A phase II trial of second‐line axitinib following prior antiangiogenic therapy in advanced hepatocellular carcinoma
2013
314 Background: Second-line options in treatment of HCC are limited. Axitinib is a multi-targeted tyrosine kinase inhibitor (TKI) of VEGFRs 1, 2, and 3, PDGFR and c-KIT that warrants exploration in HCC. Methods: This is an open-label, single-arm, two-stage phase II trial of axitinib in advanced HCC. Eligible patients (pts) are Child-Pugh A/B7, with measurable progressive disease after TKIs/antiangiogenic drugs. Axitinib starts at 5 mg bid orally, titrated to 10 mg bid as tolerated. Treatment continues to progression (PD) or intolerable toxicity. Primary endpoint is response defined by reduction in size by RECIST 1.1 on CT scan at 16 wks, secondary endpoints to compare response by RECIST 1.1 to Choi criteria and modified RECIST, explore dynamic imaging models, feasibility, safety, PFS and overall survival. Results: We present results of 15 (of 29) pts enrolled from 01/11 - 09/12. Median age; 62y (range 18-78) with ECOG PS 0 (5 pts), 1 (10 pts) with prior therapy of Temsirolimus/Bevacizumab (2 pts), sorafen...
