Lenvatinib is an oral tyrosine kinase inhibitor targeting VEGFR1-3, FGFR1-4, RET, KIT and PDGFR�. The inherent vascularity of HCC makes it a target for VEGF inhibitors and other molecular mediators of angiogenesis like FGFR and PDGFR. The current study established a MTD of lenvatinib for HCC patients with Child-Pugh A of 12 mg qd. The current presentation is a report on the efficacy and safety of lenvatinib.


Between July 9, 2010 and June 22, 2011, 46 pts with advanced HCC and Child-Pugh A status were enrolled in Japan (n = 43) and Korea (n = 3). Pts may have received up to one prior treatment regimen including sorafenib. Pts were treated with a starting dose of lenvatinib 12 mg once daily in 28 day cycles until disease progression or development of unmanageable toxicities. Response was assessed by RECIST 1.1 (modified to evaluate viable lesions) by independent radiologist review (IRR).


46 pts were enrolled (med age: 67; M: 72%) and were evaluable for response. 76% of pts required dose adjustments for management of toxicity. The most common adverse events were hypertension 76% (Gr3: 54%), palmar-plantar erythrodysaesthesia syndrome 65% (Gr3: 9%), anorexia 59% (Gr3: 2.2%), proteinuria 54% (Gr3: 17%), fatigue 54% (Gr3: 0%), and thrombocytopenia 52% (Gr3: 33%). A higher level of toxicity was observed in pts weighing < 60 kg compared to pts ≥ 60 kg correlating with differences in drug exposure. ORR based on IRR is (PR = 32.6%, SD = 45.7%). Median Time to progression (TTP) is 7.49 mo (95% CI: 5.45 - 9.43)(based on minimum 6 mo. f/u, with 56.5% progression events) based on IRR. Median overall survival (OS) is 13.9 mo (95% CI: 11.8 -) (based on minimum 8 mo. f/u, with 46% death events). OS data has not yet matured and will be reported in the future.


In this Phase I/II study, lenvatinib administered to patients with advanced HCC was not associated with any new toxicities associated with TKI class and was managed by dose adjustments. A weight-based starting dose (<60 Kg: 8 mg qd, vs ≥60kg: 12 mg qd) may be appropriate to minimize toxicity due to higher drug exposure in pts < 60 kg. The observed OS and TTP indicate lenvatinib has activity in patients with advanced HCC and may be a new therapeutic option.
