Good evening Walter,
Just now got back on the net after a mid-western thunderstorm whacked one of the store computers today. Soon found that most everything was "as usual" at Lake Ligand! I was really surprised to see ENMD halt the slide late last week. I tried to short at 44 on DLJ and didn't get the shares. Kind of frustrating!! Seemed like a no-brainer short, but I thought that about Ktel also(maybe I'm the one with no brains).

Get some rest this weekend,
Hope we have a busy end of May at Lake Ligand ahead of us!
Greg

COMMENTARY: OF MICE, MEN, AND CANCER CURES

This is a cautionary tale about the confusion that can erupt when you mix a powerful newspaper, desperately ill cancer victims, hungry investors looking for the next blockbuster drug, and the word ''cure.''
Last November, Judah Folkman and Michael S. O'Reilly--doctors at Boston Children's Hospital--reported in the science journal Nature that they had discovered two human proteins, called angiostatin and endosta-tin, that eradicated all signs of cancer in mice. The proteins were isolated from the urine of mice that had been given human cancers. The Nature report generated a buzz in the oncology community because it described a treatment that appeared to short-circuit the method by which tumors grow and spread throughout the body.
Since then, EntreMed Inc., a tiny biotech company in Rockville, Md., has been quietly working on a manufacturing process that would create enough of the two proteins to conduct human trials, which they hope to start in a year or two. Many news outlets ran stories about Folkman and O'Reilly's work, including Newsday, CNN, the Associated Press, Consumers Digest, BUSINESS WEEK--and The New York Times. The research has also been discussed at a handful of cancer meetings, the most recent a New York Academy of Sciences symposium on Apr. 28, to which the press was invited.
On the following Sunday, May 3, The New York Times revisited Folkman's discovery. But this time, they gave it the star treatment. The newspaper published a front-page story on angiostatin and endostatin, quoting Nobel laureate James D. Watson, a co-discoverer of DNA, saying that ''Judah [Folkman] is going to cure cancer in two years.''
The story, coming after a week of stock-market frenzy over Pfizer Inc.'s impotence blockbuster Viagra, caused a worldwide sensation. On Monday morning, EntreMed's stock shot up from $12.06 a share to a mind-boggling $85 before closing at $51.81 on May 4. EntreMed's phones were ringing off the hook, and cancer centers around the country were inundated with calls from patients desperate for the new ''life-saving'' drugs.
The only problem: There are no drugs. There may never be any drugs. So far, these proteins have only cured cancer in mice. And it's a long way from success with mice to a cure for humans, cautions Dr. James M. Pluda, senior clinical investigator of the National Cancer Institute's investigational drug branch: ''The field of oncology is littered with the bodies of agents that were the next magic bullet.''
''TAKE-HOME MESSAGE.'' To their credit, EntreMed and Folkman started putting that same message out within a day of the Times story, trying hard to end speculation that they had discovered a cancer cure. ''We're very cautious about that four-letter word,'' EntreMed Chief Executive Officer John W. Holaday said over and over, and the stock dropped to 31 1/8 by May 6. But his cautionary message was still difficult to hear over the public's clamor for the new miracle drug. ''All of a sudden, you pick up the newspaper and see a Nobel laureate saying there's a cure for cancer on the front page,'' says Lehman Brothers Inc. analyst C. Anthony Butler. ''That was the take-home message.''
The message arrived when the public and Wall Street were exquisitely tuned to hints of the next wonder drug. Pfizer's stock has climbed 50% since early this year on expectations of billion-dollar sales for Viagra. In April, the stocks of Zeneca Group PLC and Eli Lilly & Co. scored on news that their designer estrogen drugs, Tamoxifen and Evista, can prevent breast cancer.
But those drugs are already on the market, after numerous clinical trials. Angiostatin and endostatin, like so many promising lab discoveries before them, may never even reach human trials. ''A lot of new investors don't have a very sophisticated understanding of the pitfalls involved in creating new drugs, especially cancer treatments,'' laments Volpe Brown Whelan analyst David M. Steinberg.
Reporters, analysts, and especially Nobel scientists must be far more careful about overhyping so-called cancer cures--particularly ones that are still more theory than reality. Granted, The New York Times published a story a day after its Sunday bombshell cautioning that it will be years, if ever, before the EntreMed treatments are commercially available. But that second-day hand-wringing is cold comfort for the millions of cancer victims whose hopes were raised by a ''miracle cure'' that might never materialize.

Here's more on ENMD's anti-angiogenesis approach:
By Jenifer Joseph
ABCNEWS.com
May 8 - Grace Kelly, a 13-year-old Pekingese with a tangerine-sized tumor in her mouth, was the first dog to undergo the drug treatment that had the cancer community in a frenzy last week.
ÿÿÿÿ The combination of the blood-vessel-growth inhibiting drugs angiostatin and endostatin appears to completely eradicate tumors in mice. So researchers decided last winter to try it on a larger mammal. Has it worked on Kelly?
ÿÿÿÿ Scientists are still trying to figure that out. But so far her experience is a perfect illustration of the enormous hurdles researchers face in determining whether a drug that kills cancer in mice will also work in higher mammals like dogs-or humans.

Dog Days in the Lab
Last February, after chemotherapy and other treatments had failed to shrink her tumor, Kelly began taking daily doses of the canine version of anti-angiogenesis drugs.
ÿÿÿÿOnce a day for 2« months, researcher Dr. Judah Folkman came over from nearby Boston Children's Hospital with Kelly's medicine, stored on ice.
ÿÿÿÿ On the 74th day, however, her doctors halted the treatment. She had developed large, swollen lumps in the areas where the injections were given.
ÿÿÿÿ Dr. Michael Bernstein, Kelly's veterinarian and chief of medicine at Angell Memorial animal hospital in Boston, says they're not sure what the swelling meant. It could have occurred because her body was mounting an immune defense to the drugs rather than absorbing them.
ÿÿÿÿ Meanwhile, the Folkman team has returned to the lab to reformulate the drug combination, and Kelly may undergo another round of treatment.
ÿÿÿÿ Still, Bernstein isn't concerned that the treatment made no visible difference in Kelly's tumor. He points out that she wasn't on the therapy long enough to see a response. In Folkman's study of mice, it took two weeks for tumors to respond to the drugs, and one mouse day equals roughly five dog days.
ÿÿÿÿ"Theoretically it looks beautiful," says Bernstein. "But we don't want to raise false hopes that this is going to work."
ÿÿÿÿ Even if it works, he adds, the cancer-fighting drugs would be under study for a long time before they become commercially available for veterinary oncologists to prescribe.

Vet Visit to the Nuclear Reactor
As dogs and cats live longer, the field of high-tech pet healthcare is expanding by leaps and bounds. And much like their owners, these animals are developing cancer in their geriatric years. As many as 47 percent of all household dogs ultimately die of cancer.
ÿÿÿÿ"We used to think, when a dog gets old, it's silly to go on trying to keep them alive," says Dr. Dave Barbee, radiologist at Washington State University's vet school. "But there are two reasons why we're doing this: Pure cancer research that has human potential is one. The other is that pet owners are demanding it."
ÿÿÿÿ Barbee and his colleagues at WSU are currently testing a treatment called boron neutron capture therapy, in which boron is injected into a dog with a brain tumor. After the boron migrates to the tumor, the dog is placed in front of an invisible particle beam, found only in nuclear reactors. (The dogs are flown to a nuclear reactor facility on Long Island, N.Y., for the treatment.) In the path of the beam, the boron literally explodes, thereby killing the tumor.
ÿÿÿÿ "It's pretty exciting," says Barbee. "Kill the bad guys and leave the normal neighborhood alone."
ÿÿÿÿ So far, they've tested the therapy in about 50 dogs with mixed results. Some don't respond at all. Others, like a 5-year-old lab named Brandy, live well beyond their life expectancy.
ÿÿÿÿ Once dogs contract cancer, they usually live less than a year, but after her brain tumor was zapped with the particle beam, Brandy lived five more years. That more than three decades in human terms.

Gene Therapy Too
It's not easy to translate such success from one species to another, but researchers know that what works in dogs has great potential to work in humans as well. After all, roughly 85 percent of genes found in humans are also found in dogs.
ÿÿÿÿ Based on this knowledge, researchers at the University of Cincinnati's Veterinary Cancer Control Program are developing "direct transfer gene immunotherapy" as a treatment for dogs.
ÿÿÿÿWhen an incompatible human gene is injected into an animal's tumor, its body considers the tumor a foreign object and triggers an immune response.
ÿÿÿÿ The technique is also being explored in human clinical trials.
ÿÿÿÿIf you've never heard of any of these pet-cancer research projects, don't be surprised. Most are kept low-key because of the competitiveness in the field and the financial potential that a proven success could bring.
ÿÿÿÿ And until they're proven to work, standard chemotherapy remains one of the best treatments for a dog with cancer.
