Eculizumab has been linked to several instances of serum enzyme elevations after repeated infusions and to rare instances of clinically apparent acute liver injury.</p></div><div id="Eculizumab.Background"><h3>Background</h3><p>Eculizumab (e" kue liz' ue mab) is a recombinant, humanized IgG monoclonal antibody to complement factor 5, which inhibits its enzymatic cleavage and activation. Activated complement is an important mediator of immune damage including hemolysis of red blood cells and plays an essential role in the hemolysis and tissue damage that accompanies paroxysmal nocturnal hemoglobinuria (PNH) and hemolytic uremic syndrome (HUS). In clinical trials in PNH, eculizumab was found to reduce hemolysis and the need for blood transfusions with subsequent improvement in symptoms and quality of life. Eculizumab was approved for use in PNH in the United States in 2007. The indications were later broadened to include atypical hemolytic uremic syndrome with complement-mediated thrombotic events in 2011. Eculizumab is available as a solution in single dose vials of 300 mg in 30 mL (10 mg/mL) under the commercial name Soliris. The recommended dose varies by body weight and indication, but it is typically given by intravenous infusion (over 35 minutes) weekly for 5 weeks and every two weeks thereafter. Side effects are not common, but can include headache, diarrhea, nausea, fatigue and upper respiratory tract infections. Rare, but potentially severe adverse reactions include serious infections, including meningococcal infections, for which reason eculizumab is available only as a part of a risk evaluation and mitigation strategy (REMS) that requires physician training in its use and enrollment of the patient in a surveillance program.</p></div><div id="Eculizumab.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>In clinical trials of eculizumab in patients with PNH and atypical HUS, serum enzyme levels were rarely mentioned and laboratory test results were described as being stable or unremarkable. In preregistration studies of eculizumab there were no reports of clinically apparent liver injury with jaundice. Indeed, in many studies, a steady improvement in <a class="def" href="/books/n/livertox/glossary/def-item/glossary.alanine-aminotransferase-alt-/">ALT</a> and <a class="def" href="/books/n/livertox/glossary/def-item/glossary.aspartate-aminotransferase-ast-/">AST</a> values during treatment was described, perhaps reflecting the decrease in intravascular hemolysis that occurred. After approval and more widespread use of eculizumab, however, a case series of eculizumab therapy in 11 children with atypical HUS, reported that 5 children developed marked serum enzyme elevations during therapy that was accompanied by jaundice in three cases and led to discontinuation of treatment in one patient after development of symptoms and jaundice (Case 1). The onset of injury was within the first 4 doses of eculizumab and tended to recur with subsequent doses, but to a lesser extent. Indeed, 4 children were able to continue eculizumab therapy without recurrence. The pattern of serum enzyme elevations was mixed. There was no mention of immunoallergic symptoms or autoantibody formation. Similar cases have not been reported in other case series or clinical trials. Thus, liver injury may occur with eculizumab therapy but it is typically mild, asymptomatic and self-limited in course, not requiring dose modification or discontinuation. There have been no reports of acute liver failure, chronic hepatitis or vanishing bile duct syndrome associated with eculizumab therapy.</p><p><a class="def" href="/books/n/livertox/glossary/def-item/glossary.likelihood-score/">Likelihood score</a>: D (possible cause of clinically apparent liver injury).</p></div><div id="Eculizumab.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The mechanism by which eculizumab might cause liver injury is unknown. Eculizumab is a monoclonal antibody and, like other proteins, is metabolized into amino acids and is unlikely to have intrinsic toxicity. Because it blocks the activation of complement, it might predispose to conditions that depend on complement activation for resolution (such as meningococcemia), but it is not clear whether this applies to any liver diseases.</p></div><div id="Eculizumab.Outcome_and_Management"><h3>Outcome and Management</h3><p>Eculizumab therapy has been linked to rare instances of mild, transient serum enzyme elevations during therapy, typically arising 1 to 3 weeks after an initial or early infusion of the monoclonal antibody.

Tests for viral hepatitis and autoimmune markers were negative and liver ultrasound showed hepatomegaly and an heterogenous liver texture, but no evidence of biliary obstruction. A liver biopsy showed minimal changes with mild hepatocellular cytoplasmic swelling and clearing, mild Kupffer cell hemosiderosis, mild pericentral sinusoidal dilation and fibrosis. Serum enzyme elevations soon fell into the normal range and he received a third infusion 3 weeks after the second. Three days later, his serum enzymes were again elevated and he was jaundiced with a direct bilirubin of 9.9 mg/dL (previously 0.0). Therapy was suspended and liver tests began to improve and were reportedly normal 4 weeks later.</p><div id="Eculizumab.Key_Points"><h4>Key Points</h4><div id="Eculizumab.T1" class="table"><p class="large-table-link" style="display:none"><span class="right"><a href="/books/NBK547839/table/Eculizumab.T1/?report=objectonly" target="object">View in own window</a></span></p><div class="large_tbl" id="__Eculizumab.T1_lrgtbl__"><table><tbody><tr><td rowspan="1" colspan="1" style="vertical-align:top;">Medication:</td><td rowspan="1" colspan="1" style="vertical-align:top;">Eculizumab (900 mg infusions)</td></tr><tr><td rowspan="1" colspan="1" style="vertical-align:top;">Pattern:</td><td rowspan="1" colspan="1" style="vertical-align:top;">Mixed (R=2.6 from peak values)</td></tr><tr><td rowspan="1" colspan="1" style="vertical-align:top;">Severity:</td><td rowspan="1" colspan="1" style="vertical-align:top;">3+ (jaundice, hospitalization)</td></tr><tr><td rowspan="1" colspan="1" style="vertical-align:top;"><a class="def" href="/books/n/livertox/glossary/def-item/glossary.latency/">Latency</a>:</td><td rowspan="1" colspan="1" style="vertical-align:top;">11 days</td></tr><tr><td rowspan="1" colspan="1" style="vertical-align:top;">Recovery:</td><td rowspan="1" colspan="1" style="vertical-align:top;">4 weeks</td></tr><tr><td rowspan="1" colspan="1" style="vertical-align:top;">Other medications:</td><td rowspan="1" colspan="1" style="vertical-align:top;">None mentioned</td></tr></tbody></table></div></div></div><div id="Eculizumab.Comment"><h4>Comment</h4><p>In a small case series, 5 of 11 children with atypical HUS treated with eculizumab developed evidence of liver injury after 1 to 4 doses of the monoclonal antibody. All five were known to have had normal serum enzymes before starting treatment and in several instances the elevations recurred with a subsequent infusion. Nevertheless, all except the case described here recovered and were able to tolerate further doses of eculizumab without recurrence of liver injury. This article is the only description of liver injury from this monoclonal antibody and came as a surprise, because of the lack of hepatotoxicity noted in previous publications despite careful descriptions of several hundred patients with either HUS or PND who received eculizumab. The pattern of injury was "mixed" with marked elevations in aminotransferase as well as alkaline phosphatase and <a class="def" href="/books/n/livertox/glossary/def-item/glossary.gamma-glutamyl-transpeptidase-ggt-/">GGT</a> levels. Also striking was the rapidity of onset and rapidity of resolution suggesting a direct effect on hepatic function rather than hepatocellular damage. A liver biopsy was performed, but at a time when the abnormalities had almost resolved. The biopsy showed hepatocellular swelling rather than necrosis and cell loss. Thus, the liver injury attributed to eculizumab is unusual and suggestive of a direct effect of the monoclonal antibody on hepatocyte pathways rather than direct cell damage.</p></div></div></div><div id="Eculizumab.PRODUCT_INFORMATION"><h2 id="_Eculizumab_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><div id="Eculizumab.BPI" class="box"><p>
