Chronic Hepatitis B
Conditions
Brief summary
This is a randomized, double-blinded, placebo-controlled, phase IIa study to evaluate safety and efficacy of TQ-A3334 combined with entecavir in the untreated or HBV DNA negative subjects with Chronic Hepatitis B.
Interventions
TQ-A3334 is a kind of TLR7 receptor agonist.
Placebo is a treatment which is designed to have no therapeutic value.
Entecavir (ETV) tablet is an antiviral medication used in the treatment of hepatitis B virus (HBV) infection.
