id="Infigratinib.Introduction"><h3>Introduction</h3><p>Infigratinib is a FGF receptor kinase inhibitor that is used in the treatment of unresectable, locally advanced or metastatic intrahepatic cholangiocarcinoma. Infigratinib is associated with transient and usually mild elevations in serum aminotransferase during therapy, but has not been convincingly linked to cases of clinically apparent liver injury.</p></div><div id="Infigratinib.Background"><h3>Background</h3><p>Infigratinib (fue” ti ba’ ti nib) is an orally available, specific inhibitor of the fibroblast growth factor (FGF) receptor 1, 2 and 3 kinases, that is used in the therapy advanced or metastatic cholangiocarcinoma. Aberrant FGF receptor signaling is associated with several cancer types in which amplifications, translocations, fusings, and other activating point mutations of FGF receptors are found. Cholangiocarcinomas often harbor mutants of the FGF receptor 2 that cause the activation of FGF pathways that promote uncontrolled growth and tumorigenesis. Inhibition of the mutant receptor causes regression of cell proliferation and promotes cell death. Studies in cell culture and in animal models suggested that infigratinib was active in inhibiting cancer cell growth. Trials in patients with cholangiocarcinoma demonstrated a significant overall durable response rate, for which reason infigratinib received accelerated approval for use in the United States in 2021. Current indications are limited to adults with previously treated, unresectable, locally advanced, or metastatic intrahepatic cholangiocarcinoma with FGF receptor 2 gene fusions or other rearrangements. Infigratinib continues to be under evaluation for its long term safety and efficacy in cholangiocarcinoma and for its possible efficacy in other forms of cancer associated with FGF receptor gene alternations. Infigratinib is available in capsules of 25 and 100 mg under the brand name Truseltiq. The recommended dose is 125 mg once daily for 21 days of a 28 day cycle, continued indefinitely or until there is disease progression or unacceptable toxicity. Adverse events are common and include hyperphosphatemia (an effect of inhibition of FGF signaling), as well as symptoms of fatigue, nausea, diarrhea, constipation, dysgeusia, anorexia, abdominal pain, musculoskeletal pain, dizziness, alopecia, dryness of the eyes, mouth and skin, blurred vision, nail toxicity, and hand-foot syndrome. Severe adverse events include severe hyperphosphatemia, ocular toxicity, infections and sepsis, and embryo-fetal toxicity.</p></div><div id="Infigratinib.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>In the open label clinical trials of infigratinib for advanced or metastatic cholangiocarcinoma, adverse events were common and led to dose interruptions in 64%, dose reductions in 60% of patients, and permanent discontinuations in 15% largely for hyperphosphatemia, infections and sepsis rather than liver injury. In preregistration trials in 108 patients, ALT elevations arose in 51% and to above 5 times ULN in 6%. The elevations were typically self-limited and resolved rapidly with or without dose adjustments. No patients developed clinically apparent liver injury or jaundice. Since its approval, there have been no reports clinically apparent liver injury attributed to infigratinib. However, the total clinical experience with its use has been limited and the frequency of serum aminotransferase elevations during therapy suggest that clinically significant liver injury may occur.</p><p>Likelihood score: E* (unproven but possible, rare cause of clinically apparent liver injury).</p></div><div id="Infigratinib.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The causes of serum enzyme elevations or liver injury from infigratinib therapy are not known. Some of the adverse effects of infigratinib are due to its effects on FGF signaling (hyperphosphatemia) and others may be due to off-target effects on other kinases. Infigratinib is metabolized in the liver largely by CYP 3A4 and liver injury might be caused by production of a toxic or immunogenic intermediate. Because it is a substrate for CYP 3A4, infigratinib is susceptible to drug-drug interactions with agents that inhibit or induce this specific hepatic microsomal activity.</p></div><div id="Infigratinib.Outcome_and_Management"><h3>Outcome and Management</h3><p>Infigratinib is associated with a moderate rate of serum aminotransferase elevations that are generally transient and not associated with symptoms or jaundice. While regular monitoring of liver tests is not specifically recommended during infigratinib therapy, elevations if confirmed should lead to more careful follow up monitoring. Serum aminotransferase elevations above 5 times the upper limit of normal (if confirmed) or any elevations accompanied by jaundice or symptoms should lead to dose reduction or temporary cessation until the abnormalities resolve or an alternative cause is identified. There is no evidence to suggest a cross reactivity in risk for adverse events, hypersensitivity or hepatic injury between infigratinib and other protein kinases or FGF receptor inhibitors.</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><p>Other FGF Receptor Kinase Inhibitors: <a href="/books/n/livertox/Erdafitinib/?report=reader">Erdafitinib</a>, <a href="/books/n/livertox/Futibatinib/?report=reader">Futibatinib</a>, <a href="/books/n/livertox/Pemigatinib/?report=reader">Pemigatinib</a></p></div></div><div id="Infigratinib.PRODUCT_INFORMATION"><h2 id="_Infigratinib_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
