Improving recovery after surgery with intravenous iron treatment

Official title: Improved Recovery by Iron Following Surgery With Blood Loss, a Double-blind Multi-centre Randomized Controlled Phase III Drug Trial (the IRIS-trial)

Run by Uppsala University Hospital · NCT05744219 · Data updated 2026-11-12

This study tests if giving intravenous iron to patients who lose a lot of blood during major surgeries can help them recover better and need fewer blood transfusions.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 years old, weighing more than 50 kg, who are scheduled for complex aortic surgery or liver/pancreatic resections.

Probably not a fit

Patients with severe anemia, contraindications to Ferric Carboxymaltose, or those with a short expected survival may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the effects of intravenous Ferric Carboxymaltose on recovery following major surgeries that involve significant blood loss, such as liver and aortic surgeries. Patients scheduled for these procedures will be screened for eligibility and, if they experience blood loss between 400-4000 ml during surgery, will be randomized to receive either the iron treatment or a placebo. The study aims to determine if this intervention can enhance post-operative recovery and reduce the need for red blood cell transfusions.

Why it matters

Potential benefit: If successful, this treatment could significantly improve recovery times and outcomes for patients undergoing major surgeries with blood loss.

How similar studies have gone: Other studies have shown promising results with intravenous iron treatments in similar surgical contexts, suggesting potential for success in this approach.
