Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Work Productivity and Activity Impairment (WPAI) Questionnaire: Mean Percentage of Work Time Missed (Absenteeism) Up to Month 9
Time Frame: Baseline, Month 3, Month 6, Month 9
Absenteeism, presented as the mean percentage of work time missed due to PsA (as reported on the WPAI), and calculated as: 100*number of hours of work missed due to PsA / (number of hours of work missed due to PsA + number of hours worked). WPAI is a questionnaire used to evaluate lost productivity; scores are presented as percentages (multiplying the scores by 100), with 0% representing no impact on productivity and 100% representing complete impact on productivity.
Baseline, Month 3, Month 6, Month 9
WPAI Questionnaire: Mean Percentage of Impairment While Working Due to PsA (Presenteeism) Up to Month 9
Time Frame: Baseline, Month 3, Month 6, Month 9
Presenteeism (the extent to which PsA decreased productivity) is presented as the mean percentage of impairment while working due to PsA, and calculated as: 100*scale value of question 5 on the WPAI (between 0 and 10) / 10. WPAI is a questionnaire used to evaluate lost productivity; scores are presented as percentages (multiplying the scores by 100), with 0% representing no impact on productivity and 100% representing complete impact on productivity.
Baseline, Month 3, Month 6, Month 9
WPAI Questionnaire: Mean Percentage of Overall Work Productivity Impairment (OWPI) Due to PsA Up to Month 9
Time Frame: Baseline, Month 3, Month 6, Month 9
The mean percentage of OWPI due to PsA (based on the WPAI questionnaire) is presented, calculated as: Absenteeism (%) +[1- Absenteeism(%)*Presenteeism(%)]. WPAI is a questionnaire used to evaluate lost productivity; scores are presented as percentages (multiplying the scores by 100), with 0% representing no impact on productivity and 100% representing complete impact on productivity.
Baseline, Month 3, Month 6, Month 9
WPAI Questionnaire: Mean Percentage of Activity Impairment Due to PsA Up to Month 9
Time Frame: Baseline, Month 3, Month 6, Month 9
Activity impairment due to PsA (the extent to which PsA affected the ability to perform usual daily activities) is presented as the mean percentage of activity impairment, calculated as 100*scale value of WPAI question 6 (between 0 and 10) / 10. WPAI is a questionnaire used to evaluate lost productivity; scores are presented as percentages (multiplying the scores by 100), with 0% representing no impact on productivity and 100% representing complete impact on productivity.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Health Assessment Questionnaire Disability Index (HAQ-DI) Score Up to Month 9
Time Frame: Baseline, Month 3, Month 6, Month 9
The HAQ-DI is a participant-reported questionnaire. It consists of 20 questions referring to 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and daily activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task were summed and averaged to provide a total score ranging from 0 (no disability) to 3 (very severe, high-dependency disability).
Baseline, Month 3, Month 6, Month 9
Percentage of Participants With American College of Rheumatology 20%, 50%, 70% (ACR20, ACR50, ACR70) Response at Month 9
Time Frame: Month 9

A participant is an ACR20, ACR50, or ACR70 responder if the following 3 criteria for improvement from Baseline are met:

  • ≥ 20%, ≥ 50%, or ≥ 70% improvement in tender joint count;
  • ≥ 20%, ≥ 50%, or ≥ 70% improvement in swollen joint count; and
  • ≥ 20%, ≥ 50%, or ≥ 70% improvement in at least 3 of the 5 following parameters:

    • Physician's global assessment of disease activity
    • Participant's global assessment of disease activity

Disease Activity Score (DAS 28) Up to Month 9
Time Frame: Baseline, Month 3, Month 6, Month 9

The DAS28 is a validated index of arthritis disease activity. Twenty-eight tender joint counts, 28 swollen joint counts, C-reactive protein, and general health are included in the DAS28 score. Scores on the DAS28 range from 0 to 10, with higher scores indicating higher disease activity. Participants were classified according to their scores as below:

  • DAS28 > 5.1 = High disease activity
  • DAS28 < 3.2 = Low disease activity
  • DAS28 < 2.6 = Remission

This scale takes into account the sites (first costochondral joint, seventh costochondral joint, posterior superior iliac spine, anterior superior iliac spine, iliac crest, fifth lumbar spinous process and proximal insertion of the Achilles tendon) and they scored from 0 to 13. Minimum tenderness score was 0; maximum tenderness score was 13.
