id="_ErythropoiesisStimul_OVERVIEW_">OVERVIEW</h2><div id="ErythropoiesisStimul.Introduction"><h3>Introduction</h3><p>Epoetin is a recombinant form of erythropoietin, a hematologic growth factor that induces proliferation and maturation of red blood cells and is used in the treatment of anemia caused by renal disease, myelodysplasia, cancer chemotherapy and hematopoietic cell transplantation. Epoetin and its various derivatives have not been associated with serum enzyme elevations during therapy or with instances of clinically apparent liver injury.</p></div><div id="ErythropoiesisStimul.Background"><h3>Background</h3><p>Epoetin (e poe' e tin) is a recombinant form of erythropoietin, a 165 amino acid glycoprotein that induces red blood cell production from their progenitors in the bone marrow. Erythropoietin is normally made in the kidneys and acts on progenitor erythroblasts through the erythropoietin receptor to cause proliferation and maturation of red cells. The major stimulus to erythropoietin synthesis is tissue hypoxia, but other factors can modulate the response. Deficiency of erythropoietin synthesis is common in end stage renal disease and may also be present in premature infants and in patients with malignancies, chronic inflammation and cancer chemotherapy. Recombinant forms of erythropoietin became available in the 1980&#x02019;s and were shown to raise hemoglobin and hematocrit levels in patients with end stage renal disease on hemodialysis, as well as in patients receiving cancer chemotherapy and patients with AIDS on drugs that cause anemia. Epoetin alfa was approved for use to treat anemia in patients with renal disease and receiving cancer chemotherapy in 1989 and is now widely used. Indications have broadened to include reduction of allogeneic red cell transfusion in patients undergoing elective surgery and it is used off-label for other forms of anemia associated with relative erythropoietin deficiency. The target hemoglobin level is usually between 11 and 12 g/dL. Epoetin alfa is available as a liquid solution for subcutaneous administration in vials and prefilled syringes under the brands name Epogen and Procrit, the dose and regimen varying by indication and initial response, being given by subcutaneous or intravenous injection at intervals varying from daily, several times weekly, weekly or as needed to achieve a target hemoglobin. Longer acting formulations are also available including darbepoetin (Aranesp: 2001) and peginesatide (Omontys, 2012, now withdrawn). Darbepoetin alfa (dar&#x0201d; be poe&#x02019; e tin) is a modified (hyperglycosylated) recombinant erythropoietin that has an extended half-life and can be administered every one to three weeks. Darbepoetin is available in single dose vials and prefilled syringes of varying concentrations and is administered intravenously or subcutaneously. Peginesatide (peg&#x0201d; in es&#x02019; a tide) is a novel synthetic pegylated dipeptide that mimics the effects of erythropoietin on red cell progenitors, despite having no amino acid homology to the native growth factor. Peginesatide was typically given either subcutaneously or intravenously at 4 week intervals, but was withdrawn from the market in 2013 because of reports of severe hypersensitivity reactions. Epoetin, darbepoetin and peginesatide are collectively referred to as erythropoiesis-stimulating agents (ESA). Dosages and dose regimens (daily, three times weekly, weekly, and every two to four weeks) vary by formulation, indications and initial response. Common side effects include hypertension (particularly in patients with renal disease), muscle and joint aches, fever, dizziness, headache, depression, cough and injection site reactions. Potentially serious, but rare side effects include hypersensitivity reactions, vascular occlusions, stroke and myocardial infarction.</p></div><div id="ErythropoiesisStimul.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>Epoetin and the erythropoiesis-stimulating agents have not been linked to instances of significant serum enzyme elevations or clinically apparent liver injury. In multiple large prelicensure studies, acute liver injury was not mentioned as an adverse event and serum enzyme tests changed minimally, if at all. Since licensure and wide scale use, there have been no published reports of liver injury from epoetin or its long acting forms. Interestingly, instances of induction of attacks of acute porphyria have been reported after epoetin use, probably because of induction hemoglobin production which requires an increase in porphyrin synthesis.</p><p>Likelihood score (all ESAs): E (unlikely cause of clinically apparent liver injury).</p></div><div id="ErythropoiesisStimul.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>A mechanism of injury that might lead to serum enzyme elevations during therapy with the ESAs is not known. Epoetin is a non-glycosylated form of erythropoietin and appears to be metabolized at multiple sites, probably by the cells on which they act.</p></div><div id="ErythropoiesisStimul.Outcome_and_Managem"><h3>Outcome and Management</h3><p>Serum aminotransferase elevations above 5 times the upper limit of normal (if confirmed) during ESA therapy should lead to dose reduction or temporary cessation. Epoetin and its derivatives have not been implicated in cases of severe hepatitis, acute liver failure, chronic hepatitis or vanishing bile duct syndrome. There is no reason to suspect any degree of cross sensitivity in risk for hepatic injury among the various hematologic growth factors and other agents used to treat bone marrow insufficiency.</p><p>Drug Class: <a href="/books/n/livertox/HematologicGrowthFac/?report=reader">Hematologic Growth Factors</a></p><p>Other Erythropoiesis Stimulating Agents: <a href="/books/n/livertox/Daprodustat/?report=reader">Daprodustat</a></p></div></div><div id="ErythropoiesisStimul.PRODUCT_INFORMATION"><h2 id="_ErythropoiesisStimul_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
