CAMBRIDGE, Mass., Oct. 31, 2018 (GLOBE NEWSWIRE) – Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading genome editing company focused on developing curative therapeutics using CRISPR/Cas9 technology bothin vivo andex vivo, announced financial results and operational developments for the third quarter of 2018.

“We made excellent progress across ourin vivo andex vivo programs in the third quarter. In our ATTR program, Intellia previously reported that our proprietary LNP delivery technology could edit genes in the liver ofnon-human primates sufficiently to reduce TTR protein levels to a potential therapeutic range. Our continuedin vivo delivery enhancement efforts have now produced striking improvements over these liver editing and protein knockdown levels. Data from the initial application of these enhancements in our ATTR program suggest that we may be able to double our previously reported liver editing results and more significantly reduce circulating protein beyond recognized therapeutic levels, at a lower, well-tolerated dose. We are applying these enhancements to develop a superior ATTR development candidate and we believe we can leverage these enhancements to significantly improve the performance of our development candidates forfollow-onin vivo programs,” said Intellia President and Chief Executive Officer John Leonard, M.D.

“Furthermore, in our insertion programs, we successfully introduced functioning genes in mice using our modular LNP delivery system of CRISPR/Cas9 in combination with our proprietary AAV insertion templates developed in collaboration with Regeneron. In our presentation at ESGCT, Intellia was the first company to demonstrate technology that can insert genesin mice to produce, and fine tune, protein levels up to and greater than those required for normal human physiology.

“In parallel to thesein vivo achievements, we are rapidly advancing ourex vivo immuno-oncology efforts, beginning with the development ofbest-in-class CRISPR-edited T cells for WT1,” added Dr. Leonard.

Third Quarter 2018 Operational Highlights and Recent Corporate Developments Include:

Transthyretin Amyloidosis Program Enhancements

Intellia announced today results from its transthyretin amyloidosis (ATTR)non-human primate (NHP) studies, conducted in collaboration with Regeneron Pharmaceuticals, Inc., related to its enhancements of the cargo components of its lipid nanoparticle (LNP)-based delivery system. These novel component enhancements, which are part of the ongoing development of its proprietary and modularin vivo delivery platform, have produced unprecedented results, achieving up to 78 percent (mean of 59 percent) liver editing in our most recent NHP study. The corresponding transthyretin (TTR) protein reduction at 21 days showed a decrease from baseline of up to 96 percent (mean reduction of 78 percent) after a single dose. This substantially improved level of liver editing, achieved with a lower dose and well-tolerated safety profile, compares with mean editing levels of 34 percent in Intellia’s previously reported NHP studies.

Based on these new data, the Company is pursuing confirmatory studies with the goal of integrating enhanced cargo components in its Investigational New Drug (IND)-enabling studies and submission of an IND (previously planned for the end of 2019, but now targeted for 2020) for ATTR. In addition, the Company intends to apply these technology improvements to the rest of itsin vivoproduct pipeline.

“We are elated to have achieved such impressive and compelling editing and protein knockdown results in our NHP studies. We believe that this approach, while introducing a relatively short delay to our previous IND timeline, will ultimately yield the best possible treatment option for patients – one that we hope will clearly advance the standard of care well beyond approved and potential therapies for the treatment of ATTR,” added Dr. Leonard.

Advancing Complex Genome Editing Capabilities

Intellia advanced its complex genome editing capabilities with the first robust demonstration of CRISPR-mediated, targeted insertion of transgenes in the liver of mice. The Company used its modular LNP delivery system of CRISPR/Cas9 in combination with Intellia’s proprietary modular adeno-associated virus (AAV) to insert donor template DNA into the albumin locus of mice. In collaboration with Regeneron, the Company usedF9 as a model gene, which encodes Factor IX (FIX) protein, which is the clotting factor deficient in patients with hemophilia B. Using a proprietarybi-directional template platform technology, researchers showed that they can detect hybridmAlb-hF9transcripts in over 50 percent of hepatocytes following a single dose and measured circulating human FIX protein levels of more than 30,000 ng/mL. These levels are higher than those required in a clinical setting and correspond to levels predicted to be up to 40 to 300 times higher than those capable of preventing spontaneous bleeding episodes in hemophilia B patients, relative to wildtype or a hyperfunctional version ofF9,respectively (sources: George, et al, NEJM, 2017; Simioni et al, NEJM, 2009). Furthermore, the Company observed that varying either the LNP or AAV dose modulated FIX levels. Protein levels remained stable after dosing throughout the12-week observation period.

Intellia also applied the hybridLNP-AAV delivery approach to its wholly ownedin vivo preclinical program inalpha-1 antitrypsin deficiency (AATD).Alpha-1 antitrypsin (AAT), a protein that protects the lungs and is mutated or absent in patients with AATD, is produced by theSERPINA1gene. To produce AAT protein, Intellia combined CRISPR/Cas9 delivery by LNP with theSERPINA1DNA template delivered by AAV into the albumin locus. The targeted insertion generated gene expression levels in mice that correspond to levels that protect against the loss of pulmonary capacity in humans. This milestone underscores the utility of Intellia’s modularLNP-based delivery system and shows significant progress in developing anin vivogenome editing solution for AATD.

Progressing Transgenic T Cell Receptor Technology

Intellia and its research collaborator, Ospedale San Raffaele (OSR), presented data at the 26^th Annual Congress of the European Society of Gene and Cell Therapy (ESGCT) showing progression in the Company’s leadex vivo program for the treatment of acute myeloid leukemia (AML), utilizing transgenic T cell receptor (TCR) technology.In vitro data demonstrated that CRISPR/Cas9 editing resulted in over 90 percent knockout of endogenous TCRs and insertion of Wilms’ Tumor 1 (WT1) epitope-specific TCRs. The resulting engineered T cells were fully functional and killed a significant percentage of leukemic blasts. The Company continues to advance its firstex vivo development candidate, which is undergoingin vitro andin vivo functional testing.

Expanded Board of Directors and Management Team

Intellia announced today the appointment of Jesse Goodman, M.D., to its board of directors. Dr. Goodman brings more than three decades of expertise in medical research and public health as a professor, practicing clinician and former director of the U.S. Food and Drug Administration’s (FDA) Center for Biologics Evaluation and Research (CBER).

“We are thrilled to have someone with the broad scientific, public health, regulatory and clinical credentials of Jesse join Intellia’s board of directors,” said Intellia Chairman Perry Karsen. “During his time at the FDA, Jesse demonstrated exceptional leadership in ensuring that the agency and companies could work together to advance scientific innovation and responsibly enhance patient access to safe and effective therapies. We expect his contributions will be invaluable as Intellia begins transitioning to a biotech company approaching clinical trials with patients.”

Dr. Goodman is currently a professor of medicine at Georgetown University, where he directs the Center on Medical Product Access, Safety and Stewardship (COMPASS). As an attending physician in infectious diseases, he also is an active clinician and educator. Additionally, he serves as an independentnon-executive director for GlaxoSmithKline plc.; as president and trustee of the U.S. Pharmacopeial Convention; and on the Regulatory Working Group of the Coalition on Epidemic Preparedness Innovation (CEPI). Dr. Goodman was chief scientist at the FDA from 2009 through 2014, during which time he led preparations for and responses to major public health threats, including emerging infectious diseases, disasters and terrorism. He previously also served as the FDA’s deputy commissioner for science and public health and as director of CBER. Dr. Goodman has a bachelor of arts in biology from Harvard University; earned a master’s in public health from the University of Minnesota; and received his doctor of medicine from the Albert Einstein College of Medicine. He completed his residency and fellowship training at the Hospital of the University of Pennsylvania and at the University of California at Los Angeles. Dr. Goodman is board-certified in internal medicine, infectious diseases and oncology, and has been elected to the American Society for Clinical Investigation and to the U.S. National Academy of Medicine.
