Array BioPharma Initiates Phase I Clinical Trial for Targeted Anticancer Drug ARRY-334543
BOULDER, Colo., Jan. 17 /PRNewswire-FirstCall/ -- Array BioPharma Inc. (Nasdaq: ARRY) has initiated dosing cancer patients in a Phase I clinical trial for its targeted small molecule anticancer drug ARRY-334543. ARRY-334543 is an oral, selective, reversible, small molecule tyrosine kinase inhibitor of both ErbB-2 (Her-2/neu) and EGFR. Over-expression of ErbB-2 and EGFR receptors in tumors is predictive of poor prognosis in cancer patients. ARRY-334543 has shown significant anti-tumor activity in preclinical models of human breast, lung, and epidermal carcinoma tumors.
"Advancing ARRY-334543 into clinical trials is a significant achievement for Array and further demonstrates our ability to invent novel therapies for cancer patients," said Kevin Koch, Ph.D., President and Chief Scientific Officer. "ARRY-334543 is our second targeted cancer agent resulting from our internal drug discovery program and furthers our goal of building the industry's leading clinical pipeline of small molecule drugs."
The open-label, dose-escalation trial is designed to evaluate tolerability and pharmacokinetics of ARRY-334543 following oral administration to patients with advanced cancer. In addition, the trial is designed to examine indicators of therapeutic activity in these patients.
ARRY-334543 is an orally active, reversible, enzymatic and cellular inhibitor, with nanomolar potency, of the key growth factor receptor tyrosine kinases ErbB-2 and EGFR. The compound possesses improved physiochemical properties relative to compounds directed at these targets currently in clinical development, and provides superior exposure and equivalent or greater efficacy in animal models of human cancer.
Currently, there is no single drug on the market that selectively inhibits both ErbB-2 and EGFR. ARRY-334543, which concurrently inhibits the molecular targets of the drugs Herceptin(R) (ErbB-2) and Erbitux(R) (EGFR), may provide enhanced efficacy in the treatment of cancer patients.
