INGN

I vote for your third option. New data or not, there’s no way that the historical RR on second-line chemotherapy changed from 20-30% last June to 5-25% now on an apples-to-apples basis. (If anything, one would expect the RR to go up over time, not down.)
Okay, maybe I'm just misreading--I admit I haven't been following the INGN story, but when they say "historical response rate" I assume the data come from the literature, not from any of their trials. So option 1 (digging up new data) or option 2 (data brought to their attention) are more likely.
