A Study Evaluating the Efficacy and Safety of Guselkumab Administered Subcutaneously in Participants With Active Psoriatic Arthritis Including Those Previously Treated With Biologic Anti -Tumor Necrosis Factor (TNF) Alpha Agent(s)

Janssen Research & Development, LLC383 enrolled

Overview

The primary purpose of this study is to evaluate the efficacy of guselkumab treatment in participants with active Psoriatic Arthritis (PsA) by assessing the reduction in signs and symptoms of PsA.

This is a study of guselkumab in participants with active Psoriatic Arthritis (PsA) who had inadequate response to standard therapies. It will evaluate the clinical efficacy of guselkumab in the reduction of signs and symptoms and the safety profile of guselkumab in the treatment of PsA. The study will consists of 4 phases: a screening phase of up to 6 weeks, a blinded treatment phase of approximately 1 year (that is, 52 weeks), including a placebo controlled period from Week 0 to Week 24 and double-blind active treatment period from Week 24 to Week 52, and a safety follow-up phase of 8 weeks after Week 52 (Week 52 to 60) and will be 12 weeks from the last administration of study agent (at Week 48) to the final safety follow-up visit. Efficacy, safety, pharmacokinetic, immunogenicity, and biomarker evaluations will be performed in the study at defined schedule.

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 with peripheral arthritis as their primary arthritic presentation of PsA completed the BASDAI indicate the degree of their symptoms over the past week.

PASI is a tool to assess and grade severity of psoriasis and response to therapy. In PASI, body is divided into 4 areas: head, trunk, upper extremities, lower extremities. Each area was assessed separately for percentage of area involved and translated to numeric score ranging from 0 (no involvement) to 6 (90 to 100% involvement), and for erythema, induration, and scaling, each rated on scale of 0 to 4 that is none to maximum severity. PASI numeric score range from 0 (no psoriasis) to 72. Higher scores indicate more severe disease. Negative changes from baseline indicate improvement of psoriasis.

Percentage of Participants Who Achieved >=5 Point Improvement From Baseline in SF-36 PCS Score at Weeks 24, 36 and 52

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 scores are normalized to a mean of 50 and standard deviations of 10, based upon general US population norms. Higher score indicates better outcome, with an increase of 5 points considered to be clinically meaningful.

Change From Baseline in Group of Research and Assessment of Psoriasis and Psoriatic Arthritis Composite (GRACE) Score Index at Weeks 24 and 52

GRACE index is a composite PsA disease activity score converted from AMDF, which was derived from TJC (0-68) and SJC (0-66), HAQ-DI (0-3), patient's global assessment of disease activity on arthritis and psoriasis (0-100 mm, 0=excellent and 100= poor), patient's assessment of skin disease activity (0-100 mm, 0=excellent and 100=poor), patient's global assessment of disease activity on arthritis (0-100 mm, 0=excellent and 100=poor), PASI (0-72), and PsA Quality of Life Index (derived as PsAQOL =25.355 + \[2.367\*HAQ-DI\] - \[0.234\*SF-PCS\] - \[0.244\*SF-MCS\]), where HAQ-DI: HAQ-DI score (0-3, 0=least difficulty and 3=extreme difficulty), SF-PCS (Score ranges from 0 to 100, higher scores= better quality of life) and SF-MCS (score ranges from 0 to 100, higher scores= better quality of life). The total score is from 0-10, where lower score indicates better response. Higher score indicates more active disease activity. Negative change from baseline indicates improvement of PsA disease activity.

Percentage of Participants With Resolution of Enthesitis at Weeks 24, 36, 44 and 52 Among the Participants With Enthesitis at Baseline

Enthesitis was assessed using the LEI, a tool developed to assess enthesitis in participants with PsA and evaluates the presence (score of 1) or absence (score of 0) of pain by applying local pressure to the following entheses: left and right lateral epicondyle humerus, left and right medial femoral condyle, and left and right achilles tendon insertion. The enthesitis index score is a total score of the 6 evaluated sites from 0 (0 sites with tenderness) to 6 (worst possible score; 6 sites with tenderness). A LEI score of 0 at a post baseline visit indicates resolution of enthesitis when baseline LEI\>0.

Change From Baseline in Enthesitis Score (Based on SPARCC) at Weeks 24, 36, 44 and 52 Among the Participants With Enthesitis at Baseline

Enthesitis was assessed using the Spondyloarthritis Research Consortium of Canada (SPARCC). The SPARCC developed a measure for enthesitis in general spondyloarthritis which evaluates the presence or absence of pain by applying local pressure to the following entheses: supraspinatus insertion (left and right), medial epicondyle humerus (left and right), lateral epicondyle humerus (left and right), greater trochanter (left and right), quadriceps-to-patella (left and right), patellar-tibia (left and right), achilles tendon insertion (left and right), plantar fascia (left and right). Tenderness on examination was recorded as either present (1) or absent (0) for each of the 16 sites for an overall score range of 0-16. Higher scores indicate more severe enthesitis. Negative changes from baseline indicate improvement of enthesitis.

Percentage of Participants With an IGA Score of 0 (Cleared) or 1 (Cleared) at Weeks 24 and 52 Among Participants With >=3% BSA Psoriatic Involvement and an IGA Score of >=2 at Baseline

A psoriasis 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).
