Thanks Dew. There is getting there first as opposed to having the best drug(s). Only time will tell. Having said that, I sure hope that ENTAS doesn't wait too long to get into trials.
PFE did have a PI ready to go for SARS back in 2003. Are we sure this isn't a repurposing of that drug?
EDIT: even if this is a novel drug they could have easily revived the discovery platform and found another in their library, or tweaked the 2003 drug for current virus. i.e. they still had a head start over someone starting totally from scratch
