Precision BioSciences, Inc. is an advanced gene editing company dedicated to improving life (DTIL) with its proprietary ARCUS genome editing platform. Using ARCUS, the Company's pipeline consists of in vivo gene editing candidates designed to deliver cures for a range of genetic and infectious diseases. The ARCUS platform develops in vivo gene editing therapies for gene edits, including gene elimination, insertion, and excision. ARCUS particularly generates defined outcomes due to predominant repair using homology directed repair (HDR) as opposed to non-homologous end joining (NHEJ). The Company’s in vivo gene editing programs include PBGENE-HBV, PBGENE-PMM, PBGENE-NVS, PBGENE-DMD, PBGENE-LL2, PBGENE-LL3 and iECURE-OTC. PBGENE-HBV program is designed for the potential treatment of chronic hepatitis B virus (HBV). The Company is pursuing development of PBGENE-PMM as a potential opportunity for treatment of m.3243 associated primary mitochondrial myopathy (PMM).
