It is intersting that with the regiment including sofosbuvir, Detected at EOT still have higher cure rate
"There must be other reasons to explain the high SVR," Guedj said. "We think most of the [newly produced] virus may be uninfectious...treatment may have the effect of replacing a working replication complex with a defective replication complex, which explains how most patients could clear the virus in 6 weeks."
"Low negative predictive values of HCV RNA at week 4 underscore the importance of continued therapy for patients who fail to achieve undetectable levels of HCV RNA early on during treatment because the likelihood of achieving SVR12 is still high," the researchers concluded. "Contrary to past experience with interferon-containing treatments, the presence of detectable HCV RNA at EOT [end of treatment] is not predictive of relapse in these studies."

An uninfectious virus may only explain these data of this person:
