Today\u2019s in vivo<\/i> gene editing R&D event showcases the power of our ARCUS genome editing platform \u2013 including key demonstrations of capabilities, such as gene insertion and mitochondrial DNA gene editing \u2013 which offers distinct advantages in this emerging field,\u201d commented Matt Kane, CEO and co-founder of Precision BioSciences. \u201cWe are excited to announce a new collaboration with iECURE which we expect to help us expedite clinical validation of the ARCUS platform for both gene knockout and gene insertion.\u201d\n<\/p>\n \n\u201cToday, we are excited to share additional data highlighting the precision and versatility of our ARCUS platform, which is designed to enable safe, specific and efficient gene editing. Since ARCUS can be delivered via AAV or LNP, it has potential utility in treating diseases in the liver as well as many genetic diseases that affect tissues beyond the liver. In addition, the unique enzymology of ARCUS enables it to make complex gene insertion and gene repair edits more efficiently than other editing platforms,\u201d said Derek Jantz, Ph.D., Chief Scientific Officer and co-founder of Precision. \u201cWe believe these unique attributes of ARCUS support its differentiation for in vivo<\/i> use and its potential to treat a broader range of genetic diseases than other editing technologies. We are very excited about our near-term pipeline and expect ARCUS to deliver on its full promise as we take on more challenging programs.\u201d\n<\/p>\n \nPrecision expects that three of its preclinical programs will advance to investigational new drug (IND)\/clinical trial application (CTA) in the next three years:\n<\/p>\n \nAnnounced today in a separate release, Precision BioSciences has signed a license and collaboration agreement with iECURE, a mutation-agnostic in vivo<\/i> gene editing company striving to cure devastating diseases with high unmet need, co-founded by James M. Wilson, M.D., Ph.D. Using Precision\u2019s PCSK9-directed ARCUS nuclease, iECURE plans to advance Precision\u2019s PBGENE-PCSK9 candidate into a Phase 1 study in FH and gain access to Precision\u2019s PCSK9-directed ARCUS nuclease to develop four other pre-specified gene insertion therapies for genetic diseases, focusing initially on liver diseases. Precision will retain rights to PBGENE-PCSK9, including for FH and all products developed for genetic indications except those licensed to iECURE. In return for its license grant, Precision will receive an equity stake in iECURE and is eligible to receive milestone and royalty payments on sales of iECURE products developed with ARCUS.\n<\/p>\n \nPresentations from Precision\u2019s in vivo<\/i> Gene Editing R&D event will highlight the Company\u2019s clinical development strategy and updates on the following wholly-owned and partnered preclinical programs using ARCUS-mediated editing:\n<\/p>\n Featured Preclinical Data<\/b><\/p>\n \n\u201cResearch conducted by the Gene Therapy Program has shown ARCUS is capable of precise edits that can be applied broadly across genetic diseases in a mutation-dependent manner,\u201d said Dr. James M. Wilson. \u201cAdditionally, as reported today, ARCUS has demonstrated highly efficient gene insertion with a PCSK9-directed nuclease that will be foundational to iECURE in addressing rare genetic diseases, as well as long-term durability reflecting its curative potential with a single administration. Taken together, these findings continue to support what we have learned over years of collaborating with Precision: that the unique properties of ARCUS are differentiated versus other tools in this field.\u201d\n<\/p>\n \nNew preclinical data to be presented today, and data previously presented at the American Society of Gene & Cell Therapy Annual Meeting, show that ARCUS efficiently targeted and degraded HBV cccDNA in HBV-infected primary human hepatocytes and reduced expression of HBV S-antigen (HBsAg) by as much as 95%. Similar levels of HBsAg reduction were observed in a newly developed mouse model of HBV infection following administration of ARCUS mRNA using lipid nanoparticle (LNP) delivery. Precision will pursue clinical development of its PBGENE-HBV candidate using LNP delivery and expects to submit an IND in 2024.\n<\/p>\n \nRecent preclinical studies used mitochondrial-targeted ARCUS (mitoARCUS) to selectively eliminate mutant mitochondrial genomes that cause disease in cell and animal models. In work conducted by Precision BioSciences, a hybrid cell model with a mixture of wild-type (healthy) and mutant mitochondrial genomes, a single treatment with mitoARCUS mRNA converted the cells to >99% wild-type. Work led by Carlos T. Moraes, Ph.D., Esther Lichtenstein Professor in Neurology at the University of Miami Miller School of Medicine and in a mouse model of mitochondrial disease and published online in Nature Communications<\/i><\/a> on May 28, 2021, found that mitoARCUS delivered by AAV effectively targeted and depleted mutant mitochondrial genomes in multiple tissues. No editing of potential nuclear off-target sites could be detected, and liver and skeletal muscle showed robust elimination of mutant mtDNA with concomitant restoration of markers of mitochondrial function.\n<\/p>\n \nData will be presented on the clinical nuclease which is expected to be delivered by AAVrh79 in a Phase 1 clinical study to be conducted by iECURE.\n<\/p>\n \nNHP data supporting this approach has shown, on average, a 98.0% reduction in HAO1 mRNA and a 97.9% reduction in the encoded protein after a single administration of an AAV vector encoding ARCUS. Compared to published results with siRNAs targeting HAO1, Precision\u2019s approach appeared to provide an improved metabolic profile with the potential for long-term benefit from a single dose. Precision has initiated IND-enabling activities and expects to submit an IND application for this program in 2023 using LNP delivery.\n<\/p>\n \nIn November 2020, Precision and Lilly announced an exclusive license agreement to utilize ARCUS genome editing for the research and development of up to six potential in vivo<\/i> targets for genetic disorders. The collaboration initially included three gene targets, with the lead program targeting the dystrophin gene responsible for DMD (PBGENE-DMD<\/b>). In addition, Precision will use ARCUS for one liver-directed target (PBGENE-LLY2<\/b>) and one CNS-directed target (PBGENE-LLY3<\/b>).\n<\/p>\n \nDr. Jantz continued, \u201cThe versatility of our platform offers us the optionality to pursue numerous therapeutic applications through strategic partnerships, enabling us to capture more of the value of the ARCUS technology and accelerate key programs. For example, in addition to rapidly advancing PBGENE-PCSK9 to the clinic, iECURE will provide critical validation of ARCUS\u2019 gene-insertion capabilities. Lilly will help us research ARCUS-mediated editing in muscle and CNS. Even as we aggressively invest in wholly-owned programs, we will continue to leverage collaborations that enable us to explore novel applications of ARCUS and reach patients quicker.\u201d\n<\/p>\n \nThe Company\u2019s balance of cash and cash equivalents is approximately $167 million as of August 31, 2021. The Company continues to expect that existing cash and cash equivalents will be sufficient to fund planned operations into 2023.\n<\/p>\n Call and Webcast Information<\/b><\/p>\n \nPrecision’s gene editing R&D event is being held today, September 9, 2021, at 8:00 a.m. ET.
