Study Comparing Etanercept With Usual DMARD Therapy in Subjects With Rheumatoid Arthritis in the Asia Pacific Region

ACR-N = the lowest of 3 values (percent change in the number of swollen joints, percent change in the number of tender joints, and median of the other 5 measures in the ACR core data set). Negative numbers indicate worsening. The ACR-N AUC was calculated using the trapezoidal rule as the ACR-N multiplied by the duration of the assessment period (in weeks) and was presented as %-weeks.

Time frame: 16 weeks

Population: The mITT population, defined as all randomly assigned subjects who received at least 1 dose of ETN or MTX in the ETN group or 1 dose of usual DMARD therapy medication or MTX in the usual DMARD therapy group and had at least 1 postbaseline assessment.

Response includes improvement in tender or swollen joints as well as 20 percent improvement in three of the other five criteria. Required: ≥ 20%, 50% or 70% improvement in tender joint count ≥ 20% , 50% or 70% improvement in swollen joint count and at least 20%, 50%, 70% improvement in 3 of the following 5:Patient pain assessment , Patient global assessment ,Physician global assessment, Patient self-assessed disability.

Time frame: Week 16

Population: The mITT population, defined as all randomly assigned subjects who received at least 1 dose of ETN or MTX in the ETN group or 1 dose of usual DMARD therapy medication or MTX in the usual DMARD therapy group and had at least 1 postbaseline assessment.

Disease Activity Score 28 based on 28 Joints (DAS28) is the calculation of DAS28: DAS28 = 0.56 sqrt (28 painful joint count) + 0.28 sqrt (28 swollen joint count) + 0.70 (ln erythrocyte sedimentation rate (ESR)) + 0.014 (General Health) (GH). GH = Subject general health visual analog scale (0-10 mm).

Population: The mITT population, defined as all randomly assigned subjects who received at least 1 dose of ETN or MTX in the ETN group or 1 dose of usual DMARD therapy medication or MTX in the usual DMARD therapy group and had at least 1 postbaseline assessment.

EULAR Response Criteria DAS28) improvement at week 16. Good response was defined as \>1.2 improvement in DAS from Baseline and DAS attained during follow-up of ≤2.4. Non-responders were participants with improvement of ≤0.6 or participants with improvement of \>0.6 but ≤1.2 and DAS attained during follow-up of \>3.7. Remaining participants were classified as moderate. Scores of good and moderate were considered to have therapeutic response.

Disease Activity Score 28 based on 28 Joints (DAS28) is the calculation of DAS28: DAS28 = 0.56 sqrt (28 painful joint count) + 0.28 sqrt (28 swollen joint count) + 0.70 (ln erythrocyte sedimentation rate (ESR) + 0.014 (General Health) (GH). GH = Subject general health visual analog scale (0-10 mm).

The duration of morning stiffness on the day of examination should be determined by asking the following two questions: When did you awaken this morning? When were you able to resume your normal activities without stiffness? Duration of morning stiffness is equal to the time elapsed between the above two times in minutes; If none is present enter 0, If morning stiffness is still continuing, please indicate average of duration of stiffness over the past 3 days. If stiffness persists the entire day 1440 minutes (24h x 60 minutes) should be recorded.

Time frame: Week 2, 4, 8, 12, 16

Population: The mITT population, defined as all randomly assigned subjects who received at least 1 dose of ETN or MTX in the ETN group or 1 dose of usual DMARD therapy medication or MTX in the usual DMARD therapy group and had at least 1 postbaseline assessment.

VAS, participant indicates by marking a vertical line at an appropriate position through a horizontal line. The length of the line measures from left (in mm) and the value (in mm) is recorded. General Health VAS, in general how would you rate your heath over the last 2-3 weeks, 0mm equals very well and 100mm equals extremely bad. Pain VAS: indicate the amount of pain experienced during the last 2-3 days, 0 mm equals no pain and 100 mm equals pain as bad as it can be. Fatigue VAS: how fatigued or tired have you been over the last week, range =No Fatigue - Extremely Fatigued.

Time frame: Week 2, 4, 8, 12, 16

Population: The mITT population, defined as all randomly assigned subjects who received at least 1 dose of ETN or MTX in the ETN group or 1 dose of usual DMARD therapy medication or MTX in the usual DMARD therapy group and had at least 1 postbaseline assessment.

Participant's assessment of pain - A horizontal pain visual analog scale (VAS) (0-100 mm) is used to assess the participants current level of pain; 0 = no pain and 100 = worst pain. Swollen joint count - ACR swollen joint count, an assessment of 28 joints. Joints are classified as either swollen or not swollen.

Time frame: Week 2, 4, 8, 12, 16

Population: The mITT population, defined as all randomly assigned subjects who received at least 1 dose of ETN or MTX in the ETN group or 1 dose of usual DMARD therapy medication or MTX in the usual DMARD therapy group and had at least 1 postbaseline assessment.

The Physician Global Assessment of Disease Activity: The participant's disease activity is estimated over the last two - three days by the physician; A zero (0) means no disease activity and a ten (10) means extreme disease activity. The Subject Global Assessment of Disease Activity: The participant assesses overall arthritis activity. A zero (0) means no disease activity and a ten (10) means extreme disease activity.
