For many years, sorafenib was the only FDA-approved systemic treatment for patients with uHCC. Initial case reports of remarkable responses of tumors to immunotherapy, and results of the Phase I/II CheckMate-040 clinical trial, led to the September 2017 FDA approval of nivolumab for the treatment of patients with uHCC after progression on sorafenib. Thereafter, several randomized clinical trials comparing sorafenib to immunotherapy and immunotherapy combinations were initiated, including the comparison of nivolumab to sorafenib. In June 2019 it was announced that this trial did not reach its prespecified endpoint, and the FDA approval for the uHCC indication was voluntarily withdrawn. In December 2021, Yau et al published the final results of the CheckMate-459 randomized trial that included 743 adult patients with advanced HCC randomly assigned to receive either nivolumab (n=371) or sorafenib (n=372) in the first line setting. The primary endpoint was overall survival (OS) assessed in the intention-to-treat population. The median OS was 16.4 months (95% CI 13.9–18.4) with nivolumab and 14.7 months (11.9–17.2) with sorafenib (hazard ratio 0.85 [95% CI 0.72–1.02]; P = 0.075; minimum follow-up 22.8 months). Serious treatment-related adverse events were reported in 43 (12%) patients receiving nivolumab and 39 (11%) patients receiving sorafenib. The authors concluded that though first-line nivolumab treatment did not significantly improve OS compared with sorafenib, single-agent nivolumab might be considered a treatment option for patients in whom tyrosine kinase inhibitors or antiangiogenic drugs are not safe.
Cheng et al reported an update on the outcomes of the IMbrave150 study, 12 months after the primary analysis. This study established atezolizumab and bevacizumab as the current standard of care for the initial systemic treatment of patients with uHCC. The median OS was 19.2 months (95% CI 17.0-23.7) with atezolizumab/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 overall response rate (ORR) was 30% with atezolizumab/bevacizumab, while treatment-related grade 3/4 adverse events occurred in 143 (43%) of 329 receiving atezolizumab/bevacizumab and 72 (46%) of 156 receiving sorafenib. Treatment-related grade 5 events occurred in 6 (2%) and 1 (<1%) patients. Therefore, atezolizumab/bevacizumab remains the first-line standard of care for patients with uHCC.
Finally, Jácome et al undertook a combined analysis of 3 randomized controlled trials (KEYNOTE-240, CheckMate-459, and IMbrave150), with 1,657 patients with uHCC and who were treated with either immunotherapy (n=985) or sorafenib (in the first-line setting) or placebo (in the sorafenib-refractory setting) (n=672). The conclusion of the meta-analysis was that checkpoint inhibitors were associated with superior OS (HR, 0.75; P = .006), progression-free survival (HR, 0.74; P = .03), and ORR (odds ratio [OR], 2.82; P < .001) and lower odds of grade 3 or 4 treatment-related adverse events (OR, 0.44; P = .04) than the comparators, confirming that immunotherapy remains an integral part of the treatment of patients with uHCC.
