DURHAM, N.C.--(BUSINESS WIRE)--May 1, 2025-- Precision BioSciences, Inc. (Nasdaq: DTIL), a clinical stage gene editing company utilizing its novel proprietary ARCUS® platform to develop in vivo gene editing therapies, including gene elimination, gene insertion, and gene excision programs, today announced that five abstracts detailing Precision’s wholly owned or partnered programs have been accepted for presentation at the American Society of Gene and Cell Therapy (ASGCT) Annual Meeting being held May 13-17, 2025, in New Orleans, Louisiana.

"We are pleased to present new data at ASGCT from multiple programs across our in vivo gene editing pipeline, highlighting the potentially unmatched breadth and therapeutic potential of our ARCUS gene editing technology,” said Michael Amoroso, President and Chief Executive Officer at Precision BioSciences. “Clinically, we have made progress advancing our lead program, PBGENE-HBV, which is a novel gene editing approach being evaluated in a first-in-human study for chronic hepatitis B, and we look forward to sharing initial safety data from the first two dose cohorts at ASGCT. Additionally, we continue to be excited by the promising clinical results generated thus far by our partner iECURE for ECUR-506 in OTC deficiency, which utilizes an ARCUS nuclease and will also be presenting data at this conference."

“We are also excited to share promising preclinical results from two muscle programs, PBGENE-3243 program for m.3243-associated mitochondrial disease and PBGENE-DMD for the treatment of Duchenne Muscular Dystrophy (DMD),” Mr. Amoroso continued. “Collectively, these presentations highlight the progress we are making with ARCUS by deploying a variety of gene edit types, including gene elimination, gene insertion and gene excision across a range of complex genetic diseases as we seek to develop durable, curative treatments for patients."

About Precision BioSciences, Inc.

Precision BioSciences, Inc. is a clinical stage gene editing company dedicated to improving life (DTIL) with its novel and proprietary ARCUS® genome editing platform that differs from other technologies in the way it cuts, its smaller size, and its simpler structure. Key capabilities and differentiating characteristics may enable ARCUS nucleases to drive more intended, defined therapeutic outcomes. Using ARCUS, the Company’s pipeline is comprised of in vivo gene editing candidates designed to deliver lasting cures for the broadest range of genetic and infectious diseases where no adequate treatments exist. For more information about Precision BioSciences, please visit www.precisionbiosciences.com.

The ARCUS® platform is being used to develop in vivo gene editing therapies for sophisticated gene edits, including gene insertion (inserting DNA into gene to cause expression/add function), elimination (removing a genome e.g. viral DNA or mutant mitochondrial DNA), and excision (removing a large portion of a defective gene by delivering two ARCUS nucleases in a single AAV such as in the DMD program).
