DURHAM, N.C., October 24, 2024--(BUSINESS WIRE)--Precision BioSciences, Inc. (Nasdaq: DTIL), a clinical stage gene editing company utilizing its novel proprietary ARCUS? platform to develop in vivo gene editing therapies for sophisticated gene edits, today announced that it has received Clinical Trial Application (CTA) approval in Moldova for its lead candidate, PBGENE-HBV. PBGENE-HBV is Precision’s wholly owned in vivo gene editing program designed to cure chronic hepatitis B by eliminating cccDNA, the key source of replicating hepatitis B virus (HBV), while also inactivating integrated HBV DNA in hepatocytes. The company has opened the Phase 1 clinical program and is moving towards dosing patients.

"At Precision, we remain laser-focused on execution, and our first CTA approval for PBGENE-HBV represents another significant milestone as we complete our transition to a clinical stage in vivo gene editing company. With rapid regulatory approval in hand, we are working diligently to screen and dose patients at our first clinical site in Moldova," said Michael Amoroso, Chief Executive Officer of Precision BioSciences. "In parallel, we are leveraging our robust regulatory package, which highlights the safety and potent antiviral effects of PBGENE-HBV in a variety of models, including non-human primates, to pursue additional CTA and IND approvals globally. This multi-track approach will enable us to accelerate enrollment into the trial and generate important clinical safety and efficacy data with the aim of bringing a potentially curative treatment to the nearly 300 million patients living with chronic hepatitis B globally."

Prior to PBGENE-HBV, no other modality has been investigated in a clinical trial setting that is designed to eliminate the root cause of disease, the cccDNA. Additionally, the current standard of care requires daily chronic treatment with nucleos(t)ide analogs and only offers patients a 1-3% chance of functional cure. Through its precision cutting, compact design, and simple structure, PBGENE-HBV is engineered to target the HBV viral genome and drive functional cures for patients with chronic hepatitis B. PBGENE-HBV leverages the ARCUS? gene editing platform by delivering an ARCUS nuclease-encoding mRNA to the liver via lipid nanoparticles. When expressed in HBV-infected hepatocytes, the ARCUS nuclease specifically cuts a highly conserved sequence in the hepatitis B viral genome and is designed to eliminate cccDNA and inactivate integrated HBV genomes. The ARCUS platform is derived from a naturally occurring enzyme and has been optimized for over 20 years into a ground-breaking and highly precise gene editing tool.
