- Oral Presentation to Highlight Efficacy and Specificity of ARCUS Nucleases for Potential Treatment of Chronic Hepatitis B
DURHAM, N.C.--(BUSINESS WIRE)--Apr. 20, 2023--
Precision BioSciences, Inc. (Nasdaq: DTIL), a clinical stage gene editing company developing ARCUS®-based ex vivo allogeneic CAR T and in vivo gene editing therapies, today announced an upcoming scientific presentation of preclinical data from its PBGENE-HBV program. PBGENE-HBV is designed to potentially eliminate hepatitis B virus (HBV) by targeting viral covalently closed circular DNA (cccDNA) in vivo. An abstract relating to the PBGENE-HBV program was selected for an oral presentation at the Global Hepatitis Summit 2023, being held April 25-28, 2023 in Paris, France.
“Specificity is paramount for a safe gene editing approach to eliminate hepatitis B virus,” said Jeff Smith, Chief Research Officer of Precision BioSciences. “Preclinical data suggests that a lack of nuclease specificity can lead to unfavorable off-target results including increased integrations of HBV genomes into the human genome, as well as translocations between integrations. However, ARCUS nucleases have been optimized to exhibit high levels of on-target editing and substantial reductions of both intracellular cccDNA and hepatitis B surface antigen (HBsAg) with no detectable translocations in primary human hepatocytes. These data continue to support our development of PBGENE-HBV as a potential curative approach for chronic HBV infection.”
Title: A gene editing approach for chronic hepatitis B: Elimination of hepatitis B virus in vivo by targeting cccDNA and integrated viral genomes with a sequence-specific ARCUS nuclease.
Date and Time: Wednesday, April 26, 8:30-10:30 (Paris time)
Session Title: HBV/HDV treatment targets

ARCUS is a proprietary genome editing technology discovered and developed by scientists at Precision BioSciences. It uses sequence-specific DNA-cutting enzymes, or nucleases, that are designed to either insert (knock-in), excise (knock-out), or repair DNA of living cells and organisms. ARCUS is based on a naturally occurring genome editing enzyme, I-CreI, that evolved in the algae Chlamydomonas reinhardtii to make highly specific cuts in cellular DNA and stimulate gene insertion at the cut site by homologous recombination. Precision's platform and products are protected by a comprehensive portfolio including nearly 100 patents to date.
