Project description:We have previously conducted a phase I trial to test the efficacy of a glypican-3 (GPC3) peptide vaccine in patients with advanced hepatocellular carcinoma (HCC); however, its immunological mechanism of action remains unclear. Here, we report a pilot study conducted to evaluate the immunological mechanisms of action of this GPC3 peptide vaccine (UMIN-CTR number 000005093). Eleven patients with advanced HCC were vaccinated with the GPC3 peptide in this trial. The primary end point was GPC3 peptide-specific immune response induced by the GPC3 peptide vaccination. The secondary endpoints were clinical and biologic outcomes. We demonstrated that the present vaccine induced GPC3 peptide-specific cytotoxic T lymphocytes (CTLs), which were found to infiltrate into the tumor. Moreover, we established GPC3 peptide-specific CTL clones from a biopsy specimen: these cells exhibited GPC3 peptide-specific cytokine secretion and cell cytotoxicity. The plasma GPC3 level tended to decrease temporarily at least once during the follow-up period. The GPC3-specific CTL frequency after vaccination was correlated with overall survival. The degree of skin reactions at the injection site correlated with the GPC3 peptide-specific CTLs. Furthermore, we sequenced the T cell receptors (TCRs) of tumor-infiltrating lymphocyte (TIL) clones, and confirmed the existence of this TCR repertoire in both tumor tissue and PBMCs. In response to these data, we are developing TCR-engineered T cell therapy using TCR sequences obtained from GPC3 peptide-specific CTL clones for improved efficacy in patients with advanced HCC.

Project description:BACKGROUND: Molecularly targeted agents with anti-angiogenic activity, including bevacizumab, have demonstrated clinical activity in patients with advanced/metastatic hepatocellular carcinoma (HCC). This multicentre phase II study involving patients from several Asian countries sought to evaluate the safety and efficacy of bevacizumab plus capecitabine in this population. METHODS: Histologically proven/clinically diagnosed advanced HCC patients received bevacizumab 7.5 mg kg(-1) on day 1 and capecitabine 800 mg m(-2) twice daily on days 1-14 every 3 weeks as first-line therapy. RESULTS: A total of 45 patients were enrolled; 44 (96%) had extrahepatic metastasis and/or major vessel invasion and 30 (67%) had hepatitis B. No grade 3/4 haematological toxicity occurred. Treatment-related grade 3/4 non-haematological toxicities included diarrhoea (n=2, 4%), nausea/vomiting (n=1, 2%), gastrointestinal bleeding (n=4, 9%) and hand-foot syndrome (n=4, 9%). The overall response rate (RECIST) was 9% and the disease control rate was 52%. Overall, median progression-free survival (PFS) and overall survival (OS) were 2.7 and 5.9 months, respectively. Median PFS and OS were 3.6 and 8.2 months, respectively, for Cancer of the Liver Italian Programme (CLIP) score < or =3 patients, and 1.4 and 3.3 months, respectively, for CLIP score 4 patients. CONCLUSION: The bevacizumab-capecitabine combination shows good tolerability and modest anti-tumour activity in patients with advanced HCC.

Project description:BackgroundNo trials have compared cabozantinib and regorafenib for the second-line treatment of advanced hepatocellular carcinoma (HCC).ObjectivesConduct a matching-adjusted indirect comparison (MAIC) of the efficacy and safety of second-line cabozantinib and regorafenib in patients with advanced HCC and disease progression after prior sorafenib.MethodsThe CELESTIAL and RESORCE trials were used for indirect comparison of second-line cabozantinib and regorafenib in advanced HCC. Population-level data were available for RESORCE, individual patient data (IPD) for CELESTIAL. To align with RESORCE, the CELESTIAL population was limited to patients who received first-line sorafenib only. To minimize potential effect-modifying population differences, the CELESTIAL IPD were weighted to balance the distribution of clinically relevant baseline characteristics with those of RESORCE. Overall survival (OS) and progression-free survival (PFS) were evaluated for the matching-adjusted second-line CELESTIAL population and compared with those for RESORCE using weighted Kaplan-Meier curves and parametric modeling. Rates of grade 3/4 treatment-emergent adverse events (TEAEs) affecting > 5% of patients in any study arm were compared.ResultsIn the matching-adjusted second-line populations (CELESTIAL, effective sample size = 266; RESORCE, n = 573), median (95% confidence interval) OS was similar for cabozantinib and regorafenib (11.4 [8.9-17.0] versus 10.6 [9.1-12.1] months; p = 0.3474, log-rank test). Median PFS was longer for cabozantinib than regorafenib (5.6 [4.9-7.3] versus 3.1 [2.8-4.2] months; p = 0.0005, log-rank test). There was a trend for lower rates of some grade 3/4 TEAEs with regorafenib than with cabozantinib, which may reflect the exclusion of sorafenib-intolerant patients from RESORCE but not from CELESTIAL, a difference that the MAIC methods could not remove. Only diarrhea rates were statistically significantly lower for regorafenib (p ≤ 0.001).ConclusionsCabozantinib may achieve similar OS and prolonged PFS compared with regorafenib in patients with progressive advanced HCC after prior sorafenib.

Project description:Hepatocellular carcinoma (HCC) is a highly vascularized tumor in which neoangiogenesis contributes to growth and metastasis. We assessed the safety, efficacy, and potential biomarkers of activity of bevacizumab in patients with advanced HCC.In this phase II trial, eligible patients received bevacizumab, 5 mg/kg or 10 mg/kg every 2 weeks. The disease-control rate at 16 weeks (16W-DCR) was the primary endpoint. Circulating endothelial cells (CECs) and plasma cytokines and angiogenic factors (CAFs) were measured at baseline and throughout treatment.The 16W-DCR was 42% (95% confidence interval, 27%-57%). Six of the 43 patients who received bevacizumab achieved a partial response (objective response rate [ORR], 14%). Grade 3-4 asthenia, hemorrhage, and aminotransferase elevation occurred in five (12%), three (7%), and three (7%) patients, respectively. During treatment, placental growth factor markedly increased, whereas vascular endothelial growth factor (VEGF)-A dramatically decreased (p < .0001); soluble VEGF receptor-2 (p < .0001) and CECs (p = .03) transiently increased on day 3. High and increased CEC counts at day 15 were associated with the ORR (p = .04) and the 16W-DCR (p = .02), respectively. Lower interleukin (IL)-8 levels at baseline (p = .01) and throughout treatment (p ? .04) were associated with the 16W-DCR. High baseline IL-8 and IL-6 levels predicted shorter progression-free and overall survival times (p ? .04).Bevacizumab is active and well tolerated in patients with advanced HCC. The clinical value of CECs, IL-6, and IL-8 warrants further investigation.

Project description:BackgroundIt is still controversial whether hepatocellular carcinoma (HCC) patients with lymph node invasion should receive surgery treatment. This study aimed to evaluate the efficacy of surgery (liver resection and local tumor destruction treatments) in HCC patients with regional lymph node metastasis.MethodsThe study utilized data from the Surveillance, Epidemiology, and End Results-18 (SEER-18) cancer registry. Patients for whom the treatment type was not clear or those with distant metastasis or without regional lymph nodule invasion were excluded. For survival analysis, patients with the survival months coded as 0 and 999 were excluded. All 1434 patients were included in the analysis. Among them, 168 patients were treated surgically and the other 1266 received non-surgery therapy. Propensity score matching (PSM) model was used to reduce selection bias.ResultsBefore PSM, the median overall survival (mOS) and median cancer-specific survival (mCSS) of patients treated surgically were longer than that of receiving non-surgery treatment (mOS 20 months, 95% CI 15.3-24.7 vs. 7 months, 95% CI 6.4-7.6, P < 0.001; mCSS 21 months, 95% CI 115.5-26.5 vs. 6 months, 95% CI 5.3-6.7, P < 0.001). Subgroup analysis found no significant differences in mOS and mCSS between liver resection and non-liver resection surgery cohorts (P = 0.886 and P = 0.813, respectively). Similar results were obtained in the PSM analysis. The mOS and mCSS in the surgery group were longer than those in the non-surgery group (mOS 20 months vs. 7 months, P < 0.001; mCSS 20 months vs. 6 months, P < 0.001). The multivariate analysis documented that surgery was an independent predictor for OS and CSS before and after PSM.ConclusionsHCC patients with invasion of regional lymph nodules may get more survival benefit from surgery than other types of treatment.

Project description:Hepatocellular carcinoma (HCC) is the most common primary liver cancer with a dismal prognosis, especially when diagnosed at advanced stages. Surgical resection of the primary lesion, liver-directed therapies, and orthotropic liver transplantation are employed in localized disease depending upon the clinical status, underlying liver function, the size, and location of the liver lesions. Systemic therapy plays a critical role in the management of advanced HCC. Sorafenib had remained as the only United States Food and Drug Administration (US-FDA)-approved systemic therapeutic agent for approximately a decade since its approval in 2007, until the advent of immunotherapy and a better understanding of HCC molecular pathogenesis changed the landscape of advanced HCC management. Lenvatinib was approved as an alternative first-line agent, whereas regorafenib, nivolumab, pembrolizumab, ramucirumab, and cabozantinib were approved as second-line agents for HCC patients who could not tolerate or whose disease progressed on sorafenib. Nivolumab and pembrolizumab are the two immunotherapeutic agents that were conditionally approved by the US-FDA based on the encouraging results in Phase I/II trials. This review discusses the potential role of immunotherapy in advanced HCC with a special focus on nivolumab.

Project description:Sorafenib is a multikinase inhibitor approved for the treatment of advanced hepatocellular carcinoma (HCC). However, therapeutic response to sorafenib was not equal among HCC patients. Here we present a novel system to provide quantitative information concerning sorafenib-related targets by simultaneous detection of phosphorylated ERK (pERK) and pAkt expressions in circulating tumor cells (CTCs) isolated from HCC patients. Our results showed that 90.0% of patients had a molecular classification of tissues concordant with that of CTCs. CTC counts showed a shaper decline in patients with pERK+/pAkt- CTCs after two weeks of sorafenib treatment (P < 0.01). Disease control rates were significantly different between patients with pERK+/pAkt- CTCs (11/15; 73.3%) and those without (13/44; 29.5%) (P < 0.05). Univariate and multivariate analysis indicated pERK+/pAkt- CTCs as an independent predictive factor of progression-free survival (PFS) (hazard ratio = 9.389; P < 0.01). PFS correlated with the proportion of pERK+/pAkt- CTCs (r = 0.968, P < 0.01), and was higher in patients with ? 40% pERK+/pAkt- CTCs compared to those with < 40% (8.4 vs. 1.3 mo; P < 0.05). In a validation set of twenty HCC patients, CTCs from patients with ? 40% pERK+/pAkt- CTCs had significantly higher inhibition rates of spheroid formation compared to those with < 40% (61.2 vs. 19.8%; P < 0.01). Our findings demonstrated that CTCs can be used in place of tumor tissue for characterization of pERK/pAkt expression. pERK+/pAkt- CTCs are most sensitive to sorafenib and an independent predictive factor of PFS in HCC patients treated with sorafenib.

Project description:Many years after therapeutic wilderness, sorafenib finally showed a clinical benefit in patients with advanced hepatocellular carcinoma. After the primary general enthusiasm worldwide, some disappointments emerged particularly since no new treatment could exceed or at least match sorafenib in this setting. Without these new drugs, research focused on optimizing care of patients treated with sorafenib. One challenging research approach deals with identifying prognostic and predictive biomarkers of sorafenib in this population. The task still seems difficult; however appropriate investigations could resolve this dilemma, as observed for some malignancies where other drugs were used.

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:BackgroundCabozantinib inhibits tyrosine kinases, including vascular endothelial growth factor receptors 1, 2, and 3, MET, and AXL, which are implicated in the progression of hepatocellular carcinoma and the development of resistance to sorafenib, the standard initial treatment for advanced disease. This randomized, double-blind, phase 3 trial evaluated cabozantinib as compared with placebo in previously treated patients with advanced hepatocellular carcinoma.MethodsA total of 707 patients were randomly assigned in a 2:1 ratio to receive cabozantinib (60 mg once daily) or matching placebo. Eligible patients had received previous treatment with sorafenib, had disease progression after at least one systemic treatment for hepatocellular carcinoma, and may have received up to two previous systemic regimens for advanced hepatocellular carcinoma. The primary end point was overall survival. Secondary end points were progression-free survival and the objective response rate.ResultsAt the second planned interim analysis, the trial showed significantly longer overall survival with cabozantinib than with placebo. Median overall survival was 10.2 months with cabozantinib and 8.0 months with placebo (hazard ratio for death, 0.76; 95% confidence interval [CI], 0.63 to 0.92; P=0.005). Median progression-free survival was 5.2 months with cabozantinib and 1.9 months with placebo (hazard ratio for disease progression or death, 0.44; 95% CI, 0.36 to 0.52; P<0.001), and the objective response rates were 4% and less than 1%, respectively (P=0.009). Grade 3 or 4 adverse events occurred in 68% of patients in the cabozantinib group and in 36% in the placebo group. The most common high-grade events were palmar-plantar erythrodysesthesia (17% with cabozantinib vs. 0% with placebo), hypertension (16% vs. 2%), increased aspartate aminotransferase level (12% vs. 7%), fatigue (10% vs. 4%), and diarrhea (10% vs. 2%).ConclusionsAmong patients with previously treated advanced hepatocellular carcinoma, treatment with cabozantinib resulted in longer overall survival and progression-free survival than placebo. The rate of high-grade adverse events in the cabozantinib group was approximately twice that observed in the placebo group. (Funded by Exelixis; CELESTIAL ClinicalTrials.gov number, NCT01908426 .).
