FBS0701 is a once-daily oral capsule in development for the treatment of iron overload due to chronic blood transfusions in adults and children. FBS0701 has received Orphan Product designation from both the U.S. Food and Drug Administration and the European Medicines Agency. FerroKin BioSciences has completed four Phase 1 clinical trials to evaluate the safety, tolerability, pharmacokinetics and iron clearing activity of FBS0701 in healthy volunteers and patients. Phase 2 dose-ranging studies in adults and children are ongoing. Initial data from the adult study, presented at the American Society of Hematology in December, supports the potential for FBS0701 as an effective iron chelator with a favorable safety profile.About Iron Overload Although iron is an element essential for life - the typical adult human contains 1,000-4,000 mg of iron - the body has no means to eliminate excess iron. Repeated transfusions can result in the accumulation of iron in key organs, compromising their normal function. Progressive iron overload can eventually lead to organ failure, particularly the heart and liver. The need for repeated transfusions arises in the setting of both hereditary and acquired anemias. The most common forms of congenital anemia are the hemoglobinopathies, a group of related anemias including alpha and beta thalassemia and sickle cell disease affecting hemoglobin production. Acquired anemias tend to occur later in life and represent a diverse collection of conditions characterized by impaired blood cell production collectively called Myelodysplastic Syndrome (MDS).
