Summary

This trial is testing a new drug for people with psoriatic arthritis to see if it can reduce symptoms.

Who is the study for?
This trial is for people with active psoriatic arthritis who've tried other treatments like DMARDs, apremilast, or NSAIDs without enough relief. They should have symptoms like swollen and tender joints, a certain level of inflammation in their blood, and joint damage visible on X-rays. It's not for those with other inflammatory diseases that could affect results or anyone allergic to the study drug.
What is being tested?
The trial tests Guselkumab's effectiveness against PsA by comparing it to a placebo. Participants will be randomly assigned to receive either Guselkumab or an inactive substance (placebo) to see if there's a significant improvement in their PsA symptoms.
What are the potential side effects?
Guselkumab may cause side effects such as infections, headaches, injection site reactions (like pain or swelling), and possibly allergic reactions. The exact side effects can vary from person to person.

Trial Design

3Treatment groups
Experimental Treatment
Group I: Group 3: Placebo Followed by GuselkumabExperimental Treatment2 Interventions
Participants 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.
Group II: Group 2: GuselkumabExperimental Treatment1 Intervention
Participants will receive guselkumab SC. Participants who have not discontinued will be eligible to enter an LTE and will receive guselkumab SC.
Group III: Group 1: Guselkumab and PlaceboExperimental Treatment2 Interventions
Participants 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.
