there were 2000 pts enrolled in the 2 trial. My guess is that at least 60% of them were moderate. That leaves 800 mild patients, 400 active and 400 PBO. I've read in several reports (for example: http://in.reuters.com/article/2012/08/24/elililly-trial-alzheimer-idINL2E8JO5SY20120824 ), that the majority of patients, roughly two-thirds of them had mild disease. So there were over 1300 mild patients.
