Brief Pain Inventory (BPI) Short Form at Weeks 24 and 48 |
The modified BPI (short-form) is a short questionnaire to assess the severity of pain and the impact of pain on daily functions. The first two questions relate to average and current pain respectively and are assessed on a scale from 0 to 10, where 0 represents no pain, and 10 represents pain as bad as one can imagine. The degree to which pain has interfered with 7 different aspects is also rated on a scale from 0 to 10, where 0 represents that pain does not interfere and 10 that pain completely interferes. |
