559 Background: Immune checkpoint inhibitor (ICI) use in advanced hepatocellular carcinoma (HCC) is increasing. Real-world data on efficacy and safety however is lacking, more so when used in patients who fall out of standard clinical trial criteria. Methods: We conducted a retrospective review of all patients with advanced HCC seen at our centre who received at least one dose of an ICI between May 2015 - June 2018. Data cutoff was 31 Dec 2018. Responses were evaluated using RECIST v1.1 criteria. Results: 114 patients fulfilled inclusion criteria. Median age was 66 years and 88.6% were male. 96.5% had an ECOG PS of 0 – 1. 64.9% received an ICI within a clinical trial setting. 62.3% received monotherapy ICI. 19.6% of patients had Child-Pugh B disease on initiation of ICI, and 69.3% had an ALBI Grade of 2. 50.0% were known to have hepatitis B and 11.4% had hepatitis C. Baseline HBV VL ranged from undetectable to 8210000 IU/mL. 30.7% received prior systemic treatment, most commonly sorafenib (82.9%). Over a median follow-up duration of 5.7 months (0.03 - 42.4), ORR was 18.4%, and disease control rate (DCR) was 51.8%. Median PFS was 2.6 months (1.7 - 3.9), and median OS was 13.9 months (7.0 - 16.2). 5 patients (23.8%) had response duration of more than 18 months. 35.1% received further systemic therapy after ICI. On multivariable analyses, age ≥ 65 years, higher albumin level and lower bilirubin level were associated with increased OS. 68.0% of patients experienced adverse events (AEs) of any grade, 12.0% of these being grade 3 - 4. No grade 5 adverse events were observed. Use of antiviral therapy was associated with a lower risk of hepatic AEs (p = 0.04) whilst high baseline HBV VL was not associated with an increased risk of reactivation or hepatic AEs. Conclusions: In the real-world setting, responses and adverse event profiles to ICI use are comparable to those observed in clinical trials despite a more heterogenous population base. The expansion of indications for ICI use in advanced HCC beyond current approvals warrants greater study.

BackgroundProgrammed cell death protein 1 (PD-1) pathway blockade with immune checkpoint inhibitors (ICIs) is a standard therapy in advanced hepatocellular carcinoma (HCC) nowadays. No strategies to overcome ICI resistance have been described. We aimed to evaluate the use of ipilimumab and anti-PD-1 ICIs (nivolumab or pembrolizumab) combinations in patients with advanced HCC with progression on prior ICIs.MethodsPatients with advanced HCC with documented tumor progression on prior ICIs and subsequently received ipilimumab with nivolumab/pembrolizumab were analyzed. Objective response rate (ORR), median duration of response (DOR), time-to-progression (TTP), overall survival (OS), and treatment-related adverse events (TRAEs) were assessed.ResultsTwenty-five patients were included. The median age was 62 (range: 51–83). About 68% were of Child-Pugh (CP) Grade A and 48% had primary resistance to prior ICI. At median follow-up of 37.7 months, the ORR was 16% with a median DOR of 11.5 months (range: 2.76–30.3). Three patients achieved complete response. The median TTP was 2.96 months (95% CI: 1.61 to 4.31). Median OS was 10.9 months (95% CI: 3.99 to 17.8) and the 1 year, 2 year and 3 year survival rates were 42.4%, 32.3% and 21.6%, respectively. The ORR was 16.7% in primary resistance group and 15.4% in acquired resistance group (p=1.00). All responders were of CP A and Albumin-Bilirubin (ALBI) Grade 1 or 2. CP and ALBI Grades were significantly associated with OS (p=0.006 and p<0.001, respectively). Overall, 52% of patients experienced TRAEs and 12% experienced Grade 3 or above TRAEs.ConclusionsIpilimumab and nivolumab/pembrolizumab can achieve durable antitumor activity and encouraging survival outcomes with acceptable toxicity in patients with advanced HCC who had prior treatment with ICIs.

e16156 Background: Neutrophil to lymphocyte ratio (NLR) has been shown to associate with tumor progression. The present study was to investigate the role of NLR on predicting the treatment response for immune checkpoint inhibitors (ICIs) therapy in patients with advanced hepatocellular carcinoma (HCC). Methods: We retrospectively reviewed 81 patients received ICIs for advanced HCC from January 2017 to July 2019. We analyzed whether pre- and first 3 weeks post- treatment serum NLR level was associated with ICIs outcome. Results: In this study, the pre-treatment NLR level ranged from 0.64 to 14.93 among 81 patients. The cut-off level of NLR was set as the median value of 2.79. The objective response rate (ORR) in the patients with NLR<2.79 (low NLR) was 25.0%, which was significantly better than that of patients with NLR ≥2.79 (high NLR) (7.3%, P =0.03). Compared to patients with high NLR, patients with low NLR exhibited significantly longer median progression-free survival (PFS) (3.7 vs 3.0 months, P =0.004) and median overall survival (OS) (10.3 vs 7.5 months, P =0.001). Multivariate analysis revealed high NLR was an independent unfavourable prognostic factor for PFS (hazard ratio [HR] = 1.857, 95% confidence interval [CI] = 1.093-3.154; P = 0.022) and OS (HR = 2.267, 95% CI = 1.221-4.207; P = 0.009). For the patients with high pre-treatment NLR level, ICIs outcome was stratified more clearly by first 3 weeks post- treatment NLR level. Conclusions: The pre- and first 3 weeks post- treatment serum NLR level could be considered as a predictive factor of treatment response for ICIs in patients with advanced HCC.

In advanced-stage hepatocellular carcinoma (HCC), systemic treatment represents the standard therapy. Target therapy has marked a new era based on a greater knowledge of molecular disease signaling. Nonetheless, survival outcomes and long-term response remain unsatisfactory, mostly because of the onset of primary or acquired resistance. More recently, results from clinical trials with immune targeting agents, such as the immune checkpoint inhibitors (ICIs), have shown a promising role for these drugs in the treatment of advanced HCC. In the context of an intrinsic tolerogenic liver environment, since HCC-induced immune tolerance, it is supported by multiple immunosuppressive mechanisms and several clinical trials are now underway to evaluate ICI-based combinations, including their associations with antiangiogenic agents or multikinase kinase inhibitors and multiple ICIs combinations. In this review, we will first discuss the basic principles of hepatic immunogenic tolerance and the evasive mechanism of antitumor immunity in HCC; furthermore we will elucidate the consistent biological rationale for immunotherapy in HCC even in the presence of an intrinsic tolerogenic environment. Subsequently, we will critically report and discuss current literature on ICIs in the treatment of advanced HCC, including a focus on the currently explored combinatorial strategies and their rationales. Finally, we will consider both challenges and future directions in this field.

Introduction/Objective: Lenvatinib demonstrated efficacy and safety in patients with advanced hepatocellular carcinoma (HCC) in the randomized phase III REFLECT trial. Considering the discrepancies in patients between clinical trial data and daily practice, an account of practical experience is needed. Methods: We conducted a multicenter retrospective analysis in which 3 tertiary referral centers participated. A total of 92 patients with advanced HCC treated with lenvatinib between September 2018 and January 2020 were analyzed. Results: Lenvatinib was used as the first-line therapy for 67 (72.8%) patients, and for 25 (27.2%) patients previously treated with other systemic therapy including immune checkpoint inhibitors. At the time of initiation of lenvatinib, 74 (80.4%) and 18 (19.6%) patients were classified as Child-Pugh A and B, respectively. Thirty-five patients (38.0%) had extensive disease that would have excluded them from the REFLECT trial. In the Child-Pugh A group, the response rate graded according to the Response Evaluation Criteria in Solid Tumors v1.1 was 21.1%, median progression-free survival (PFS) was 4.6 (95% confidence interval [CI] 3.1–6.1) months, and overall survival (OS) was 10.7 (95% CI 4.8–16.5) months for patients treated with first-line lenvatinib (n = 57). With second- or later-line lenvatinib (n = 17), median PFS and OS were 4.1 (95% CI 3.1–5.1) and 6.4 (95% CI 5.1–7.7) months, respectively. In the Child-Pugh B group (n = 18), median PFS and OS were 2.6 (95% CI 0.6–4.6) and 5.3 (95% CI 2.0–8.5) months, respectively. The most common grade 3–4 toxicities were hyperbilirubinemia (n = 8; 8.7%), AST elevation (n = 6; 6.5%), and diarrhea (n = 5; 5.4%) across all study patients. Conclusions: In this real-world study, lenvatinib was found to be well tolerated and effective in more heterogeneous HCC patient populations.

Abstract BackgroundThe survival benefit and safety of transarterial chemoembolization (TACE) for advanced Hepatocellular Carcinoma (HCC) patients treated with tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) is unclear. We aimed to investigate the efficacy and safety of TACE combined with TKIs and ICIs the treatment of advanced HCC. MethodsIn this study, the conditions of 147 patients with advanced HCC who underwent TKIs plus ICIs treatment between July 2017 and April 2020 were evaluated. We divided these patients into the TACE group and non-TACE group based on whether they were treated with TACE during TKIs plus ICIs treatment, and compared their survival outcomes, especially overall survival (OS), and whether they were exposed to unexpected toxicities. ResultsIn this study, a total of 98 patients who underwent TACE during TKIs plus ICIs treatment were included in the TACE group, while the other 49 patients were included in the non-TACE group. According to the Modified Response Evaluation Criteria in Solid Tumors (mRECIST), the objective response rate (ORR) of the TACE group was higher than that of the non-TACE group (ORR 74.5% vs. 40.8%, p <0.001). The OS of the TACE group was significantly longer than the non-TACE group (OS 19.3 months vs. 10.8 months, p = 0.010). The incidence of grade 3-4 toxicities in the TACE group was similar to that in the non-TACE group (33.7% vs. 28.6%, p = 0.532). ConclusionsThe TACE treatment combined with TKIs plus ICIs resulted in longer OS compared to the treatment of systemic TKIs plus ICIs without TACE during the process of advanced HCC.

Review question / Objective: Is immunotherapy associated with beneficial clinical outcomes for hepatocellular carcinoma (HCC) and how can combination immunotherapy be deployed to produce the best benefit? Is tumor mutation burden (TMB) a predictive biomarker for immune‐checkpoint inhibitors? Condition being studied: To this date, about 50 single-arm clinical trials and several randomized control trials (RCTs) presented final or interim results of investigations on the efficacy of PD-1/PD-L1 inhibitors for advanced HCC. In the CheckMate 459, IMbrave 050, and ORIENT-32, immunotherapies were found to significantly improve progression-free survival (PFS) and overall survival (OS) compared with sorafenib (a tyrosine-kinase inhibitor, as standard systemic treatment) in patients with advanced hepatocellular carcinoma. However, these clinical trials were different on clinical phases, sample size, and response evaluation criteria, and inconsistent clinical outcomes were shown in several trials.

With the development of molecular targeting therapy, several treatment options for advanced hepatocellular carcinoma (HCC) have become available in cases where curative and other palliative treatments, such as radiofrequency ablation, surgical resection, and transarterial chemoembolization, are not applicable. However, with the detection of a variety of mutations in cancer-related genes in a single tumor, molecular heterogeneity is commonly observed in HCC. Therefore, mutations in the major cellular signaling pathways underlie the development of resistance to molecular targeting agents. On the contrary, immune checkpoint inhibitors have proven effective in patients who are refractory to conventional treatments and molecular targeting therapy. Several clinical trials are currently investigating the efficacy of immune checkpoint inhibitors both individually and in combination with other types of anticancer agents. In this review, we focus on the potential of immune checkpoint blockade in the treatment of human HCC.
