REFLECT-a phase 3 trial comparing efficacy and safety of lenvatinib to sorafenib for the treatment of unresectable hepatocellular carcinoma: an analysis of Japanese subset.

ABSTRACT: BACKGROUND:A phase 3, multinational, randomized, non-inferiority trial (REFLECT) compared the efficacy and safety of lenvatinib (LEN) and sorafenib (SOR) in patients with unresectable hepatocellular carcinoma (uHCC). LEN had an effect on overall survival (OS) compared to SOR, statistically confirmed by non-inferiority [OS: median = 13.6 months vs. 12.3 months; hazard ratio (HR) 0.92, 95% confidence interval (CI) 0.79-1.06], and demonstrated statistically significant improvements in progression-free survival (PFS) and the objective response rate (ORR) in the overall population. The results of a subset analysis that evaluated the efficacy and safety of LEN and SOR in the Japanese population are reported. METHODS:The intent-to-treat population enrolled in Japan was analyzed. RESULTS:Of 954 patients in the overall population, 168 Japanese patients were assigned to the LEN arm (N = 81) or the SOR arm (N = 87). Median OS was 17.6 months for LEN vs. 17.8 months for SOR (HR 0.90; 95% CI 0.62-1.29). LEN showed statistically significant improvements over SOR in PFS (7.2 months vs. 4.6 months) and ORR (29.6% vs. 6.9%). The relative dose intensity of LEN and SOR in the Japanese population was lower than in the overall population. Frequently observed, related adverse events included palmar-plantar erythrodysaesthesia syndrome (PPES), hypertension, decreased appetite, and proteinuria in the LEN arm, and PPES, hypertension, diarrhea, and alopecia in the SOR arm. CONCLUSIONS:The efficacy and safety of LEN in the Japanese population were similar to those in the overall population of REFLECT. With manageable adverse events, LEN is a new treatment option for Japanese patients with uHCC. TRIAL REGISTRATION ID:ClinicalTrials.gov. No. NCT01761266.

Project description:BackgroundIn a global, phase III, open-label, noninferiority trial (REFLECT), lenvatinib demonstrated noninferiority to sorafenib in overall survival and a statistically significant increase in progression-free survival in patients with unresectable hepatocellular carcinoma (HCC). Recently, lenvatinib became the first agent in more than 10 years to receive approval as first-line therapy for unresectable HCC, along with the previously approved sorafenib. The objective of this study was to determine the comparative cost-effectiveness of lenvatinib and sorafenib as a first-line therapy of unresectable HCC.Materials and methodsA state-transition model of unresectable HCC was developed in the form of a cost-utility analysis. The model time horizon was 5 years; the efficacy of the model was informed by the REFLECT trial, and costs and utilities were obtained from published literature. Probabilistic sensitivity analyses and subgroup analyses were performed to test the robustness of the model.ResultsLenvatinib dominated sorafenib in the base case analysis. A probabilistic sensitivity analysis indicated that lenvatinib remains a cost-saving measure in 64.87% of the simulations. However, if the cost of sorafenib was reduced by 57%, lenvatinib would no longer be the dominant strategy.ConclusionLenvatinib offered a similar clinical effectiveness at a lower cost than sorafenib, suggesting that lenvatinib would be a cost-saving alternative in treating unresectable HCC. However, lenvatinib may fail to remain cost-saving if a significantly cheaper generic sorafenib becomes available.Implications for practiceThis analysis suggests an actionable clinical policy that will achieve cost saving. This cost-utility analysis showed that lenvatinib had a similar clinical effectiveness at a lower cost than sorafenib, indicating that lenvatinib may be a cost-saving measure in patients with unresectable HCC, in which $23,719 could be saved per patient. The introduction of a new therapeutic option for the first time in 10 years in Canada provides an important opportunity for clinicians, researchers, and health care decision-makers to explore potential modifications in recommendations and practice guidelines.

Project description:BackgroundLenvatinib and lenvatinib-based combination treatments are widely used in patients with unresectable hepatocellular carcinoma (uHCC) in clinical practice, but their curative effect and safety need further study in the real world.MethodsThis was a retrospective study involving patients with uHCC receiving lenvatinib monotherapy and lenvatinib-based combination treatment between Nov, 2018 and Sep, 2020 in Nanfang Hospital. Efficacy was evaluated with objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), time to tumor progression (TTP), and overall survival (OS). Treatment-related adverse events (TRAEs) were recorded and graded. Efficacy and safety of monotherapy and combination therapy were compared. Stratified analysis was performed according to systemic line of treatment and medication regimen for combination therapy.ResultsFor lenvatinib monotherapy (n = 39), OS and PFS were 80 weeks and 24.3 weeks, respectively. For combination treatment (n = 72), median OS and PFS were 99 weeks and 45.6 weeks, respectively. OS, PFS, and TTP for patients in the combination treatment cohort were significantly longer compared to those of patients in the monotreatment cohort (OS: P = 0.04, PFS: P = 0.003; TTP, P = 0.005). The incidence of TRAEs could be controlled both in the monotherapy cohort and the combination treatment cohort. In the monotherapy cohort, OS and PFS were significantly decreased in the second-line treatment group compared with the first-line treatment group, while no differences were observed in the combination cohort. The efficacy of triple therapy (lenvatinib plus PD-1 antibody plus TACE or HAIF) was similar to lenvatinib plus PD-1 antibody or lenvatinib plus TACE or HAIF.ConclusionsOur real-world study showed that lenvatinib monotherapy and lenvatinib-based combination therapy were well tolerated, with encouraging efficacies in patients with uHCC. Lenvatinib-based combination therapy showed a better curative effect compared with lenvatinib single-agent therapy. In patients who have failed first-line TKI treatment, lenvatinib-based combination therapy may be a better choice than lenvatinib single-agent therapy. Lenvatinib-based triple therapy may not have an advantage over dual therapy.
