ArQule, Inc. (Nasdaq: ARQL) and Daiichi Sankyo, Co., Ltd. (TSE 4568) today announced that an oral presentation at the Annual Meeting of the American Society of Clinical Oncology (ASCO) will feature Phase 2 trial data with tivantinib as a single agent investigational second-line treatment in hepatocellular carcinoma (HCC). ArQule announced that this randomized, double-blind study met its primary endpoint in January and will now present the full results from this trial, including positive data in the pre-defined c-MET high population. Additional clinical data with tivantinib will be featured in two poster discussions and two general poster sessions. Abstracts of these presentations with tivantinib have been published on www.asco.org.
“These findings represent the first randomized data reported with an investigational c-MET inhibitor administered as a single agent second-line treatment in HCC”
"These findings represent the first randomized data reported with an investigational c-MET inhibitor administered as a single agent second-line treatment in HCC," said Paolo Pucci, chief executive officer of ArQule. "They clearly define c-MET high patients as a biological subgroup for potential targeted therapy with tivantinib. The robust statistical significance achieved in this trial reflects the anti-cancer activity of tivantinib alone and expands its therapeutic potential."
HCC Trial Summary: c-MET high patients
Data from the HCC trial demonstrated a statistically significant improvement in time-to-progression.
Previously announced top-line data from the HCC trial demonstrate that treatment with tivantinib produced a statistically significant 56 percent improvement in TTP in the intent-to-treat (ITT) population by central radiology review, the primary endpoint (HR = 0.64, log rank p-value = 0.04) in this trial. Adverse events were reported at similar rates in the treatment and placebo arms, except for a higher incidence of fatigue and hematologic events, including neutropenia and anemia, in tivantinib-treated patients. The incidence of hematologic events declined following dose reduction of tivantinib from 360 milligrams twice daily to 240 milligrams twice daily.
The schedule of this and other presentations of data with tivantinib is provided below. All times are Central Daylight Time.
