Randomised, multicentre prospective trial of transarterial chemoembolisation (TACE) plus sorafenib as compared with TACE alone in patients with hepatocellular carcinoma: TACTICS trial.

OBJECTIVE:This trial compared the efficacy and safety of transarterial chemoembolisation (TACE) plus sorafenib with TACE alone using a newly established TACE-specific endpoint and pre-treatment of sorafenib before initial TACE. DESIGN:Patients with unresectable hepatocellular carcinoma (HCC) were randomised to TACE plus sorafenib (n=80) or TACE alone (n=76). Patients in the combination group received sorafenib 400 mg once daily for 2-3 weeks before TACE, followed by 800 mg once daily during on-demand conventional TACE sessions until time to untreatable (unTACEable) progression (TTUP), defined as untreatable tumour progression, transient deterioration to Child-Pugh C or appearance of vascular invasion/extrahepatic spread. Co-primary endpoints were progression-free survival (PFS), which is not a conventional one but defined as TTUP, or time to any cause of death plus overall survival (OS). Multiplicity was adjusted by gatekeeping hierarchical testing. RESULTS:Median PFS was significantly longer in the TACE plus sorafenib than in the TACE alone group (25.2 vs 13.5 months; p=0.006). OS was not analysed because only 73.6% of OS events were reached. Median TTUP (26.7 vs 20.6 months; p=0.02) was also significantly longer in the TACE plus sorafenib group. OS at 1 year and 2 years in TACE plus sorafenib group and TACE alone group were 96.2% and 82.7% and 77.2% and 64.6%, respectively. There were no unexpected toxicities. CONCLUSION:TACE plus sorafenib significantly improved PFS over TACE alone in patients with unresectable HCC. Adverse events were consistent with those of previous TACE combination trials.

Ramucirumab in the second-line for patients with hepatocellular carcinoma and elevated alpha-fetoprotein: patient-reported outcomes across two randomised clinical trials

Background: Symptoms of advanced hepatocellular carcinoma (HCC) represent a substantial burden for the patient and are important endpoints to assess when evaluating treatment. Patient-reported outcomes were evaluated in subjects with advanced HCC and baseline alpha-fetoprotein (AFP) ≥400 ng/mL treated with second-line ramucirumab. Patients and methods: Patients with AFP≥400 ng/mL enrolled in the REACH or REACH-2 phase 3 studies were used in this analysis. Eligible patients had advanced HCC, Child-Pugh A, Eastern Cooperative Oncology Group performance status 0/1 and prior sorafenib. Patients received ramucirumab 8 mg/kg or placebo once every 2 weeks. Disease-related symptoms and health-related quality of life (HRQoL) were assessed with the Functional Assessment of Cancer Therapy Hepatobiliary Symptom Index (FHSI)-8 and EuroQoL-5-Dimensions (EQ-5D) instruments, respectively. Time to deterioration (TTD) (≥3-point decrease in FHSI-8 total score;≥0.06-point decrease in EQ-5D score, from randomisation to first date of deterioration) was determined using Kaplan-Meier estimation and the Cox proportional hazards model. Both separate and pooled analyses for REACH AFP≥400 ng/mL and REACH-2 patients were conducted. Results: In the pooled population with AFP ≥400 ng/mL (n=542; ramucirumab, n=316; placebo, n=226), median TTD in FHSI-8 total score was prolonged with ramucirumab relative to placebo (3.3 vs 1.9 months; HR 0.725; (95% CI 0.559 to 0.941); p=0.0152), including significant differences in back pain (0.668; (0.497 to 0.899); p=0.0044), weight loss (0.699; (0.505 to 0.969); p=0.0231) and pain (0.769; (0.588 to 1.005); p=0.0248) symptoms. TTD in EQ-5D score was not significantly different between ramucirumab and placebo groups (median 2.9 vs 1.9 months). Results in the individual trials were consistent with these findings. Conclusions: Ramucirumab in second-line treatment of advanced HCC demonstrates consistent benefit in the delay of deterioration in disease-related symptoms with no worsening of HRQoL. Taken with previously demonstrated ramucirumab-driven survival benefits in this setting, these data may inform patient-clinician discussions about the benefit-risk profile of this therapy

Second-line ramucirumab therapy for advanced hepatocellular carcinoma (REACH): an East Asian and non-East Asian subgroup analysis

Purpose REACH investigated second-line ramucirumab therapy for advanced hepatocellular carcinoma. Results: Median overall survival was 8.2 months for ramucirumab and 6.9 months for placebo (HR, 0.835; 95% CI, 0.634–1.100; p = 0.2046) for East Asians, and 10.1 months for ramucirumab and 8.0 months for placebo (HR, 0.895; 95% CI, 0.690–1.161; p = 0.4023) for non-East Asians. Median overall survival in patients with baseline alpha-fetoprotein ≥ 400 ng/mL was 7.8 months for ramucirumab and 4.2 months for placebo (HR, 0.749; 95% CI, 0.519–1.082; p = 0.1213) for East Asians (n = 139), and 8.2 months for ramucirumab and 4.5 months for placebo (HR, 0.579; 95% CI, 0.371–0.904; p = 0.0149) for non-East Asians (n = 111). The most common grade ≥ 3 treatment-emergent adverse events in East Asians and non-East Asians included hypertension and malignant neoplasm progression. Materials and methods A post-hoc analysis of East Asians (N = 252) and non-East Asians (N = 313) in the intent-to-treat population was performed. Conclusions: In East Asians and non-East Asians, ramucirumab did not significantly prolong overall survival. In patients with baseline alpha-fetoprotein ≥ 400 ng/mL, a potentially larger survival benefit was observed in both subgroups. Safety for East Asians was similar to non-East Asians

Phase Ib Study of Lenvatinib Plus Pembrolizumab in Patients With Unresectable Hepatocellular Carcinoma

PURPOSE The immunomodulatory effect of lenvatinib (a multikinase inhibitor) on tumor microenvironments may contribute to antitumor activity when combined with programmed death receptor-1 (PD-1) signaling inhibitors in hepatocellular carcinoma (HCC). We report results from a phase Ib study of lenvatinib plus pembrolizumab (an anti-PD-1 antibody) in unresectable HCC (uHCC). PATIENTS AND METHODS In this open-label multicenter study, patients with uHCC received lenvatinib (bodyweight $60 kg, 12 mg; , 60 kg, 8 mg) orally daily and pembrolizumab 200 mg intravenously on day 1 of a 21- day cycle. The study included a dose-limiting toxicity (DLT) phase and an expansion phase (first-line patients). Primary objectives were safety/tolerability (DLT phase), and objective response rate (ORR) and duration of response (DOR) by modified RECIST (mRECIST) and RECIST version 1.1 (v1.1) per independent imaging review (IIR; expansion phase). RESULTS A total of 104 patients were enrolled. No DLTs were reported (n 5 6) in the DLT phase; 100 patients (expansion phase; included n 5 2 from DLT phase) had received no prior systemic therapy and had Barcelona Clinic Liver Cancer stage B (n 5 29) or C disease (n 5 71). At data cutoff, 37$ 3 treatment-related adverse events occurred in 67% (grade 5, 3%) of patients. No new safety signals were identified. CONCLUSION Lenvatinib plus pembrolizumab has promising antitumor activity in uHCC. Toxicities were manageable, with no unexpected safety signals

Alpha-fetoprotein kinetics in patients with hepatocellular carcinoma receiving ramucirumab or placebo: An analysis of the phase 3 REACH study

Background: Post-hoc analyses of AFP response and progression and their relationship with objective measures of response and survival were performed in patients from REACH. Methods: Serum AFP was measured at baseline and every 3 cycles (2 weeks/cycle). Associations between AFP and radiographic progression and efficacy end points were analysed. Results: Median percent AFP increase from baseline was smaller in the ramucirumab than in the placebo arm throughout treatment. Time to AFP progression (HR 0.621; P < 0.0001) and to radiographic progression (HR 0.613; P < 0.0001) favoured ramucirumab. Association between AFP and radiographic progression was shown at 6 (OR 6.44, 95% CI 4.03, 10.29; P < 0.0001) and 12 weeks (OR 2.28, 95% CI 1.47, 3.53; P = 0.0002). AFP response was higher with ramucirumab compared with placebo (P < 0.0001). More patients in the ramucirumab arm experienced tumour shrinkage and AFP response compared with placebo. Survival was longer in patients with AFP response (13.6 months) than in patients without (6.2 months), irrespective of treatment (HR 0.457, P < 0.0001). Conclusions: Treatment with ramucirumab prolonged time to AFP progression, slowed AFP increase and was more likely to induce AFP response. Similar benefits in radiographic progression and response correlated with AFP changes

Ramucirumab in elderly patients with hepatocellular carcinoma and elevated alpha-fetoprotein after sorafenib in REACH and REACH-2

Background & Aims: Limited data on treatment of elderly patients with hepatocellular carcinoma (HCC) increase the unmet need. REACH and REACH‐2 were global phase III studies of ramucirumab in patients with HCC after prior sorafenib, where patients with alpha‐fetoprotein (AFP) ≥400 ng/mL showed an overall ssurvival (OS) benefit for ramucirumab. These post‐hoc analyses examined efficacy and safety of ramucirumab in patients with HCC and baseline AFP ≥ 400 ng/mL by three prespecified age subgroups (<65, ≥65 to <75 and ≥75 years). Methods: Individual patient data were pooled from REACH (baseline AFP ≥400 ng/mL) and REACH‐2. Kaplan‐Meier and Cox proportional hazards regression methods (stratified by study) assessed OS, progression‐free survival (PFS), time to progression (TTP) and patient‐reported outcomes (Functional Hepatobiliary System Index‐8 [FHSI‐8] score). Results: A total of 542 patients (<65 years: n = 302; ≥65 to <75 years: n = 160; ≥75 years: n = 80) showed similar baseline characteristics between ramucirumab and placebo. Older subgroups had higher hepatitis C and steatohepatitis incidences, and lower AFP levels, than the <65 years subgroup. Ramucirumab prolonged OS in patients <65 years (hazard ratio [HR], 0.753; 95% CI 0.581‐0.975), ≥65 to <75 years (0.602; 0.419‐0.866) and ≥75 years (0.709; 0.420‐1.199), PFS and TTP irrespective of age. Ramucirumab showed similar overall safety profiles across subgroups, with a consistent median relative dose intensity ≥97.8%. A trend towards a delay in symptom deterioration in FHSI‐8 with ramucirumab was observed in all subgroups. Conclusions: In this post‐hoc analysis, ramucirumab showed a survival benefit across age subgroups with a tolerable safety profile, supporting its use in advanced HCC with elevated AFP, irrespective of age, including ≥75 years

Real Life Study of Lenvatinib Therapy for Hepatocellular Carcinoma: RELEVANT Study

Introduction: In the REFLECT trial, lenvatinib was found to be noninferior compared to sorafenib in terms of overall survival. Here, we analyze the effects of lenvatinib in the real-life experience of several centers across the world and identify clinical factors that could be significantly associated with survival outcomes. Methods: The study population was derived from retrospectively collected data of HCC patients treated with lenvatinib. The overall cohort included western and eastern populations from 23 center in five countries. Results: We included 1,325 patients with HCC and treated with lenvatinib in our analysis. Median OS was 16.1 months. Overall response rate was 38.5%. Multivariate analysis for OS highlighted that HBsAg positive, NLR &gt;3, and AST &gt;38 were independently associated with poor prognosis in all models. Conversely, NAFLD/NASH-related etiology was independently associated with good prognosis. Median progression-free survival was 6.3 months. Multivariate analysis for progression-free survival revealed that NAFLD/NASH, BCLC, NLR, and AST were independent prognostic factors for progression-free survival. A proportion of 75.2% of patients suffered from at least one adverse effect during the study period. Multivariate analysis exhibited the appearance of decreased appetite grade ≥2 versus grade 0-1 as an independent prognostic factor for worse progression-free survival. 924 patients of 1,325 progressed during lenvatinib (69.7%), and 827 of them had a follow-up over 2 months from the beginning of second-line treatment. From first-line therapy, the longest median OS was obtained with the sequence lenvatinib and immunotherapy (47.0 months), followed by TACE (24.7 months), ramucirumab (21.2 months), sorafenib (15.7 months), regorafenib (12.7 months), and best supportive care (10.8 months). Conclusions: Our study confirms in a large and global population of patients with advanced HCC, not candidates for locoregional treatment the OS reported in the registration study and a high response rate with lenvatinib

Final Results of TACTICS: A Randomized, Prospective Trial Comparing Transarterial Chemoembolization Plus Sorafenib to Transarteria Chemoembolization Alone in Patients with Unresectable Hepatocellular Carcinoma

IntroductionSeveral clinical trials comparing the efficacy and safety of transarterial chemoembolization (TACE) plus molecular-targeted agents versus TACE alone revealed no clinical benefits in progression-free survival (PFS) or overall survival (OS). Here, we report the final OS analysis from the TACTICS trial, which previously demonstrated significant improvement in PFS with TACE plus sorafenib in patients with unresectable hepatocellular carcinoma (HCC) (NCT01217034).MethodsPatients with unresectable HCC were randomized to a TACE plus sorafenib group (N = 80) or a TACE alone group (N = 76). Patients in the combination treatment group received sorafenib 400 mg once daily for 2-3 weeks before TACE, followed by 800 mg once daily during on-demand conventional TACE sessions until time to untreatable progression. In this trial, TACE-specific PFS was used. TACE-specific PFS is defined as the time from randomization to progressive disease (PD) or death from any cause, and PD was defined as untreatable progression, caused by the inability of a patient to further receive or benefit from TACE for reasons that include intrahepatic tumor progression (25% increase vs. baseline) according to response evaluation criteria in cancer of the liver, the detection of extrahepatic spread, vascular invasion, or transient deterioration of liver function to Child-Pugh C after TACE.ResultsAt the cut-off date of July 31, 2020, 131 OS events were observed. The median OS was 36.2 months with TACE plus sorafenib and 30.8 months with TACE alone (hazard ratio [HR] = 0.861; 95% confidence interval [CI], 0.607-1.223; p = 0.40, ΔOS, 5.4 months). The updated PFS was 22.8 months with TACE plus sorafenib and 13.5 months with TACE alone (HR = 0.661; 95% CI, 0.466-0.938; p = 0.02). Post-trial treatments with active procedures/agents were received by 47 (58.8%) patients in the TACE plus sorafenib group and 58 (76.3%) in the TACE alone group (p = 0.01). In post hoc analysis, PFS and OS benefit were shown in HCC patients with tumor burden beyond up-to-7 criteria.ConclusionsIn TACTICS trial, TACE plus sorafenib did not show significant OS benefit over TACE alone; however, clinical meaningful OS prolongation and significantly improved PFS was observed. Thus, the TACE plus sorafenib can be considered a choice of treatment in intermediate-stage HCC, especially in patients with high tumor burden. Trial Registration: NCT01217034

Sorafenib plus low-dose cisplatin and fluorouracil hepatic arterial infusion chemotherapy versus sorafenib alone in patients with advanced hepatocellular carcinoma (SILIUS): a randomised, open label, phase 3 trial

Background Hepatic arterial infusion chemotherapy plus sorafenib in phase 2 trials has shown favourable tumour control and a manageable safety profile in patients with advanced, unresectable hepatocellular carcinoma. However, no randomised phase 3 trial has tested the combination of sorafenib with continuous arterial infusion chemotherapy. We aimed to compare continuous hepatic arterial infusion chemotherapy plus sorafenib with sorafenib alone in patients with advanced, unresectable hepatocellular carcinoma. Methods We did an open-label, randomised, phase 3 trial (SILIUS) at 31 sites in Japan. Eligible patients were aged 20 years or older, with advanced hepatocellular carcinoma not suitable for resection, local ablation, or transarterial chemoembolisation; Eastern Cooperative Oncology Group (ECOG) performance status 0–1; Child-Pugh score 7 or lower; and adequate bone marrow, liver, and renal function. Patients were randomly assigned (1:1) via an interactive web response system with a computer-generated sequence to receive 400 mg sorafenib orally twice daily or 400 mg sorafenib orally twice daily plus hepatic arterial infusion chemotherapy (cisplatin 20 mg/m 2 on days 1 and 8 and fluorouracil 330 mg/m 2 continuously on days 1–5 and 8–12 of every 28-day cycle via an implanted catheter system). The primary endpoint was overall survival. The primary efficacy analysis comprised all randomised patients (the intention-to-treat population), and the safety analysis comprised all randomised patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov, number NCT01214343. Findings Between Nov 4, 2010, and June 10, 2014, 206 patients were randomly assigned (103 to the sorafenib group, 103 to the sorafenib plus hepatic arterial infusion chemotherapy group). One patient in the sorafenib plus hepatic arterial infusion chemotherapy group withdrew after randomisation. Median overall survival was similar in the sorafenib plus hepatic arterial infusion chemotherapy (n=102) and sorafenib monotherapy (n=103) groups (11·8 months [95% CI 9·1–14·5] vs 11·5 months [8·2–14·8]; hazard ratio 1·009 [95% CI 0·743–1·371]; p=0·955). Grade 3–4 adverse events that were more frequent in the sorafenib plus hepatic arterial infusion chemotherapy group than in the sorafenib monotherapy group included anaemia (15 [17%] of 88 vs six [6%] of 102), neutropenia (15 [17%] vs one [1%]), thrombocytopenia (30 [34%] vs 12 [12%]), and anorexia (12 [14%] vs six [6%]). Interpretation Addition of hepatic arterial infusion chemotherapy to sorafenib did not significantly improve overall survival in patients with advanced hepatocellular carcinoma.
