ListOutcomeTime frameDescription
PrimaryPresence of MDA (minimal disease activity) 12 months after baseline.12 months
The MDA status comprises the assessment of different domains of PsA, consisting of the following individual components: * swollen and tender joint count * tender entheseal point count * skin involvement (PASI)patient self-assessment of pain (VAS) * global disease activity status * subject's self-assessment of functional ability using Stanford Health Assessment Questionnaire disability index, (HAQ-DI) MDA is defined as the presence of 5 of the following 7 criteria: 1. tender joint count ≤1 2. swollen joint count ≤1 3. tender entheseal point count ≤1 (means: remission) 4. PASI ≤1 OR body surface area (BSA) ≤3% 5. patient pain VAS ≤15 6. patient global activity VAS ≤20 7. HAQ-DI ≤0.5
SecondaryKey secondary endpoint: PASDAS (Psoriatic Arthritis Disease Activity Score)12 months
The PASDAS is a composite disease activity index (range 0-10) for psoriatic arthritis (PsA) incorporating seven domains: patient and physician global activity VAS scores, tender and swollen joint counts (arthritis), dactylitis, enthesitis (Leeds), health-related QoL (SF-36), and CRP level. PASDAS has demonstrated to have a better discriminate capacity in distinguishing high and low disease activity. The PASDAS is computed by the following equation: PASDAS = (((0, 18 ∗ ∗√(PhGA) + 0.159 ∗ ∗√(PtGA) - 0.253 ∗ ∗√(SF36 -PCS) + 0.101 ∗ lognat(SJC66 + 1)) + 0.048 ∗ lognat(SJC68 +1)) + 0.23 ∗ lognat (Leeds enthesitis index + 1)) + 0.37 ∗lognat (tender dactylitis count + 1) + 0.102 ∗ lognat (CRP +1) + 2 ∗ 1.5.
SecondaryKey secondary endpoint: DAPSA (Disease Activity in PSoriatic Arthritis)12 months
The DAPSA score determines changes in the disease activity of subjects diagnosed with PsA. DAPSA is a composite score which is calculated from the sum of: number of tender joints (0-68), number of swollen joints (0-66, hips are not taken into account), CRP (mg/dl), subject's assessment of global status of disease activity using VAS (0-10) and patient's self-assessment of pain using VAS (0-10). A value of the composite score DAPSA 0-≤ 4 marks remission, 5-14 marks low, 15-28 moderate and \>28 high disease activity
SecondaryKey secondary endpoint: CPDAI (Composite Psoriatic Disease Activity Index)12 months
The composite psoriatic disease activity index (CPDAI) assesses disease activity under five domains using well established and validated instruments of PsA disease documentation as proposed by GRAPPA. The domains and the respective instrument are as follows: joint disease (SJC/TJC, HAQ), skin involvement (PASI, DLQI), enthesitis (LEI, HAQ), dactylitis (dactylitis digit count, HAQ) and spinal involvement (BASDAI and ASQoL). Using the instruments and ranges of values, disease activity under each domain is graded as none (0) -mild (1) -moderate (2) and severe (3) giving a range attainable CPDAI scores of between 0 and 15. The CPDAI correlates well with patient and physician global disease activity assessments and is an effective tool that clearly distinguishes those who require a treatment change from those who do not.
SecondaryNumber of swollen and tender joints12 monthsAn assessment of 66 joints for swelling and 68 joints for tenderness will be made (including the DIP joints of the hands and excluding hips for swelling).
SecondaryNumber of tender entheseal points: SPARCC (Spondyloarthritis Consortium of Canada)12 months
The SPARCC enthesitis score is based on the counting of the presence or absence of tenderness on 16 entheseal sites (eight sites on each body side, respectively): lateral epicondyle, medial epicondyle, supraspinatus insertion into greater tuberosity of humerus, greater trochanter, quadriceps insertion into superior borders of patella, patellar ligament insertion into inferior pole of patella or tibial tubercle, Achilles tendon insertion into calcaneum, and plantar fascia insertion into calcaneum. Tenderness on examination is recorded as either present (1) or absent (0) for each of the 16 sites, summarized in an overall score ranging from 0 to 16. A higher count represents a greater enthesitis burden
SecondaryNumber of tender entheseal Points: LEI (Leeds Enthesitis Index)12 months
The LEI includes 3 entheseal sites on each body side, respectively: lateral epicondyles, medial condyles of the femur, and Achilles tendons. Tenderness on examination is recorded as either present (1) or absent (0) for each of the 6 sites, for in an overall score ranging from 0 to 6. A higher count represents a greater enthesitis burden
SecondaryNumber of tender entheseal Points: MASES (Maastricht Ankylosing Spondylitis Enthesitis Score)12 months
The MASES includes 6 entheseal sites on each body side (first costochondral joints, seventh costochondral joints, posterior superior iliac spines, anterior superior iliac spines, iliac crests, proximal insertion of Achilles tendons) and in addition the fifth lumbar spinous process. Tenderness on examination is recorded as either present (1) or absent (0) for each of the 13 sites, for an overall score ranging from 0 to 13. A higher count represents a greater enthesitis burden
SecondaryDactylitis counts12 monthsThe presence of dactylitis will be assessed by counting the fingers/toes with dactylitis.
SecondaryActivity of psoriasis: PASI (Psoriasis Area and Severity Index)12 monthsPASI combines the assessment of the severity of lesions and the area affected into a single score ranging from 0 (no disease) to 72 (maximal disease).
