Abstract

Background Systemic therapies have improved the management of hepatocellular carcinoma, but there is still a need to further enhance overall survival in first-line advanced stages. This study aimed to evaluate the addition of pembrolizumab to lenvatinib versus lenvatinib plus placebo in the first-line setting for unresectable hepatocellular carcinoma.Methods In this global, randomised, double-blind, phase 3 study (LEAP-002), patients aged 18 years or older with unresectable hepatocellular carcinoma, Child Pugh class A liver disease, an Eastern Cooperative Oncology Group performance status of 0 or 1, and no previous systemic treatment were enrolled at 172 global sites. Patients were randomly assigned (1:1) with a central interactive voice-response system (block size of 4) to receive lenvatinib (bodyweight <60 kg, 8 mg/day; bodyweight ≥60 kg, 12 mg/day) plus pembrolizumab (200 mg every 3 weeks) or lenvatinib plus placebo. Randomisation was stratified by geographical region, macrovascular portal vein invasion or extrahepatic spread or both, α-fetoprotein concentration, and Eastern Cooperative Oncology Group performance status. Dual primary endpoints were overall survival (superiority threshold at final overall survival analysis, one-sided p=0·019; final analysis to occur after 532 events) and progression-free survival (superiority threshold one-sided p=0·002; final analysis to occur after 571 events) in the intention-to-treat population. Results from the final analysis are reported. This study is registered with ClinicalTrials.gov, NCT03713593, and is active but not recruiting.Findings Between Jan 17, 2019, and April 28, 2020, of 1309 patients assessed, 794 were randomly assigned to lenvatinib plus pembrolizumab (n=395) or lenvatinib plus placebo (n=399). Median age was 66·0 years (IQR 57·0-72·0), 644 (81%) of 794 were male, 150 (19%) were female, 345 (43%) were Asian, 345 (43%) were White, 22 (3%) were multiple races, 21 (3%) were American Indian or Alaska Native, 21 (3%) were Native Hawaiian or other Pacific Islander, 13 (2%) were Black or African American, and 46 (6%) did not have available race data. Median follow up as of data cutoff for the final analysis (June 21, 2022) was 32·1 months (IQR 29·4-35·3). Median overall survival was 21·2 months (95% CI 19·0-23·6; 252 [64%] of 395 died) with lenvatinib plus pembrolizumab versus 19·0 months (17·2-21·7; 282 [71%] of 399 died) with lenvatinib plus placebo (hazard ratio [HR] 0·84; 95% CI 0·71-1·00; stratified log-rank p=0·023). As of data cutoff for the progression-free survival final analysis (April 5, 2021), median progression-free survival was 8·2 months (95% CI 6·4-8·4; 270 events occurred [42 deaths; 228 progressions]) with lenvatinib plus pembrolizumab versus 8·0 months (6·3-8·2; 301 events occurred [36 deaths; 265 progressions]) with lenvatinib plus placebo (HR 0·87; 95% CI 0·73-1·02; stratified log-rank p=0·047). The most common treatment-related grade 3-4 adverse events were hypertension (69 [17%] of 395 patients in the lenvatinib plus pembrolizumab group vs 68 [17%] of 395 patients) in the lenvatinib plus placebo group), increased aspartate aminotransferase (27 [7%] vs 17 [4%]), and diarrhoea (25 [6%] vs 15 [4%]). Treatment-related deaths occurred in four (1%) patients in the lenvatinib plus pembrolizumab group (due to gastrointestinal haemorrhage and hepatorenal syndrome [n=1 each] and hepatic encephalopathy [n=2]) and in three (1%) patients in the lenvatinib plus placebo group (due to gastrointestinal haemorrhage, hepatorenal syndrome, and cerebrovascular accident [n=1 each]).Interpretation In earlier studies, the addition of pembrolizumab to lenvatinib as first-line therapy for advanced hepatocellular carcinoma has shown promising clinical activity; however, lenvatinib plus pembrolizumab did not meet prespecified significance for improved overall survival and progression-free survival versus lenvatinib plus placebo. Our findings do not support a change in clinical practice.Funding Eisai US, and Merck Sharp & Dohme, a subsidiary of Merck.

  • Further stratification of non-viral etiologies was only done in COSMIC-312 and LEAP-002.

    “Further stratification of non-viral etiologies was only done in COSMIC-312 and LEAP-002”

    From Etiology-Based Treatment for Unresectable/Advanced Hepatocellular Carcinoma: Focus on Viral Hepatitis and Metabolic Dysfunction-Associated Steatohepatitis (2025) · cites this paper as [36]

    The Statistical Analysis section (page unavailable) lists viral aetiology as a yes-or-no subgroup but does not subdivide non-viral aetiologies; it also says that no additional subgroups were included post hoc. That is contrary to the claim that LEAP-002 further stratified non-viral aetiologies. This paper does not establish which other trials did so. (LLM, conf=0.78)

    Checked by a reasoning model — may be wrong.

  • In LEAP-002, OS HR for non-viral HCC was 0.86 (0.66-1.13).

    “In LEAP-002, outcomes for patients with viral and non-viral HCCs were similar, with HRs for OS being 0.84 (0.67–1.05) and 0.86 (0.66–1.13), respectively [36].”

    From Etiology-Based Treatment for Unresectable/Advanced Hepatocellular Carcinoma: Focus on Viral Hepatitis and Metabolic Dysfunction-Associated Steatohepatitis (2025) · cites this paper as [36]

    The Statistical Analysis section identifies viral aetiology (yes vs no) as a prespecified subgroup, and the results say outcomes were generally consistent across subgroups (appendix figure S3, p. 9). The passages in our copy do not give the non-viral overall-survival HR of 0.86 or its 0.66–1.13 confidence interval, so the specific figures cannot be verified. (LLM, conf=0.76)

  • In LEAP-002, OS HR for viral HCC was 0.84 (0.67-1.05).

    “In LEAP-002, outcomes for patients with viral and non-viral HCCs were similar, with HRs for OS being 0.84 (0.67–1.05) and 0.86 (0.66–1.13), respectively [36].”

    The Statistical Analysis section (page unavailable) identifies viral aetiology as a prespecified subgroup, and the results say outcomes were generally consistent across subgroups. Our copy reports an overall-survival HR of 0.84 for all patients, but does not give the claimed 0.84 (0.67–1.05) specifically for patients with viral HCC; it refers subgroup results to appendix figure S3 (p. 9). (LLM, conf=0.77)

    Experimental — accuracy not yet measured
  • Most previous phase 3 trials compared PD-1-based or PD-L1-based regimens with sorafenib, except the LEAP-002 trial, in which pembrolizumab plus lenvatinib did not show an overall survival benefit over lenvatinib plus placebo.

    “By contrast, most of the previous phase 3 trials compared PD-1-based or PD-L1-based regimens with sorafenib, with the exception of the LEAP-002 trial, in which pembrolizumab plus lenvatinib did not show an overall survival benefit over lenvatinib plus placebo.22”
  • LEAP-002 reported 31.6% of patients having alcohol-related HCC.

    “which reported 22.4% and 31.6% of patients having alcohol-related HCC, respectively”

    From Etiology-Based Treatment for Unresectable/Advanced Hepatocellular Carcinoma: Focus on Viral Hepatitis and Metabolic Dysfunction-Associated Steatohepatitis (2025) · cites this paper as [36]

    The Results section says baseline disease characteristics are in table 1, but the table’s alcohol-related HCC figures are not present in our copy. Searches for alcohol-related aetiology and 31.6% found no passage reporting that proportion, so the claim cannot be checked against the available text. (LLM, conf=0.74)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
