About this study
Official title: Feasibility, Tolerability and Efficacy of Extracorporeal Iron Purification in Patients With Myelodysplastic Syndrome or Myelofibrosis Intolerant of or Contraindicated to Oral or Subcutaneous Chelation Treatment.
In transfusion-dependent myelodysplastic syndromes patients, regular blood transfusions lead to iron overload, which can cause organ damage, hormonal imbalances, and increased infection risk, ultimately impacting patient survival. Standard oral iron chelation therapies can be intolerable for some patients due to adverse effects. The MEX-CD1 device (class III) could potentially offer an alternative for these patients by reducing serum iron levels through a novel, extracorporeal approach.
MEXIRON clinical investigation focuses on the use of MEX-CD1, a medical device designed for extracorporeal chelation therapy to reduce iron overload in patients suffering from transfusion-dependent myelodysplastic syndromes (MDS) and myelofibrosis.
Read more
MEXIRON aims to evaluate the device's use feasibility, safety, and effectiveness in reducing iron levels. Transfusions needs, patient experience and quality of life are also assessed.
Each enrolled patients will undergo three low-volume continuous veno-venous haemodialysis cycles within one week.
Following the three- haemodialysis cycles, patients will be monitored through on-site follow-up visits at 7 days, 28 days, and 90 days post-treatment to assess long-term effects.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Low-volume continuous veno-venous haemodialysis with MEX-CD1 useDevice
MEX-CD1 is a hyper-chelating colloidal solution that can be added to the dialysate to be used in low-volume continuous veno-venous hemodialysis. Intervention includes 3 low-volume continuous veno-venous hemodialysis for a duration of 3h20 each. For non-hospitalized patients, the treatment is performed on an outpatient basis.
