Trastuzumab emtansine has been linked to frequent serum enzyme elevations during therapy, to occasional instance of acute clinically apparent liver injury and, when given chronically, to nodular regenerative hyperplasia and noncirrhotic portal hypertension.</p></div><div id="TrastuzumabEmtansine.Background"><h3>Background</h3><p>Trastuzumab (tras tooz’ ue mab) emtansine (em tan’ seen) is a humanized monoclonal antibody to the human epidermal growth factor receptor-2 (HER2) conjugated to emtansine (DM1), a cytotoxic microtubule inhibitor, which is used in the therapy of advanced or metastatic forms of breast cancer that express HER2. The monoclonal antibody is linked by a cleavable tetrapeptide to the microtubule inhibitor which is released intracellularly after the conjugate binds to and is taken up by HER2 expressing cancer cells. Within the cancer cell, emtansine is released by lysosomal enzymes that cleave the linker molecule. The released emtansine then binds to microtubules causing cell cycle arrest and apoptotic cell death. This conjugate was shown to induce objective responses and improve survival in patients with unresectable or metastatic breast cancer who had progressed despite previous therapies, and it was approved for this indication in the United States in 2013. The antibody conjugate is available in single use vials of 100 mg per vial or 160 mg lyophilized powder under the brand name Kadcyla. The recommended dose is 3.6 mg/kg intravenously every 3 weeks until disease progression or intolerability. The antibody conjugate has a higher rate of adverse side effects than trastuzumab alone. The common adverse events include fatigue, nausea, vomiting, diarrhea, fever, myalgias, headache, constipation, serum enzyme elevations and thrombocytopenia. Less common but potential severe adverse events include hepatotoxicity, anaphylaxis, heart failure and embryo-fetal toxicity. Trastuzumab emtansine should be prescribed and administered only by health care workers with expertise and experience in cancer chemotherapy and management of its adverse events.</p></div><div id="TrastuzumabEmtansine.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>In large registration trials of trastuzumab emtansine for breast and other cancers, serum enzyme elevations occurred in 20% to 80% of patients and levels rose to above 5 times the upper limit of normal (ULN) in at least 5%. Some aminotransferase elevations were accompanied by serum bilirubin elevations. Subsequent to its approval and more widespread use, instances of acute liver injury including deaths from hepatic failure were reported with trastuzumab emtansine treatment, and it received a boxed warning about hepatotoxicity with recommendations for prospective monitoring of liver tests. Some cases appeared to represent acute sinusoidal obstruction syndrome and in other cases acute, direct hepatotoxic injury.</p><p>More recently, cases of noncirrhotic portal hypertension have been described in patients on long term trastuzumab emtansine. The typical presentation is with signs and symptoms of portal hypertension after months or years of therapy and usually with only modest increases in serum aminotransferase elevations and bilirubin. Strikingly, in patients who undergo liver biopsy, cirrhosis is not present, although mild-to-moderate fibrosis is present in some. This phenotype of injury is classified as noncirrhotic portal hypertension, but the underlying liver condition is usually nodular regenerative hyperplasia with elements of sinusoidal obstruction. Hepatic imaging shows a nodular and somewhat shrunken liver and prominent splenomegaly and varices. Typically, patients improve clinically once trastuzumab emtansine is dose-reduced or discontinued, although without chemotherapy the malignancy may return and progress. Another syndrome with somewhat similar clinical features associated with long term trastuzumab emtansine therapy is a disordered, nodular liver cause by shrinkage of necrotic hepatic metastases, sometimes referred to as “pseudocirrhosis.” These patients generally do not have symptoms of liver disease, and the diagnosis is made by hepatic imaging often done as a part of routine follow up of the metastatic liver disease.</p><p>Likelihood score: B (likely cause of clinically apparent liver injury).</p></div><div id="TrastuzumabEmtansine.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The cause of the serum enzyme elevations during trastuzumab emtansine therapy is not known, but appears to be dose related and may be a mild direct toxicity of the infusions. The mechanism of the hepatotoxicity may be direct injury to endothelial cells and vasculature, possibly by their take up of the conjugate or the released microtubule inhibitor from other cells. Several instances of liver injury in patients taking trastuzumab emtansine have been attributed to sinusoidal obstruction syndrome, and mild forms of it may explain the frequent serum enzyme and bilirubin elevations during trastuzumab emtansine therapy. In other instances the underlying condition appears to be nodular regenerative hyperplasia, which is likely the result of acute or chronic vascular injury or both.</p></div><div id="TrastuzumabEmtansine.Outcome_and_Managem"><h3>Outcome and Management</h3><p>The product label for trastuzumab emtansine recommends monitoring of liver enzymes before starting and before each dose. The serum aminotransferase elevations that arise during trastuzumab emtansine therapy are usually mild-to-moderate in severity, self-limited in course, and not associated with symptoms or jaundice. In some instances, however, the injury persists or is more severe. Elevations of serum aminotransferase levels above 5 times ULN should lead to dose interruption or modification, but persistent elevations, appearance of symptoms or jaundice or evidence of sinusoidal obstruction syndrome should lead to discontinuation. Fatal instances of acute hepatic injury have been described with trastuzumab emtansine therapy. The chronic liver injury from the monoclonal-cytotoxic conjugate is generally persistent although signs and symptoms usually regress with drug discontinuation and sometimes with dose reduction alone. These clinically apparent and severe hepatic reactions have been observed with trastuzumab emtansine, but not with trastuzumab deruxtecan or with the monoclonal antibody without a conjugate.</p><p>Drug Class: <a href="/books/n/livertox/AntineoplasticAgents/">Antineoplastic Agents</a>, <a href="/books/n/livertox/MonoclonalAntibodies/">Monoclonal Antibodies</a></p><p>Other Monoclonal Antibody Conjugates: Benlantamab Mafodotin, Brentuximab Vedotin, Enfortumab Vedotin, Gemtuzumab Ozogamicin, Inotuzumab Ozogamicin, Polatuzumab Vedotin, Sacituzumab Govitecan, Tisotumab Vedotin, Trastuzumab Deruxtecan</p></div></div><div id="TrastuzumabEmtansine.PRODUCT_INFORMATION"><h2 id="_TrastuzumabEmtansine_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
