Study summary

The main aim of this study is to test in the Icelandic population the hypothesis that a nationwide treatment program which offers effective treatment to all known cases of Hepatitis C with the aim of halting HCV (Hepatitis C virus) transmission will lead to a reduction in incidence and disease burden associated with chronic HCV infection.

Read the detailed description

In Iceland, a nationwide effort is planned where all patients with HCV infection will be offered treatment using direct acting antiviral agents. The aim of the initiative, besides offering cure to patients, is to substantially reduce domestic transmission of HCV and thereby lower the incidence. Ultimately, with these intense efforts the long-term complications of chronic HCV infection could potentially be nearly eliminated. In Iceland, there is mandatory reporting of all new cases of hepatitis C to the State Epidemiologist.

In the study, short term and long term outcomes of this initiative will be investigated. In an initial treatment phase which will last for up to three years, all patients diagnosed with hepatitis C in Iceland will be offered treatment with direct acting antiviral agents. Virological response rate and compliance will be monitored. Long term, the incidence of HCV infection acquired in Iceland will be monitored for up to 15 years, and the incidence rates of cirrhosis and hepatocellular carcinoma due to HCV will be monitored for up to 15 years.

Inclusion criteria

  • positive subjects 18 years and older, living in Iceland and covered by the Icelandic Health Insurance.

Exclusion criteria

Exclusion Criteria:

  • Age under 18 years
  • Inability to sign .
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Incidence of transmission of HCV in Iceland

    Time frame: Measured annually for up to 15 years

Secondary outcomes

  1. Incidence of cirrhosis and hepatocellular carcinoma in Iceland

    Time frame: Measured annually for up to 15 years

  2. Sustained virological response rate (SVR) to treatment with antiviral agents as measured by negative HCV RNA 12 weeks post treatment
