Change From Week 12 (Randomization) to Week 24 in DAS28
Periodo de tiempo: Weeks 12 and 24
|
The DAS28 is a combined index for measuring disease activity in rheumatoid arthritis (RA).
The index includes swollen joint counts (SJC) and tender joint counts (TJC), both scored 0-28 (higher scores indicate higher disease activity), as well as acute phase response (APR) determined as erythrocyte sedimentation rate (ESR), and general health (GH), both scored 1-100 (higher scores indicate higher disease activity).
DAS28 was calculated according to the following formula: DAS28 equals (=) [0.56 multiplied by (*) the square root (√) of TJC] plus (+) [0.28 * √ of SJC] + (0.70 * the natural logarithm (ln) ESR in millimeters per hour (mm/h)] + [0.014 * GH in mm visual analogue assessment (VAS)].
A negative change from randomization indicated improvement.

Percentage of Participants With DAS28 Remission at Week 24
Periodo de tiempo: Week 24
|
The DAS28 is a combined index for measuring disease activity in RA.
The index includes SJC and TJC, both scored 0-28 (higher scores indicate higher disease activity, as well as APR determined as ESR, and GH, both scored 1-100 (higher scores indicate higher disease activity).
DAS28 was calculated according to the following formula: DAS28 = 0.56 * √ of TJC + 0.28 * √ of SJC + 0.70 * ln ESR mm/hr + 0.014 * GH in mm VAS.
DAS28 < 2.6 = remission.

Week 24

vPercentage of Participants With Clinical Disease Activity Index (CDAI) Remission at Week 24
Periodo de tiempo: Week 24
|
The CDAI is a combined index for measuring disease activity in RA.
CDAI is the sum of TJC and SJC, both scored 0-28 (higher scores indicate higher disease activity), as well as patient global assessment (PGA) and evaluator global assessment (EGA) of disease activity, both scored 0 to 10 centimeter (cm) as assessed by VAS.
CDAI was calculated according to the following formula: CDAI = SJC + TJC + PGA + EGA.
CDAI < 2.8 = remission.
|
Week 24
|
|
Percentage of Participants With Simplified Disease Activity Index (SDAI) Remission at Week 24
Periodo de tiempo: Week 24
|
The SDAI is a combined index for measuring disease activity in RA.
SDAI is the sum of TJC and SJC, both scored 0-28 (higher scores indicate higher disease activity), PGA and EGA of disease activity, both scored 0 to 10 cm as assessed by VAS, and C-reactive protein level (CRP) in milligrams per deciliter (mg/dL) where normal < 1 mg/dL.
CDAI was calculated according to the following formula: SDAI = TJC + SJC + PGA + EGA + CRP.
SDAI < 3.3 = remission.

Percentage of Participants With Rheumatoid Arthritis Disease Activity Index-5 (RADAI-5) Remission at Week 24
Periodo de tiempo: Week 24
|
The RADAI-5 is a combined index for measuring disease activity in RA.
RADAI-5 is comprised of the following 5 questions: how active was your arthritis the last 6 months?
(0 = completely inactive to 10 = extremely active); how active is your arthritis today with respect to joint tenderness and swelling?
(0 = completely inactive to 10 = extremely active); how severe is your arthritis pain today?
(0 = no pain to 10 = unbearable pain); how would you describe your general health today?
(0 = very good to 10 = very bad); and did you experience joint (hand) stiffness on awakening yesterday morning?
If yes, how long did this stiffness last?
(0 = no stiffness to 10 = stiffness the whole day).
RADAI was calculated according to the following formula: [question (Q) 1 + Q2 + Q3 + Q4 + Q5]/5.
RADAI-5 from 0-1.4 = remission.

Change From Week 12 (Randomization) to Week 24 in Health Assessment Questionnaire - Disability Index (HAQ-DI) Score
Periodo de tiempo: Weeks 12 and 24
|
HAQ-DI scores were obtained by scoring participants' responses to a 20-item questionnaire.
HAQ-DQ evaluated 8 domains of health: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and common daily activities from a range of 0 (without any difficulty) to 3 (unable to do).
The sum of scores was divided by the number of domains for a total score of 0 (best) to 3 (worst).
A negative change from randomization indicated improvement.

|
|
Change From Week 12 (Randomization) to Week 24 in Short Form-36 Health Survey (SF-36) Score
Periodo de tiempo: Weeks 12 and 24
|
SF-36 scores were obtained by scoring participants' responses to a 36-item questionnaire.
SF-36 evaluated 8 aspects of functional health and well being: physical and social functioning, physical and emotional role limitations, bodily pain, general health, vitality, mental health from a range of 1 (better) to 5 (worst).
The score for each section was an average of the individual question scores, which were scaled 0-100 (100=highest level of functioning).
These 8 aspects were summarized as physical and mental component scores.
A negative change from randomization indicated improvement.

Weeks 12 and 24
|
|
Change From Week 12 (Randomization) to Week 24 in Visual Analog Scales (VAS) Scores
Periodo de tiempo: Weeks 12 and 24
|
VAS scores were obtained by scoring participants' disease activity as assessed on a 0-100 millimeter (mm) horizontal visual scale.
The left-hand extreme of the line = 0 mm (no disease activity = symptom-free and no arthritis symptoms), and the right-hand extreme of the line = 100 mm (maximum disease activity).
A negative change from randomization indicated improvement.

Weeks 12 and 24
|
|
Participant Satisfaction With Treatment as Assessed by Treatment Satisfaction Questionnaire for Medication (TSQM) Score
Periodo de tiempo: Week 24
|
TSQM scores were obtained by scoring participants' responses to a 14-item questionnaire.
TSQM evaluated 4 aspects of treatment satisfaction: effectiveness, side effects, convenience, and global satisfaction from a range of 0 to 100 percent (%), with 100% being the best possible result.
