AI Technical Summary

Technical Problem

Existing treatments for hepatitis B and hepatitis D are not very effective and cannot effectively suppress hepatitis B virus antigens HBsAg and/or HBeAg, leading to chronic infection that is difficult to control. Existing drugs have side effects and cannot achieve functional cure.

Method used

Modified or unmodified oligonucleotides with a length of 24-40 nt, having specific core sequences and nucleoside internucleotide modifications such as thiophosphate bonds, can complement the hepatitis B virus genome, target viral RNA, and inhibit the expression of viral gene products.

Benefits of technology

It significantly inhibits hepatitis B virus DNA replication and reduces serum HBsAg and HBeAg concentrations, showing the potential for functional cure of hepatitis B and is suitable for use in combination with existing therapies.
