Yes, IMO. I noted in #msg-81414058 that the SAPHIRE-III and -IV studies are +/- ribavirin and lack a traditional control arm, while the SAPHIRE-I and -II studies have placebo control arms (with deferred treatment on non-placebo regimens).
It’s the totality of ABT’s phase-3 program in genotype-1 HCV that you should be critiquing, not one or two trials in isolation.
