Oh Yeah, Now That You Mention It, They're Dead
The overhyped nature of stem cell therapies is a topic that's come up here several times. In the latest developments, Pluristem, Inc., is threatening to sue Bloomberg New for their recent report, titled "Girl Dies As Pluristem Sells On Gains With Miracle Cells". Gosh, it's hard to see why the company would take exception to a headline like that, but here's how the piece leads off, in case things weren't clear:
Pluristem Therapeutics Inc.’s (PSTI) stock doubled in Nasdaq trading from May through September, helped by three news releases announcing that patients’ lives had been saved by injections of the company’s experimental stem cells.
After the stock soared on the positive news, two top executives profited by selling shares at the highest price in more than four years as part of a pre-determined program. When the first of those patients, a 7-year-old girl with a bone- marrow disease, died four months after the company said her life had been saved, Pluristem was silent. The company raised $34 million selling shares a week later.
Not so good. But as that link in the first paragraph shows, Pluristem's response has not cleared things up very much. In the same press release in which they demanded a correction from Bloombert, they revealed that another of their three initial patients had also died after four months, which also had not been announced before. The earlier press releases for all three patients are well-stocked with phrases like "medical miracle" and "life-saving". As long as this sort of thing is going on, the stem cell field will continue to have problems.
Update: interestingly, this post seems to have brought a lot of Pluristem's stock market fans flocking. And I mean this in the best possible way, but their appearance here does not inspire confidence.
