ArQule liver cancer med fails another Phase 3 trial

March 28, 2017

ArQule, Inc. (Nasdaq: ARQL) today reported that its partner, Kyowa Hakko Kirin, announced top-line results of the JET-HCC Phase 3 trial of tivantinib in Japan, and that the trial did not meet its primary endpoint of progression free survival (PFS).

JET-HCC is a randomized, double-blind placebo-controlled study that enrolled approximately 190 Japanese patients with c-Met diagnostic-high inoperable hepatocellular carcinoma (HCC) with a history of prior sorafenib therapy, to evaluate the efficacy and safety of tivantinib.

The primary endpoint of the trial is PFS, and the top-line results did not show a significant difference in PFS between the tivantinib group and the placebo group. There were no new safety issues observed in the trial.

The details of the study results will be presented in an upcoming scientific forum.

“I would like to thank our partner, Kyowa Hakko Kirin, and all the participants in their study,” said Paolo Pucci, Chief Executive Officer of ArQule. “The results are disappointing as there is a need for a second-line HCC therapy in Japan.”
