2017
4000Background: Tivantinib (T), a selective, oral MET inhibitor, improved overall survival (OS) and progression-free survival (PFS) versus placebo (P) in a phase II study in MET-High HCC pts. Methods: This randomized, placebo-controlled phase III trial (NCT01755767) enrolled pts with: advanced HCC; Child Pugh A; ECOG PS ≤1; adequate bone marrow, liver, kidney functions; no liver transplant; radiographic disease progression (PD) after or intolerance to sorafenib; tumor MET-High (MET ≥2+ in ≥50% of tumor cells) by centralized immunohistochemistry. Pts were randomly assigned 2:1 to oral T or P, stratified by vascular invasion (VI), extrahepatic spread (ES), AFP ( 200ng/mL), treated until PD or unacceptable toxicity. Response (RECIST 1.1) was evaluated by CT / MRI every 8 weeks. Primary endpoint of OS and secondary endpoints including PFS and safety were assessed in the intent-to-treat (ITT) population. Results: From Dec 2012 to Dec 2015, 1209 pts were consented in Australia, the Americas, Europe, New Z...
