Arthritis, Psoriatic
Conditions
Brief summary
The purpose of this study is to evaluate how well the study drug JNJ-88545223 works compared with a placebo (an inactive substance) in adults with active psoriatic arthritis (PsA). The study aims to see whether treatment with JNJ-88545223 can help reduce the signs and symptoms of PsA and improve joint and skin health.
Interventions
JNJ-88545223 will be administered.
Placebo will be administered.

Inclusion criteria
* Have a diagnosis of psoriatic arthritis (PsA) for at least 3 months before the first administration of study intervention and meet classification criteria for Psoriatic Arthritis (CASPAR) at screening * Have active PsA as defined by: (a) At least 3 swollen joints and at least 3 tender joints at screening and at baseline (Week 0/Day 1) based on the 66/68 joint assessment; AND (b) C-reactive protein (CRP) greater than or equal to (\>=) 0.1 milligrams per deciliter (mg/dL) at screening from the central laboratory * Have \>= 1 of the following PsA subsets: distal interphalangeal joint involvement, polyarticular arthritis with absence of rheumatoid nodules, asymmetric peripheral arthritis, or spondylitis with peripheral arthritis * Have active plaque psoriasis with at least one psoriatic plaque of \>= 2 centimeter (cm) diameter or nail changes consistent with psoriasis * A female participant of childbearing potential must have a negative highly sensitive serum pregnancy test (Beta-hCG) at screening and a negative urine pregnancy test at Week 0 prior to administration of study intervention
Exclusion criteria
* Has a nonplaque form of psoriasis (for example, erythrodermic, guttate, or pustular) * Has a history or current signs or symptoms of severe, progressive, or uncontrolled renal, hepatic, cardiac, vascular, pulmonary, gastrointestinal, endocrine, neurologic, hematologic, rheumatologic (except PsA), psychiatric, genitourinary, or metabolic disturbances * Has suspected or known allergies, hypersensitivity, or intolerance to JNJ-88545223 or excipients used in the investigational medicinal product (IMP), including placebo (JNJ-88545223 investigator's brochure); or has a history of severe allergic reaction, angioedema, or anaphylaxis to drugs or food * Has fibromyalgia or osteoarthritis symptoms that, in the opinion of the investigator, would have potential to interfere with efficacy assessments * Currently has a malignancy or has a history of malignancy within 5 years prior to screening
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of Participants who Achieved an American College of Rheumatology (ACR) 50 Response at Week 16 | Week 16 | The ACR 50 responders are participants with an improvement of greater than or equal to (\>=) 50 percent (%) from baseline in both the tender and swollen joint count and in at least 3 of the 5 assessments (patient's assessment of pain visual analog scale \[VAS\], patient's global assessment of disease activity \[arthritis, VAS\] scale, Physician's global assessment of disease activity VAS scale, Health Assessment Questionnaire and C-reactive protein). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of Participants Who Achieved Psoriatic Area and Severity Index (PASI) 75 Response at Week 16 Among Participants with Baseline Body Surface Area (BSA) Greater Than or Equal to (>=) 3 Percent (%) | Week 16 | A PASI 75 response represents participants who achieved at least a 75 percent improvement from baseline in the PASI score. The PASI is a system used for assessing and grading the severity of psoriatic lesions. In the PASI system, the body is divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas were assessed separately for the percentage of the area involved, which translates to a numeric score that ranges from 0 to 6, and for erythema, induration, and scaling, which are each rated on a scale of 0 to 4. The PASI produces a numeric score that can range from 0 to 72. A higher score indicates more severe disease. |
| Proportion of Participants Who Achieved PASI 90 Response at Week 16 Among Participants with Baseline BSA >=3% | Week 16 | A PASI 90 response represents participants who achieved at least a 90 percent improvement from baseline in the PASI score. The PASI is a system used for assessing and grading the severity of psoriatic lesions. In the PASI system, the body is divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas were assessed separately for the percentage of the area involved, which translates to a numeric score that ranges from 0 to 6, and for erythema, induration, and scaling, which are each rated on a scale of 0 to 4. The PASI produces a numeric score that can range from 0 to 72. A higher score indicates more severe disease. |
| Proportion of Participants Who Achieved PASI 100 Response at Week 16 Among Participants with Baseline BSA >=3% | Week 16 | A PASI 100 response represents participants who achieved at least a 100 percent improvement from baseline in the PASI score. The PASI is a system used for assessing and grading the severity of psoriatic lesions. In the PASI system, the body is divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas were assessed separately for the percentage of the area involved, which translates to a numeric score that ranges from 0 to 6, and for erythema, induration, and scaling, which are each rated on a scale of 0 to 4. The PASI produces a numeric score that can range from 0 to 72. A higher score indicates more severe disease. |
| Proportion of Participants who Achieved an ACR 20 Response at Week 16 | Week 16 | The ACR 20 responders are participants with an improvement of \>= 20% from baseline in both the tender and swollen joint count and in at least 3 of the 5 assessments (patient's assessment of pain VAS, patient's global assessment of disease activity \[arthritis, VAS\] scale, Physician's global assessment of disease activity VAS scale, Health Assessment Questionnaire and C-reactive protein). |
| Proportion of Participants who Achieved an ACR 70 Response at Week 16 | Week 16 | The ACR 70 responders are participants with an improvement of \>= 70% from baseline in both the tender and swollen joint count and in at least 3 of the 5 assessments (patient's assessment of pain VAS, patient's global assessment of disease activity \[arthritis, VAS\] scale, Physician's global assessment of disease activity VAS scale, health assessment questionnaire and C-reactive protein). |
| Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) Score At Week 16 | Baseline up to Week 16 | The HAQ-DI score consists of questions referring to 8 categories: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and common daily activities. Responses in each functional area are scored from 0 to 3 (0=no difficulty and 3=inability to perform a task in that area). Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range 0-3 where 0 = least difficulty and 3 = extreme difficulty. |
| Change From Baseline in 36 Item Short Form Survey (SF-36) Physical Component Summary (PCS) Score at Week 16 | Baseline up to Week 16 | SF-36 is a standardized survey evaluating 8 aspects of functional health and wellbeing: physical and social functioning, physical and emotional role limitations, bodily pain, general health, vitality, mental health. The score for a domain was an average of the individual question scores, which were scaled 0 to 100 (100=highest level of functioning). Score from physical function, role physical, bodily pain, and general health domains were averaged to calculate PCS. Total score range for PCS was 0-100 (100=highest level of physical functioning). |
