A Study of Guselkumab and Golimumab Combination Therapy in Participants With Active Psoriatic Arthritis

Janssen Research & Development, LLC91 enrolled

Overview

The purpose of this study is to evaluate the efficacy of guselkumab plus golimumab combination treatment in participants with active psoriatic arthritis (PsA) and inadequate response (IR) to prior anti-tumor necrosis factor-alpha (anti-TNF-alpha) therapies by assessing clinical response compared with guselkumab monotherapy.

PsA is a chronic inflammatory multi-faceted disease that impacts the peripheral and axial joints, soft tissues, and skin. Guselkumab is a fully human monoclonal antibody (mAb) directed against the p19 subunit of interleukin (IL)-23, blocks the binding of extracellular IL-23 to the cell surface IL-23 receptor, inhibiting IL-23 specific intracellular signaling, subsequent activation, and cytokine production. Golimumab is a fully human anti-TNF-alpha mAb that binds to TNF-alpha with high affinity, prevents binding to its receptors, thereby inhibiting the biological activity of TNF-alpha and resulting in limited production or activity of inflammatory cytokines, thereby providing therapeutic benefit in various chronic inflammatory disorders, including PsA. This study will consist of a Screening Phase (up to 6 weeks), Double-blind Phase from Weeks 0 to 24 which includes the active treatment phase and the primary efficacy visit (Week 24), and Safety Follow-up Phase from Week 24 to Week 36. Key safety assessments will include adverse events (AEs), clinical laboratory safety tests (hematology and chemistry), vital signs, monitoring for injection-site and hypersensitivity reactions, and early detection of active tuberculosis (TB). The total duration of the study is up to 42 weeks.

Percentage of Participants Who Achieved Psoriasis Area and Severity Index (PASI) 90 Response at Week 24 Among Participants With >= 3% Body Surface Area (BSA) Psoriatic Involvement and an Investigator Global Assessment (IGA) Score of >=2 (Mild) at Baseline

PASI 90 response was defined as at least a 90% reduction in PASI relative to baseline. PASI was a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In the PASI system, the body was divided into 4 regions: head and neck, trunk (including axillae and groin), upper extremities, and lower extremities (included buttocks). Each of these areas was 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 to 100% involvement), and erythema, induration and scaling, each rated on a scale of 0 to 4, that was none to maximum severity. PASI produces a numeric score range from 0 (no psoriasis) to 72 (worst condition). Higher scores indicated more severe disease.

Time frame: Week 24

Percentage of Participants Who Achieved PASI 100 Response at Week 24 Among the Participants With >=3% BSA Psoriatic Involvement and an IGA Score of >=2 (Mild) at Baseline

PASI 100 response was defined as 100% reduction in PASI relative to baseline. PASI was a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In the PASI system, the body was divided into 4 regions: head and neck, trunk (including axillae and groin), upper extremities, and lower extremities (included buttocks). Each of these areas was 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 to 100% involvement), and erythema, induration and scaling, each rated on a scale of 0 to 4, that was none to maximum severity. PASI produces a numeric score range from 0 (no psoriasis) to 72 (worst condition). Higher scores indicated more severe disease.

Time frame: Week 24

Percentage of Participants With an IGA-psoriasis Response at Week 24 Among Participants With >=3% BSA Psoriatic Involvement and an IGA Score of >=2 (Mild) at Baseline

IGA psoriasis response was defined as an IGA psoriasis 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 participant's psoriasis at a given time point. Overall lesions were graded for induration, erythema, and scaling each using a 5 point scale: clear (0), minimal (1), mild (2), moderate (3), and severe (4). 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: Week 24

Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) at Week 24

Change from baseline in HAQ-DI score was a measure of the change in the physical function. It consists of a 20-questions instrument that assesses the degree of difficulty a person had 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 = no difficulty to 3= inability to perform a task. Scores on each task were summed and averaged to provide an overall HAQ-DI total score ranging from 0 (least difficulty) to 3 (extreme difficulty). Lower scores indicated better functioning. Negative change from baseline indicated improvement of physical function.

Time frame: Baseline (Week 0), Week 24

Percentage of Participants Who Had Resolution of Enthesitis at Week 24 Among the Participants With Enthesitis at Baseline

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

Time frame: Week 24

Percentage of Participants Who Achieved Resolution of Dactylitis Response at Week 24 Among the Participants With Dactylitis at Baseline

Dactylitis was characterized by swelling in both hands and feet. The severity of dactylitis was scored on a scale from 0 to 3 (0-no dactylitis, 1-mild dactylitis, 2-moderate dactylitis, and 3-severe dactylitis) for each digit. The results for each digit summed to produce final dactylitis score which was from 0 to 60. Higher score indicates more severe dactylitis. Dactylitis count was derived based on dactylitis score, each score was recorded to 0 or 1 from 0 to 3, where any score \>0 was recorded as 1. For resolution of dactylitis, it was defined as participants who had a dactylitis score greater than 0 at baseline and a score of 0 at the analysis visit.

Time frame: Week 24

Change From Baseline in Short Form Health Survey (SF-36) Physical Component Score (PCS) at Week 24

SF-36 was a multi-domain instrument with 36 items to evaluate 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). The scores for the 8 domains were combined into two summary scores: the physical component summary (PCS) score and the mental component summary (MCS) score. Domains 1 to 4 primarily contribute to the PCS score of the SF-36. Domains 5-8 primarily contributes to the MCS score of the SF-36. Each of the 8 domain scores and the component summary score ranged from 0=worst to 100=best. Higher scores represent better health status. A positive change indicates improvement while a negative change indicates worsening of health status and quality of life.
