This clinical trial is focused on studying the effects of a new treatment for Psoriatic Arthritis, a condition that causes joint pain and swelling in people who have psoriasis. The study will evaluate a medication known as JNJ-77242113, which is taken as a tablet. Participants in the study will be those who have not previously been treated with biologic medications, which are a type of advanced treatment for autoimmune diseases like psoriatic arthritis.
The purpose of the study is to assess how effective and safe JNJ-77242113 is in reducing the signs and symptoms of psoriatic arthritis. The study will compare the effects of this medication to a placebo, which is a substance with no active drug. Participants will receive either the medication or the placebo and will be monitored over a period of time to see how their symptoms change.
During the study, participants will receive the treatment for up to 100 weeks. The medication will be administered in different doses, and the effects will be evaluated at various points, including at 16 weeks. The study aims to provide valuable information on whether JNJ-77242113 can be a beneficial treatment option for those suffering from active psoriatic arthritis.
