Note that the base post in this thread contained some questionable assertions by you and dewophile based on the failure of a two-drug oral regimen from BMY.
a failure of 2 drug regimen does not mean 3 or 4 drugs won't work, but it certainly lowers the odds of 2 drugs working (remember roche also was going to toy with dropping components of SOC in 2 drug regiments in the INFORM trials). at a minimum this means a delay in achieving all-DAA therapies (if any do prove viable)
