Abstract

Background

There are no proven or approved second-line systemic treatment options for HCC. We evaluated regorafenib, an oral multikinase inhibitor, in patients with HCC who had disease progression on sorafenib.

Methods

Adults with BCLC stage B or C HCC who had radiological progression on sorafenib, Child-Pugh A liver function, and ECOG PS 0–1 were randomized 2:1 to regorafenib 160 mg/day or placebo on weeks 1–3 of each 4-week cycle until progression, death, or unacceptable toxicity. The primary endpoint was overall survival (OS). HRQoL was assessed by the FACT-Hep and EQ-5D questionnaires.

Results

A total of 573 patients were randomized (regorafenib 379; placebo 194) and baseline characteristics were balanced. The regorafenib group had a 37% reduction in the risk of death (HR 0.63; 95%CI 0.50–0.79; p < 0.001); median OS (regorafenib vs placebo) was 10.6 vs 7.8 months. Regorafenib improved progression-free survival (HR 0.46; 95%CI 0.37–0.56; p < 0.001), time to progression (HR 0.44; 95%CI 0.36–0.55; p < 0.001), and the disease control rate (65.2% vs 36.1%; p < 0.001). Rates of grade ≥3 adverse events were 79.7% with regorafenib and 58.5% with placebo. Most common grade ≥3 adverse events occurring more frequently with regorafenib included hypertension (15.2% vs 4.7%), hand–foot skin reaction (12.6% vs 0.5%), fatigue (9.1% vs 4.7%), and diarrhea (3.2% vs 0%). The EQ-5D index, EQ-5D VAS, and FACT-G scores were similar in the treatment groups (Table). Although the FACT-Hep total score favored placebo, the difference did not meet the established minimally important threshold of 8–9 points.

Least square mean (LSM) time-adjusted AUC (95% CI) Regorafenib Placebo P-value
EQ-5D index 0.76 (0.75–0.78) 0.77 (0.75–0.79) 0.47
EQ-5D visual analogue scale (VAS) 71.68 (70.46–72.90) 73.45 (71.84–75.06) 0.06
Functional Assessment of Cancer Therapy-General (FACT-G) 75.14 (74.12–76.16) 76.55 (75.20–77.90) 0.07
FACT-Hep total 129.31 (127.84–130.79) 133.17 (131.21–135.12)

Conclusions

Regorafenib significantly improved OS in patients with HCC who progressed during sorafenib treatment. Adverse events were consistent with the known safety profile of regorafenib with no clinically meaningful differences in HRQoL between groups.
