Recent Advances in Hepatitis B Treatment.

Area of Science:

• Hepatology
• Virology
• Immunology

Background:

• Hepatitis B virus infection impacts over 250 million people globally, leading to significant mortality.
• Current treatments like pegylated interferon and nucleos(t)ide analogues have limitations and cannot fully eliminate the virus.
• Achieving a functional cure for Hepatitis B virus remains a significant clinical challenge.

Purpose of the Study:

• To review the Hepatitis B virus replication cycle.
• To examine existing approved anti-HBV drugs.
• To analyze emerging novel therapeutic strategies for HBV infection.

Main Methods:

• Literature review of Hepatitis B virus life cycle.
• Analysis of current antiviral therapies for HBV.
• Evaluation of novel therapeutic approaches in preclinical and clinical development.

Main Results:

• New therapeutic strategies target various stages of the HBV life cycle, including entry inhibition, cccDNA epigenetic control, immune modulation, RNA interference, ribonuclease H inhibition, and capsid assembly modulation.
• Promising preclinical data exists for these novel agents.
• Several leading novel molecules are currently undergoing clinical evaluation.

Conclusions:

• Despite available vaccines, Hepatitis B virus remains a persistent global health threat.
• Novel therapeutic approaches targeting the HBV life cycle offer new hope for achieving a functional cure.
• Continued research and clinical evaluation are crucial for advancing Hepatitis B virus treatment.
