<meta name="description" content="Bendamustine is a parenterally administered alkylating agent used alone and in combination with other antineoplastic agents in the treatment of chronic lymphocytic leukemia and refractory forms of non-Hodgkin lymphoma. Bendamustine therapy is associated with minor transient serum enzyme elevations during treatment and to rare instances of clinically apparent liver injury, with jaundice generally arising as a part of a generalized hypersensitivity syndrome. Bendamustine also has potent immunosuppressive activity and can cause reactivation of chronic hepatitis B that can be severe and even fatal.">

id="Bendamustine.Introduction"><h3>Introduction</h3><p>Bendamustine is a parenterally administered alkylating agent used alone and in combination with other antineoplastic agents in the treatment of chronic lymphocytic leukemia and refractory forms of non-Hodgkin lymphoma. Bendamustine therapy is associated with minor transient serum enzyme elevations during treatment and to rare instances of clinically apparent liver injury, with jaundice generally arising as a part of a generalized hypersensitivity syndrome. Bendamustine also has potent immunosuppressive activity and can cause reactivation of chronic hepatitis B that can be severe and even fatal.</p></div><div id="Bendamustine.Background"><h3>Background</h3><p>Bendamustine (ben" da mus' teen) is a relatively novel alkylating agent with a benzimidazole ring giving it purine analogue-like properties. Like other alkylating agents, bendamustine is thought to act by modifying and cross linking purine bases in DNA, thus inhibiting DNA, RNA and protein synthesis and leading to cell death in rapidly dividing cells. Bendamustine appears to have a special activity against B cell leukemias and lymphomas. Bendamustine was approved for use in the United States in 2008 as therapy for chronic lymphocytic leukemia, and indications were later expanded to include indolent B cell non-Hodgkin lymphoma that is refractory to rituximab containing regimens. Bendamustine is given intravenously and is available in liquid formulations (45 and 180 mg vials: 90 mg/mL) and as powder for reconstitution (25 or 100 mg in a single use vial) generically and under the trade name Treanda. Recommended doses vary by age, body weight and malignant condition. Bendamustine is often given in combination with other antineoplastic agents on days 1 and 2 of 21- or 28-day cycles. The toxicity of bendamustine is similar to that of other alkylating agents. Common side effects include bone marrow suppression, nausea, vomiting, diarrhea, anorexia, fatigue, dizziness and hypersensitivity rashes. Serious adverse events include severe myelosuppression, bacterial infections, infusion reactions, local extravasation injury, anaphylaxis, tumor lysis syndrome and Stevens Johnson syndrome.</p></div><div id="Bendamustine.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>Mild and transient elevations in serum aminotransferase levels are found in up to 20% of patients treated with bendamustine, but elevations above 5 times the upper limit of normal occur in less than 3% of patients. The abnormalities are generally transient, unaccompanied by symptoms and rarely require dose modification. Clinically apparent liver injury from bendamustine has been limited to a small number of cases of mild hepatitis with features of hypersensitivity including eosinophilia, rash or other systemic symptoms. Autoantibody formation is uncommon. The course is generally self-limited, but may require corticosteroid therapy for control of symptoms and timely recovery.</p><p>Bendamustine therapy has also been implicated in causing reactivation of hepatitis B in patients with anti-HBc in serum with or without HBsAg. In several instances patients were also receiving corticosteroids or rituximab, yet had received these without reactivation in the past. Reactivation arose after 2 to 6 cycles of bendamustine chemotherapy, presenting with symptoms accompanied by HBsAg and rising levels of HBV DNA in serum. Reactivation was generally self-limited and patients later became HBsAg negative. In one instance, however, the course was severe and resulted in death from acute liver failure.</p><p>Likelihood score: C (probable cause of clinically apparent liver injury, some of which is due to reactivation of hepatitis B).</p></div><div id="Bendamustine.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The mild serum aminotransferase elevations that occur with bendamustine therapy are most likely due to direct hepatotoxicity and are generally mild, asymptomatic and resolve without dose modification or intervention. The more clinically apparent forms of bendamustine hepatotoxicity are likely due to hypersensitivity. Bendamustine is rarely used in myeloablative regimens in preparation of hematopoietic cell transplantation and has not been linked to cases of sinusoidal obstruction syndrome, although in high enough doses it is likely to cause sinusoidal cell injury as do other alkylating agents. Bendamustine also appears to be capable of causing reactivation of hepatitis B, probably because of its potent immunosuppressive activity. Bendamustine is extensively metabolized by the hepatic cytochrome P450 system, predominantly CYP 1A2, and may be susceptible to drug-drug interactions with agents that induce or inhibit CYP 1A2 activity.</p></div><div id="Bendamustine.Outcome_and_Management"><h3>Outcome and Management</h3><p>The severity of liver injury from bendamustine ranges from mild elevations in liver enzymes to anicteric, but symptomatic hepatitis to clinically apparent hepatitis with jaundice. Monitoring of liver tests during therapy is recommended. Cases of acute liver failure, chronic hepatitis or vanishing bile duct syndrome have not been reported. Patients with hypersensitivity reactions to bendamustine should not be reexposed to the agent. There is no information on the cross reactivity of hypersensitivity reactions to bendamustine with other alkylating agents such as mechlorethamine (nitrogen mustard), carmustine (CCNU), lomustine (BCNU), chlorambucil and cyclophosphamde. Because bendamustine can cause reactivation of hepatitis B, patients should be screened for HBsAg and anti-HBc before starting therapy and either offered prophylaxis with agents active against hepatitis B (entecavir, tenofovir) or monitored closely for HBV DNA levels and started on therapy if viral titers rise.</p><p>Drug Class: <a href="/books/n/livertox/AntineoplasticAgents/?report=reader">Antineoplastic Agents</a>, <a href="/books/n/livertox/AlkylatingAgents/?report=reader">Alkylating Agents</a></p></div></div><div id="Bendamustine.CASE_REPORT"><h2 id="_Bendamustine_CASE_REPORT_">CASE REPORT</h2><div id="Bendamustine.Case_1._Acute_hypersensitiv"><h3>Case 1. Acute hypersensitivity reaction with hepatitis attributed to bendamustine</h3><p>[Modified from: Jo T, Horio K. Severe liver damage and nonallergic bronchitis with eosinophilia in a patient with follicular lymphoma treated with bendamustine plus rituximab. Case Rep Oncol 2014; 7: 497-502. <a href="https://www.ncbi.nlm.nih.gov/pubmed/25232317" ref="pagearea=body&targetsite=external&targetcat=link&targettype=uri">PubMed Citation</a>].</p><p>A 66 year old woman with follicular lymphoma developed cough and liver test abnormalities 16 days after starting an initial cycle of bendamustine and rituximab. She had the recent diagnosis of stage IIIa follicular lymphoma with multiple lymph node involvement. After a first course of R-CHOP therapy, she refused further courses because of peripheral neuropathy, alopecia and fatigue. For these reasons, she was switched to rituximab (375 mg/m<sup>2</sup> on day 1) and bendamustine (75 mg/m<sup>2</sup> on days 2 and 3 of planned 21 day cycles). She developed a severe cough that caused insomnia and fatigue and was found to have bronchitis and liver test abnormalities with ALT 93 U/L, AST 133 U/L, alkaline phosphatase 274 U/L and bilirubin 0.7 mg/dL. She had no history of smoking, drug allergies or know exposure to hepatitis. Tests for acute hepatitis A, B and C were negative as were assays for CMV and mycoplasma infection. Imaging of the liver was normal and a CT scan of the chest showed no evidence of pneumonitis. Her cough continued, but cultures were negative and she was evidently afebrile. At the same time liver tests worsened; serum bilirubin rising to 6.2 mg/dL, ALT to 577 U/L and alkaline phosphatase to 932 U/L (Table). Peripheral eosinophil counts, that had been normal initially, began to rise (peaking at 36%). Because of worsening symptoms and laboratory test results suggesting a hypersensitivity reaction, she was treated with a short course of high dose methylprednisolone and improved rapidly. She was switched to oral prednisone which was gradually reduced in dose and then discontinued. In follow up, her cough resolved and liver tests were normal. Bendamustine was not restarted.</p><div id="Bendamustine.Key_Points"><h4>Key Points</h4><div class="iconblock whole_rhythm clearfix ten_col table-wrap" id="figBendamustineT1"><a href="/books/NBK548108/table/Bendamustine.T1/?report=objectonly" target="object" title="Table" class="img_link icnblk_img figpopup" rid-figpopup="figBendamustineT1" rid-ob="figobBendamustineT1"><img class="small-thumb" src="/books/NBK548108/table/Bendamustine.T1/?report=thumb" src-large="/books/NBK548108/table/Bendamustine.T1/?report=previmg" alt="Image " /></a><div class="icnblk_cntnt"><h4 id="Bendamustine.T1"><a href="/books/NBK548108/table/Bendamustine.T1/?report=objectonly" target="object" rid-ob="figobBendamustineT1">Table</a></h4></div></div></div><div id="Bendamustine.Laboratory_Values"><h4>Laboratory Values</h4><div class="iconblock whole_rhythm clearfix ten_col table-wrap" id="figBendamustineT2"><a href="/books/NBK548108/table/Bendamustine.T2/?report=objectonly" target="object" title="Table" class="img_link icnblk_img figpopup" rid-figpopup="figBendamustineT2" rid-ob="figobBendamustineT2"><img class="small-thumb" src="/books/NBK548108/table/Bendamustine.T2/?report=thumb" src-large="/books/NBK548108/table/Bendamustine.T2/?report=previmg" alt="Image " /></a><div class="icnblk_cntnt"><h4 id="Bendamustine.T2"><a href="/books/NBK548108/table/Bendamustine.T2/?report=objectonly" target="object" rid-ob="figobBendamustineT2">Table</a></h4></div></div></div><div id="Bendamustine.Comment"><h4>Comment</h4><p>A woman with follicular lymphoma developed a hypersensitivity reaction within 2 weeks of starting an initial cycle of rituximab and bendamustine. The major symptoms were cough and fatigue which appeared to be due to an allergic bronchitis. Accompanying this was a mild hepatitis that nevertheless progressed to jaundice and was accompanied by a rising eosinophilia. Treatment with corticosteroids rapidly brought the hypersensitivity reaction under control and her liver tests were normal within 4 to 6 weeks and remained normal even with tapering and discontinuation of corticosteroids. There was evidently no rash or fever, so that the reaction is best described as “drug-hypersensitivity with systemic symptoms” rather than DRESS syndrome. One might hypothesize that rituximab altered the clinical expression of the hypersensitivity reaction. Hypersensitivity reactions (usually rash) are not infrequent with bendamustine therapy (1% to 4%) but are generally mild and self-limited, although rare instances of Stevens Johnson syndrome have been reported.</p></div></div></div><div id="Bendamustine.PRODUCT_INFORMATION"><h2 id="_Bendamustine_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><div id="Bendamustine.BPI" class="box boxed-text-box whole_rhythm hide-overflow"><p>
