Intellia Therapeutics to Present New Preclinical Data Highlighting In Vivo and Ex Vivo Genome Editing Advances at 2021 European Society of Gene & Cell Therapy Annual Congress

Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading clinical-stage genome editing company focused on developing curative therapeutics using CRISPR/Cas9 technology both in vivo and ex vivo, today announced the presentation of new data at the 29th Annual Congress of the European Society of Gene & Cell Therapy (ESGCT) meeting, taking place virtually from October 19-21, 2021.

“We are excited to share for the first time important preclinical data and new developments highlighting both our allogeneic T cell therapy platform as well as the utilization of lipid nanoparticle-based delivery of the CRISPR/Cas9 gene editing components to more efficiently engineer T cells for therapeutic use,” said Intellia Chief Scientific Officer Laura Sepp-Lorenzino, Ph.D. “Additionally, we will be presenting non-human primate data from our in vivo platform where we have demonstrated our ability to both insert a functional gene and inactivate a gene to treat AATD. For AATD, a genetic disease that can cause lung dysfunction and/or liver disease and which currently has no cure, our modular delivery platform provides us the optionality for patient-tailored treatments relevant to the disease manifestation. We look forward to sharing these data with the scientific community as we continue to advance our mission of delivering breakthrough genome editing treatments for people with severe diseases.”

About Intellia Therapeutics 

Intellia Therapeutics, a leading clinical-stage genome editing company, is developing novel, potentially curative therapeutics using CRISPR/Cas9 technology. To fully realize the transformative potential of CRISPR/Cas9, Intellia is pursuing two primary approaches. The company’s in vivo programs use intravenously administered CRISPR as the therapy, in which proprietary delivery technology enables highly precise editing of disease-causing genes directly within specific target tissues. Intellia’s ex vivo programs use CRISPR to create the therapy by using engineered human cells to treat cancer and autoimmune diseases. Intellia’s deep scientific, technical and clinical development experience, along with its robust intellectual property portfolio, have enabled the company to take a leadership role in harnessing the full potential of CRISPR/Cas9 to create new classes of genetic medicine.
