Study on the Risk of Allergy-like Reactions After Intra-arterial or Intra-venous Injection of the Marketed X-ray Contrast Medium Iopromid
Germany133,331 participantsStarted 2018-10-12
Plain-language summary
Iopromide (trade name is Ultravist) is on the market for more than 30 years and has been used more than 250 million times as X-ray contrast medium for patients. It is known that Iopromide may cause allergy-like reactions after being injected. With this study researchers want to find out, if the risk of severe allergy-like reactions is lower, when Iopromide will be injected into an artery, compared to the risk after an injection of Iopromid into a vein. To find this out data from four trials on Iopromide that are already completed will be combined and newly analyzed. The database used for this analysis will contain data from more than 150,000 patients.

The study population consists of patients who received a contrast enhanced x-ray examination with Iopromide for various clinical reasons. Iopromide was administered either intra-venously or intra-arterially.
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.
