Transarterial Radioembolization Versus Atezolizumab-Bevacizumab in Unresectable Hepatocellular Carcinoma: A Matching-Adjusted Indirect Comparison of Time to Deterioration in Quality of Life.

ABSTRACT:

Introduction

Given the relatively short life expectancy of patients with hepatocellular carcinoma (HCC), quality of life (QOL) plays a significant role in treatment selection. This analysis aimed to compare time to deterioration (TTD) in QOL with transarterial radioembolization (TARE) and atezolizumab-bevacizumab, as well as sorafenib, in advanced and unresectable HCC.

Methods

Patient-level data from SARAH (TARE using SIR-Spheres^® Y-90 resin microspheres [SIR-Spheres] versus sorafenib) and aggregate data from IMbrave150 (atezolizumab-bevacizumab versus sorafenib) randomized controlled trials were used to conduct an anchored matching-adjusted indirect comparison (MAIC). Patients with a Child-Pugh score B in SARAH were excluded to align with exclusion criteria in IMbrave150. To identify potential effect modifiers for adjustment, the literature was searched and multivariate Cox proportional hazards models were implemented using SARAH data. Patients from SARAH were then weighted to balance with baseline characteristics from IMbrave150. Median TTD in QOL and hazard ratios (HRs) were calculated.

Results

Four potential effect modifiers were identified and used for adjustment: cause of disease (viral/non-viral), macrovascular invasion, Eastern Cooperative Oncology Group performance score, and alpha-fetoprotein level. The MAIC included 217 patients from SARAH (TARE = 94; sorafenib = 123). Median TTD in QOL was 11.23 and 8.64 months for atezolizumab-bevacizumab and TARE, respectively (HR = 1.06; 95% confidence interval [CI] 0.75-1.50; p = 0.725). A sensitivity analysis was conducted adjusting for cause of disease defined as hepatitis B/hepatitis C/non-viral: median TTD in QOL was higher for TARE compared with atezolizumab-bevacizumab (19.88 vs 11.23 months; HR = 0.66; 95% CI 0.36-1.19; p = 0.163). Sorafenib resulted in the shortest TTD in QOL, with statistically significant differences in both base case and sensitivity analyses.

Conclusion

TARE using SIR-Spheres may achieve similar TTD in QOL compared with atezolizumab-bevacizumab, as the analyses found no statistically significant differences between these two interventions. Both TARE using SIR-Spheres and atezolizumab-bevacizumab seem to be more efficacious than sorafenib in maintaining QOL.

Project description:BackgroundA growing body of evidence suggests that non-viral hepatocellular carcinoma (HCC) might benefit less from immunotherapy.Materials and methodsWe carried out a retrospective analysis of prospectively collected data from consecutive patients with non-viral advanced HCC, treated with atezolizumab plus bevacizumab, lenvatinib, or sorafenib, in 36 centers in 4 countries (Italy, Japan, Republic of Korea, and UK). The primary endpoint was overall survival (OS) with atezolizumab plus bevacizumab versus lenvatinib. Secondary endpoints were progression-free survival (PFS) with atezolizumab plus bevacizumab versus lenvatinib, and OS and PFS with atezolizumab plus bevacizumab versus sorafenib. For the primary and secondary endpoints, we carried out the analysis on the whole population first, and then we divided the cohort into two groups: non-alcoholic fatty liver disease (NAFLD)/non-alcoholic steatohepatitis (NASH) population and non-NAFLD/NASH population.ResultsOne hundred and ninety patients received atezolizumab plus bevacizumab, 569 patients received lenvatinib, and 210 patients received sorafenib. In the whole population, multivariate analysis showed that treatment with lenvatinib was associated with a longer OS [hazard ratio (HR) 0.65; 95% confidence interval (CI) 0.44-0.95; P = 0.0268] and PFS (HR 0.67; 95% CI 0.51-0.86; P = 0.002) compared to atezolizumab plus bevacizumab. In the NAFLD/NASH population, multivariate analysis confirmed that lenvatinib treatment was associated with a longer OS (HR 0.46; 95% CI 0.26-0.84; P = 0.0110) and PFS (HR 0.55; 95% CI 0.38-0.82; P = 0.031) compared to atezolizumab plus bevacizumab. In the subgroup of non-NAFLD/NASH patients, no difference in OS or PFS was observed between patients treated with lenvatinib and those treated with atezolizumab plus bevacizumab. All these results were confirmed following propensity score matching analysis. By comparing patients receiving atezolizumab plus bevacizumab versus sorafenib, no statistically significant difference in survival was observed.ConclusionsThe present analysis conducted on a large number of advanced non-viral HCC patients showed for the first time that treatment with lenvatinib is associated with a significant survival benefit compared to atezolizumab plus bevacizumab, in particular in patients with NAFLD/NASH-related HCC.

Project description:BackgroundAlthough atezolizumab plus bevacizumab (Atez/bev) treatment has been developed for unresectable hepatocellular carcinoma (u-HCC), changes in hepatic function during therapy have yet to be reported.AimThis retrospective clinical study aimed to elucidate early responses to Atez/Bev.MethodsFrom September 2020 to April 2021, 171 u-HCC patients undergoing Atez/Bev treatment were enrolled (BCLC stage A:B:C:D = 5:68:96:2). Of those, 75 had no prior history of systemic treatment. Relative changes in hepatic function and therapeutic response were assessed using albumin-bilirubin (ALBI) score and Response Evaluation Criteria in Solid Tumors (RECIST), ver. 1.1, respectively.ResultsIn initial imaging examination findings, objective response rates for early tumor shrinkage and disease control after 6 weeks (ORR-6W/DCR-6W) were 10.6%/79.6%. Similar response results were observed in patients with and without a past history of systemic treatment (ORR-6W/DCR-6W = 9.7%/77.8% and 12.2%/82.9%), as well as patients in whom Atez/Bev was used as post-progression treatment following lenvatinib (ORR-6W/DCR-6W = 7.7%/79.5%), for which no known effective post-progression treatment has been established. In 111 patients who underwent a 6-week observation period, ALBI score was significantly worsened at 3 weeks after introducing Atez/Bev (-2.525 ± 0.419 vs -2.323 ± 0.445, p < .001), but then recovered at 6-weeks (-2.403 ± 0.452) as compared to 3-weeks (p = .001). During the observation period, the most common adverse events were appetite loss (all grades) (12.3%), general fatigue/hypertension (all grades) (11.1%, respectively), and urine protein (all grades) (10.5%).ConclusionAtez/Bev might have therapeutic potential not only as first but also later-line treatment of existing molecular target agents. In addition, this drug combination may have less influence on hepatic function during the early period, as the present patients showed a good initial therapeutic response.
