Brief Summary:
The purpose of this study is to evaluate the efficacy, safety and tolerability of guselkumab in participants with Active Psoriatic Arthritis (PsA).

Condition or disease Intervention/treatment Phase
Psoriatic Arthritis Drug: Guselkumab Drug: Ustekinumab Drug: Placebo Phase 2

Detailed Description:
This is a multi-center (more than one clinical site will work on a medical research study), randomized (study medication assigned to participants by chance), double-blind (neither investigator nor participant knows which treatment the participant receives), placebo-controlled (placebo is an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial) study to determine the efficacy and safety of guselkumab in participants with PsA. The study will consist of 4 parts: Screening period (6 weeks), a double-blind treatment period (consists of guselkumab and placebo treatment for 24 weeks), an active treatment period (guselkumab for 20 weeks), and follow-up period (12 weeks). The maximal study duration for a participant will not exceed 62 weeks including the Screening period. Eligible participants will be randomly assigned to one of two groups in a 2:1 ratio to either receive Guselkumab 100 milligram (mg) at Weeks 0, 4 then every 8 weeks or Placebo at Weeks 0, 4 then every 8 weeks until Week 24. At week 24, participants remaining in the placebo group will start to receive guselkumab 100 mg at Weeks 24, 28, 36 and 44. Participants in both treatment groups who have less than (<) 5 percent (%) improvement from baseline in both tender and swollen joint counts at Week 16 will qualify for early escape and will switch to open-label therapy with ustekinumab 45 mg or 90 mg at Weeks 16, 20, 32, and 44 based on the approved dosage for the PsA indication in the particular country of study. The efficacy will be assessed primarily by measuring percentage of participants who achieve an American College of Rheumatology (ACR) 20 Response at Week 24. Participants' safety will be monitored throughout the study.

Treatment Failure (TF) criteria: Discontinued study drug due to lack of efficacy or worsening of PsA, initiated or increased dose of methotrexate or oral corticosteroids, or initiated prohibited PsA treatments. FAS is full analysis set.


Secondary Outcome Measures :
  1. Percentage of Participants Who Achieved a Psoriasis Area and Severity Index (PASI)-75 Response at Week 24 [ Time Frame: Week 24 ]
    The PASI is a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In the PASI system, the body is divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas is assessed separately for the percentage of the area involved, which translates to a numeric score that ranges from 0 (indicates no involvement) to 6 (90 percentage (%)-100% involvement), and for erythema, induration and scaling, which are each rated on a scale of 0 to 4. The PASI produces a numeric score that could range from 0 (no psoriasis) to 72 (worst condition). PASI 75 response was defined as at least a 75% reduction in PASI relative to Baseline. As planned, results data was analyzed and reported for the specified arms for this outcome measure.

The mCPDAI scores were calculated using the following assessments: joints (66 swollen and 68 tender joint counts), HAQ-DI score, PASI, dactylitis, and enthesitis. Within each domain a score (range 0-3) was assigned, where 0= Not involved, 1= Mild, 2= Moderate and 3= Severe. The scores for each domain were then added together to give a final score range of 0 to 12. A higher score indicates more active disease activity. Negative changes from baseline indicate improvement of PsA disease activity.

  28. Change From Baseline in mCPDAI Index Score at Weeks 24 and 44 [ Time Frame: Baseline and Weeks 24, 44 ]
    The mCPDAI assessed 4 domains (joints, skin, entheses, and dactylitis). The mCPDAI scores were calculated using the following assessments: joints (66 swollen and 68 tender joint counts), HAQ-DI score, PASI, dactylitis, and enthesitis. Within each domain a score (range 0-3) was assigned, where 0= Not involved, 1= Mild, 2= Moderate and 3= Severe. The scores for each domain were then added together to give a final score range of 0 to 12. A higher score indicates more active disease activity. Negative changes from baseline indicate improvement of PsA disease activity.

  29. Change From Baseline in Disease Activity Index for Psoriatic Arthritis (DAPSA) Score at Weeks 4, 8, 12, 16, 20 and 24 [ Time Frame: Baseline and Weeks 4, 8, 12, 16, 20, 24 ]
    Change from baseline in DAPSA measures the change in disease activity, where a negative change indicates an improvement and a positive change indicates worsening of disease activity. DAPSA score is a the sum of swollen joint count (66 joints), tender joint count (68 joints), CRP (mg/dL), Patient's Assessment of Pain (on a 10-unit VAS;0=no pain, 10=worst possible pain), and Patient's Global Assessment of Disease Activity (arthritis, on a 10-unit VAS; 0 to 100 centimeter [cm] VAS, 0=excellent and 10=poor). Cut-off values for disease activity: 0-4 remission; 5-14 low; 15-28 moderate; >28 high.

  30. Change From Baseline in DAPSA Index Score at Weeks 24, 28, 32, 36, 44, and 56 [ Time Frame: Baseline and Weeks 24, 28, 32, 36, 44, 56 ]
    Change from baseline in DAPSA measures the change in disease activity, where a negative change indicates an improvement and a positive change indicates worsening of disease activity.

Cut-off values for disease activity: 0-4 remission; 5-14 low; 15-28 moderate; >28 high.

  31. Percentage of Participants Who Achieved Minimal Disease Activity (MDA) at Weeks 16 and 24 [ Time Frame: Weeks 16 and 24 ]
    MDA defines a satisfactory state of disease activity that includes 5 domains of PsA (joint symptoms, skin psoriasis, patient's perspective of pain and disease activity on arthritis and psoriasis, physical function and enthesitis). Participants were classified as achieving MDA if they fulfilled 5 of 7 outcome measures: tender joint count <=1; swollen joint count <=1; PASI <=1; patient pain VAS score of <=15 mm; patient global disease activity on arthritis and psoriasis; VAS score of <=20 mm; Health Assessment Questionnaire score <=0.5; and tender entheseal points <=1.

    SF-36 is a multi-domain instrument with 36 items to evaluate the health status and quality of life. It included 8 subscales (physical functioning, physical role functioning, bodily pain, general health perception, vitality, social functioning, emotional role functioning, and mental health), which yielded a Physical Component Summary (PCS) with score range 0-100 (higher score-better quality of life) and a Mental Component Summary (MCS) with score range 0-100 (higher score-better quality of life) in addition to subscale scores. The PCS and MCS scores are normalized to a mean of 50 and standard deviations of 10, based upon general US population norms as presented in this outcome measure. A positive change indicates improvement while a negative change indicates worsening of health status and quality of life.

    SF-36 evaluates 8 individual subscales (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health). Each 8 scales scored from 0 to 100 with higher scores= better health. The scores are normalized to a mean of 50 and standard deviations of 10, based upon general US population norms. Higher scores indicate better health. A positive change indicates improvement while a negative change indicates worsening of health status and quality of life.

  40. Percentage of Participants Who Achieved a PASI 50, PASI 75, PASI 90 and PASI 100 Response at Weeks 16 and 24 [ Time Frame: Weeks 16 and 24 ]
    The PASI is a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In the PASI system, the body is divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas is assessed separately for the percentage of the area involved, which translates to a numeric score that ranges from 0 (indicates no involvement) to 6 (90 percentage (%)-100% involvement), and for erythema, induration and scaling, which are each rated on a scale of 0 to 4. The PASI produces a numeric score that could range from 0 (no psoriasis) to 72. PASI 50, 75, 90, and 100 responses were defined as at least a 50%, 75%, 90%, and 100% reduction in PASI relative to Baseline respectively. As planned, results data was analyzed and reported for the specified arms for this outcome measure.
