Yes, there are patients at SVR4, SVR12 and one I know of at SVR24 (who sourced research APIs very early on)
I have over 100 patients on generics and all but 3 were VL = 0 at 4 weeks. One was VL = 0 at EOT and the other 2 are pending 6 week load testing (one with VL 47 @ 3.5/52, the other < 15)
Bioequivalence as in pharmacokinetic AUC testing is a cheap hack to avoid doing actual trials when introducing generics.
The actual clinical results on these generics are in line with expectations.
