EntreMed's ENMD-2076 Demonstrates Tumor Regression in Human Colon Cancer Model

ROCKVILLE, Md., October 23, 2008 /PRNewswire-FirstCall/ -- EntreMed, Inc. , a clinical-stage pharmaceutical company developing therapeutics for the treatment of cancer and inflammatory diseases, today announced the presentation of preclinical data for its Aurora A/angiogenesis kinase inhibitor, ENMD-2076. The data were presented by John Tentler, Ph.D., Division of Medical Oncology, , at the 20th EORTC-NCI-AACR Annual Meeting being held this week in Geneva, Switzerland.

 

ENMD-2076 is a novel kinase inhibitor with potent activity against Aurora A and a number of tyrosine kinases linked to cancer and inflammatory diseases. ENMD-2076 demonstrated strong antitumor effects in a xenograft model of human colon cancer. Tumor stasis was seen at dose levels of 100 mg/kg/day, and tumor regression was observed at doses of 200 mg/kg ENMD-2076 per day. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and post-study histological examination of tumors suggest that the antitumor effects of ENMD-2076 are exerted through a combination of antiangiogenic and antiproliferative actions. Further analysis using positron emission tomography (PET) demonstrated a substantial decrease in tumor metabolic activity in animals treated with ENMD-2076.

ENMD-2076 exerts its effects through multiple mechanisms of action, including antiproliferative activity and the inhibition of angiogenesis. ENMD-2076 has demonstrated substantial dose-dependent efficacy as a single agent, including tumor regression, in multiple xenograft models (e.g. breast, colon, leukemia). Aurora kinases are key regulators of the process of mitosis, or cell division, and are often over-expressed in human cancers. In addition to the Aurora A isoform, ENMD-2076 has been shown to inhibit a distinct profile of angiogenic tyrosine kinase targets. ENMD-2076 is currently in a phase 1 clinical study in advanced cancer patients.

Dr. Mark R. Bray, Vice President Research at EntreMed commented on the presentation, "The exciting work presented by Dr. Tentler and his colleagues underscores the exceptional promise of ENMD-2076 as a novel anticancer therapeutic. Advanced non-invasive imaging using PET and DCE-MRI greatly increased the ability to monitor the antiangiogenic and antiproliferative mechanisms of ENMD-2076. We anticipate employing these techniques in upcoming ENMD-2076 clinical trials. EntreMed is actively pursing development partners for this novel oral anticancer drug candidate."
