This observational long-term follow-up study will assess the persistence of direct acting antiviral (DAA) resistant mutations and the durability of sustained virological response in patients with chronic hepatitis C who have participated in a Roche DAA treatment protocol. Up to 5 scheduled monitoring visits for blood sampling during an observational period of up to 36 months.

Primary Outcome Measures:
  • Persistence of DAA-associated resistant mutations following discontinuation of DAA therapy [ Time Frame: 18 months ] [ Designated as safety issue: No ]
  • Durability of sustained virological response (SVR-24), defined as undetectable HCV RNA measured by Roche COBAS TaqMan HCV Test [ Time Frame: 36 months ] [ Designated as safety issue: No ]
  • Collecting of serum specimens from patients with partial viral response or viral load rebound of viral response while on RO5024048 treatment, to monitor for resistance mutations in viral RNA [ Time Frame: 18 months ] [ Designated as safety issue: No ]

Biospecimen Retention:   None Retained
Serum specimens collected from patients with partial viral response or viral load rebound of viral response to monitor for resistance mutations in viral RNA

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Chronic hepatitis C patients having received direct acting antiviral treatment in donor protocol

Inclusion Criteria:

  • adult patients, >/=18 years of age
  • chronic hepatitis C
  • participation in Roche DAA treatment protocol for CHC infection
  • DAA-associated resistant mutations persisting through to last evaluation in donor protocol , or partial viral response or viral load rebound while on RO5024048 treatment, or sustained virological response >/= 20 weeks after last dose of study medication in donor study

Exclusion Criteria:

  • For patients participating in DAA resistance monitoring: Initiation of treatment after participation in the donor protocol for which there is evidence of cross-resistance to donor protocol DAA
  • For patients participating in DAA SVR durability: Treatment with any anti-HVC therapy since establishing SVR in the donor study
