StockDoc, If your premise is 10% mortality then just forget Xoma. The example you want: from 10% to 5% will need about 1000 patients on each group (placebo and bpi). An astonishing feat would be (and a more realistic expectancy in the placebo group): placebo 25% vs bpi 12.5%, a 50% decrease and the actual close to 400 case is enough. Even placebo 20% vs bpi 16% (4% absolute, relative 25% decrease) will be a huge success (number of patients will be in the 600 to 800 range on each group). Please, understand the numbers are educated guessing. I do not have the software to calculate them.at this moment. Xoma go, 2000 patients total must be the goal.
