Yup. The SAE differential is the exciting part. It will be interesting to see which of the 3 arms in the pivotal is best.
David, any thoughts on ARRY's ARRY-380 (#msg-55080837)? The drug is obviously well behind T-DM1 and is at a very early stage, but it looks quite interesting to me and looks active to me based on the early data. Perhaps it could ultimately be combined with T-DM1 as well (#msg-55159001).
