Investigating Clinical Heterogeneity in Immune Checkpoint Inhibitor-induced Inflammatory Arthritis
United States1,000 participantsStarted 2026-07-01
Plain-language summary
Immune checkpoint inhibitors (ICI) can cause immune related adverse events like inflammatory arthritis (ICI-IA). ICI-IA is a new and impactful condition, but there is limited understanding of pathogenesis, natural history, and response to treatments. The study will have two main goals. 1. Evaluate efficacy of steroid sparing immunosuppression and determinants of ICI-IA persistence. 2. Identify biomarkers that predict ICI-IA disease severity and initial treatment-associated response.
These questions will be answered using the RADIOS cohort, a prospective cohort of patients with rheumatic immune related adverse events due to ICI therapy.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Disease activity as assessed by the Clinical Disease Activity Index (CDAI)
Timeframe: baseline, at 2-4 month follow up visit, at 3 months and 6 months post ICI cessation
