I undergruppen af patienter med genotype 1 og lav virusmængde (< 600. 000 IU/ ml) som bliver HCV- RNA negative ved behandlingsuge 4 og som stadig er HCV- RNA negative ved uge 24, kan behandlingen enten stoppe efter denne 24 ugers behandlingsperiode eller blive videreført i yderligere 24 uger (dvs. en samlet 48 ugers behandlingsperiode).
