Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Modified Total Sharp Score (mTSS) at Month 6 [ Time Frame: Month 6 ]
    mTSS: sum of erosion and joint space narrowing (JSN) scores for 44 joints (16 per hand and 6 per foot). mTSS scores range from 0 (normal) to 448 (worst possible total score).

  2. Change From Baseline at Month 6 in mTSS [ Time Frame: Month 6 ]
    mTSS: sum of erosion and JSN scores for 44 joints (16 per hand and 6 per foot). mTSS scores range from 0 (normal) to 448 (worst possible total score). An increase in mTSS from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represents improvement.

  3. Percentage of Participants Achieving American College of Rheumatology 70 (ACR70) Response at Month 6 [ Time Frame: Month 6 ]
    ACR70 response: greater than or equal to (≥) 70 percent (%) improvement in tender joints count (TJC) or swollen joints count (SJC) and ≥70% improvement in at least 3 of 5 remaining ACR core measures: 1) physician's global assessment of disease activity, 2) participant's assessment of disease activity, 3) participant's assessment of pain, 4) participant's assessment of functional disability (disability index of the Health Assessment Questionnaire [HAQ]), and 5) C-reactive protein (CRP).

  4. Absolute Blood Pressure (BP) Values (mmHg) [ Time Frame: Baseline and Months 1, 2, 3, 6, 9, 12, 15, 18, and 24 ]
    BP: pressure exerted by the blood upon the walls of the blood vessels and especially arteries, usually measured on the radial artery using a sphygmomanometer. Systolic BP: the highest arterial blood pressure of a cardiac cycle occurring immediately after systole of the left ventricle of the heart. Diastolic BP: the lowest arterial blood pressure of a cardiac cycle occurring during diastole of the heart.

  5. Change From Baseline in BP Values (mmHg) [ Time Frame: Months 1, 2, 3, 6, 9, 12, 15, 18, and 24 ]
    BP: pressure exerted by the blood upon the walls of the blood vessels and especially arteries, usually measured on the radial artery using a sphygmomanometer. Systolic BP: the highest arterial blood pressure of a cardiac cycle occurring immediately after systole of the left ventricle of the heart. Diastolic BP: the lowest arterial blood pressure of a cardiac cycle occurring during diastole of the heart.


Secondary Outcome Measures :
  1. mTSS Score at Baseline, Months 12 and 24 [ Time Frame: Baseline, Months 12 and 24 ]
    mTSS: sum of erosion and JSN scores for 44 joints (16 per hand and 6 per foot). mTSS scores range from 0 (normal) to 448 (worst possible total score).

  2. Change From Baseline in mTSS Score at Months 12 and 24 [ Time Frame: Months 12 and 24 ]
    mTSS: sum of erosion and JSN scores for 44 joints (16 per hand and 6 per foot). mTSS scores range from 0 (normal) to 448 (worst possible total score). An increase in mTSS from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represents improvement.

  3. Percentage of Participants With no Progression in mTSS at Months 6, 12, and 24 [ Time Frame: Months 6, 12, and 24 ]
    mTSS: sum of erosion and JSN scores for 44 joints (16 per hand and 6 per foot). mTSS scores range from 0 (normal) to 448 (worst possible total score). A increase of less than or equal to (≤)0.5 in mTSS is considered to be no progression in the mTSS.

  4. Percentage of Participants With no Worsening in Erosion Score (Increase ≤0.5) at Months 6, 12, and 24 [ Time Frame: Months 6, 12, and 24 ]
    Joint erosion score: erosion severity in 44 joints (16 per hand, 6 per foot). Each joint scored according to surface area involved, from 0 (no erosion) to 5 (extensive bone loss from more than one half of articulating bone). Because each side of foot joint was graded, maximum erosion score for foot joint was 10. Thus, maximum erosion score was 280. An increase of ≤0.5 in Erosion Score is considered to be 'no worsening' in the Erosion Score.

  5. Erosion Scores [ Time Frame: Baseline, Months 6, 12, and 24 ]
    Joint erosion score: erosion severity in 44 joints (16 per hand, 6 per foot). Each joint scored according to surface area involved, from 0 (no erosion) to 5 (extensive bone loss from more than one half of articulating bone). Because each side of foot joint was graded, maximum erosion score for foot joint was 10. Thus, maximum erosion score was 280.

  6. JSN Scores [ Time Frame: Baseline, Months 6, 12, and 24 ]
    JSN score: severity of JSN in 42 joints (15 per hand and 6 per foot), including subluxation, scored from 0 (no/normal JSN) to 4 (complete loss of joint space, bony ankylosis, or luxation). Maximum JSN score was 168.

  7. Change From Baseline in Erosion Scores [ Time Frame: Months 6, 12, and 24 ]
    Joint erosion score: erosion severity in 44 joints (16 per hand, 6 per foot). Each joint scored according to surface area involved, from 0 (no erosion) to 5 (extensive bone loss from more than one half of articulating bone). Because each side of foot joint was graded, maximum erosion score for foot joint was 10. Thus, maximum erosion score was 280. Change = score at observation minus score at Baseline. An increase in score from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represented improvement.

  8. Change From Baseline in JSN Scores [ Time Frame: Months 6, 12, and 24 ]
    JSN score: severity of JSN in 42 joints (15 per hand and 6 per foot), including subluxation, scored from 0 (no/normal JSN) to 4 (complete loss of joint space, bony ankylosis, or luxation). Maximum JSN score was 168. Change = scores at observation minus score at Baseline. An increase in score from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represented improvement.

The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worse score) to 52 (better score). A higher score reflected an improvement in the participant's health status
