Application and Resistance Mechanisms of Lenvatinib in Patients with Advanced Hepatocellular Carcinoma.

ABSTRACT: Lenvatinib, a multitargeted tyrosine kinase inhibitor (TKI), is one of the preferred targeted drugs for the treatment of advanced hepatocellular carcinoma (aHCC). Since the REFLECT study showed that lenvatinib was noninferior to sorafenib in overall survival (OS), lenvatinib monotherapy has been widely used for aHCC. Moreover, lenvatinib combination therapy, especially lenvatinib combined with immune checkpoint inhibitors (ICIs), has shown more encouraging clinical results. However, drug development and comprehensive treatment have not significantly improved the prognosis, and lenvatinib resistance is often encountered in treatment. The underlying molecular mechanism of lenvatinib resistance is still unclear, and studies to solve drug resistance are ongoing. The molecular mechanisms of lenvatinib resistance in patients with aHCC include the regulation of signaling pathways, the regulation of noncoding RNAs, the impact of the immune microenvironment, tumor stem cell activation and other mechanisms. This review aims to (1) summarize the progress of lenvatinib in treating aHCC, (2) delineate the known lenvatinib resistance mechanisms of current therapy, and (3) describe the development of therapeutic methods intended to overcome these resistance mechanisms.

Project description:BackgroundThere is no standard posttreatment for patients with advanced hepatocellular carcinoma (HCC) in whom lenvatinib therapy has failed. This study aimed to investigate rates of migration to posttreatment after lenvatinib and to explore candidates for second-line agents in the patients with failed lenvatinib therapy.MethodsWe retrospectively collected data on patients with advanced HCC who received lenvatinib as the first-line agent in 7 institutions.ResultsOverall survival and progression-free survival (PFS) of 178 patients who received lenvatinib as the first-line agent were 13.3 months (95% confidence interval [CI], 11.5-15.2) and 6.7 months (95% CI, 5.6-7.8), respectively. Sixty-nine of 151 patients (45.7%) who discontinued lenvatinib moved on to posttreatment. The migration rates from lenvatinib to the second-line agent and from the second-line agent to the third-line agent were 41.7 and 44.4%, respectively. Based on multivariate analysis, response to lenvatinib (complete or partial response according to modified RECIST) and discontinuation of lenvatinib due to radiological progression, as well as male were associated with a significantly higher probability of migration to posttreatment after lenvatinib. On the other hand, alpha-fetoprotein levels of 400 ng/mL or higher was correlated with a significantly lower probability of migration to posttreatment after lenvatinib. Of 63 patients who received second-line systemic therapy, 53 (84.2%) were administered sorafenib. PFS, objective response rate (ORR), and disease control rate (DCR) for sorafenib treatment were 1.8 months (95% CI, 0.6-3.0), 1.8%, and 20.8%, respectively. According to the Cox regression hazard model, Child-Pugh class B significantly contributed to shorter PFS. PFS, ORR, and DCR of 22 patients who received regorafenib after lenvatinib in any lines were 3.2 months (range, 1.5-4.9 months), 13.6%, and 36.3%, respectively. Similarly, PFS, ORR, and DCR of 17 patients who received regorafenib after lenvatinib in the third-line (after sorafenib) were 3.8 months (range, 1.1-6.5 months), 17.6%, and 41.2%, respectively.ConclusionSorafenib may not be a candidate for use as a posttreatment agent after lenvatinib, according to the results of the present study. Regorafenib has the potential to become an appropriate posttreatment agent after lenvatinib.

Project description:BackgroundGiven the significant advancements in the management of hepatocellular carcinoma (HCC) and the emergence of novel treatment approaches, establishing reliable predictors has become crucial for optimizing patient selection and therapeutic sequencing in HCC. In this study, we aimed to investigate the prognostic factors and treatment efficacy associated with lenvatinib-based therapy.MethodsWe retrospectively enrolled 53 patients receiving lenvatinib monotherapy, and 19 patients receiving lenvatinib plus immune checkpoint inhibitor combination therapy as their first-line systemic treatment for unresectable HCC at a single medical center. We employed univariate and multivariate Cox regression analyses to ascertain the factors influencing survival in these cohorts.ResultsFor lenvatinib monotherapy and the combination therapy, the objective response rates were 30.2% and 63.2%, respectively (P=0.03); the median progression-free survival (PFS) durations were 7 months [95% confidence interval (CI): 4.5-9.5] and 12 months (95% CI: 6.4-17.6), respectively (P=0.74); and the median overall survival (OS) was not reached in either group (P=0.93). Although patients receiving the combination therapy had a greater treatment response, no significant survival differences were observed between the lenvatinib monotherapy and combination therapy subgroups, even after inverse probability of treatment weighting (IPTW). Patients who received lenvatinib monotherapy could be stratified based on a combination of albumin-bilirubin (ALBI) grade (either grade 1 or 2a) and a neutrophil-lymphocyte ratio (NLR) of ≤5.8. Compared to the other subgroups combined, those who met both of these criteria exhibited PFS with a hazard ratio (HR) of 0.382 (95% CI: 0.168-0.871; P=0.02), corresponding to 11 and 5 months, respectively; and an OS (HR: 0.198, 95% CI: 0.043-0.920; P=0.04) of not reached versus 12 months, respectively, according to multivariate Cox regression analysis.ConclusionsIn our study cohort, there were no statistically significant differences observed in the survival rates between patients treated with lenvatinib monotherapy and those treated with a combination of lenvatinib and immunotherapy. The incorporation of ALBI grade and NLR facilitates the stratification of survival outcomes in patients with unresectable HCC undergoing lenvatinib monotherapy.

Project description:BackgroundLenvatinib is the first-line treatment for advanced hepatocellular carcinoma, but prognosis is still unsatisfactory. Recently, hepatic arterial infusion chemotherapy (HAIC), and immune checkpoint inhibitors showed promising results for advanced hepatocellular carcinoma. Considering different anti-malignancy mechanisms, combining these three treatments may improve outcomes. This study aimed to compare the efficacy and safety of lenvatinib, toripalimab, plus HAIC versus lenvatinib for advanced hepatocellular carcinoma.MethodsThis was a retrospective study including patients treated with lenvatinib [8 mg (⩽60 kg) or 12 mg (>60 kg) once daily] or lenvatinib, toripalimab plus HAIC [LeToHAIC group, lenvatinib 0-1 week prior to initial HAIC, 240 mg toripalimab 0-1 day prior to every HAIC cycle, and HAIC with FOLFOX regimen (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, 5-fluorouracil bolus 400 mg/m2 on day 1, and 5-fluorouracil infusion 2400 mg/m2 for 46 h, every 3 weeks)]. Progression-free survival, overall survival, objective response rate, and treatment-related adverse events were compared.ResultsFrom February 2019 to August 2019, 157 patients were included in this study: 71 in the LeToHAIC group and 86 in the lenvatinib group. The LeToHAIC group showed longer progression-free survival (11.1 versus 5.1 months, p < 0.001), longer overall survival (not reached versus 11 months, p < 0.001), and a higher objective response rate (RECIST: 59.2% versus 9.3%, p < 0.001; modified RECIST: 67.6% versus 16.3%, p < 0.001) than the lenvatinib group. In addition, 14.1% and 21.1% of patients in the LeToHAIC group achieved complete response of all lesions and complete response of the intrahepatic target lesions per modified RECIST criteria, respectively. Grade 3/4 treatment-related adverse events that were more frequent in the LeToHAIC group than in the lenvatinib group included neutropenia (8.5% versus 1.2%), thrombocytopenia (5.6% versus 0), and nausea (5.6% versus 0).ConclusionsLenvatinib, toripalimab, plus HAIC had acceptable toxic effects and might improve survival compared with lenvatinib alone in advanced hepatocellular carcinoma.
