Int J Clin Pharm 2024; 46:368-381. [PMID: 38147280 DOI: 10.1007/s11096-023-01671-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Accepted: 11/13/2023] [Indexed: 12/27/2023]
Abstract
BACKGROUND Imatinib, a potent inhibitor of targeted protein tyrosine kinases, treats chronic myeloid leukaemia (CML). Data on imatinib-associated changes in hepatic and thyroid functions are limited and conflicting. AIM To report the prevalence of hepatic and thyroid toxicity associated with the use of imatinib in CML patients. METHOD Articles for the systematic review were selected from electronic databases (PubMed, CINALH, Web of Science). Readily accessible peer-reviewed full articles in English published 1st January 2000 to 18th July 2023 were included. The search terms included combinations of: imatinib, CML, liver toxicity, hepatic toxicity, thyroid toxicity. Screening of titles, abstracts, full text articles was conducted independently by two reviewers. Inclusions and exclusions were recorded following PRISMA guidelines. Detailed reasons for exclusion were recorded. Included articles were critically appraised. RESULTS Ten thousand one hundred and twenty-three CML patients were reported in the 82 included studies corresponding to 21 case reports, 2 case series, 39 clinical trials and 20 observational studies were selected. Excluding case studies/reports, 1268 (12.6%; n = 1268/10046) hepatotoxicity adverse events were reported, of which 64.7% were rated as mild grade I & II adverse events, 363 (28.6%) as severe, grade III and IV adverse events; some led to treatment discontinuation, liver transplantation and fatal consequences. Twenty (35.1%) studies reported discontinuation of imatinib treatment due to the severity of hepatic toxicity. Fourteen (8.4%, n = 14/167) thyroid dysfunction adverse events were reported. CONCLUSION High frequency of mild and severe hepatotoxicity, associated with imatinib in CML patients, was reported in the published literature. Low numbers of mild and manageable thyroid toxicity events were reported.

Anticancer Agents Med Chem 2021; 20:1966-1980. [PMID: 32560620 DOI: 10.2174/1871520620666200619174323] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2019] [Revised: 04/04/2020] [Accepted: 04/08/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Using imatinib, a tyrosine kinase inhibitor drug used in lymphoblastic leukemia, has always had limitations due to its cardiotoxicity and hepatotoxicity side effects. The objective of this study is to develop a target-oriented drug carrier to minimize these adverse effects by the controlled release of the drug. METHODS KIT-5 nanoparticles were functionalized with 3-aminopropyltriethoxysilane and conjugated to rituximab as the targeting agent for the CD20 positive receptors of the B-cells. Then they were loaded with imatinib and their physical properties were characterized. The cell cytotoxicity of the nanoparticles was studied by MTT assay in Ramos (CD20 positive) and Jurkat cell lines (CD20 negative) and their cellular uptake was shown by fluorescence microscope. Wistar rats received an intraperitoneal injection of 50 mg/kg of the free drug or targeted nanoparticles for 21 days. Then the level of aspartate Aminotransferase (AST), alanine Aminotransferase (ALT), Alkaline Phosphatase (ALP) and Lactate Dehydrogenase (LDH) were measured in serum of animals. The cardiotoxicity and hepatotoxicity of the drug were also studied by hematoxylin and eosin staining of the tissues. RESULTS The targeted nanoparticles of imatinib showed to be more cytotoxic to Ramos cells rather than Jurkat cells. The results of the biochemical analysis displayed a significant reduction in AST, ALT, ALP, and LDH levels in animals treated with targeted nanoparticles, compared to the free drug group. By comparison with the free imatinib, histopathological results represented less cardiotoxicity and hepatotoxicity in the animals, which received the drug through the current designed delivery system. CONCLUSION The obtained results confirmed that the rituximab targeted KIT-5 nanoparticles are promising in the controlled release of imatinib and could decrease its cardiotoxicity and hepatotoxicity side effects.

[PMID: 33161366 DOI: 10.1016/j.critrevonc.2020.103127] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Revised: 09/29/2020] [Accepted: 10/05/2020] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Multikinase inhibitors (MKI) are targeted molecular agents that have revolutionized cancer management. However, there is a paucity of data concerning MKI-related liver injury risk and clinical guidelines for the management of liver toxicity in patients receiving MKI for cancer are scarce. DESIGN We conducted a PubMed search of articles in English published from January 2000 to December 2018 related to hepatotoxicity of the 29 FDA-approved MKIs at doses used in clinical practice. The search terms were the international non-proprietary name of each agent cross-referenced with «hepatotoxicity», «hepatitis», «hepatic adverse event», or «liver failure», and «phase II clinical trial», «phase III clinical trial», or «case report». RESULTS Following this search, 140 relevant studies and 99 case reports were considered. Although asymptomatic elevation of aminotransferase levels has been frequently observed in MKI clinical trials, clinically significant hepatotoxicity is a rare event. In most cases, the interval between treatment initiation and the onset of liver injury is between one week and two months. Liver toxicity is often hepatocellular and less frequently mixed. Life-threatening MKI-induced hepatic injury has been described, involving fulminant liver failure or death. Starting from existing data, a description of MKI-related liver events, grading of hepatotoxicity risk, and recommendations for management are also given for various MKI molecules. CONCLUSION All MKIs can potentially cause liver injury, which is sometimes irreversible. As there is still no strategy available to prevent MKI-related hepatotoxicity, early detection remains crucial. The surveillance of liver function during treatment may help in the early detection of hepatotoxicity. Furthermore, the exclusion of potential causes of hepatic injury is essential to avoid unnecessary MKI withdrawal.

Abstract
Purpose Although imatinib-induced hepatotoxicity may aggravate the patient’s clinical condition and alter the treatment plan, the underlying mechanism of and factors influencing imatinib-induced hepatotoxicity have rarely been investigated. The purpose of this study was to investigate factors affecting on the incidence of hepatotoxicity within 90 days after starting imatinib treatment and time to onset of imatinib-induced hepatotoxicity. Materials and Methods We retrospectively evaluated the records of 177 patients receiving imatinib from October 2012 to September 2017. The analyzed factors included sex, age, body weight, body surface area, underlying disease, and concomitant drugs. Results The proportion of patients with hepatotoxicity within 90 days after imatinib administration was 33.9%. Proton pump inhibitors (PPIs) increased the incidence of hepatotoxicity approximately 3.8-fold and doubled the hazard of time to reach hepatotoxicity. Patients with liver disease or hepatitis B virus (HBV) carriers had a more than 8-fold higher risk of hepatotoxicity and a 5.2-fold increased hazard of hepatotoxicity compared to those without liver disease or HBV. Patients with body weight under 55 kg had a 2.2-fold higher risk for occurrence of hepatotoxicity. Patients with an imatinib dose > 400 mg had a 2.3-fold increased hazard of time to reach hepatotoxicity compared to those with an imatinib dose ≤ 400 mg. Conclusion The findings of this study suggest that the use of PPIs and presence of liver disease or HBV were associated with imatinib-induced hepatotoxicity. Thus, close liver function monitoring is recommended, especially in patients with liver impairment or using PPIs.

Hucke A, Ciarimboli G. The Role of Transporters in the Toxicity of Chemotherapeutic Drugs: Focus on Transporters for Organic Cations. J Clin Pharmacol 2017; 56 Suppl 7:S157-72.

Abstract
The introduction of chemotherapy in the treatment of cancer is one of the most important achievements of modern medicine, even allowing the cure of some lethal diseases such as testicular cancer and other malignant neoplasms. The number and type of chemotherapeutic agents available have steadily increased and have developed until the introduction of targeted tumor therapy. It is now evident that transporters play an important role for determining toxicity of chemotherapeutic drugs not only against target but also against nontarget cells. This is of special importance for intracellularly active hydrophilic drugs, which cannot freely penetrate the plasma membrane. Because many important chemotherapeutic agents are substrates of transporters for organic cations, this review discusses the known interaction of these substances with these transporters. A particular focus is given to the role of transporters for organic cations in the development of side effects of chemotherapy with platinum derivatives and in the efficacy of recently developed tyrosine kinase inhibitors to specifically target cancer cells. It is evident that specific inhibition of uptake transporters may be a possible strategy to protect against undesired side effects of platinum derivatives without compromising their antitumor efficacy. These transporters are also important for efficient targeting of tyrosine kinase inhibitors to cancer cells. However, in order to achieve the aims of protecting from undesired toxicities and improving the specificity of uptake by tumor cells, an exact knowledge of transporter expression, function, regulation under normal and pathologic conditions, and of genetically and epigenetically regulation is mandatory.

Abstract
Chronic myeloid leukemia (CML) is a hematologic neoplasm with a progressive, ultimately terminal, disease course. In most cases, CML arises owing to the aberrant formation of a chimeric gene for a constitutively active tyrosine kinase. Inhibition of the signaling activity of this kinase has proved to be a highly successful treatment target, transforming the prognosis of patients with CML. New tyrosine kinase inhibitors continue to improve the management of CML, offering alternative options for those resistant to or intolerant of standard tyrosine kinase inhibitors. Here we review the pathobiology of CML and explore emerging strategies to optimize the management of chronic-phase CML, particularly first-line treatment.

Abstract
The aim of this study was to evaluate and compare the effects of imatinib and nilotinib to that of silymarin on established liver fibrosis and oxidative stress in a thioacetamide (TAA) rat model. Male Wistar rats received intraperitoneal (i.p.) injections of TAA (150mg/kg, twice weekly) for 12weeks. Daily treatments with imatinib (10mg/kg), nilotinib (10mg/kg), and silymarin (100mg/kg) were administered orally during the last 4weeks of TAA-administration. At the end of the study, hepatic damage was evaluated by analysis of liver function tests in serum. Hepatic histopathology and collagen content were employed to quantify liver fibrosis. Hepatic oxidative stress was assessed by measuring malondialdehyde (MDA), 4-hydroxynonenal (4-HNE), total nitrate/nitrite (NOx), and reduced glutathione (GSH) contents, as well as myeloperoxidase (MPO) and superoxide dismutase (SOD) activities. Nilotinib, silymarin and, to a lesser extent, imatinib treatments ameliorated TAA-induced hepatic oxidative stress and damage as indicated by hepatic MDA, 4-HNE, NOx, GSH, MPO and SOD levels, as well as liver function tests. Hepatic histopathology results revealed that nilotinib, imatinib, and silymarin treatments decreased the mean score of fibrosis in TAA-treated rats by 24, 14, and 3%, respectively. However, nilotinib and silymarin, but not imatinib, treatments decreased hepatic collagen content in TAA-treated rats by 17 and 36%, respectively. In conclusion, we demonstrated for the first time that nilotinib not only protected against hepatic oxidative stress, but also slowed down liver fibrosis progression. Thus, we provide the first evidence that nilotinib might be a promising anti-fibrotic drug.

Abstract
Effective and well-tolerated anti-fibrotic drugs are currently lacking. Therefore, this study was carried out to investigate the potential anti-fibrotic effects of imatinib, nilotinib and silymarin on established hepatic fibrosis in the carbon tetrachloride (CCl(4)) rat model. Male Wistar rats received intraperitoneal injections of CCl(4) twice weekly for 8weeks, as well as daily intraperitoneal treatments of imatinib (10 and 20mg/kg), nilotinib (10 and 20mg/kg) and silymarin (100mg/kg) during the last 4weeks of CCl(4)-intoxication. At the end of the study, hepatic damage was evaluated by analysis of liver function tests and hepatic oxidative stress parameters. Hepatic fibrosis was evaluated by histopathology and morphometry, as well as collagen and 4-hydroxyproline contents. Nilotinib (20mg/kg) was the most effective treatment to counteract CCl(4)-induced hepatic injury as indicated by liver function tests and histopathology. Nilotinib (10mg/kg), nilotinib (20mg/kg) and silymarin (100mg/kg) treatments reduced the mean score of hepatic fibrosis by 31%, 68% and 47%, respectively, and hepatic collagen content by 47%, 49% and 18%, respectively in CCl(4)-treated rats. Hepatic morphometric evaluation and 4-hydroxyproline content revealed that CCl(4)-induced fibrosis was ameliorated significantly by nilotinib (20mg/kg) and imatinib (20mg/kg). Unlike nilotinib, imatinib (20mg/kg) showed some sort of hepatic injury evidenced by elevation of serum aminotransferases and total bilirubin levels, and hepatic total nitrate/nitrite content, as well as characteristic anisonucleosis visualized with the hematoxylin-eosin staining. In conclusion, this study provides the evidence that nilotinib exerts anti-fibrotic activity and suggests that it may be valuable in the treatment of hepatic fibrosis in humans.

Abstract
Imatinib mesylate is a drug that has been approved for treatment of chronic myeloid leukemia, Philadelphia-positive acute lymphoblastic leukemia, and advanced gastrointestinal stromal tumors. Several cases of hepatotoxicity, including fatal liver failure, have been reported with the long-term use of imatinib mesylate. Generally hepatotoxicity resolves after discontinuation of imatinib. Despite discontinuation of imatinib, hepatotoxicity can be progressive. Steroid may be useful in these patients and should be started early. We report a 53-year-old woman with advanced gastrointestinal stromal tumors who developed hepatotoxicity while receiving imatinib and subsequently acute liver failure. Ten weeks after commencing imatinib treatment, hepatotoxicity was determined. Imatinib was immediately ceased. Subsequently, a week later hepatic encephalopathy, jaundice, and coagulopathy occurred. Prednisolone was commenced. Liver biopsy was performed five weeks after the determining of hepatotoxicity. Biopsy showed sinusoidal congestion, necrosis of hepatocytes, inflammation, and hepatocyte drop out around the hepatic venule consistent with drug toxicity. Her liver function tests normalized with a nine-week prednisolone treatment. The patient was discharged. Her liver enzymes remained in normal range following visits. In cases of imatinib-induced acute hepatitis, the administration of prednisolone may be useful in the resolution of the acute episode and allow the reintroduction of a drug without risking recurrence of hepatitis.

Abstract
Imatinib is currently the treatment of choice in chronic myeloid leukemia. The use of this drug is safe, although some cases of imatinib-induced toxic hepatitis have been reported. We present 2 patients treated with this drug who developed acute anicteric hepatitis months after starting treatment. We also review 20 reports of individual cases to characterize imatinib-induced hepatitis. Imatinib-induced hepatitis has a variable latency period, frequently of several months. Half of the patients develop anicteric hepatitis and the clinical course is generally benign. A distinguishing feature of this entity is a transitory increase in transaminase levels in patients diagnosed with hepatitis in the weeks after treatment withdrawal. Resumption of imatinib use provokes hepatitis recurrence, which can be avoided by simultaneous prednisone administration.

Abstract
Although hepatotoxicity is a frequent concern with all medications, chemotherapeutic agents are more often implicated in causing liver damage than most other drug classes. In many instances, these reactions are considered dose related because cytotoxic therapy directed at rapidly growing cancer cells may readily impact hepatocytes even though they are dividing more slowly. Because the stakes (remission of cancer) are high, so are the risks that the oncologist and the patient are willing to assume. The dose of many chemotherapeutic agents is limited by the toxic effects on the lungs, bone marrow, kidneys, and gastrointestinal system, including the liver. An awareness of the toxic potential of each chemotherapeutic agent is necessary before initiation of new oncologic treatments.
