Tivantinib in HCC Second-Line, MET Diagnostic-High Ph3 Pivotal Single Agent Trial (METIV-HCC* in the West) HCC Inoperable locally adv/metastatic disease Prior sorafenib treatment MET diagnostic-high (assessed by IHC) Companion diagnostic R A N D O M I Z E 2 : 1 Tivantinib 120 mg tablet BID** ~200 pts Placebo ~100 pts Stratification Factors Vascular invasion Extra-hepatic spread AFP (< or > 200 ng/ml) Endpoints 1 o : OS 2 : PFS, safety 3 : ORR, DCR, TTP, PD, PK, biomarkers * Sponsors: ArQule and Daiichi Sankyo **Dose reduced from 240 mg tablet twice daily (BID) to 120 mg tablet BID following observation of higher incidence of neutropenia. DMC safety analysis of reduced dose cleared the trial to proceed. PK analysis of DMC-determined cohort demonstrated that 120 mg tablet BID has comparable exposure to 240 mg capsule as per the Ph 2 trial data. 8

Statistical Assumptions for METIV-HCC Trial Primary endpoint OS > 257 events required Median OS 7.7 months in treatment arm 5.0 months in placebo arm Hazard ratio = 0.65 Interim analysis ~ 154 OS events (60 percent of OS events) Efficacy stop, no futility stop, minimal alpha spend 10
Ongoing Ph 3 METIV HCC Trial is Based on Successful Ph 2 Randomized, Placebo-Controlled, Double-Blind Trial Study met primary endpoint in second-line HCC (ITT population), with statistically significant 56% improvement in time-to-progression (HR = 0.64, log rank p-value = 0.04) OS in MET-High Patients and Prognostic Implication of MET Major improvements seen in MET+ patients OS (7.2 mos. vs. 3.8 mos., HR=0.38, log rank p-value=0.01) TTP (2.9 mos. vs. 1.5 mos., HR=0.43, log rank p-value=0.03) PFS (2.4 mos. vs. 1.5 mos., 0.45, log rank p-value=0.02) AEs reported at similar rates in both arms except for higher incidence of fatigue and hematologic events, which declined with dose reduction Tivantinib in MET-high hepatocellular carcinoma patients and the ongoing Phase III clinical trial, published in Hepatic Oncology, posted online Jan. 29. 2014 http://www.futuremedicine.com/doi/full/10.2217/hep.14.3#_i14 11
MET, HCC and Tivantinib: Recent Literature Among all these pathways, c-met is currently the most promising target, thanks to a proven prognostic role and a putative predictive value for patient selection. 1 Tivantinib (ARQ 197) is, at present, the most widely investigated c-met tyrosine kinase inhibitor in HCC. 1 High MET expression evaluated by immunohistochemistry seems to select patients with higher chances of benefit. 1 The development of tivantinib, a small molecule inhibitor of the MET receptor can serve as a paradigm. 2 A randomized phase II study was performed with correlative biomarker work showing that high Met-expression may identify a group of patients that benefit most from the drug. 2 1 Dissecting signaling pathways in hepatocellular carcinoma: new perspectives in medical therapy; Future Oncol.
