The evidence supporting this protocol comes from a multicentre, phase 3, randomised, open-label, non-inferiority study of patients with unresectable hepatocellular carcinoma.r
Between March 2013 and July 2015, a total of 954 patients were randomised to receive lenvatinib (12 mg/day for bodyweight ≥ 60 kg or 8 mg/day for bodyweight <60 kg) (n=478) or sorafenib 400 mg twice daily (n=476) in 28 day cycles. Most patients were <65 years old (58%), male (84%), Asian (69%), ≥60 kg (69%), ECOG PS 0 (63%), and Barcelona Clinic Liver Cancer stage C (79%).r
The primary endpoint was overall survival. Secondary endpoints included progression-free survival, time to progression, objective response rate and quality of life measurements. The study was powered to determine non-inferiority if the upper limit of the two-sided 95% CI for HR was less than 1.08.r
Efficacy
After a median follow up of 27.7 months in the lenvatinib group, and 27.2 months in the sorafenib group, lenvatinib showed non-inferiority in terms of overall survival compared to sorafenib. The median overall survival was 13.6 months in the lenvatinib group and 12.3 months in the sorafenib group, with a hazard ratio of 0.92 (95% CI 0.79 to 1.06).r

Both groups had similar baseline scores on quality of life measures (EORTC QLQ-C30 and EORTC QLQ-HCC18), and both groups had declining scores over time. A decline in pain, diarrhoea, nutrition and body image occurred earlier in the sorafenib arm compared to the lenvatinib arm, although the summary scores were comparable.r
Toxicity
The most common treatment-related adverse events for lenvatinib were hypertension, diarrhoea, anorexia and weight loss. Of those taking lenvatinib, treatment-related adverse events led to drug interruption in 40% (compared with 32% in the sorafenib arm), dose reduction in 37% (compared with 38%) and withdrawal in 9% (compared with 7%). There were 11 (2%) fatal adverse events in the lenvatinib arm which included hepatic failure (n=3), cerebral haemorrhage (n=3), and respiratory failure (n=2). There were 4 (1%) fatal adverse events in the sorafenib arm, from tumour haemorrhage, ischaemic stroke, respiratory failure and sudden death.r
