About this study

Official title: A Phase 3b, Multicenter, Randomized, Double-blind, Placebo-controlled Study Evaluating the Efficacy and Safety of Subcutaneously Administered Guselkumab in Improving the Signs and Symptoms and Inhibiting Radiographic Progression in Participants With Active Psoriatic Arthritis

The 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.

Being tested
Guselkumab, Placebo
Medical subject headings
Arthritis, Psoriatic

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • GuselkumabDrug

    Also called CNTO 1959

    Participants will receive guselkumab as SC injection.

  • PlaceboDrug

    Participants will receive matching placebo as SC injection.

Study groups in NCT04882098
Study groupRoleWhat they receive
Group 1: Guselkumab and PlaceboExperimentalParticipants will receive guselkumab and placebo subcutaneously (SC) to maintain the blind. Participants who have not discontinued will be eligible to enter a long-term extension (LTE) and will receive guselkumab and placebo SC. After the study is unblinded to the investigative sites, participants will receive guselkumab and no longer be required to dose with placebo to maintain the blind.
Receives: Drug: Guselkumab; Drug: Placebo
Group 2: GuselkumabExperimentalParticipants will receive guselkumab SC. Participants who have not discontinued will be eligible to enter an LTE and will receive guselkumab SC.
Receives: Drug: Guselkumab
Group 3: Placebo Followed by GuselkumabExperimentalParticipants will receive placebo SC and will cross over to receive SC guselkumab. Participants who have not discontinued will be eligible to enter an LTE and will receive guselkumab SC.
Receives: Drug: Guselkumab; Drug: Placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants Who Achieved an American College of Rheumatology (ACR) 20 Response at Week 24

    ACR 20 response: >=20% improvement from baseline (bl) in both swollen (66 joints), tender (68 joints) joint count, >=20% improvement from bl in 3 of 5 assessments: patient's assessment of pain using visual analog scale (VAS; 0-100mm, 0=no pain, 100=worst possible pain), patient's global assessment of disease activity (arthritis, VAS; 0-100mm, 0=excellent, 100=poor), physician's global assessment of disease activity (VAS; 0-100mm, 0=no arthritis activity,100=extremely active arthritis), HAQ-DI (questionnaire assessing 8 functional areas; 0-3, 0=no difficulty, 3=inability to perform task in area), and CRP. Natural Disaster (ND)-site inaccessible due to COVID-19. Major Disruption (MD)-disruption involving Ukraine and neighboring countries/territories. Intercurrent event (ICE) handling: Composite-discontinue study drug not due to ND/MD, initiate/increase DMARD/oral corticosteroid, initiate prohibited PsA treatment; Hypothetical-discontinue/severe noncompliance of study drug due to ND/MD.

    Measured: At Week 24

Secondary outcomes (11)
  1. Change From Baseline in Psoriatic Arthritis (PsA) Modified Van Der Heijde-Sharp (vdH-S) Total Score at Week 24

    Modified vdH-S score was sum of erosion score (hand, feet) and joint space narrowing (JSN) score (hand, feet). Joint erosion score was total erosion severity in 40 joints of 2 hands and 12 joints of 2 feet, maximum erosion score=320. Each hand joint was scored on 0 to 5 with 0 =no erosion, 5 =complete collapse of bone. Foot joint was scored on 0 to 10, 0 =no erosion, 10 =complete collapse of bone. JSN score was total JSN score in same 52 joints, each joint scored on 0 to 4 with 0 indicating no JSN, and 4 indicating absence of joint space, maximum JSN score=208. Maximum modified vdH-S score=528. Higher score =severe structural destruction and complete loss of joint spaces. Natural Disaster (ND)-site inaccessible due to COVID-19. Major Disruption (MD)-disruption involving Ukraine and neighboring countries/territories. Intercurrent event (ICE) handling: Hypothetical-discontinue/severe noncompliance of study drug due to ND/MD

    Measured: Baseline (after first administration of study drug) and Week 24

  2. Number of Participants With Treatment Emergent Adverse Events (TEAEs)

    Measured: From baseline (after first administration of study drug) up to 168 weeks

  3. Number of Participants With Serious Adverse Events (SAEs)

    Measured: From baseline (after first administration of study drug) up to 168 weeks

  4. Number of Participants With Reasonably Related Adverse Events (AEs)

    Measured: From baseline (after first administration of study drug) up to 168 weeks

  5. Number of Participants With TEAEs Leading to Discontinuation of Study Intervention

    Measured: From baseline (after first administration of study drug) up to 168 weeks

  6. Number of Participants With Treatment Emergent Infections

    Measured: From baseline (after first administration of study drug) up to 168 weeks

  7. Number of Participants With Injection-site Reactions Leading to Discontinuation of Study Intervention

    Measured: From baseline (after first administration of study drug) up to 168 weeks

  8. Number of Participants With Clinical Laboratory Abnormalities

    Measured: From baseline (after first administration of study drug) up to 168 weeks

  9. Number of Participants With Maximum Common Terminology Criteria for Adverse Events (CTCAE) Toxicity Grade Laboratory Values

    Measured: From baseline (after first administration of study drug) up to 168 weeks

  10. Serum Guselkumab Concentration

    Measured: From baseline (after first administration of study drug) up to 168 weeks

  11. Number of Participants With Anti-guselkumab Antibodies

    Measured: From baseline (after first administration of study drug) up to 168 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Guselkumab in people with Arthritis, Psoriatic, run by Janssen Research & Development, LLC at 280 sites in 29 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 4 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 280 sites in China, United States, Russia, Ukraine, Poland and 24 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Feb 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants Who Achieved an American College of Rheumatology (ACR) 20 Response at Week 24 (time frame: At Week 24). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04882098, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2026.
