A Study of Guselkumab Administered Subcutaneously in Bio-naive Participants With Active Psoriatic Arthritis Axial Disease
- Registration Number
- NCT04929210
- Lead Sponsor
- Janssen Research & Development, LLC
- Brief Summary
The purpose of this study is to evaluate the efficacy of guselkumab treatment in participants with active psoriatic arthritis (PsA) axial disease by assessing reduction in axial symptoms and inflammation.
- Detailed Description
PsA is a chronic inflammatory musculoskeletal disease that has 6 disease domains, and axial disease represents one of the domains. Guselkumab is a fully human immunoglobulin (Ig) G1 lambda monoclonal antibody (mAb) that by binding to the p19 protein subunit of interleukin (IL)-23, blocks the binding of extracellular IL-23 to the cell surface IL-23 receptor, inhibiting IL-23-mediated intracellular signaling, activation, and cytokine production. This study will consist of a screening phase (up to 6 weeks), a treatment phase (up to 48 weeks, including a placebo-controlled period from Week 0 to Week 24 and an active-controlled treatment phase from Week 24 to Week 48), and a safety follow-up phase (up to Week 60). The efficacy assessments will include assessment such as Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score and the safety assessments will include evaluations of physical examinations, vital signs, electrocardiograms, clinical laboratory tests, and adverse events. The overall duration of the study will be up to 14 months.

- Primary Outcome Measures
Name Time Method Change from Baseline in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Score at Week 24 Baseline and Week 24 BASDAI is a self-assessment tool that consists of 6 questions relating to 5 major symptoms of ankylosing spondylitis: fatigue, spinal pain, joint pain, enthesitis, qualitative morning stiffness and quantitative morning stiffness. First 5 items were scored on a 10 centimeter (cm) visual analog scale (VAS) ranging from 0 equals to (=) none to 10=very severe. Quantitative morning stiffness was scored on a 10 cm VAS ranging from 0=0 hours to 10=2 or more hours. 2 scores for qualitative and quantitative morning stiffness were averaged, and total BASDAI score was average of the 5 scores of each symptom, ranging from 0 (none) to 10 (very severe). Higher scores indicate greater disease severity.
- Secondary Outcome Measures
Name Time Method Change from Baseline in Disease Activity Index for Psoriatic Arthritis (DAPSA) at Week 24 Baseline and Week 24 DAPSA assessed the joint domain of psoriatic arthritis (PsA) and was derived from the sum of the following components: tender joint count (0-68), swollen joint count (0-66), CRP level (milligram/deciliter \[mg/dL\], value less than \[\<\] lower limit of quantification \[LLOQ\] is considered equal to half of the value of LLOQ for numerical calculations), participant assessment of pain (0-10 cm VAS, 0=no pain, 10=worst possible pain), and participant's global assessment of disease activity on arthritis (0 to 10 cm 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.
Percentage of Participants with Investigator's Global Assessment (IGA) 0/1 Response at Week 24 among Participants with >= 3% Body Surface Area (BSA) Psoriatic Involvement and an IGA Score of >=2 (Mild) at Baseline Week 24 Percentage of participants with IGA 0/1 response at week 24 among the participants with \>= 3 percent (%) BSA psoriatic involvement and an IGA score of \>= 2 (mild) at baseline will be reported. The IGA documents the investigator's assessment of the participants psoriasis at a given timepoint. Overall lesions are graded for induration, erythema, and scaling using 0 (no evidence), 1 (minimal), 2 (mild), 3 (moderate) and 4 (severe) scale. The IGA score of psoriasis is based upon the average of induration, erythema and scaling scores. The participant's psoriasis is assessed as cleared (0), minimal (1), mild (2), moderate (3), or severe (4).
Change from Baseline in Health Assessment Questionnaire - Disability Index (HAQ-DI) Score at Week 24 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.
Percentage of Participants who Achieve ASDAS Major Improvement at Week 24 Week 24 Percentage of participants who achieve ASDAS major improvement at Week 24 will be reported.
Change from Baseline in SPARCC Score for MRI Spine at Week 24 Baseline and Week 24 Change from baseline in SPARCC score for MRI spine at week 24 among the participants with a positive MRI of the spine at baseline will be reported. The SPARCC scoring system for the spine scores the 6 discovertebral units considered by the reader as the most abnormal, and then separately assesses each quadrant of 3 adjacent sagittal slices, with additional points for "depth" and high "intensity" of the lesion.
Number of Participants with Serious Adverse Events (SAEs) Up to 60 weeks A SAE is any untoward medical occurrence that at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; is a suspected transmission of any infectious agent via a medicinal product; is medically important.
Number of Participants with Reasonably Related AEs Up to 60 weeks An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
Change from Baseline in Spondyloarthritis Research Consortium of Canada (SPARCC) Score for Magnetic Resonance Imaging (MRI) Sacroiliac (SI) Joints at Week 24 Baseline and Week 24 Change from baseline in SPARCC score for MRI SI joints at week 24 among the participants with a positive MRI of the sacroiliac joints at baseline will be reported. SPARCC method focuses on the cartilaginous portion of the SI joint, and scores presence (score of 1) versus absence (score of 0) of bone marrow edema in each SI joint quadrant.
Percentage of Participants who Achieve a >= 50 % Improvement from Baseline in BASDAI Score at Week 24 Baseline and Week 24 Percentage of participants who achieve a \>= 50 % improvement from baseline in BASDAI score at week 24 will be reported.

Change from Baseline in Ankylosing Spondylitis Disease Activity Score-C-Reactive Protein (ASDAS-CRP) at Week 24 Baseline and Week 24 The ASDAS-CRP is a composite of 5 disease activity variables with only partial overlap. The 4 self-reported items included in this index are back pain (VAS), duration of morning stiffness, peripheral pain/swelling, and participant global assessment of disease activity; these are combined with the C-reactive protein (CRP) value. Selected cut-offs for improvement scores are: a change greater than or equal to (\>=) 1.1 units for "clinically important improvement" and a change \>= 2.0 units for "major improvement.
Percentage of Participants who Achieve ASDAS Clinically Important Improvement at Week 24 Week 24 Percentage of participants who achieve ASDAS clinically important improvement at week 24 will be reported.
