Interruption of TNFinhibitors and Endothelial Function

48 participantsStarted 2012-09

Plain-language summary

Patients with rheumatoid arthritis (RA) have an increased risk of cardiovascular events. This increased risk is thought to be driven by inflammation-induced endothelial dysfunction, an initial step in atherogenesis. Treatment with TNFalpha inhibitors (TNFi) improve endothelial function in patients with RA. Discontinuation of TNFi could therefore worsen endothelial function even in the absence of recurrence of systemic inflammation or reactivation of arthritis. If stopping TNFi results in worsening of endothelial function this would strongly suggest a higher cardiovascular risk in association with TNFi-wthdrawal

Inclusion Criteria: * Informed consent for POEET trial and this additional study * On stable medication (except for TNFi-therapy) Exclusion Criteria: * Uncontrolled hypertension (RR \> 140/90 mmHg average of three measurements at screening after 5 minutes of supine rest) * Diabetes mellitus * Heart failure or any other cardiovascular disease that is expected to induce changes in cardiovascular medication during the study period. * Expected to start or change medication that can alter endothelial function (lipid lowering drugs, blood pressure lowering drugs, NSAIDs, immunosuppressive therapy other than TNFi drugs)

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.
