ArQule Presents Additional Clinical Biomarker Data From Phase 2 Study of Tivantinib in Hepatocellular Carcinoma at International Liver Cancer Association Conference

ArQule, Inc.

today announced that additional analyses of plasma biomarkers support the prognostic and predictive role of MET status in this previously reported phase 2 trial in hepatocellular carcinoma (HCC). The data was presented at the International Liver Cancer Association (ILCA) 9th Annual Conference on September 6th, 2015. The phase 2 study, completed in the third quarter of 2011 and published in The Lancet Oncology medical journal in November 2012, enrolled 107 HCC patients who progressed or were intolerant to one prior systemic therapy. Multiple biomarkers were evaluated as part of the study, and MET status as determined by immunohistochemistry emerged as the strongest predictor of tivantinib benefit. In addition, the presentation noted that biopsies were more likely to be categorized as MET-high when taken after sorafenib therapy than before therapy. The presentation can be accessed in the "Investor and Media" section of our website, www.arqule.com, under "Recent Data Presentations." "The biomarker data from this trial demonstrates that patients with MET-high tumors are more likely to benefit from tivantinib therapy," said Dr. Brian Schwartz, head of research and development at ArQule. "On the basis of the results from the phase 2 trial and in partnership with Daiichi Sankyo, we are conducting the pivotal phase 3 METIV-HCC trial that is enrolling MET-high HCC patients as determined by a required companion diagnostic test." By the end of 2015 the pivotal phase 3 trial, METIV-HCC, is expected to complete enrollment of approximately 300 patients, randomized 2:1 treatment to best supportive care, with the primary end-point of overall survival.
