Current trends and advances in antiviral therapy for chronic hepatitis B
Chronic hepatitis B virus(HBV)infection is a global public health concern.Existing antiviral drugs,including nucleos(t)ide analogs and interferon-α,can suppress HBV replication and improve the prognosis.However,the persistence of covalently closed circular DNA(cccDNA),the integration of HBV-DNA into the host genome,and compromised immune responses impede the successful treatment of hepatitis B.While achieving a functional cure of HBV remains elusive with the current treatment methods,this is the goal of new therapeutic approaches.Therefore,developing novel antiviral drugs is necessary for achieving a functional or complete cure for chronic hepatitis B.In recent years,substantial progress has been made in drug discovery and development for HBV infection.Direct-acting antiviral agents such as entry inhibitors,capsid assembly modulators,subviral particle release inhibitors,cccDNA silencers,and RNA interference molecules have entered clinical trials.In addition,several immunomodulatory agents,including toll-like receptor agonists,therapeutic vaccines,checkpoint inhibitors,and monoclonal antibodies,are also making their way toward clinical use.In this review,we summarize the recent progress and limitations of chronic hepatitis B treatment and discuss perspectives on approaches to achieving functional cure.Although it will take some time for these new antiviral drugs to be widely used in clinical practice,combination therapy may become a preferable treatment option in the future.
