EntreMed Initiates Combination Phase 2 Clinical Trial With Panzem(R) NCD in Carcinoid Cancer

Multi-Site Study Combines Panzem(R) NCD With Avastin(R)

ROCKVILLE, Md., May 15 (HSMN NewsFeed) -- EntreMed, Inc. (Nasdaq: ENMD ), a clinical-stage pharmaceutical company developing therapeutics for the treatment of cancer and inflammatory diseases, today announced that it has commenced a Phase 2 clinical trial to evaluate the safety and efficacy of its lead clinical-stage drug candidate, Panzem® NCD, in combination with Avastin® (bevacizumab) in patients with locally advanced or metastatic carcinoid tumors. The study will be coordinated by Boston's Dana-Farber/Partners Cancer Care (DFPCC), a collaboration among The Brigham and Women's Hospital, Inc., Dana-Farber Cancer Institute, Massachusetts General Hospital, and the Beth Israel Deaconess Medical Center (BIDMC). The study sites include the Dana-Farber Cancer Institute, Massachusetts General Hospital, and Beth Israel Deaconess Medical Center and will be conducted under the direction of Matthew Kulke, M.D. as principal investigator.

Panzem® (2ME2) is an orally-active small molecule that attacks tumor cells through multiple mechanisms of action and has antiangiogenic activity. Panzem® NCD, a liquid nanocrystal formulation of 2ME2, can attack tumors on multiple fronts -- directly by disrupting microtubules, an intracellular matrix necessary for the rapid division of cancer cells (mitosis), by inducing programmed cell death (apoptosis), and by blocking blood vessels that feed tumors (angiogenesis inhibition). Recent Phase 1b studies with Panzem® NCD have shown that the pharmacokinetic target for antitumor activity was achieved and, additionally, that Panzem® NCD has an acceptable toxicity profile at the therapeutic dose. Panzem® NCD is currently in a Phase 2 clinical trial for brain cancer and a clinical trial in combination with Taxol® in metastatic breast cancer, both being conducted at the Duke University Medical Center.

"Patients with metastatic carcinoid tumors have very few effective treatment options. Combination chemotherapy, when used, generally results in a response rate of 10-15%. We believe that combining two agents with antiangiogenic activity represents a unique approach to treatment, and may produce higher response rates than combination chemotherapy or either antiangiogenic agent alone. Novel, effective therapies are needed to improve the outcomes for these patients," said Carolyn F. Sidor, M.D., M.B.A., EntreMed's Vice President and Chief Medical Officer.

Dr. Sidor further commented, "This clinical trial represents our second Phase 2 study for Panzem® NCD, and our first Phase 2 clinical trial in combination with an approved antiangiogenic agent. We look forward to working with the Dana-Farber/Partners Cancer Care team on this important study."

About Carcinoid Tumors

Carcinoids are tumors of neuroendocrine origin. Approximately 85% of carcinoid tumors develop in the gastrointestinal tract between the stomach and the rectum. Approximately half of these originate in the appendix, and may metastasize to the liver, while the remaining half develop in the intestine, rectum and lung. Approximately 6,000-7,000 cases of carcinoid cancer are diagnosed in the U.S. annually and their incidence has been increasing over the past 30 years. It is common for more than one tumor to develop in the small intestine and the presence of a carcinoid tumor increases the probability of other cancers in the digestive system.

Carcinoid tumors often release certain hormones into the bloodstream that cause symptoms such as facial flushing, wheezing, diarrhea, and a fast heartbeat. These symptoms are grouped together and called the "carcinoid syndrome." Carcinoid tumors can release hormonally active peptides into the blood that cause symptoms throughout the body, as contrasted with other tumor types that produce symptoms at the site of the primary tumor or its metastases. Chemotherapy may be indicated in patients with aggressive tumors, progressive liver metastases, partial or complete intestinal obstruction, or severe symptoms uncontrollable by other treatment methods. Carcinoid tumors tend to be over-represented in certain populations, suggesting a genetic component in the development of the disease.
