a little late on the PFE / INCY JAK debate, but here goes. PFE med, BID PO dosing: ACR20: 53% ACR50: 35% ACR70: 22% (previous P2 data: 66/37/20 for ACR 20/50/70 respectively - the P3 numbers are actually worse) INCY P2a data, once daily PO dosing: ACR20: 72% ACR50: 44% ACR70: 30% INCY & LLY have a better mousetrap. Too bad INCY only gets 20-30% royalties. links somewhere in here: http://boards.fool.com/incy-re-eval-29468832.aspx
