Brief summary
SHARP-C is an observational cohort study investigating the effect of direct-acting antiviral
(DAA) therapy and reinfection in people with chronic hepatitis C virus (HCV) and recent
injecting drug use. A prospective, observational cohort design will be used to enrol patients
attending tertiary drug and alcohol and primary health care services.

Participants will be prescribed a direct-acting HCV medication as per the standard of care.
The on treatment phase will vary dependent on the type of a direct-acting antiviral
prescribed as per the standard of care. Once patients have completed their treatment course
they will be followed up every 3 months for up to 3 years following the end of treatment

The study will aim to evaluate the incidence of HCV reinfection following successful DAA
treatment over the three years of follow up. The study will also evaluate the proportion of
patients with undetectable HCV RNA at 12 weeks post end of treatment (SVR12) with
direct-acting anti-viral HCV therapy.
