Primary outcomes

  1. Improvement in Quality of Life Measured by Change From Baseline in Psychological General Well-Being Scale

    Time frame: baseline, week 28 and week 52

    The Psychological General Well-Being scale is a self-administered validated psychometric instrument that measures a person's emotional well-being. It is specifically designed to be suitable for assessing psychological well being in the general medical population as opposed to a psychiatric population. The 22 questions of the PGWB can be further divided into 6 domains: anxiety, depressed mood, positive well being, self-control, general health, and vitality. The PGWB is graded on a Likert scale, which is commonly used in psychometric questionnaires where the answers range from strongly agree to strongly disagree with gradations in between. Total scores range from 0 to 110, with higher scores indicating better psychological well being. This instrument has been validated and used in many countries on large samples of the general population and on various subsets of medical patients.

    The values reported are change in score from baseline.

Secondary outcomes

  1. Improvement in Quality of Life Measured by Change From Baseline in Psychological General Well-Being Scale Over Time

    Time frame: week 64

    The DLQI is a self-administered and user-friendly validated questionnaire used to measure the health-related quality of life of adult patients suffering from a skin disease. The items of the DLQI encompass aspects such as symptoms and feelings, daily activities, leisure, work or school, personal relationships and the side effects of treatment.

    Higher scores mean greater impairment of patient's QoL. The DLQI or Dermatology Life Quality Index measures patient's quality of life. The score ranges from 0 to 30. Lower scores indicate less impairment in quality of life

  3. Proportion of Subjects With Dermatology Life Quality Index Score of 0 or 1

    For 'Units of Measure'- Data entered is percentage of participants, which is calculated by multiplying the value obtained (Proportion in this case) by 100

  6. Changes From Baseline in Percent Affected Body Surface Area

    Time frame: Weeks 4, 8, 12, 16, 28, 40, 52, and 64

    The percent BSA affected with psoriasis will be estimated at each study visit. The investigator may use the estimate that 1% BSA is equivalent to the area of the subject's closed hand (palm with fingers held together).

  7. Change From Baseline in Static Physician's Global Assessment

    Time frame: Weeks 4, 8, 12, 16, 28, 40, 52, and 64

    The sPGA is used to determine the overall severity of psoriasis lesions at a given time point. Its score ranges from 0 to 5 with higher scores indicating greater severity.

  8. Changes From Baseline Body Surface Area x Physician's Global Assessment Over Time

    Time frame: weeks 4, 8, 12, 16, 28, 40, 52, 64

    The metric of BSA x sPGA is a multiplication of the percentage BSA covered and the sPGA score.

    The scale range for the sPGA is 0 to 5. The scale range for BSA in this study was >=3% (inclusion criterion), which means that it has to be at least 3%, and it can be as high as 100% hypothetically. So the minimum score for sPGA x BSA = 0, and the maximum score is 5 x 100 = 500. So the range for sPGA x BSA in this study was 0 to 500.

    The BSA has a range of 0% to 100% where higher percentages indicate a worse outcome or worse disease

    The sPGA has a range of 0 (clear) to 5 (severe) where higher values indicate a worse outcome or worse disease.

    sPGA is used to determine the overall severity of psoriasis lesions at a given time point. Its score ranges from 0 to 5. BSA covered is reported as percent of body surface area covered. Total score for BSA x sPGA ranges from 0 to 500 with higher scores indicating greater severity.

  16. Improvement From Baseline in Work Productivity Measured by Change in Work Productivity and Activity Impairment Scale Over Time

    Time frame: baseline, weeks 16, 28, 40, 52, 64

    The WPAI is a validated, subject-reported quantitative assessment of the amount of absenteeism, presenteeism and daily activity impairment attributable to general health or a specific health problem. WPAI surveys were analyzed based on published algorithms to determine the following: current employment status, absenteeism, presenteeism, total activity impairment , and total work productivity impairment. Each WPAI score is expressed as impairment percentages (0-100), with higher scores indicating greater impairment (worse outcomes).

The 14-item TSQM Version 1.4 is a reliable and valid instrument to assess patients' satisfaction with medication, providing scores on four scales - side effects, effectiveness, convenience and global satisfaction. The TSQM domain scores range from 0-100 with higher scores representing higher satisfaction on that domain
