First-line targ veted therapies of advanced hepatocellular carcinoma: A Bayesian network analysis of randomized controlled trials.

ABSTRACT: PURPOSE:A variety of targeted drug were developed and proved effective and safe in clinical trials. Our study aims to compare the efficacies and safety of different targeted drugs in advanced hepatocellular carcinoma (HCC) for first-line treatment using a Bayesian network meta-analysis approach. METHODS:PubMed, Embase, and Cochrane library were searched for randomized controlled trials (RCTs) of advanced HCC patients that treated with different targeted drugs. Time to progress (TTP), overall survival (OS) and progress-free survival (PFS) were calculated as hazard ratios (HRs). Objective response rate (ORR) and the proportion of Grade 3-5 adverse events (G3-5AE) were expressed as odds ratios (ORs). We pooled study-specific HRs and ORs using Bayesian network meta-analyses, and ranked first-line drugs by the surface under the cumulative ranking curve (SUCRA). RESULTS:A total of 22 RCTs with 9288 patients were enrolled. Brivanib, linifanib, lenvatinib and sorafenib showed a significant improvement on TTP compared to placebo (HR range, 0.45-0.72). Sunitinib (HR = 1.99) and nintedanib (HR = 2.17) showed a significant decline on TTP compared to lenvatinib. Vandetanib (HR = 0.44) and sorafenib (HR = 0.73) showed a significant improvement on OS compared to placebo. There was no significant difference in PFS, ORR and G3-5AE across different drugs. According to cluster rank analysis, vandetanib was the drug with both more effective (OS) and more secure (G3-5AE) compared to Sor followed by nintedanib. CONCLUSIONS:This network meta-analysis shows that vandetanib, linifanib, lenvatinib and nintedanib potentially may be the best substitution of sorafenib against advanced HCC as first-line targeted drugs. Vandetanib seems to be the best choise with low quality of evidence. For better survival, novel targeted treatment options for HCC are sorely needed.

Project description:BackgroundSeveral systemic agents have been approved for use in advanced hepatocellular carcinoma (aHCC). However, it is unclear which treatment is superior in either the first- or second-line settings due to the paucity of head-to-head comparative trials. Therefore, we have conducted a systematic review and network meta-analysis for the indirect comparison of the systemic agents in the first line and second line settings.MethodsRandomized clinical trials evaluating systemic agents in first and second line settings in aHCC from inception to April 2020 were identified by searching PubMed, EMBASE, and Cochrane Databases and the annual ASCO and ESMO conferences from 2017 to 2020. Studies in English reporting clinical outcomes including overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) were included. The primary outcomes of interest were pooled hazard ratios (HR) of OS and pooled odds ratios (OR) of ORR in first line studies and pooled HR of PFS and OR of ORR for second line studies. Additionally, OS for second line agents were reported in the qualitative analysis.ResultsOverall, first line studies comprised 8335 patients (13 studies) and second line studies comprised 4612 patients (11 studies). In the first line setting, atezolizumab plus bevacizumab was associated with the highest OS benefit over sorafenib (HR 0.58, 95% CI, 0.42-0.80; P-score 0.993). Additionally, lenvatinib was associated with the greatest ORR benefit (OR 3.34, 95% CI, 2.17-5.14; P-score 0.080) in the first line setting. In the second line setting, cabozantinib was associated with the highest PFS benefit over placebo (HR 0.44, 95% CI, 0.29-0.66; P-score 0.854) as well as the highest ORR benefit (OR 9.40, 95% CI, 1.25-70.83, P-score, 0.266).ConclusionAtezolizumab plus bevacizumab appears to have superior efficacy among first line agents whereas cabozantinib appears to be superior in the second line setting. Further studies are warranted to determine whether the type of prior therapy received affects the efficacy of subsequent second line therapy.
