| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Percentage of Participants Simultaneously Achieving American College of Rheumatology 50 (ACR50) and Psoriasis Area and Severity Index 100 (PASI100) | Week 24 | ACR50 response is a ≥50% improvement from baseline for tender joint count(TJC)\& swollen joint count (SJC)\& in at least 3 of the following 5 criteria: Participant's(pts) assessment of joint pain Visual Analog Scale (VAS),Pts Global Assessment of Disease Activity (PatGA)VAS, Physician's Global Assessment of Disease Activity (PGA)VAS, Pts assessment of physical function using the Health Assessment Questionnaire-Disability Index(HAQ-DI), or High Sensitivity(assay)C-Reactive Protein (hs-CRP). PASI is an index combining assessments of the extent of body-surface involvement in head, trunk, arms, legs, and severity of desquamation, erythema and plaque thickness in each region, yielding overall score of 0-no involvement, to 72-most severe involvement. Pts achieving PASI100 were defined as having 100% improvement in the PASI score compared to baseline. Pts with active plaque PsO with a BSA≥3% \& PASI=0 at baseline were considered PASI100 responders if they had achieved PASI=0 \& BSA=0 at week 24. |
| Secondary | Percentage of Participants Achieving ACR50 | Week 24 | ACR50 response is defined as a ≥50% improvement from baseline for tender joint count (TJC) and swollen joint count (SJC) and in at least 3 of the following 5 criteria: Participant's assessment of joint pain Visual Analog Scale (VAS), Participant's Global Assessment of Disease Activity (PatGA) VAS, Physician's Global Assessment of Disease Activity (PGA) VAS, participant's assessment of physical function using the Health Assessment Questionnaire-Disability Index (HAQ-DI), or High Sensitivity (assay) C-Reactive Protein (hs-CRP). |
| Secondary | Percentage of Participants Achieving PASI100 | Week 24 | PASI is an index combining assessments of the extent of body-surface involvement in head, trunk, arms, legs, and severity of desquamation, erythema and plaque thickness in each region, yielding overall score of 0-no involvement, to 72-most severe involvement. Participants achieving PASI100 were defined as having 100% improvement in the PASI score compared to baseline. Any participants with active plaque psoriasis (PsO) with a BSA ≥3% and PASI = 0 at baseline were considered PASI100 responders if \& only if they had achieved PASI=0 \& BSA=0 at week 24. |
| Other | Change From Baseline in Tender Joint Count (TJC) | Baseline, Week 52 | TJC is the number of tender and painful joints determined for each participant by examination of 68 joints. Joints were assessed by pressure and joint manipulation on physical examination. Participants were asked for pain sensations on these manipulations and watched for spontaneous pain reactions. Any positive response on pressure, movement, or both was translated into a single tender-versus-nontender dichotomy. Least Square(LS) Mean was calculated using Mixed Model Repeated Measures (MMRM) model that included treatment group, concomitant conventional synthetic disease-modifying anti-rheumatic drugs (csDMARD) use at baseline, moderate-to-severe plaque psoriasis involvement, visit as fixed factors, baseline value as covariate and baseline-by-visit and treatment-by-visit interactions terms. |
| Other | Change From Baseline in Swollen Joint Count (SJC) | Baseline, Week 52 | SJC is the number of swollen joints determined for each participant by examination of 66 joints. Joints were classified as either swollen or not swollen. Swelling was defined as palpable fluctuating synovitis of the joint. LS mean was calculated using MMRM model that included treatment group, concomitant conventional synthetic disease-modifying anti-rheumatic drugs (csDMARD) use at baseline, moderate-to-severe plaque psoriasis involvement, visit as fixed factors, baseline value as covariate and baseline-by-visit and treatment-by-visit interactions terms. |
| Other | Change From Baseline in Participant's Assessment of Pain Visual Analogue Score (VAS) | Baseline, Week 52 | The pain VAS is a participant-administered single-item scale designed to measure current joint pain from Psoriatic arthritis (PsA) using a 100-millimeter(mm) horizontal VAS. Overall severity of participant's joint pain from PsA is indicated by marking a vertical tick on the horizontal 100-mm scale, where the left end from 0 mm (no pain) to right end 100 mm (worst possible joint pain). LS mean was calculated using MMRM model that included treatment group, concomitant csDMARD use at baseline, moderate-to-severe plaque psoriasis involvement, visit as fixed factors, baseline value as covariate and baseline-by-visit and treatment-by-visit interactions terms. |
| Other | Change From Baseline in Participant's Global Assessment of Disease Activity | Baseline, Week 52 | The patient's overall assessment of his or her PsA activity was recorded using a 100-mm horizontal VAS, where 0 represents no disease activity and 100 represents extremely active disease. LS mean was calculated using MMRM model that included treatment group, concomitant csDMARD use at baseline, moderate-to-severe plaque psoriasis involvement, visit as fixed factors, baseline value as covariate and baseline-by-visit and treatment-by-visit interactions terms. |
| Other | Change From Baseline in Physician's Global Assessment of Disease Activity | Baseline, Week 52 | The investigator was asked to give an overall assessment of the severity of the participant's current PsA activity using a 100-mm horizontal VAS, where 0 represents no disease activity and 100 represents extremely active disease. LS mean was calculated using MMRM model that included treatment group, concomitant csDMARD use at baseline, moderate-to-severe plaque psoriasis involvement, visit as fixed factors, baseline value as covariate and baseline-by-visit and treatment-by-visit interactions terms. |
| Other | Change From Baseline in C-Reactive Protein (CRP) | Baseline, Week 52 | CRP is the ACR Core Set laboratory measure of acute-phase reactant. It was measured with a high sensitivity assay at the central laboratory to help assess the effect of ixekizumab on the participant's PsA. LS mean was calculated using MMRM model that included treatment group, concomitant csDMARD use at baseline, moderate-to-severe plaque psoriasis involvement, visit as fixed factors, baseline value as covariate and baseline-by-visit and treatment-by-visit interactions terms. |
| Other | Change From Baseline in HAQ-DI | Baseline, Week 52 | HAQ-DI is a participant reported questionnaire that measures disease-associated disability (physical function). It consists of 24 questions with 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and other daily activities. The disability section scores the participant's self-perception on the degree of difficulty (0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, and 3 = unable to do), covering the 8 domains. The reported use of special aids or devices and/or the need for assistance of another person to perform these activities is assessed. The HAQ-DI is a composite ranging from 0-3 with lower scores indicating less functional disability. LS mean was calculated using MMRM model that included treatment group, concomitant csDMARD use at baseline, moderate-to-severe plaque psoriasis involvement, visit as fixed factors, baseline value as covariate and baseline-by-visit and treatment-by-visit interactions terms. |
