It looks like the Wall Street Journal is trying to bring the share price down. I wonder why? Maybe someone wants some cheap shares before the big news comes out.
I'm not sure this article will affect the share price much. There's not a whole lot of truth to it. As a matter of fact, it's quite comical.
Tysabri May Be Linked
To Added Side Effects

The multiple-sclerosis drug Tysabri, which was withdrawn from the market this year, could be linked to new serious side effects, according to an analyst's report.
Through a Freedom of Information request, Steven Harr, of Morgan Stanley, obtained a list of adverse-events reports made to the U.S. Food and Drug Administration related to Tysabri.
Following an analysis of the data, he issued a note Thursday describing adverse-event reports in which a number of Tysabri patients died of rare infections. "We're not trying to put a death knell on Tysabri, but there are signals in there that something's going on. It's important for patients and investors to know," Mr. Harr said in an interview.
A spokesman for Biogen Idec Inc., of Cambridge, Mass., which manufactures the drug along with Elan Corp., of Dublin, dismissed Mr. Harr's report. The spokesman said Biogen and Elan had performed a detailed safety analysis of the drug and found no statistically significant differences between serious adverse events with patients given Tysabri and patients given a placebo in several clinical trials.
"We have an enormous amount of information in our hands," the spokesman said. "The [adverse events] database is a limited tool." Biogen and Elan said this month they hope to get the drug back on the market.
Leonore Gelb, an FDA spokeswoman, said the agency declined to comment on the analyst's report.
Tysabri was taken off the market on Feb. 28 after a patient contracted a rare brain infection called progressive multifocal leukoencephalopathy, or PML. Two other cases of PML subsequently have been confirmed by the drug's manufacturers. Out of those three cases, there are two confirmed deaths. It is suspected that the reason patients get PML is because Tysabri suppresses the immune system.
The analyst's report describes seven non-PML deaths in patients taking Tysabri that "appear to be related to immunosupression." One death was owing to pneumocystis pneumonia, an infection that only patients with severely debilitated immune systems get; another was because of herpes encephalitis, a very rare infection of the central nervous system, and four other deaths were possibly caused by "sepsis," an uncontrolled infection that spreads through the body.
The report mentioned that the FDA database contained "numerous" accounts of serious, nonfatal infections that "suggest again that the toll from Tysabri extends beyond PML."
Despite the possible new side effects, Mr. Harr said Tysabri has a good chance of returning to the market. Its efficacy is "so compelling" in multiple sclerosis that doctors are likely to want to prescribe it for their sickest patients even if the risk for immune problems is higher.
At 4 p.m. Friday in composite trading on the Nasdaq Stock Market, Biogen shares edged up 13 cents to $41.05 each.
