EntreMed Presents Data for Phase 2 Study of MKC-1 in Metastatic Breast CancerResults Demonstrate Durable Single Agent Responses
ROCKVILLE, Md., Sept. 10 (HSMN NewsFeed) -- EntreMed, Inc. (Nasdaq: ENMD ), a clinical-stage pharmaceutical company developing therapeutics for the treatment of cancer and inflammatory diseases, today announced the presentation of interim results for its Phase 2 clinical study of MKC-1 in patients with metastatic breast cancer (MBC). The data were presented by EntreMed collaborators during the 2007 Breast Cancer Symposium "Integrating Emerging Science into Clinical Practice," held September 7-8, 2007 in San Francisco, California. Dr. Kathy D. Miller, Associate Professor, Indiana University Cancer Center, Indianapolis, Indiana is the first author.
The Phase 2 single-agent study is being conducted at multiple centers across the United States to evaluate the safety and efficacy of MKC-1 in metastatic breast cancer patients who have failed therapy with anthracyclines and taxanes. Results from the first stage of the single-agent study demonstrate that orally-administered MKC-1 is well-tolerated without evidence of cumulative toxicity in anthracycline/taxane refractory metastatic breast cancer patients. Of the 35 evaluable patients, one complete response (CR), two partial responses (PR), and three stable diseases (SD) of greater than four months were observed. This study has proceeded to the second stage and is continuing to enroll up to 53 evaluable patients to confirm safety and assess the extent of objective responses in this patient population.
MKC-1 is a novel, orally-active, small molecule cell cycle inhibitor with a unique mechanism of action, which involves inhibition of the Akt-mTOR pathway, binding importin-b and tubulin, cell cycle arrest, and apoptosis. MKC-1 arrests mitosis by inhibiting an intracellular target important in cellular trafficking that has been shown to be involved in cell division. MKC- 1 has been shown to inhibit mitotic spindle formation, prevent chromosome segregation in the M-phase of the cell cycle, and induce apoptosis in multiple cell lines, consistent with a mechanism in which MKC-1 blocks the nuclear uptake of proteins essential to cell replication.
Carolyn F. Sidor, M.D., M.B.A., EntreMed's Vice President and Chief Medical Officer, commented on the results, "MKC-1 is showing good antitumor activity in metastatic breast cancer patients who had failed conventional anthracycline and taxane chemotherapy. In addition, the study has passed a second Data Safety Monitoring Board (DSMB) review without any study modification. This study is an important milestone for our MKC-1 clinical development program as it confirms that MKC-1 does have single-agent activity and is well-tolerated by these advanced breast cancer patients. An additional MKC-1 single-agent study is underway in hematological cancers and a combination study is underway with pemetrexed (AlimtaŽ) in non-small cell lung cancer. We plan to evaluate our options for either randomized single- agent or combination studies in breast cancer once this study is complete."

EntreMed, Inc. is a clinical-stage pharmaceutical company developing therapeutic candidates primarily for the treatment of cancer and inflammation. PanzemŽ NCD (2-methoxyestradiol or 2ME2) is currently in multiple Phase 2 clinical trials for cancer. MKC-1, an oral cell-cycle regulator, is in multiple Phase 1 and 2 studies for cancer. ENMD-1198, a novel tubulin-binding agent, is in Phase 1 studies in advanced cancers. PanzemŽ is also in preclinical development for rheumatoid arthritis, and ENMD-2076, a dual-acting Aurora-angiogenesis inhibitor, is in preclinical development for cancer. EntreMed's goal is to develop and commercialize new compounds based on the Company's expertise in angiogenesis, cell-cycle regulation and inflammation -- processes vital to the treatment of cancer and other diseases, such as rheumatoid arthritis.
