Ferrous Acetyl-Aspartate Casein Formulation Evaluation Over Ferrous Sulfate in Iron Deficiency Anemia — ACCESS  

Iron Deficiency Anemia Clinical Trial

Official title: Ferrous Acetyl-Aspartate Casein Formulation Evaluation Over Ferrous Sulfate in Iron Deficiency Anemia (ACCESS): A Double-Dummy Randomized Clinical Trial

Status Completed

Clinical Trial Summary

The scope of this study is to compare the efficacy of the new oral formulation of Fe-ASP to oral ferrous sulfate in patients with iron deficiency anemia (IDA) for the restoration of decreased circulating Hb. The improvement of symptoms of anemia, the restoration of biomarkers of iron deficiency into the normal range and the incidence of GI tract side effects are the study secondary endpoints.

Clinical Trial Description

Anemia is a major problem in the general population affecting 5.6% in the United States. Iron deficiency is the most common cause of anemia. Although traditionally considered to be mainly a problem of underdeveloped countries, a recent epidemiological survey reported high incidence of iron deficiency anemia (IDA) in Europe in 2011. The incidence rate measured per 1,000 person-years was 8.18 in Belgium, 8.93 in Italy, 12.42 in Germany and 14.14 in Spain. Women were affected four-times more than men. The major causes of IDA are chronic blood loss, chronic disorders and excess needs. The cornerstones of management of IDA are recognition and management of the cause of iron loss and efficient iron supplementation. Iron supplementation is usually done through oral formulations of iron. Three oral iron preparations are broadly used: ferrous sulfate, ferrous gluconate, and ferrous fumarate. The usual dosage is 325 mg (corresponding to 65 mg of elemental iron) two times a day. One major limitation with oral iron supplementation is GI side effects observed in almost 40% of cases. These are gastric discomfort, nausea, vomiting and constipation and they are caused due to the oxidation of ferrous irons in the stomach by acidic gastric fluid into insoluble salts. A new formulation of iron conjugated to one N-acetyl-aspartate derivative of casein (Fe-ASP) has recently been developed. Due to the casein coating, it is anticipated that iron is converted to a smaller extent in the stomach into insoluble salts. In this way, more iron reaches the duodenum to become absorbed whereas GI side effects are less often. In parallel, animal studies have shown that casein itself primes the expression of enzymes that facilitate the absorption of iron across the duodenal mucosa. This formulation is anticipated to be better tolerated for oral ingestion since iron is readily absorbed in the duodenum. The aim is to compare the efficacy of the new oral formulation of Fe-ASP to oral ferrous sulfate in patients with IDA for the restoration of decreased circulating Hb. ;
