Detailed Description

This is a study of guselkumab in participants with active PsA who are biologically naive and have had inadequate response to standard therapies. It will evaluate the clinical efficacy of guselkumab in the reduction of signs and symptoms, structural damage inhibition and the safety profile of guselkumab in the treatment of PsA. The study will consist of a screening phase (up to 6 weeks), a blinded treatment phase (approximately 100 weeks) including a placebo controlled period from Week 0 to Week 24 and an active treatment period from Week 24 to Week 100 and a safety follow-up phase of 12 weeks after the last administration of study agent. Efficacy, health economics, safety, pharmacokinetics, immunogenicity, biomarker and pharmacogenomics evaluations will be performed in the study at defined schedule.

Percentage of Participants Who Achieved an American College of Rheumatology (ACR) 20 Response at Week 24
Time Frame: Week 24
ACR 20 response: >=20% improvement from baseline in both swollen joint count (66 joints) and tender joint count (68 joints), and >=20% improvement from baseline in 3 of 5 assessments: patient's assessment of pain using visual analog scale (VAS; 0-100 mm, 0=no pain and 100=worst possible pain), patient's global assessment of disease activity (arthritis, VAS; 0-100 mm, 0=excellent and 100= poor), physician's global assessment of disease activity (VAS; 0-100 mm, 0=no arthritis activity and 100=extremely active arthritis), patient's assessment of physical function measured by Disability Index of Health Assessment Questionnaire (HAQ-DI; 20-question instrument assessing 8 functional areas; range: 0-3, 0= no difficulty, 3= inability to perform task in that area), and CRP. Treatment Failure (TF) criteria- discontinued study drug, initiated/increased dose of non-biologic disease-modifying antirheumatic drugs (DMARDs) or oral corticosteroids, initiated prohibited psoriatic arthritis treatment.
Week 24

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) Score at Week 24
Time Frame: Baseline and Week 24
HAQ-DI score assess functional status of participant. It is 20 question instrument that assess degree of difficulty a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and activities of daily living). Responses in each functional area were scored from 0=indicating no difficulty, to 3=indicating inability to perform a task in that area. Total HAQ score is average of the computed categories scores ranging from 0-3 where 0=least difficulty and 3=extreme difficulty. Lower scores are indicative of better functioning. Negative change from baseline indicates improvement of physical function.
Baseline and Week 24
Percentage of Participants Who Achieved an ACR 50 Response at Week 24
Time Frame: Week 24
ACR 50 response was defined as greater than or equal to (>=)50 percent (%) improvement from baseline in both swollen joint count (66 joints) and tender joint count (68 joints), and >=50% improvement from baseline in 3 of 5 assessments: patient's assessment of pain using visual analog scale (VAS; 0-100 mm, 0=no pain and 100=worst possible pain), patient's global assessment of disease activity (arthritis, VAS; 0-100 mm, 0=excellent and 100= poor), physician's global assessment of disease activity (VAS; 0-100 mm, 0=no arthritis activity and 100=extremely active arthritis), patient's assessment of physical function measured by Disability Index of the Health Assessment Questionnaire (HAQ-DI; a 20-question instrument assessing 8 functional areas; range: 0-3, 0=no difficulty, 3=inability to perform a task in that area), and C-Reactive Protein (CRP).
Week 24
Percentage of Participants Who Achieved Psoriasis Response With IGA Score of 0 (Cleared) or 1 (Minimal) and >=2 Grade Reduction From Baseline at Week 24 Among Participants With >=3% BSA Psoriatic Involvement and IGA Score of >=2 (Mild) at Baseline
Time Frame: Week 24
A psoriasis Investigator's Global Assessment (IGA) response was defined as an IGA score of 0 (cleared) or 1 (minimal) and >=2 grade reduction from baseline in the IGA psoriasis score. The IGA documents the investigator's assessment of the patient's psoriasis and lesions are graded for induration, erythema and scaling, each using a 5 point scale: 0 (no evidence), 1 (minimal), 2 (mild), 3 (moderate), and 4 (severe). The IGA score of psoriasis was based upon the average of induration, erythema and scaling scores. The participant's psoriasis was assessed as cleared (0), minimal (1), mild (2), moderate (3), or severe (4).

Time Frame: Baseline and Week 24
Modified vdH-S score is the sum of the erosion score (hand, feet) and joint space narrowing (JSN) score (hand, feet). Joint erosion score is the summary of erosion severity in 40 joints of hand scored according to the surface area, from 0 (no erosion) to 5 (complete collapse of bone) and 12 joints of 2 feet (each side of the foot joint is graded on same 0-5 scale, thus maximum erosion score for a foot joint is 10), for a maximum erosion score of 320. JSN score is the total JSN score in same 52 joints as above, each joint scored according to the subluxation from 0 (normal) to 4 (bony ankylosis or complete luxation), for a maximum JSN score of 208. Total score ranges from 0 (best) to 528 (worst = worst possible erosion score of 320 + worst possible JSN score of 208). Higher score indicates more joint damage. Positive changes from baseline in the modified vdH-S total, erosion and JSN scores indicate progression of joint damage.

DAPSA assessed the joint domain of PsA and was derived from the sum of the following components: tender joint count (0-68), swollen joint count (0-66), CRP level (mg/dL, value <lower limit of quantification [LLOQ] is considered equal to half of the value of LLOQ for numerical calculations), patient assessment of pain (0-10cm VAS, 0=no pain, 10=worst possible pain), and patient's global assessment of disease activity on arthritis (0 to 10cm VAS, 0=excellent and 10=poor). A higher score indicates more active disease activity. Negative changes from baseline indicate improvement of PsA disease activity. The assessment does not have a score range with an upper or lower bound.

Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) is a self-assessment tool that consists of 6 questions relating to the 5 major symptoms of ankylosing spondylitis: fatigue, spinal pain, joint pain, enthesitis, qualitative morning stiffness and quantitative morning stiffness. The first 5 items were scored on a 10 centimeter (cm) VAS ranging from 0=none to 10=very severe. Quantitative morning stiffness was scored on a 10cm VAS ranging from 0=0 hours to 10=2 or more hours. The 2 scores for qualitative and quantitative morning stiffness were averaged, and the total BASDAI score was the average of the 5 scores of each symptom, ranging from 0 (none) to 10 (very severe). Higher scores indicate greater disease severity and an improvement of 50% from baseline is considered clinically meaningful. Only participants with spondylitis and peripheral arthritis as their primary arthritic presentation of PsA completed the BASDAI indicate the degree of their symptoms over the past week.

EQ-5D-5L is a 2-part instrument for use as a measure of health outcome, designed for self-completion by respondents. It consists of EQ-5D-5L descriptive system and EQ VAS. The EQ VAS self-rating records the respondent's own assessment of his or her overall health status at the time of completion, on a vertical line VAS with scale of 0 (the worst health you can imagine) to 100 (the best health you can imagine). A higher score indicates better health and positive changes from baseline indicate improvement of health status.

Change From Baseline in EQ-5D-5L at Weeks 24 and 52: EQ-5D Index
Time Frame: Baseline, Weeks 24 and 52
EQ-5D-5L is a 2-part instrument for use as a measure of health outcome, designed for self-completion by respondents. It consists of EQ-5D-5L descriptive system and EQ VAS. EQ-5D-5L descriptive system comprises of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each has 5 levels of perceived problems (1-no problem, 2-slight problems, 3-moderate problems, 4-severe problems, 5-extreme problems). Participant selects answer for each of 5 dimensions considering response that best matches his/her health "today". Responses were used to generate a weighted summary index (EQ-5D index), which ranges from 0 (dead) to 1.00 (full health). A higher score indicates better health and positive changes from baseline indicate improvement of health.

Percentage of Participants Without Radiographic Modified vdH-S Progression Based on (SDC) From Baseline to Week 100
Time Frame: Baseline to Week 100
Modified vdH-S score is the sum of the erosion score (hand, feet) and JSN score (hand, feet). Joint erosion score is the summary of erosion severity in 40 joints of hand scored according to the surface area, from 0 (no erosion) to 5 (complete collapse of bone) and 12 joints of 2 feet (each side of foot joint is graded on same 0-5 scale, thus maximum erosion score for a foot joint is 10), for a maximum erosion score of 320. JSN score is the total JSN score in same 52 joints as above, each joint scored according to the subluxation from 0 (normal) to 4 (bony ankylosis or complete luxation), for a maximum JSN score of 208. Total score ranges from 0 (best) to 528 (worst = worst possible erosion score of 320 + worst possible JSN score of 208). Higher score indicates more joint damage. SDC was defined as the cut-off above which the changes can be detected beyond measurement error. Without radiographic progression was defined as change from baseline in the modified vdH-S score <=SDC of 3.46.

Change From Baseline in Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Score at Weeks 52, 76 and 100
Time Frame: Baseline, Weeks 52, 76 and 100
The FACIT-Fatigue is a questionnaire that assesses self-reported tiredness, weakness, and difficulty conducting usual activities due to fatigue. The subscale consists 13-item instrument to measure fatigue. Each of the 13 items has a set of five response categories: Not at all (=0), A little bit (=1), Somewhat (=2), Quite a bit (=3) and Very much (=4). A total FACIT-Fatigue subscale score was calculated as the sum of the 13 item scores (reserved scores [4 - score]) and ranges from 0 to 52, with a higher score indicating less fatigue. Positive changes from baseline indicate improvement of fatigue. Items were reverse scored when appropriate to provide a scale in which higher scores represent better functioning or less fatigue.

Change From Baseline in EQ-5D-5L at Weeks 52, 76 and 100: EQ-5D Index
Time Frame: Baseline, Weeks 52, 76 and 100
EQ-5D-5L is a 2-part instrument for use as a measure of health outcome, designed for self-completion by respondents. It consists of EQ-5D-5L descriptive system and EQ VAS. EQ-5D-5L descriptive system comprises of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each has 5 levels of perceived problems (1-no problem, 2-slight problems, 3-moderate problems, 4-severe problems, 5-extreme problems). Participant selects answer for each of 5 dimensions considering response that best matches his/her health "today". Responses were used to generate a weighted summary index (EQ-5D index), which ranges from 0 (dead) to 1.00 (full health). A higher score indicates better health and positive changes from baseline indicate improvement of health.

Change From Baseline in WPAI Scores (Percent Work Time Missed) at Weeks 52, 76 and 100
Time Frame: Baseline, Weeks 52, 76 and 100
Work Productivity and Activity Impairment was assessed using the Work Productivity and Activity Impairment Questionnaire - Specific Health Problem (WPAI-SHP) of PsA (WPAI-PsA). The WPAI-PsA consisted of 6 questions to determine employment status, hours missed from work due to PsA, hours missed from work for other reasons, hours actually worked, the degree to which PsA affected work productivity while at work and the degree to which PsA affected activities outside of work during the past 7 days. WPAI outcomes included percent work time missed due to PsA, percent impairment while working due to PsA, percent overall work impairment due to PsA, and percent activity impairment outside of work due to PsA. These WPAI outcomes were expressed as impairment percentages (0-100, 0=no impairment and 100=100% impaired), with higher numbers indicating greater impairment and less productivity. Negative changes from baseline indicate improvement of work productivity and activity impairment.
