Survival Trends in Sorafenib for Advanced Hepatocellular Carcinoma: A Reconstructed Individual Patient Data Meta-Analysis of Randomized Trials.

ABSTRACT:

Background

Emerging data suggest that outcomes for advanced hepatocellular carcinoma (HCC) treated with sorafenib may have improved over time. We aimed to provide robust, time-to-event estimates of survival outcomes for sorafenib in advanced HCC.

Summary

In this systematic review and individual patient data meta-analysis of randomized-controlled trials (RCTs), we searched MEDLINE and Embase from inception till September 2022 for RCTs that provided data for overall survival (OS) and progression-free survival (PFS) for sorafenib monotherapy as first-line systemic therapy for advanced HCC. We performed a pooled analysis using reconstructed individual participant data from published Kaplan-Meier curves to obtain robust estimates for OS and PFS. Of 1,599 articles identified, 29 studies (5,525 patients) met the inclusion criteria. Overall, the median OS was 10.4 (95% CI: 9.6-11.4) months. Median OS increased over time, from 9.8 (95% CI: 8.8-10.7) months in studies before 2015 to 13.4 (95% CI: 11.03-15.24) months in studies from 2015 onwards (p < 0.001). OS did not differ by trial phase, geographical region, or study design. The overall median PFS was 4.4 (95% CI: 3.9-4.8) months, but PFS did not improve over time. Sensitivity analysis of studies from 2015 and onwards to account for the introduction of direct-acting antivirals determined that hepatitis C virus was associated with reduced mortality (p < 0.001). There was minimal heterogeneity in the estimates for OS (all I² ≤ 33).

Project description:BackgroundSorafenib has consistently served as the control arm in multiple randomized clinical trials (RCTs) evaluating novel therapies for advanced hepatocellular carcinoma (HCC) for more than a decade. Analyzing trends in clinical outcomes of patients treated with sorafenib for the same indication over time offers the opportunity for unique insight into the evolution of clinical trial conduct and potential non-drug factors impacting outcomes.MethodsWe identified RCTs in patients with treatment-naïve advanced HCC where sorafenib was compared to another systemic therapy or placebo. We extracted trial-level demographic, clinicopathologic, and outcome data (overall survival [OS], progression-free survival [PFS], objective response rate [ORR], and duration of therapy). Sample-weighted linear regression was used to identify temporal trends with significance set at p ≤ 0.05.ResultsSixteen RCTs (9 phase III and 7 phase II) enrolling 4,086 patients treated with sorafenib were included in the analysis. Included trials enrolled patients from 2005 to 2019. OS has significantly improved by 4.5 months from 2005 to 2019 (p = 0.048) over time. Thirteen studies provided data on PFS using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, with no significant change over time (p = 0.69). ORR assessed by RECIST 1.1 has significantly improved by 6.0% over time (p = 0.003). Median duration of therapy with sorafenib has decreased by 53% since the enrollment of the first clinical trial in 2005, from 23.1 weeks to 12.2 weeks (p = 0.0037). There was no significant change in patient demographics were identified over time to explain the OS findings.ConclusionThe median OS of patients with advanced HCC treated with sorafenib has improved significantly over 15 years. At the same time, the median duration of therapy with sorafenib has decreased. The reason for these findings was not explained by changing demographics of patients enrolled in these trials and has implications for ongoing clinical trials.

Project description:BackgroundUntreated advanced hepatocellular carcinoma (HCC) has an overall poor prognosis. Currently there are 2 ongoing prospective randomized controlled trials that are evaluating the efficacy and safety of sorafenib and selective internal radiation therapy (SIRT) with yttrium-90 resin microspheres in patients with advanced HCC. The SorAfenib versus Radioembolisation in Advanced Hepatocellular carcinoma (SARAH; 459 patients) trial is being performed in Europe and the SIRt VErsus SorafeNIB (SIRveNIB; 360 patients) trial in the Asia Pacific region. Prospectively combining the results, these trials will not only allow for increased precision to estimate efficacy (in terms of survival), but will also provide increased statistical power for subgroup analyses.ObjectiveTo ensure the prospectivity and transparency of the meta-analysis.MethodsThe sirVEnib and SARAH merge PROject (VESPRO) is an individual, patient-data prospective meta-analysis of the SIRveNIB and SARAH randomized trials. The VESPRO protocol includes prespecified hypotheses, inclusion criteria, and outcome measures. The primary outcome measure is overall survival and secondary outcomes include tumor response rate, progression-free survival, progression in the liver as first event, and disease control in the liver. Pooling of toxicity results will allow for robust safety profiles to be established for both therapies, and provides increased statistical power to investigate treatment effects in key subgroups. Analyses will be performed in the intent-to-treat population stratified by trial.ResultsBoth studies are expected to demonstrate a survival benefit for SIRT together with a better toxicity profile compared with sorafenib. It is also anticipated that liver progression as the first event would be longer in the intervention compared with the control.ConclusionsAs the results of the 2 trials are not yet known, the methodological strength is enhanced, as biases inherent in conventional meta-analyses are avoided. This has the effect of providing this meta-analysis with the advantages of a single, large,randomized study of 819 patients. It is anticipated that the SARAH and SIRveNIB trial results will be published separately and together with the combined meta-analysis results from VESPRO. The combined dataset will allow the effect of the interventions to be explored with improved reliability/precision with respect to prespecified patient and intervention-level characteristics.Trial registrationAustralian New Zealand Trials Registry: ACTRN12617000030370.

Project description:BackgroundPhase III trials show sorafenib improves survival in advanced hepatocellular carcinoma (HCC). Because of narrow trial eligibility, results may not be generalizable to a broader HCC population. We sought to evaluate the effectiveness of initial sorafenib versus no treatment among Medicare beneficiaries with advanced HCC.Materials and methodsPatients with advanced HCC diagnosed from 2008 to 2011 were identified from the Surveillance, Epidemiology, and End Results-Medicare database. Eligible patients received initial sorafenib or no therapy and were covered by Medicare parts A, B, and D. Sorafenib use and outcomes were described in this population. Using a propensity score (PS)-matched sample, we compared the effectiveness of sorafenib versus no treatment by Cox proportional hazards and binomial regression, using a landmark requiring all patients to survive ≥60 days after diagnosis.ResultsOf 1,532 patients, 27% received initial sorafenib. Median duration of sorafenib use was 60 days (interquartile range [IQR], 30-107 days), and median survival from first prescription was 3 months (IQR, 1-8 months). In the PS-matched cohort, median survival was 3 months from the 60-day landmark in sorafenib-treated (n = 223) and 2 months in untreated (n = 223) patients (adjusted hazard ratio, 0.95 [95% confidence interval (CI), 0.78-1.16]). Sorafenib was associated with a nonsignificant reduction in mortality at 3 months (44% versus 51%; adjusted risk ratio, 0.88 [95% CI, 0.72-1.07]), but no reduction thereafter.ConclusionSurvival after sorafenib initiation in newly diagnosed Medicare beneficiaries with HCC is exceptionally short, suggesting trial results are not generalizable to all HCC patients. The downsides of sorafenib use-high drug-related symptom burden and high drug cost-must be considered in light of this minimal benefit.Implications for practiceThe findings of a median survival of only 3 months in Medicare beneficiaries with HCC prescribed sorafenib as first-line therapy highlight the questionable value of sorafenib in this population. Patients should be cautioned that outside of the narrow confines of randomized trials, their life expectancy may be very short, and any benefit of sorafenib is likely to be quite small. Given that sorafenib causes considerable adverse effects and offers no symptom palliation, supportive care should be discussed as a reasonable alternative to sorafenib, particularly for patients who have a poor performance status or advanced cirrhosis.

Project description:Recently, a sum of trials of programmed cell death-1 (PD-1) inhibitors combined with chemotherapy have shown excellent efficacy compared to chemotherapy alone in patients with previously untreated, advanced esophageal squamous cell carcinoma (ESCC). However, there is no head-to-head comparison and consensus on which immunotherapy regimen results in better survival outcomes. This study aimed to evaluate the survival efficacy of various PD-1 inhibitor-based therapies in the first-line treatments for patients with advanced ESCC. Data collected prior to 31 July 2023 were searched in the PubMed, Cochrane Library, Embase, Medline, and Web of Science databases. Overall survival (OS) and progression-free survival curves were pooled using the MetaSurv package. Survival data were compared by reconstructed individual patient data. A total of 4,162 patients and seven randomized controlled trials were included. After synthesizing, PD-1 inhibitors prolonged median OS from 11.3 months (95% CI (confidence interval) 10.7-11.7) to 15.6 months (95% CI 14.7-16.3). Based on reconstructed patient-level data, the toripalimab, tislelizumab, and sintilimab group achieved the longest OS, whereas the sintilimab and tislelizumab group had the lowest risk of recurrence than other treatments. In patients with a combined positive score of ≥10, sintilimab had better OS efficacy than pembrolizumab (HR: 0.71, 95% CI: 0.52-0.96). In terms of tumor proportion score of ≥1%, camrelizumab, nivolumab, and toripalimab showed proximate survival benefits in both OS and progression-free survival. PD-1 inhibitor combined with chemotherapy significantly improved the survival time of patients with advanced ESCC. Toripalimab, tislelizumab, and sintilimab plus chemotherapy showed the best OS benefit. Longer progression-free benefits might be generated from adding tislelizumab and sintilimab to chemotherapy. Sintilimab was strongly recommended for patients with high programmed cell death-ligand 1 abundance. [https://www.crd.york.ac.uk/PROSPERO/], identifier [CRD42024501086].
