Immunomodulatory activity of lenvatinib contributes to antitumor activity in the Hepa1-6 hepatocellular carcinoma model.

ABSTRACT: Angiogenesis inhibitors such as lenvatinib and sorafenib, and an immune checkpoint inhibitor (ICI), nivolumab, are used for anticancer therapies against advanced hepatocellular carcinoma (HCC). Combination treatments comprising angiogenesis inhibitors plus ICIs are promising options for improving clinical benefits in HCC patients, and clinical trials are ongoing. Here, we investigated the antitumor and immunomodulatory activities of lenvatinib (a multiple receptor tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor 1-3, fibroblast growth factor receptor 1-4, platelet-derived growth factor receptor ?, KIT and RET) and the combined antitumor activity of lenvatinib plus anti-programmed cell death 1 (PD-1) antibody in the Hepa1-6 mouse HCC syngeneic model. We found that the antitumor activities of lenvatinib and sorafenib were not different in immunodeficient mice, but lenvatinib showed more potent antitumor activity than sorafenib in immunocompetent mice. The antitumor activity of lenvatinib was greater in immunocompetent mice than in immunodeficient mice and was attenuated by CD8+ T cell depletion. Treatment with lenvatinib plus anti-PD-1 antibody resulted in more tumor regression and a higher response rate compared with either treatment alone in immunocompetent mice. Single-cell RNA sequencing analysis demonstrated that treatment with lenvatinib with or without anti-PD-1 antibody decreased the proportion of monocytes and macrophages population and increased that of CD8+ T cell populations. These data suggest that lenvatinib has immunomodulatory activity that contributes to the antitumor activity of lenvatinib and enhances the antitumor activity in combination treatment with anti-PD-1 antibody. Combination treatment of lenvatinib plus anti-PD-1 antibody therefore warrants further investigation against advanced HCC.

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: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.
