Summary
Brief summary (as posted)
This is an independent optional sub-study parallel to TARGET-HCC (NCT02954094). The purpose of Direct-Acting Antiviral-Post Authorization Safety Study (DAA-PASS) is to investigate the impact of exposure to direct-acting antivirals (DAAs) on early recurrence of hepatocellular carcinoma (HCC) in hepatitis C virus (HCV)-infected patients following successful HCC treatment interventions.

- Prospective
- description
- The prospective DAA-PASS cohort will include a subset of HCV RNA positive participants in the TARGET-HCC study who meet entry criteria including hepatitis C (with no prior history of DAA therapy) and newly diagnosed Barcelona Clinic Liver Cancer (BCLC) Stage A HCC. Participants will be enrolled in the countries participating in TARGET-HCC which will include: United States (US), France, Germany, Italy, and Spain.
- label
- Historical
- description
- The historical cohort will be derived from the ITA.LI.CA database, which includes data on all consecutive patients with HCC who were managed within participating centers in Italy. The historical cohort will include patients from the ITA.LI.CA database who have active HCV infection who were not treated for HCV (IFN-based or DAA-based regimens) during the followup period, with initial HCC diagnosis BCLC Stage A, and subsequent successful treatment of HCC with curative therapy.
