Brief Summary

The aim of the study is to determine if treatment for recently acquired hepatitis C infection (with or without HIV coinfection) can be shortened when treating with the interferon-free therapy sofosbuvir/velpatasvir (SOF/VEL). SOF/VEL is a new treatment for hepatitis C called direct acting antiviral which targets the hepatitis C virus replication cycle and has been shown in phase II studies in chronic HCV to be highly effective (SVR12 \>95%) when given for 12 weeks. Data has shown that treatment can be shortened when treating recently acquired HCV with interferon containing treatments. It is not known whether treatment with SOF/VEL can be shortened. This study aims to find out if treatment for 6 weeks with open-label SOF/VEL is equivalent to treatment for 12 weeks with SOF/VEL in participants with recently acquired hepatitis C infection. The project is a randomised study where both participants and investigators would not find out the treatment duration of the participants until week 6 of treatment.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Undetectable HCV RNA at 12 Weeks Post End of Treatment (SVR12) Following SOF/VEL for 6 Weeks as Compared With 12 Weeks in People With Recent HCV Infection- Among Intention-to-treat (ITT) Population

    To evaluate the proportion of participants with HCV RNA below the level of quantification at 12 weeks post treatment following SOF/VEL for 6 weeks as compared with 12 weeks in people with recent HCV infection- among intention-to-treat (ITT) population The ITT population included all randomized participants, with loss to follow-up deemed treatment failure.

    12 weeks post treatment

Secondary Outcomes (3)

  • Number of Participants With Undetectable HCV RNA at 12 Weeks Post End of Treatment (SVR12) Following SOF/VEL for 6 Weeks as Compared With 12 Weeks in People With Recent HCV Infection- Among Modified Intention-to-treat (ITT) Population

    12 Weeks Post End of Treatment

  • Number of Participants With Undetectable HCV RNA at End of Treatment (ETR) of SOF/VEL for 6 Weeks as Compared With 12 Weeks in People With Recent HCV Infection- Among Intention-to-treat (ITT) Population

    End of treatment - week 6 of the shortened treatment duration arm, and week 12 of the standard treatment duration arm

  • A) i) First anti-HCV Ab or HCV RNA positive within the previous 3 months and ii) Documented anti-HCV Ab negative within the 12 months prior to anti-HCV antibody positive result
  • B) i) First anti-HCV Ab or HCV RNA positive within the previous 3 months and ii) Acute clinical hepatitis \[jaundice or alanine aminotransferase (ALT)\] \> 10 X ULN) within the previous 6 months prior to first positive HCV antibody or HCV RNA, with no other cause of acute hepatitis identifiable
  • C) For cases of recent HCV reinfection the following criteria are required:

You may not qualify if:

  • History of any of the following:

  • Significant drug allergy (such as anaphylaxis or hepatotoxicity).
  • Subject shows evidence of significant liver disease in addition to hepatitis C, which may include but is not limited to drug- or alcohol-related cirrhosis, autoimmune hepatitis, hemochromatosis, Wilson's disease, non-alcoholic steatohepatitis (NASH), or primary biliary cirrhosis
  • Subject has known cirrhosis
  • Any of the following lab parameters at screening:
  • Direct bilirubin \> 1.5 x ULN
  • Platelets \< 50,000/μL
  • Creatinine clearance (CLcr) \< 60 mL/min

Data Sharing

IPD Sharing
Will share

No individual participant data will be shared. The results of the project will be presented at scientific meetings, and published in peer reviewed scientific literature. Sharing of data generated by this project is an essential part of our proposed activities and will be carried out in several different ways. We plan to make our results available to the community of scientists interested in recently acquired hepatitis C, community organisations representing the affected communities and participants. We also welcome collaboration with others who could make use of data and samples.
