id="_Midostaurin_OVERVIEW_">OVERVIEW</h2><div id="Midostaurin.Introduction"><h3>Introduction</h3><p>Midostaurin is an orally available small molecule inhibitor of FMS-like tyrosine kinase 3 (FLT3) which is used as an antineoplastic agent in the treatment of acute myeloid leukemia with FLT3 mutations. Midostaurin is associated with a moderate rate of serum aminotransferase elevations during therapy and is suspected to cause rare instances of clinically apparent acute liver injury.</p></div><div id="Midostaurin.Background"><h3>Background</h3><p>Midostaurin (mye" doe staw' rin) is a potent small molecule multi-kinase inhibitor with specific activity against FLT3 (FMS-like tyrosine kinase 3), a tyrosine kinase receptor that is mutated in to up one-third of patients with acute myeloid leukemia (AML). The mutated FLT3 activates an intracellular signaling cascade of RAS-MEK-PI3K-AKT-STAT-5, promoting unregulated cell growth and proliferation. Midostaurin also has activity against other kinases including Kit, platelet derived growth factor receptor, vascular endothelial growth factor receptor 2 and members of the protein kinase C family. Midostaurin has been found to induce objective responses in a proportion of patients with refractory AML with detectable FLT3 mutations and in patients with advanced systemic mastocytosis. Midostaurin received accelerated approval for these indication in the United States in 2017 and is available in tablets of 25 mg under the brand name Rydapt. For newly diagnosed AML with FLT3 mutations, the recommended dose is 50 mg orally twice daily in combination with standard cytarabine and daunorubicin induction and cytarabine consolidation. For advanced systemic mastocytosis, the recommended dose is 100 mg orally twice daily, continued until progressive disease or intolerable toxicity occurs. Side effects are common and can include fatigue, myalgia, arthralgia, fever, cytopenias, diarrhea, nausea, abdominal pain, dizziness, headache, hypotension, cough and stomatitis. Potentially severe side effects include febrile neutropenia and sepsis, interstitial lung disease and embryo-fetal toxicity.</p></div><div id="Midostaurin.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>Elevations in serum aminotransferase levels are common during midostaurin therapy occurring in up to 71% of patients with AML also receiving standard induction therapy and rising above 5 times the upper limit of the normal range in 20%. In patients with systemic mastocytosis receiving midostaurin monotherapy, ALT elevations arose in 31% of patients and rose to above 5 times ULN in 4%. Hyperbilirubinemia was also common in these studies but instances of clinically apparent liver injury with jaundice, severe hepatoxicity and deaths from hepatic failure were not reported. However, because of the limited clinical experience with the use of midostaurin and other FLT3 inhibitors, their potential for causing liver injury is not well defined.</p><p>Likelihood score: E* (unproven but suspected cause of clinically apparent liver injury).</p></div><div id="Midostaurin.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The possible cause of the liver injury due to midostaurin is not known. Midostaurin is metabolized in the liver largely by the cytochrome P450 system (largely CYP 3A4) and is susceptible to drug-drug interactions with inhibitors or inducers of the microsomal enzyme system, and strong modulators of CYP 3A4 should be avoided in patients receiving midostaurin.</p></div><div id="Midostaurin.Outcome_and_Management"><h3>Outcome and Management</h3><p>Midostaurin therapy has been associated with transient serum aminotransferase elevations during therapy but has not been linked to instances of acute liver injury with jaundice or symptoms. Serum aminotransferase elevations above 5 times the upper limit of normal (if confirmed) should lead to temporary discontinuation, which should be permanent if laboratory values do not improve significantly or resolve within a few weeks or if symptoms or jaundice arise.</p><p>Drug Class: <a href="/books/n/livertox/AntineoplasticAgents/?report=reader">Antineoplastic Agents</a>, <a href="/books/n/livertox/ProteinKinaseInhibit/?report=reader">Protein Kinase Inhibitors</a></p></div></div><div id="Midostaurin.PRODUCT_INFORMATION"><h2 id="_Midostaurin_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><div id="Midostaurin.BPI" class="box boxed-text-box whole_rhythm hide-overflow"><p>
