Phase II study of bevacizumab and erlotinib in the treatment of advanced hepatocellular carcinoma patients with sorafenib-refractory disease.

ABSTRACT: The combination of bevacizumab (B) and erlotinib (E) has shown promising clinical outcomes as the first-line treatment of advanced HCC patients. We aimed to evaluate the efficacy and safety of using combination of B?+?E in treating advanced HCC patients who had failed prior sorafenib treatment.Eligible advanced HCC patients with documented radiological evidence of disease progression with sorafenib treatment were recruited. All patients received bevacizumab(B) at 10 mg/kg every 2 weeks with erlotinib(E) at 150 mg daily for a maximum of 6 cycles. Response assessments using both RECIST and modified RECIST criteria were performed after every 6 weeks. The primary endpoint was clinical benefit (CB) rate and a Simon two-stage design was employed.The trial was halted in the first stage according to the pre-set statistical criteria with 10 patients recruited. The median age was 47 years (range, 28-61) and all patients were in ECOG performance status 1. Eighty percent of patients were chronic hepatitis B carriers and all patients had Child A cirrhosis. Among these 10 patients, none of the enrolled patients achieved response or stable disease. The median time-to-progression was 1.81 months (95 % confidence interval [C.I.], 1.08-1.74 months) and overall survival was 4.37 months (95 % C.I., 1.08-11.66 months). Rash (70 %), diarrhea (50 %) and malaise (40 %) were the most commonly encountered toxicities.The combination of B?+?E was well tolerated but had no activity in an unselected sorafenib-refractory advanced HCC population. Condensed abstract The combination of bevacizumab and erlotinib had no clinical activity in sorafenib-refractory HCC population.

Project description:BackgroundHepatocellular carcinoma (HCC) is a common cancer associated with a poor prognosis. Bevacizumab is a monoclonal antibody that binds vascular endothelial growth factor, a mediator of tumor angiogenesis. Bevacizumab is currently under investigation as treatment for HCC. We performed a systematic review of the efficacy and safety of bevacizumab for the treatment of advanced HCC.MethodsPubMed, the Cochrane Library, and Google Scholar were searched using the terms "bevacizumab AND hepatocellular carcinoma AND (advanced OR unresectable)". Phase II trials of bevacizumab for the treatment of advanced HCC were included. Outcomes of interest included progression-free and overall survival (PFS and OS), tumor response, and toxicities.ResultsA total of 26 records were identified. Of these, 18 were excluded. Hence, eight trials involving 300 patients were included. Bevacizumab was given as monotherapy (n = 1 trial) or in combination with erlotinib (n = 4 trials), capecitabine (n = 1 trial), capecitabine+oxaliplatin (n = 1 trial), or gemcitabine+oxaliplatin (n = 1 trial). Most trials (five of eight) reported median PFS and OS between 5.3 months and 9.0 months and 5.9 and 13.7 months, respectively. The disease control rate was consistent in five of eight trials, ranging from 51.1% to 76.9%. The response and partial response rates ranged from 0 to 23.7%, but were around 20% in four trials. Only one patient had a complete response. Frequently reported Grade 3/4 toxicities were increased aspartate transaminase/alanine transaminase (13%), fatigue (12%), hypertension (10%), diarrhea (8%), and neutropenia (5%). Thirty patients experienced gastrointestinal bleeding (grade 1/2 = 18, grade 3/4 = 12), typically due to esophageal varices.ConclusionsBevacizumab shows promise as an effective and tolerable treatment for advanced HCC. The reported efficacy of bevacizumab appears to compare favorably with that of sorafenib, the only currently approved treatment for unresectable HCC. Phase III trials are warranted to comprehensively examine the efficacy and safety of bevacizumab for treatment of advanced HCC.

Project description:Lessons learnedTrebananib leveraging anti-angiogenic mechanism that is distinct from the classic sorafenib anti-vascular endothelial growth factor inhibition did not demonstrate improved progression-free survival at 4 months in patients with advanced hepatocellular carcinoma (HCC).In support of previously reported high Ang-2 levels' association with poor outcome in HCC for patients, trebananib treatment with lower baseline Ang-2 at study entry was associated with improved overall survival to 22 months and may suggest future studies to be performed within the context of low baseline Ang-2.BackgroundAng-1 and Ang-2 are angiopoietins thought to promote neovascularization via activation of the Tie-2 angiopoietin receptor. Trebananib sequesters Ang-1 and Ang-2, preventing interaction with the Tie-2 receptor. Trebananib plus sorafenib combination has acceptable toxicity. Elevated Ang-2 levels are associated with poor prognosis in hepatocellular carcinoma (HCC).MethodsPatients with HCC, Eastern Cooperative Oncology Group ≤2, and Childs-Pugh A received IV trebananib at 10 mg/kg or 15 mg/kg weekly plus sorafenib 400 mg orally twice daily. The study was planned for ≥78% progression-free survival (PFS) rate at 4 months relative to 62% for sorafenib historical control (power = 80% α = 0.20). Secondary endpoints included safety, tolerability, overall survival (OS), and multiple biomarkers, including serum Ang-2.ResultsThirty patients were enrolled sequentially in each of the two nonrandomized cohorts. Demographics were comparable between the two arms and the historical controls. PFS rates at 4 months were 57% and 54% on the 10 mg/kg and 15 mg/kg trebananib cohorts, respectively. Median OS was 17 and 11 months, respectively. Grade 3 and above events noted in ≥10% of patients included fatigue, hypertension, diarrhea, liver failure, palmar-plantar erythrodysesthesia syndrome, dyspnea, and hypophosphatemia. One death was due to hepatic failure. Serum Ang-2 dichotomized at the median was associated with improved OS in both cohorts.ConclusionThere was no improvement in PFS rate at 4 months in either cohort, when compared with sorafenib historical control.

Project description:Background and objectiveHepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death worldwide, especially in China. According to the 2021 Chinese Society of Clinical Oncology guidelines, sorafenib, lenvatinib, atezolizumab combined with bevacizumab, and sintilimab combined with bevacizumab are recommended as first-line treatment options for advanced HCC. This study provides a cost-effectiveness analysis of these treatments from the patient perspective.MethodsA partitioned survival model was established using the TreeAge 2019 software to evaluate the cost-effectiveness. The model includes three states, namely progression-free survival, progressive disease, and death. Clinical data were derived from three randomized controlled studies involving patients with advanced HCC who received the following treatment: sorafenib and lenvatinib (NCT01761266); atezolizumab in combination with bevacizumab (NCT03434379); and sintilimab in combination with bevacizumab (NCT03794440). Cost and clinical preference data were obtained from the literature and interviews with clinicians.ResultsAll compared with sorafenib therapy, lenvatinib had an incremental cost-effectiveness ratio (ICER) of US$188,625.25 per quality-adjusted life year (QALY) gained; sintilimab plus bevacizumab had an ICER of US$75,150.32 per QALY gained; and atezolizumab plus bevacizumab had an ICER of US$144,513.71 per QALY gained. The probabilistic sensitivity analysis indicated that treatment with sorafenib achieved a 100% probability of cost-effectiveness at a threshold of US$36,600/QALY. One-way sensitivity analysis revealed that the results were most sensitive to the medical insurance reimbursement ratio and drug prices.ConclusionsIn this economic evaluation, therapy with lenvatinib, sintilimab plus bevacizumab, and atezolizumab plus bevacizumab generated incremental QALYs compared with sorafenib; however, these regimens were not cost-effective at a willingness-to-pay threshold of US$36,600 per QALY. Therefore, some patients may achieve preferred economic outcomes from these three therapies by tailoring the regimen based on individual patient factors.
