Leading epigenome editing company Tune Therapeutics presented data in support of its chronic Hepatitis B Virus (HBV) program, demonstrating the ability to durably silence essential mechanisms of viral replication and persistence across a range of model systems.

Key Points: 
  • Leading epigenome editing company Tune Therapeutics presented data in support of its chronic Hepatitis B Virus (HBV) program, demonstrating the ability to durably silence essential mechanisms of viral replication and persistence across a range of model systems.
  • Importantly, the TEMPO platform does this via epigenetic processes, and without cutting, damaging, or altering genomic DNA sequences in any way.
  • “Through the richness of these data sets, we found multiple repression candidates that worked well in both contexts.
  • As such, they represent the gold standard for assessing the dose and efficacy for liver-directed therapeutics ahead of human clinical trials.

Hepatitis B virus (HBV) causes inflammation and damage to the liver, leading to chronic infection and increased risk of death from liver cancer or cirrhosis.

Key Points: 
  • Hepatitis B virus (HBV) causes inflammation and damage to the liver, leading to chronic infection and increased risk of death from liver cancer or cirrhosis.
  • There is no cure for chronic hepatitis B and current treatments rarely result in functional cure, primarily due to persistence of viral DNA in the liver.
  • This integrated HBV DNA produces the viral protein, hepatitis B surface antigen (HBsAg), which is secreted in the blood.
  • Eliminating both the cccDNA and HBsAg are key parameters for achieving a functional cure of HBV,” said Jeff Smith, Co-Founder and Chief Research Officer at Precision Biosciences.
