What researchers measure

Primary outcomes

  1. Percent of Participants Achieving American College of Rheumatology Criteria 20% Response Rate (ACR20)

    The ACR20/50/70 is a composite measure defined as both improvement of 20%, 50% or 70% in the number of tender and number of swollen joints, and a 20%, 50% or 70% improvement in three of the following five criteria: patient global assessment, physician global assessment, functional ability measure \[most often Health Assessment Questionnaire (HAQ)\], visual analog pain scale, and erythrocyte sedimentation rate or C-reactive protein (CRP).

    Time frame: At 16 weeks

Secondary outcomes

  1. Percent of Participants Achieving Psoriasis Area Severity Index (PASI) 75 Response Rate

    To calculate the PASI score, the psoriasis plaques found on each body region are graded for their combined redness, thickness, and scaliness. The severity of the plaques in each region is graded on a 0 to 4 scale, with 0 meaning no involvement and 4 meaning severe involvement. Next, the amount of surface area on each body region that is covered by the plaques is calculated. The total surface area affected by psoriasis is graded from 0 to 6, with 0 meaning no involvement and 6 meaning greater than 90 percent of the region covered in plaques. These grades are then fed into an equation to determine the patient's PASI score. The PASI score then is used as a clinical assessment of the patient's psoriasis involvement. A person free of psoriasis has a score of 0 and the score could be as high as 72. PASI 75 means that the person's PASI score dropped by 75 percent as a result of the psoriasis treatment.

    Time frame: Week 16 and Week 24

  2. Percent of Participants Achieving ACR50 and ACR70 Response Rate

    The ACR20/50/70 is a composite measure defined as both improvement of 20%, 50% or 70% in the number of tender and number of swollen joints, and a 20%, 50% or 70% improvement in three of the following five criteria: patient global assessment, physician global assessment, functional ability measure \[most often Health Assessment Questionnaire (HAQ)\], visual analog pain scale, and erythrocyte sedimentation rate or C-reactive protein (CRP).

    Time frame: Week 16 and Week 24

  3. Percent of Participants Achieving ACR20 Response Rate at Week 24

    The ACR20/50/70 is a composite measure defined as both improvement of 20%, 50% or 70% in the number of tender and number of swollen joints, and a 20%, 50% or 70% improvement in three of the following five criteria: patient global assessment, physician global assessment, functional ability measure \[most often Health Assessment Questionnaire (HAQ)\], visual analog pain scale, and erythrocyte sedimentation rate or C-reactive protein (CRP).

    Time frame: Week 24

  4. Percent of Participants Achieving a Health Assessment Questionnaire (HAQ) Response

    For each item, there is a four-level difficulty scale that is scored from 0 to 3, representing normal (no difficulty) (0), some difficulty (1), much difficulty (2), and unable to do (3). There are 20 questions in eight categories of functioning - dressing, rising, eating, walking, hygiene, reach, grip, and usual activities. The highest component score in each category determines the score for the category, unless aids or devices are required. Dependence on equipment or physical assistance increases a lower score to the level of 2 to more accurately represent underlying disability. The eight category scores are averaged into an overall HAQ score on a scale from zero (no disability) to three (completely disabled). The scale is not truly continuous but has 25 possible values (i.e., 0, 0.125, 0.250, 0.375 ... 3). Response is measured by a reduction of at least 0.3 unit from baseline in HAQ index.

    Time frame: Weeks 16 and Week 24

  5. Mean Change From Baseline at Week 16 in Short Form (36) [SF-36] Scores

    The SF-36 questionnaire consists of eight scales yielding two summary measures: physical and mental health. The physical health measure includes four scales of physical functioning (10 items), role-physical (4 items), bodily pain (2 items), and general health (5 items). The mental health measure is composed of vitality (4 items), social functioning (2 items), role-emotional (3 items), and mental health (5 items). To score the SF-36, scales are standardized with a scoring algorithm to obtain a score ranging from 0 to 100. Higher scores indicate better health status.

    Time frame: Baseline and Week 16

  6. Mean Change From Baseline at Week 24 in SF-36 Scores

    The SF-36 questionnaire consists of eight scales yielding two summary measures: physical and mental health. The physical health measure includes four scales of physical functioning (10 items), role-physical (4 items), bodily pain (2 items), and general health (5 items). The mental health measure is composed of vitality (4 items), social functioning (2 items), role-emotional (3 items), and mental health (5 items). To score the SF-36, scales are standardized with a scoring algorithm to obtain a score ranging from 0 to 100. Higher scores indicate better health status.
