Agreed, and I deleted in the already long post (for the sake of brevity. : ) ) that RBV was used, but probably will NOT be in the picture in the future.
And I also deleted ....remember the Electron trial? 10 genotype 1a null responders treated with only 7977 and RBV. It netted an 11% cure rate. These are little bumps in the road and have since been forgotten, or the fact that it "overpaid" the 11+ billion for some compound; PSI 7977. Wall street was unimpressed, as I recall.
