Intellia Therapeutics Announces Presentations at the 2019 Annual Congress of the European Society of Gene and Cell Therapy (ESGCT)
Intellia’s data includes important updates about the company’s programs and platform development activities:
“In Vivo Gene Knockout Followed by Targeted Gene Insertion Results in Simultaneous Reduced Mutant Protein Levels and Durable Transgene Expression”
Intellia will present data on its alpha-1 antitrypsin deficiency (AATD) program, which uses a modular hybrid delivery system combining lipid nanoparticle (LNP) encapsulated CRISPR/Cas9 with an adeno-associated virus (AAV) donor DNA template. Intellia’s gene knockout approach eliminates the production of the faulty PiZ variant of the protein, while targeted insertion of a wild-type gene copy facilitates production of a functional circulating protein. This builds on Intellia’s similar approach for targeted gene insertion of Factor 9, which achieved increased levels of circulating human Factor IX protein through two months in non-human primates and sustained through 12 months in mice.
Abstract number: OR48
Session 5b: New delivery systems and technologies
“In Silico, Biochemical and Cell-Based Integrative Genomics Identifies Precise CRISPR/Cas9 Targets for Human Therapeutics”
This poster presentation will highlight Intellia’s approach to assess off-target activity to identify highly specific CRISPR/Cas9 guides. Researchers demonstrated that potential off-target editing profiles discovered through empirical data from biochemical approaches were the most sensitive and accurate.
Presenter: Daniel O’Connell, Ph.D.
Poster ID Number: P655
“Generation of a Library of WT1-Specific T Cell Receptors (TCR) for TCR Gene Edited T Cell Therapy of Acute Leukemia”
This poster presentation focuses on Intellia’s ongoing research collaboration with IRCCS Ospedale San Raffaele to develop CRISPR/Cas9-edited T cell therapies to address intractable cancers, such as acute myeloid leukemia (AML). Researchers have successfully established a protocol enabling consistent and efficient tumor-specific TCR isolation and characterization from healthy donors. Based on these results, Intellia has selected multiple lead TCRs, which are undergoing development candidate evaluation.
Poster ID Number: P111
“Engineering of Highly Functional and Specific Transgenic T Cell Receptor (TCR) T Cells Using CRISPR-Mediated In-Locus Insertion Combined with Endogenous TCR Knockout”
This poster presentation focuses on the company’s T cell engineering technology, which is being applied in its Wilms’ Tumor 1 (WT1) lead ex vivo program. Intellia has identified an efficient CRISPR/Cas9-mediated process that inserts tumor-specific TCRs with high yield into the
Poster ID Number: P162
“CRISPR/Cas9-Mediated Gene Knockout to Address Primary Hyperoxaluria”
This poster presentation will demonstrate the effects of independent CRISPR/Cas9-mediated knockout of each of two target genes involved in oxalate formation, lactate dehydrogenase A (LDHA) and hydroxyacid oxidase 1 (HAO1), to address primary hyperoxaluria type 1 (PH1).
Poster ID Number: P552
Intellia Therapeutics is a leading genome editing company focused on developing curative therapeutics using the CRISPR/Cas9 system. Intellia believes the CRISPR/Cas9 technology has the potential to transform medicine by permanently editing disease-associated genes in the human body with a single treatment course, and through improved cell therapies that can treat cancer and immunological diseases, or can replace patients’ diseased cells. The combination of deep scientific, technical and clinical development experience, along with its leading intellectual property portfolio, puts Intellia in a unique position to unlock broad therapeutic applications of the CRISPR/Cas9 technology and create a new class of therapeutic products.
