HBV/HCV Co-infection Clinical Trial
Official title:
Role of Nucleoside Analogue in Preventing Clinical Reactivation of HBV in HCV/HBV Co-infected Patients Receiving DAA Therapy for Chronic Hepatitis C
HBV reactivation is common in HCV/HBV coinfected patients receiving DAA therapy for chronic hepatitis C. How to prevent HBV reactivation remains unclear. In this trial, we aim to investigate whether prophylactic nucleos(t)ide analogue (NUC) at the start of DAA could prevent HBV reactivation or not. And whether prolonged NUC prophylaxis (24 weeks) would be better than 12-week prophylaxis. This will be a three-arm, open-label, randomized, active controlled, study. Totally, 60 HBV/HCV co-infected treatment-naïve or treatment-experienced patients without decompensated liver cirrhosis will be included in this study. Group 1 patients (n=20) will receive 12-week ETV from the start of DAA therapy. Group 2 patients (n=20) will receive 24-week ETV from the start of DAA till 12 weeks after end of DAA. Group 3 patients (n=20) will not receive ETV during the period of DAA and will serve as controls. The rate of HBV reactivation and clinical reactivation will be compared among 3 groups of patients. Expected outcomes: The rate of HBV reactivation and clinical reactivation will be lower in the ETV prophylaxis group, and will be the lowest in the group receiving 24-week ETV prophylaxis.
We will determine the incidence of virologic and clinical reactivation of HBV during DAA
treatment for CHC, in two prophylactic groups versus control group. We will also examine
whether extending the duration of prophylactic NUC would be more beneficial than the 3-month
prophylaxis regimen.
Patients with the following criteria will be enrolled: age ≥20 years; anti-HCV positive and
HCV RNA >1000 IU/ml; any HCV genotype; all received 12 weeks of DAA treatment; treatment
naïve or experienced of pegylated interferon/ribavirin; concurrent HBV infection which is
defined by positive HBsAg for at least 6 months. Patients with the following criteria will be
excluded: history of treatment regimen that included any kind of direct antiviral agents;
presence of other etiology of chronic hepatitis including HIV, autoimmune hepatitis, NASH,
etc; uncontrolled diabetes mellitus (Hba1c >8.5); current evidence or suspicion of
malignancy; severe cardiovascular or other severe comorbid diseases; autoimmune disorders;
presence of liver cirrhosis clinically or pathologically; any one of following hematology or
biochemical or clinical abnormalities: AST/ALT >10x ULN, Albumin <3.5g/dL, Bilirubin
>2.5mg/dL, eGFR <30 ml/min/1.73m2, prothrombin time prolongation >4 sec or INR >1.7, platelet
count <100 x 103 uL, and history or presence of ascites or hepatic encephalopathy;
child-bearing age women without the willing to contraceptive control; and pregnant women or
lactating women.
Briefly, 60 HCV/HBV coinfected patients will be enrolled and randomized to receive 12-week
DAA regimen for reimbursed for the the treatment of patients with CHC in Taiwan.
Entecavir (0.5mg; ETV) 1 # daily will be used in the prophylactic group. Group 1 patients
(n=20) will receive 12-week ETV from the start of DAA therapy. Group 2 patients (n=20) will
receive 24-week ETV from the start of DAA till 12 weeks after end of DAA. Group 3 patients
(n=20) will not receive ETV during the period of DAA and serve as controls. The rate of HBV
reactivation and clinical reactivation will be compared among 3 groups of patients.
The primary endpoint will be the incidence of virologic and clinical reactivation of HBV
during DAA treatment for CHC. Secondary objectives include the rate of HBV virologic and
clinical reactivation between 12-week versus 24-week entecavir (ETV) prophylaxis during and
after DAA treatment; the profiles of serum HBV DNA/qHBsAg during and after DAA treatment; and
sustained virological response at post-DAA treatment 12 weeks (SVR12).
The data will be expressed as percentages for category variables and as mean +- standard
deviation for continuous variables. Category variables will be evaluated by Chi-square test
or Fisher exact test. Student's t test or Mann-Whitney U test will be applied for comparison
of the continuous variables. Multivariate analysis will be used to identify factors that are
associated with HBV reactivation. A p value less than 0.05 is considered to be significant.
