A Trial Comparing Ferumoxytol to Iron Sucrose for the Treatment of Iron Deficiency Anemia in Adult Subjects With Chronic Kidney Disease

Ferumoxytol Compared to Iron Sucrose Trial (FIRST): A Randomized, Multicenter, Trial of Ferumoxytol Compared to Iron Sucrose for the Treatment of Iron Deficiency Anemia in Adult Subjects With Chronic Kidney Disease

The purpose of the study is to evaluate the safety and efficacy of intravenous (IV) ferumoxytol compared to IV iron sucrose for the treatment of iron deficiency anemia (IDA) in participants with chronic kidney disease (CKD).
