Australian Trial in Acute Hepatitis C Recall Study (ATAHC Recall)

September 29, 2014 updated by: Kirby Institute

Long-term Outcomes Following Treatment of Recently Acquired Hepatitis C Virus Infection.

A single long-term follow up assessment of an established multi-centre, prospective longitudinal cohort study of patients for clinical, psychosocial, immunovirological outcomes 4 to 8 years after previous treatment for recently acquired hepatitis C virus infection.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The study aims are:

  1. To evaluate the effect of successful prior treatment or spontaneous clearance of recently acquired HCV infection on long-term quality of life, social functioning, injecting behaviour, mental health and liver health.
  2. To assess the incidence of HCV re-infection following prior treatment induced clearance or spontaneous clearance of recently acquired chronic HCV infection.
  3. To determine predictors of HCV re-infection following recently acquired HCV infection treatment.
  4. To determine frequency and predictors of new mixed and superinfections in ATAHC subjects with persistent viraemia.
  5. To add to a tissue repository of serum and PBMCs from well-characterised patients treated for recently acquired HCV infection to allow future examination of the role of other variables that may potentially impact on the prognosis and outcomes of early HCV treatment.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

16 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

An anticipated 60 participants will be recruited from 3 study sites: St Vincent's Hospital, Sydney; The Alfred Hospital, Melbourne; Royal Adelaide Hospital, Adelaide.

Description

Inclusion Criteria:

  • Previous enrolment in the Australian Trial of Acute Hepatitis C Virus Infection (ATAHC) Study.
  • Provision of written, informed consent.

Exclusion Criteria:

  • In the opinion of the investigator that the patient is not able to provide informed consent.
  • Inability or unwillingness to comply with study collection requirements.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Long-term effects of HCV clearance
Time Frame: 4 to 8 years from initial infection
Health related quality of life (measured by SF-12) Social functioning (measured by OTI survey) Injecting behaviour Mental health (measured by DASS and MINI) Liver health (measured by FibroScan and biochemical markers)
4 to 8 years from initial infection

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Incidence of HCV re-infection
Time Frame: 4 to 8 years from initial infection
Rate of HCV RNA positivity in patients previously HCV RNA negative.
4 to 8 years from initial infection

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Predictors of HCV re-infection
Time Frame: 4 to 8 years from initial infection
Associations of HCV re-infection in those with HCV RNA positivity who were previously HCV RNA negative.
4 to 8 years from initial infection
Incidence and predictors of HCV mixed and superinfections in those with persistent viraemia.
Time Frame: 4 to 8 years from initial infection
Rate (or proportion over average years of follow-up) of new mixed HCV RNA infections in those with persistent viraemia and no prior evidence of multiple HCV infection.
4 to 8 years from initial infection
Collection of specimens for future immunological or virological research.
Time Frame: 4 to 8 years from initial infection
Stored serum and peripheral blood mononuclear cells.
4 to 8 years from initial infection

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
