Yes. But first is still first. A functional cure (even a 50% cure) and being first would have it's benefits.
I'm not up on who else has an effective agent for the surface antigen, but such an agent and EDP-514 could achieve a functional cure ...or..... it might prove/suggest what else is missing for a functional HBV cure.
RE: your post on "pretty modest"; the volume isn't that compelling. I held, although I thought the drop could easily be in the 10% range.
I'm not saying either party can or should. I'm just wondering what the next move will be and thinking of options- while not knowing what Enanta has in development- or their competitors.
