"Patients treated with a telaprevir-based regimen, who had early HCV RNA undetectability, had higher sustained viral response rates......Among telapravir-treated people with undetectable HCV RNA after 1 week of therapy, 90% attained a sustained virologic response (SVR, undetectable HCV RNA 6 months after treatment ends), if undetectable at week 2 83% achieved SVR, and if undetectable at week 4 77% achieved SVR."
