SBPH—The Twitter thread you cited is quite technical. I get the issue of nucleoside phosphorylation (e.g. #msg-42396728, #msg-64569966, #msg-64570180); however, my understanding is that the second and third phosphorylation steps are not as finicky as the first, so I might not fully gree with John Tucker's tweets in the thread you referenced.
p.s. I plan to listen to the SBPH CC replay over the weekend.
SBPH addendum: Listened to the webcast and studies the CC slides. I don't see any particular reason to be optimistic about the outcomes of the phase-2b trials (just getting underway) other than in showing Inarigivir could have a place as salvage therapy for patients with nuke resistance. But this is not the big market that other HBV players are pursuing.
