OT ENMD Father of angiogenesis sees bright future for tumor choking drugs By Mara Bovsun 02/21/2000 Biotechnology Newswatch Page 11 (Copyright 2000 McGraw-Hill, Inc.) Drugs that cut off a tumor's blood supply will one day turn cancer from a raging killer to a controllable chronic condition, said the father of the field of angiogenesis at a major biotechnology meeting in New York City last week. Doctors in the future will have several angiogenesis inhibitors to give in sequence, in combination or with other therapies to keep tumors from recruiting blood vessels needed to grow and spread, Dr. Moses Judah Folkman told an audience at the annual CEO and Investor conference sponsored by the Biotechnology Industry Organization. This will leave plenty of room for many companies to bring products to market without fear that competitors will crowd them out. ``If physicians had 10 angiogenesis inhibitors today you couldn't keep up with the demand,' Folkman said. Also, abnormal angiogenesis plays a role in at least 26 diseases from macular degeneration to psoriasis to heart disease and arthritis. Folkman also says angiogenesis agents won't prevent doctors from using other therapies, including chemotherapy, radiation, immunotherapy and other new anti-cancer strategies under development at biotechnology companies. ``Angiogenesis inhibitors are not mutually exclusive with other therapies,' he said. Folkman praised the work of the small 85-employee biotechnology company, Entremed Inc., for bringing Endostatin and Angiostatin to the clinic. Trials of Endostatin started in October, and Angiostatin studies are scheduled to start in two weeks, said John Holaday, Entremed 's CEO. Holaday told BTNW that once the drugs are tested as single agents in the initial safety trials, scientists are planning in the Phase II studies to look at the combination that eradicated tumors in mice. These were the best animal study results ever seen with a cancer fighting drug, and they fueled a market and patient frenzy after the treatment was lauded as the cure for cancer in a front-page New York Times article in May 1998. The article quoted Nobel laureate James Watson as saying that Folkman ``is going to cure cancer in two years.' Watson later denied making the comment, and Folkman himself found the reaction to the story troubling. He told one reporter for Newsweek that mouse experiments have no place on the front page of the New York Times. The excitement cooled even more when it became clear that these the drugs were so hard to make that scientists might never cook up batches large enough for experiments on humans. But, since then, EntreMed has worked out the manufacturing glitches. At the meeting, Folkman said that thanks to Entremed 's persistence, scientists will now have the opportunity to put the compounds to the critical human tests. Endostatin trials are progressing well, and Folkman said they have been ``very encouraging' to the oncologists involved in the work. At the meeting, EntreMed , which is investigating other drugs and anti-angiogenesis vaccines, was among several companies with products for cancer in development. Some of the others were: -- Celgene Corp., a 146-employee company in Warren, N.J., is testing thalidomide in a variety of cancers. The company is also investigating thalidomide analogues -- Immunomodulatory Drugs or IMiDs -- that retain the drug's angiogenic properties with fewer side effects. The company says initial Phase I studies of its lead IMiDs was completed late last year, and results will be released soon. The company has another class of drugs -- selective cytokine inhibitory factors, also called SelCIDs -- that modulate TNF-alpha. The lead SelCID is in a Phase II study against Crohn's. -- Oxigene, Inc., of Stockholm, which has created an anti-vascular targeting agent. -- Aeterna Laboratories, Inc., a Quebec City-based biotechnology company, has a drug -- AE-941/Neovostat -- that inhibits matrix metalloproteinases and blocks the VEGF-receptor. The company is investigated the drug in non-small-cell lung cancer and renal cell carcinoma, as well as in psoriasis. NOTE-thalidomide was licensed to Celgene by ENMD since they each had use patents and orphan drug designation for different indications. ENMD gets a percent of revenue from sales for any indication from Celgene Marc
