So far only repurposed meds are in trials as far as I know. remdesivir (inhaled), pfizer, merck. Even if there is some efficacy there is going to be room for improvement IMO for a tailor made antiviral. I have no idea who is where in development, but ENTA has as good a chance as any based on their track record IMO. The fact the US govt is ready to put resources behind it could be bullish and is a tacit acknowledgement that there is going to be room for a DAA on top of vaccines good luck w VXRT
