Precision BioSciences (Nasdaq: DTIL) presented preclinical data at the ESGCT 31st Annual Congress showcasing their ARCUS platform'scapability for high-efficiency gene editing through homology-directed repair (HDR). The research demonstrated gene insertion rates exceeding 85% in T cells and 39% in non-dividing primary human hepatocytes.
The ARCUS platform showed versatility in DNA editing, achieving all twelve possible base changes, specific base removal and insertions, and whole gene replacements. This capability extends beyond current limitations of base editors and prime editors, potentially offering broader therapeutic applications for diseases requiring function restoration.
