Ledipasvir/Sofosbuvir for Hepatitis B Virus Infection (APOSTLE)
A Phase II Open-Label Study of Ledipasvir/Sofosbuvir for 12 Weeks in Subjects With Hepatitis B Virus Infection
The goals of therapy against chronic hepatitis B are to decrease the morbidity and mortality related to chronic HBV infection. Currently available antiviral therapy can suppress viral replication but only a small proportion attain functional cure, which is defined as HBV surface antigen-to-antibody seroconversion. Hepatitis B surface antigen (HBsAg) is a marker of persistent hepatitis B infection.
It has been observed that patients who had both hepatitis B and hepatitis C, and who were treated for their hepatitis C with 12 weeks of ledipasvir/sofosbuvir for had a decline in HBsAg levels. This study hypothesizes that a similar decrease would be seen in mono-infected hepatitis B subjects over the course of 12 weeks treatment with ledipasvir/sofosbuvir.
