Hepcidin
Overview
Hepcidin is a 25-amino acid endogenous peptide hormone produced primarily by hepatocytes that serves as the master regulator of systemic iron homeostasis. It binds to ferroportin, the sole known cellular iron exporter, inducing its internalization and degradation, thereby blocking iron release from enterocytes, macrophages, and hepatocytes. Therapeutic hepcidin agonists and antagonists are being developed to treat iron overload disorders and anemia of chronic disease, respectively.
Key Research Findings
Hepcidin was first characterized in 2001 (Blood, JCI) as a key iron regulatory hormone. Multiple hepcidin mimetics and antagonists have entered Phase 1 and Phase 2 clinical trials for conditions including beta-thalassemia, polycythemia vera, and anemia of chronic kidney disease, though none have yet achieved regulatory approval.

Bivalirudin (Angiomax)
FDA ApprovedA synthetic 20-amino acid peptide that acts as a direct thrombin inhibitor by binding both the catalytic active site and anion-binding exosite 1 of thrombin. Bivalirudin inhibits both free and clot-bound thrombin, providing more predictable anticoagulation than heparin without requiring antithrombin III as a cofactor. It is enzymatically cleaved by thrombin itself, producing a self-limiting anticoagulant effect with a 25-minute half-life.
Romiplostim (Nplate)
FDA ApprovedA thrombopoietin (TPO) receptor agonist consisting of a peptide sequence that binds the TPO receptor (c-Mpl) fused to an IgG1 Fc domain (peptibody). Romiplostim activates JAK2/STAT5 signaling in megakaryocyte progenitors, promoting megakaryocyte proliferation, differentiation, and platelet production. It has no sequence homology to endogenous TPO, minimizing the risk of cross-reactive antibody formation.
Pegcetacoplan (Empaveli)
FDA ApprovedA pegylated cyclic peptide that inhibits complement component C3, the central node of all three complement activation pathways (classical, lectin, and alternative). By binding C3 and preventing its cleavage into C3a and C3b, pegcetacoplan blocks both intravascular hemolysis (mediated by membrane attack complex) and extravascular hemolysis (mediated by C3b opsonization and phagocytosis). This dual mechanism addresses the limitation of C5 inhibitors that only prevent intravascular hemolysis.
Peginesatide (Omontys)
FDA ApprovedPeginesatide is a synthetic pegylated peptide-based erythropoiesis-stimulating agent (ESA) consisting of two 21-amino acid chains linked to polyethylene glycol. Unlike recombinant erythropoietin, it contains no erythropoietin sequence homology yet activates the erythropoietin receptor to stimulate red blood cell production. The pegylation confers a prolonged half-life, enabling once-monthly dosing in dialysis-dependent chronic kidney disease.
