Our biotech speculative play Dendreon (DNDN) today revealed the details of the results of their IMPACT Phase 3 trial of Provenge at the American Urological Association’s annual meeting in Chicago and…they look great!
Provenge reduced the risk of death from prostate cancer by 22.5%—comparing the Provenge arm of the trial with the placebo arm—which beat the 22% bogey which had been set by the FDA in order to prove that the survival advantage was real. Provenge also extended median survival by 4.1 months compared to the placebo (25.8 months versus 21.7 months) and improved three-year survival by 38% compared to the placebo (31.7% versus 23.0%).
The results were revealed at 2pm EDT; the stock was halted at 1:27pm (the timestamps in the table below reflect CDT) after trading became disorderly, with the price of the stock dropping from $24 to $7.60 in the space of 74 seconds on huge volume. About 20% of the outstanding shares are sold short, so an attack by shorts to drive down the share price prior to the news release might have been the cause. Here is a transcript of trades of 5000 shares or higher for that time span (welcome to the thrills of speculation in individual stocks):

If the stock opens again today—it is still halted pending the completion of the Dendreon presentation at the AUA meeing—it will be interesting to see where it settles. The company has scheduled a conference call to discuss the results at 1730 EDT today. If there is anything interesting to report, we will add a comment to this post.
