ABBV/ENTA—Is this a non-issue for GT4, or GT1b in Japan?
Non-issue because ABBV/ENTA’s approved regimens for GT4 patients (Technivie) and GT1b patients in Japan (Viekirax) do not contain Dasabuvir and hence are already dosed qD.
It is not uncommon that ribavirin dosing can be reduced due to AE's. Mine was cut in half, from 1200mg to 600mg (6 pills to 3 pills) due to anemia… In a dose reduction scenario, one could [take ribavirin] just once per day.
A valid point. Ribavirin is generally dosed BID for tolerability, not for efficacy.
