Plain English summary of protocol
Background and study aims
Active psoriatic arthritis (PsA) is a chronic disease that causes joint pain and swelling. Patients may also have red patches on their skin. Psoriatic arthritis can affect any joint in the body, including fingers, toes, knees, and the spine. This can make it harder to move around and do everyday tasks. Drugs that prevent interleukin IL-23 (a specific type of protein involved in inflammation) from binding to its receptor (a protein that binds to specific molecules) may be an effective way to disease control. The study drug, icotrokinra, is a medicine designed to target the IL-23 receptor and block IL-23 from binding to it. In this study, researchers want to check how well icotrokinra works when compared to placebo (does not contain any active medication) in participants with PsA.
Who can participate?
Participants aged 18 years or older with PsA can participate.
What does the study involve?
This study lasts for 52 weeks, with an additional 52-week extension. At the start, participants will be randomly assigned to one of three groups: Group I will receive Dose 1 of icotrokinra daily, Group II will receive Dose 2 daily, and Group III will receive a placebo daily. At Week 16, participants will switch to either Dose 1 or Dose 2 of icotrokinra. The study includes a screening period of up to 5 weeks, a placebo-controlled period of up to 16 weeks, a blinded active-treatment period of up to 36 weeks, and a safety follow-up visit 4 weeks after the last dose. Participants who complete the main study can join the 52-week extension, which includes 48 weeks of active treatment and 4 weeks of safety follow-up. Safety assessments will monitor adverse events, vital signs, questionnaires, and blood tests, with all side effects recorded until the study ends, approximately 2 years in total.
What are the possible benefits and risks of participating?
There is no established benefit to participants of this study. Based on scientific theory, taking icotrokinra may improve active psoriatic arthritis. However, this cannot be guaranteed because icotrokinra is still under investigation as a treatment, and it is not known whether active psoriatic arthritis will work. In addition, if participants are put into the placebo treatment group, they will not receive icotrokinra. At Week 16, participants assigned to the placebo group will cross over to receive icotrokinra Dose 1 or Dose 2 once daily.
Participants may experience some benefit from participation in the study that is not due to receiving study drug, but due to regular visits and assessments monitoring overall health. Participation may help other people with psoriatic arthritis (PsA) in the future.
Participants may have side effects from the drugs or procedures used in this study that may be mild to severe and even life-threatening, and they can vary from person to person. Participants may have side effects from the drugs or procedures used in this study that may be mild to severe and even life-threatening, and they can vary from person to person. Some potential risks included hypersensitivity reactions (inappropriate or exaggerated response to an antigen or an allergen), anti-drug antibody production, and infection. The participant information sheet and informed consent study drug or placebo form, which will be signed by every participant agreeing to participate in the study, includes a detailed section outlining the known risks of participating in the study.
Not all possible side effects and risks related to icotrokinra are known at this moment. During the study, the sponsor may learn new information about icotrokinra. The study doctor will tell participants as soon as possible about any new information that might make them change their minds about being in the study, such as new risks.
To minimise the risk associated with taking part in the study, participants are frequently reviewed for any side effects and other medical events. Participants are educated to report any such events to their study doctor who will provide appropriate medical care. Any serious side effects that are reported to the sponsor are thoroughly reviewed by a specialist drug safety team.
There are no costs to participants to be in the study. The sponsor will pay for the study drug and tests that are part of the study. The participant will receive reasonable reimbursement for study-related costs (e.g., travel/parking costs).

| Scientific title | A Phase III, multicenter, randomized, double-blind, placebo-controlled study evaluating the efficacy and safety of JNJ-77242113 for the treatment of biologic-experienced participants with active psoriatic arthritis |
| Study acronym | ICONIC-PsA 2 |
| Study objectives | Primary objective: To evaluate how well icotrokinra (JNJ-77242113) works at Dose 1 and Dose 2 doses compared to a placebo in reducing psoriatic arthritis (PsA) symptoms at Week 16. Secondary objectives: To evaluate the following for icotrokinra compared to a placebo in participants with PsA at Week 16: 1. Efficacy in improving skin symptoms, like rashes or patches. 2. Efficacy in reducing joint pain, swelling, and other symptoms of PsA. 3. Efficacy in improving physical function, such as movement and daily activities. 4. Efficacy in improving health-related quality of life (HRQoL). 5. Efficacy in reducing enthesitis (inflammation where tendons or ligaments attach to bone) and dactylitis (swelling of fingers or toes). 6. To further evaluate how well icotrokinra works compared to a placebo in people with PsA. 7. Efficacy in reducing fatigue symptoms. |
