Brief Summary:
Hepatitis B virus (HBV) leads to life-threatening disease like liver failure and liver cancer. For most, a cure is unattainable as current HBV antiviral therapy (using nucleoside analogues) are not able to clear the virus from their liver. While HBV treatments are typically administered alone (monotherapy), this study will explore the use of Ribavirin in combination with standard therapy to enhance current treatment regimens. Ribavirin is commonly used to treat Hepatitis C Virus (HCV) but there is evidence that Ribavirin also induces immune effects that are beneficial in HBV treatment. The aim of this study is to determine whether combination of Ribavirin and a nucleoside analog is more effective compared to nucleoside analog treatment alone. Enrolled patients will be followed for treatment response according to standard clinical and virological tests, as well as immune response to HBV. Our ultimate goal is to find a more effective treatment and improve health outcomes for persons living with HBV.

Arm Intervention/treatment
Experimental: Group 1
Tenofovir (TDF) 300 mg po once a day (OD)
Drug: Tenofovir
Tenofovir as per standard of care

Active Comparator: Group 2
Tenofovir 300 mg po OD + Ribavirin 400 mg twice a day (BID) if <70kg / 600 mg every (q) in the morning (AM) and 400 mg q in the evening (PM) if ≥70kg
Drug: Ribavirin
Ribavirin will be added to the standard of care treatment (tenofovir) regime for 24 weeks.

Drug: Tenofovir
Tenofovir as per standard of care




Primary Outcome Measures :
  1. The Decline of Participants Serum HBV DNA values for both study arms at each study. [ Time Frame: 24 weeks ]
    The absolute decline in HBV DNA and quantitative HBsAg titre will be compared with baseline level at each study visit overall and between study arms (with or without RBV).


Secondary Outcome Measures :
  1. Fibroscan score [ Time Frame: 24 weeks ]
    Individual fibroscan scores pre and post treatment for each group, using fibrosis scores calculated in kilopascal F0 representing no fibrosis and F4 value indicating cirrhosis.

  2. Liver enzyme values [ Time Frame: 24 weeks ]
    Participants individual reduction in liver enzymes at each visit.

  3. Number of participants with treatment related adverse events as assessed by CTCAE v4.0. [ Time Frame: 28 weeks ]
    Safety profile of TDF plus Ribavirin regime
