EntreMed Commences Panzem(R) NCD Phase 2 Study in Prostate Cancer

ROCKVILLE, Md., Sept. 12 (HSMN NewsFeed) -- EntreMed, Inc. (Nasdaq: ENMD ), a clinical-stage pharmaceutical company developing therapeutics for the treatment of cancer and inflammatory diseases, today announced commencement of a multi-center Phase 2 study with its lead clinical- stage drug candidate, Panzem® NCD (2ME2 or 2-methoxyestradiol), in patients with hormone-refractory prostate cancer (HRPC). Initially, the study will be conducted by the University of Wisconsin Comprehensive Cancer Center, as a member of the Prostate Cancer Clinical Trial Consortium, with additional sites joining during the third quarter. Dr. Glenn Liu, Assistant Professor of Medicine, University of Wisconsin, will serve as the principal investigator.

Patients with evidence of progressive metastatic disease or known metastatic disease and rising PSA, during or after treatment with a taxane- based regimen, are expected to be enrolled in the study. The purpose of the study will be to assess the antitumor activity, safety, and pharmacokinetics of Panzem® NCD in patients with HRPC. This study will expand the results obtained to date on the use of Panzem® in men with HRPC.

Dr. Liu commented on commencement of the study, "A major problem with assessing treatment benefit in prostate cancer is the difficulty of evaluating responses in patients with bony metastasis. In these patients, the utility of measuring a PSA response may or may not be clinically meaningful using a novel agent like Panzem® NCD. For this study, we chose to assess a valuable clinical endpoint (progression-free survival), as well as a pharmacodynamic endpoint using current imaging technology. This will also allow us to fully evaluate the benefits of potential new anticancer agents like Panzem® NCD."

Carolyn F. Sidor, M.D., M.B.A., EntreMed Vice President and Chief Medical Officer, commented, "HRPC has been a focus of our development plan for Panzem® and working with the Prostate Cancer Clinical Trial Consortium allows us to continue this effort at multiple sites well-known for their expertise in prostate cancer trials. Very few options exist for patients with taxane-refractory HRPC and most chemotherapeutics are associated with considerable toxicity. Our goal is to provide patients with an option that may stabilize their disease without significant side effects."

About Prostate Cancer

Prostate cancer is one of the most common cancers in men and accounts for about 10% of cancer-related deaths in men. The American Cancer Society estimates that approximately 230,000 new cases will be diagnosed in the United States in 2006, resulting in approximately 27,000 deaths. Chances of developing prostate cancer increase in men over 50 years of age. Prostate cancer occurs when cells within the prostate gland grow uncontrollably, creating small tumors.
