The outlook for Danoprevir may have dimmed especially given Roche's cuts a little while back but please keep in mind what the title of the event was "Late-stage pipeline event" also there are several studies active so I wouldn't go all out betting Roche partners for another PI with one of your HCV holdings just yet.
If Roche continues with these studies I think the data produced and perhaps more so the competitive HCV landscape at the time will determine the future of the molecule.
