id="_Azacitidine_OVERVIEW_">OVERVIEW</h2><div id="Azacitidine.Introduction"><h3>Introduction</h3><p>Azacitidine is a cytosine analogue and antineoplastic agent used in the therapy of myelodysplastic syndromes. Azacitidine is associated with a low rate of transient serum enzyme elevations during therapy and has not been convincingly implicated in cases of clinically apparent acute liver injury with jaundice.</p></div><div id="Azacitidine.Background"><h3>Background</h3><p>Azacitidine (ay" za sye' ti deen: also spelled azacytidine) is a pyrimidine analogue (5-azacytidine) which is converted intracellularly to a triphosphate which becomes incorporated into RNA and DNA. While azacitidine has anticancer effects, it proved to have limited usefulness in solid tumors and lymphomas. In low doses, azacitidine inhibits methylation of DNA and results in the expression of silenced genes, including tumor suppressor genes. Studies done in vitro and in vivo have shown that azacitidine induces differentiation of bone marrow cells and results in normalization of bone marrow in a proportion of patients with myelodysplasia. Azacitidine was approved for use in the United States in 2004 and the current single indication is for therapy of myelodysplastic syndromes. It is also under evaluation as therapy of acute myelogenous leukemia. Azacitidine is available as a powder for injection in 100 mg vials under the trade name of Vidaza. The usual initial dosage regimen in adults is 75 mg/m<sup>2</sup> body surface area subcutaneously or intravenously each day for 7 days, with repeat courses after 28 days. A minimum of 4 courses is recommended and the dose can be increased to 100 mg/m<sup>2</sup> based upon tolerance and response. An oral form of azacitidine was approved in 2021 as maintenance therapy in patients with acute myelogenous leukemia after a first remission. Oral azacitidine is available in tablets of 200 and 300 mg under the brand name Onureg, the recommended dose being 300 mg on days 1 to 14 in 28-day cycles. Common side effects include bone marrow suppression, nausea, vomiting, diarrhea, stomatitis, bruising, abdominal pain, myalgias, headache, dizziness, fatigue, fever, rash and pruritus. Uncommon but potentially severe adverse events include severe myelosuppression, febrile neutropenia, pneumonitis, sepsis, tumor-lysis syndrome, and embryo-fetal toxicity.</p></div><div id="Azacitidine.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>In clinical trials, serum enzyme elevations occurred in up to 16% of patients on azacitidine therapy for cancer or myelodysplasia who had concurrent, underlying liver disease or liver metastases, but rarely in persons without a preexisting hepatic illness. In subsequent studies, liver adverse reactions attributed to azacitidine have rarely been reported, at least when it is given in conventional doses. Nevertheless, monitoring of serum enzyme levels is recommended in treating patients who have concurrent liver disease. Cases of clinically apparent liver injury attributed to azacitidine in patients without underlying liver disease have not been reported in the literature.</p><p>Likelihood score: E* (unproven but suspected cause of clinically apparent liver injury, particularly in persons with pre-existing liver disease).</p></div><div id="Azacitidine.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>Hepatotoxicity from azacitidine appears to be rare and confined mostly to patients with underlying liver disease. For these reasons, the liver injury is likely due to direct toxicity.</p></div><div id="Azacitidine.Outcome_and_Management"><h3>Outcome and Management</h3><p>The severity of the liver injury linked to azacitidine therapy is usually mild-to-moderate in severity occurring in patients with preexisting liver disease. Azacitidine has not been linked to cases of acute liver failure, chronic hepatitis or vanishing bile duct syndrome. There is no information on cross sensitivity to hepatic injury between azacitidine and other nucleoside or cytidine analogues.</p><p>Drug Class: <a href="/books/n/livertox/AntineoplasticAgents/?report=reader">Antineoplastic Agents</a></p><p>Other drugs for myelodysplastic syndromes: <a href="/books/n/livertox/Decitabine/?report=reader">Decitabine</a>, <a href="/books/n/livertox/Cedazuridine/?report=reader">Decitabine/Cedazuridine</a>, <a href="/books/n/livertox/Luspatercept/?report=reader">Luspatercept</a></p></div></div><div id="Azacitidine.PRODUCT_INFORMATION"><h2 id="_Azacitidine_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
