Efficacy and Safety of Ferriprox® in Patients With Sickle Cell Disease or Other Anemias — FIRST  

Sickle Cell Disease Clinical Trial

Official title: The Efficacy and Safety of Ferriprox® for the Treatment of Transfusional Iron Overload in Patients With Sickle Cell Disease or Other Anemias

Status Terminated

Clinical Trial Summary

This research is being done so that we can look at the safety and efficacy of deferiprone in people with sickle cell disease or other anemias. Deferiprone is a drug that removes iron from the body. We will be comparing deferiprone with deferoxamine, another drug that removes iron from the body.

Clinical Trial Description

Deferiprone (brand name Ferriprox®) is an iron chelator that is approved in the United States and over 60 other countries for the treatment of iron overload in patients with thalassemia, when other treatments are inadequate. This study has been designed to evaluate the efficacy, safety, and tolerability of deferiprone vs. deferoxamine in patients who have SCD or other anemias, and who require chelation because of the extra iron they are taking in through blood transfusions. About 300 people from North America, South America, Europe, and the Middle East will take part in this study. Participants will be randomized in a 2:1 ratio to receive therapy for 52 weeks with either deferiprone or deferoxamine, another type of iron chelator. Patients who are randomized to the deferiprone group can choose to get the drug as either tablets or liquid, and must take it three times daily. Patients who are randomized to the deferoxamine group will receive it as a subcutaneous infusion that lasts from 8 to 12 hours and is given 5 to 7 days per week. For both drugs, the starting dosage is based on how much extra iron they have taken in through transfusions in the last 3 months and on the severity of iron load, as measured by serum ferritin levels in the blood and by the amount of iron in the liver and the heart. For deferiprone, the starting dosage will be increased each week over the first 3 weeks; and for both drugs, the dosage may be adjusted up or down during the study based on the level of iron overload and on safety considerations. Patients will need to have their blood count checked every week for the first 26 weeks, then every other week for the remaining 26 weeks; they will also have to give a blood sample for more detailed safety testing every month; and to give a blood sample for the measurement of serum ferritin every 3 months. Every six months, they will undergo an ECG and an MRI scan, and will be asked to complete a quality of life survey. At the end of the 52 weeks, participants will be invited to enter a 2-year study in which all patients will receive deferiprone, including those who were randomized to receive deferoxamine in the first year. ;
