Outcome Measures

Primary Outcomes (2)

  • Proportion of participants who experience virological breakthrough

    Virological breakthrough is defined as 1 logIU/ml increase during and/or post DAAs treatment for the baseline or nadir.

    From the commencement of DAAs treatment to 12 weeks post DAAs treatment

  • Proportion of participants who experience virological rebound

    Virological rebound is defined as 2 logIU/ml increase during and/or post DAAs treatment for the baseline or nadir.

    From the commencement of DAAs treatment to 12 weeks post DAAs treatment

Secondary Outcomes (1)

  • Proportion of participant who experience biochemical rebound

    From the commencement of DAAs treatment to 12 weeks post DAAs treatment

Other Outcomes (1)

  • Proportion of participant who experience liver failure

    From the commencement of DAAs treatment to 12 weeks post DAAs treatment

Study Arms (2)

Prophylactic/Early anti-HBV treatment

ACTIVE COMPARATOR

HCV/HBV co-infection patients in this arm will receive nucleos(t)ides analog (Entecavir or Tenofovir disoproxil fumarate) for the treatment of hepatitis B infection before or at the commencement of direct anti-HCV treatment using DAAs (Ledipasvir/Sofosbuvir; or Sofosbuvir and Daclatasvir, or Ombitasvir, Paritaprevir, Ritonavir, Dasabuvir; or Sofosbuvir+Ribavirin). .

Drug: Ledipasvir/SofosbuvirDrug: Sofosbuvir and DaclatasvirDrug: Ombitasvir, Paritaprevir, Ritonavir, DasabuvirDrug: EntecavirDrug: Tenofovir disoproxil

Deferred anti-HBV treatment

EXPERIMENTAL

HCV/HBV co-infection patients in this arm will receive nucleos(t)ides analog (Entecavir or Tenofovir disoproxil fumarate) for the treatment of hepatitis B infection when HBV viral breakthrough occurred during anti-HCV treatment using DAAs (Ledipasvir/Sofosbuvir; or Sofosbuvir and Daclatasvir, or Ombitasvir, Paritaprevir, Ritonavir, Dasabuvir; or Sofosbuvir+Ribavirin).

Drug: Ledipasvir/SofosbuvirDrug: Sofosbuvir and DaclatasvirDrug: Ombitasvir, Paritaprevir, Ritonavir, DasabuvirDrug: EntecavirDrug: Tenofovir disoproxil
