- Аннотация: Background & Aims: IMbrave150 demonstrated that atezolizumab plus bevacizumab led to significantly improved overall survival (OS) and progression-free survival (PFS) compared with sorafenib in patients with unresectable hepatocellular carcinoma at the primary analysis (after a median 8.6 months of follow-up). We present updated data after 12 months of additional follow-up. Methods: Patients with systemic treatment-naive, unresectable hepatocellular carcinoma were randomized 2:1 to receive 1,200 mg atezolizumab plus 15 mg/kg bevacizumab intravenously every 3 weeks or 400 mg sorafenib orally twice daily in this open-label, phase III study. Co-primary endpoints were OS and PFS by independently assessed RECIST 1.1 in the intention-to-treat population. Secondary efficacy endpoints included objective response rates and exploratory subgroup efficacy analyses. This is a post hoc updated analysis of efficacy and safety. Results: From March 15, 2018, to January 30, 2019, 501 patients (intention-to-treat population) were randomly allocated to receive atezolizumab plus bevacizumab (n = 336) or sorafenib (n = 165). On August 31, 2020, after a median 15.6 (range, 0-28.6) months of follow-up, the median OS was 19.2 months (95% CI 17.0–23.7) with atezolizumab plus bevacizumab and 13.4 months (95% CI 11.4–16.9) with sorafenib (hazard ratio [HR] 0.66; 95% CI 0.52-0.85; descriptive p <0.001). The median PFS was 6.9 (95% CI 5.7-8.6) and 4.3 (95% CI 4.0-5.6) months in the respective treatment groups (HR 0.65; 95% CI 0.53-0.81; descriptive p < 0.001). Treatment-related grade 3/4 adverse events occurred in 143 (43%) of 329 and 72 (46%) of 156 safety-evaluable patients in the respective groups, and treatment-related grade 5 events occurred in 6 (2%) and 1 (<1%) patients. Conclusion: After longer follow-up, atezolizumab plus bevacizumab maintained clinically meaningful survival benefits over sorafenib and had a safety profile consistent with the primary analysis. ClinicalTrials.gov identifier: NCT03434379. Lay summary: The primary analysis of IMbrave150 showed that atezolizumab plus bevacizumab had significantly greater benefits than sorafenib in patients with advanced hepatocellular carcinoma, but survival data were not yet mature. At this updated analysis done 12 months later, median overall survival was 5.8 months longer with atezolizumab plus bevacizumab than sorafenib, and the severity profile of treatment-related side effects remained similar. These updated results confirm atezolizumab plus bevacizumab as the first-line standard of care for advanced hepatocellular carcinoma.
