Canadian Rheumatologists will be randomized to treat their participants with active Psoriatic Arthritis to a target (disease activity score <2.6), or as per their routine care. The aim of this study is to determine whether treating to a target results in greater disease improvement than treating patients using routine care.

Condition Intervention
Psoriatic Arthritis (PsA)
Other: Intensive Care

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Subject)
Primary Purpose: Supportive Care
Official Title: A Trial of Active Psoriatic Arthritis (PsA): Randomizing to Treat to a Target vs. Usual Care

Primary Outcome Measures:
  • Percentage of patients achieving low DAS [ Time Frame: Month 9 Visit ]
    The primary outcome measure will be the percentage of patients achieving low Disease Activity Score (DAS<2.6) in each patient group (Intensive Care vs. Routine Care) at the end of the study.

Secondary Outcome Measures:
  • Time to achieving DAS28<2.6 [ Time Frame: Month 3 Visit, Month 6 Visit, and Month 9 Visit ]
    Compares the effectiveness of Intensive Care and Routine Care groups, as measured by the time to achieving target of DAS28<2.6

  • Absolute change in DAS28 [ Time Frame: Month 3 Visit, Month 6 Visit, Month 9 Visit ]
    To compare the effectiveness of Intensive Care and Routine Care in improving the patient DAS28.

  • Percentage of Patients achieving ACR 20, 50, and 70 [ Time Frame: Month 3 Visit, Month 6 Visit, Month 9 Visit ]

    ACR 20/50/70 defined as:

    • 20%, 50%, or 70% reduction in tender joint count, and
    • 20%, 50%, or 70% reduction in swollen joint count, and
    • a 20%, 50%, or 70% reduction in 3 of the following 5 measures:
    • Patient and physician global assessments (VAS)
    • Patient pain score (VAS)
    • HAQ-DI
    • ESR or CRP

  • Percentage of patients achieving PsARC [ Time Frame: Month 3 Visit, Month 6 Visit, Month 9 Visit ]

    PsARC defined as improvement in at least 2 of the 4 following measures, one of which must be joint swelling or tenderness, and no worsening in any of the 4 measures:

    • MDGA (0-5 point scale): reduction by 1 point.
    • PGA (0-5 point scale): reduction by 1 point.
    • TJC (76 or 68): reduction by >=30%.
    • SJC (76 or 68): reduction by >=30%.

  • Absolute change in HAQ-DI [ Time Frame: Month 3 Visit, Month 6 Visit, Month 9 Visit ]
    HAQ-DI is a self-administered questionnaire using the patient's functional ability during the last week. It consists of 20 items converging to 8 scales measuring dressing and grooming, arising, eating, walking, hygiene, reach, grip and common daily activities. The patients rate each activity as 0 = without any difficulty, 1 = some difficulty, 2 = much difficulty and 4 = unable. The final score ranges from 0 to 3 with higher scores indicating more disability.

Estimated Enrollment: 230
Study Start Date: October 2012
Estimated Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Intensive Care (IC)
Rheumatologists treating to target of DAS28<2.6
Other: Intensive Care
Rheumatologist aims to treat participant in order to achieve a disease activity score improvement of DAS28<2.6
No Intervention: Routine Care (RC)
Participants treated in the routine manner by their rheumatologist (not treated to the target of DAS28<2.6)


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Psoriatic Arthritis as diagnosed by a rheumatologist and meeting ACR classification criteria for PsA or CASPAR criteria
  • The subject must provide written informed consent for participation in the study before any study specific procedures are performed
  • Subject has 3 or more SJC on 28 joint count
  • Age >=18

Exclusion Criteria:
