About this study

Official title: Boceprevir-based Triple Therapy to Rescue HCV Genotype 1/HBV Dually Infected Patients Refractory to Peginterferon Plus Ribavirin Combination Therapy

Read the detailed description

Liver disease, especially viral hepatitis, is an important public health issue, which frequent leads to liver cirrhosis, hepatocellular carcinoma (HCC) and liver-related death. Around 340 to 400 million persons are infected with hepatitis B virus (HBV) and 130 to 210 million persons are infected with hepatitis C virus (HCV) worldwide, In Taiwan, the prevalence of HBV infection is 15-20%, and the prevalence of HCV infection is 2-5% in general population. Moreover, there are some HCV-hyperendemic areas in southern Taiwan with anti-HCV prevalence rate of as high as 30-40%.

HBV/HCV dual infections is not uncommon in HBV epidemic areas, such as Southeastern Asia, with a prevalence rate of 1.1% in southern Taiwan. Recent study showed that the risk of HCC incidence is even higher among HBV/HCV co-infected persons than those with HBV or HCV mono-infection, indicating the importance of disease control in this clinical setting.

The PEG-IFN/RBV has been effective in the treatment of HCV-dominant, treatment-naïve patients with HCV/HBV dual infections. For treatment-naive HCV genotype 1 (HCV GT1)/HBV co-infected patients, 48 weeks of peginterferon (PEG-IFN) plus ribavirin (RBV) could achieve an HCV sustained virological response (SVR) rate of 72%, which was comparable to 77% for patients with HCV GT1 monoinfection. For treatment-naive HCV GT2 or GT3 /HBV co-infected patients, 24 weeks of PEG-IFN plus RBV could achieve an HCV SVR rate of 83%, which was comparable to 84% for patients with HCV GT2/3 monoinfection . Furthermore, PEG-IFN plus RBV combination therapy could enhance seroclearance of hepatitis B surface antigen (HBsAg) with an HBsAg loss rate of upto 11%. Nevertheless, there is about 30% of HCV GT1/HBV and 20% of HCV GT2 or 3/HBV co-infected patients refractory to current PEG-IFN/RBV combination therapy, which remains at high risk of HCC and liver-related death.

Boceprevir is an oral antiviral drug, which is NS3/4A protease inhibitor. Boceprevir has been approved for treating HCV GT1 infection by Food and Drug Administration (FDA) on 11 May 2011. For HCV GT1 mono-infected patients who refractory to previous PEG-IFN plus RBV combination therapy, becoprevir combined with PEG-IFN/RBV triple therapy can improve the treatment efficacy. The SVR rate of becoprevir-based triple therapy is about 3 times when compared to patients who received PEG-IFN with RBV dual therapy [14].The investigators , therefore, hypothesize that boceprevir plus PEG-IFN/RBV is effective in treating HCV GT1/HBV dually infected patients who are refractory to previous PEG-IFN/RBV combination therapy.

Questions about this trial

What is this clinical trial studying?

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Mar 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Full Analysis Set Participants Who Received HCV Anti-viral Therapy With Sustained Virological Response (SVR) (time frame: week 24). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02060058, which also lists 16 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Mar 2018.
