- Oral presentation to include additional data on patient durability treated with NTLA-2001, the first-ever systemically administered live Experimental CRISPR therapy
- Submission must include data supporting fixed-dose selection into the ongoing single-dose expansion cohort of the polyneuropathy arm
CAMBRIDGE, Mass., June 08, 2022 (GLOBE NEWSWIRE) — Intellia Therapeutics, Inc. (NTLA, Financial), a leading genome editing company focused on developing potentially curative therapies leveraging CRISPR-based technologies, today announced that interim clinical data from the Phase 1 study of NTLA-2001 , an investigational therapy in development for the treatment of transthyretin-mediated (ATTR) amyloidosis, will be shared in an oral presentation at the European Association for the Study of the Liver™ 2022 International Liver Congress, taking place from June 22-26 in London.
“We are pleased to present longer-term follow-up data from the first-in-man study of NTLA-2001, which is designed to potentially halt progression and reverse ATTR amyloidosis,” said John Leonard, President- CEO of Intellia. , MD “We look forward to sharing interim data that we believe demonstrates the potential of our experimental CRISPR-based therapy as a single-dose treatment that provides a profound and long-lasting response.”
The presentation will include new data from the ongoing Phase 1 study evaluating NTLA-2001 in people with hereditary ATTR amyloidosis with polyneuropathy (ATTRv-PN). These include additional results from the four dose-escalation cohorts in Part 1, highlighting the durability of response after a single dose of NTLA-2001. Data supporting fixed dose selection for Part 2, the single-dose expansion cohort of the polyneuropathy arm, will also be presented.
The presentation will build on interim data presented in February, which showed significant reductions in serum TTR levels from baseline in a dose-dependent manner in 15 patients with vATTR-PN. At the highest dose tested, 1.0 mg/kg, the mean and maximum reductions in serum TTR were 93% and 98%, respectively, on day 28 in the six treated patients. The company also previously announced that it is now evaluating a fixed dose of 80 mg in Part 2 of the Phase 1 study, which is expected to provide similar exposure to the 1.0 mg/kg dose in the vATTR target population. -PN, and that the first patient was dosed in the expansion cohort in the polyneuropathy arm. Intellia is also continuing to dose patients in the cardiomyopathy arm of the Phase 1 study, which is evaluating NTLA-2001 in dose-escalation cohorts of people with ATTR amyloidosis with cardiomyopathy (ATTR-CM).

About Transthyretin Amyloidosis (ATTR)
Transthyretin amyloidosis, or ATTR amyloidosis, is a rare, progressive and fatal disease. Hereditary ATTR amyloidosis (vATTR) occurs when a person is born with mutations in the TTR , which causes the liver to produce a structurally abnormal protein transthyretin (TTR) with a propensity to misfold. These damaged proteins build up as amyloid in the body, leading to serious complications in many tissues, including the heart, nerves and digestive system. VATTR amyloidosis primarily manifests as polyneuropathy (vATTR-PN), which can lead to nerve damage, or cardiomyopathy (vATTR-CM), which can lead to heart failure. Some people without genetic mutation produce unmutated or wild-type TTR proteins that become unstable over time, fold, and aggregate into pathogenic amyloid deposits. This condition, called wild-type ATTR amyloidosis (ATTRwt), primarily affects the heart. There are an estimated 50,000 people worldwide with ATTRv amyloidosis and between 200,000 and 500,000 people with ATTRwt amyloidosis.
Based on Nobel Prize-winning CRISPR/Cas9 technology, NTLA-2001 could potentially be the first single-dose treatment for ATTR amyloidosis. NTLA-2001 is the first experimental CRISPR therapy candidate to be administered systemically, or through a vein, to edit genes inside the human body. Intellia’s proprietary non-viral platform deploys lipid nanoparticles to deliver a two-part genome-editing system to the liver: guide RNA specific to the disease-causing gene and messenger RNA that encodes the Cas9 enzyme, which performs precision editing. Strong preclinical data, showing profound and long-lasting transthyretin (TTR) reduction after live inactivation of the target gene, supports the potential of NTLA-2001 as a single-dose therapeutic. Intellia is leading the development and commercialization of NTLA-2001 in a multi-target discovery, development and commercialization collaboration with Regeneron. The global Phase 1 trial is an open-label, multicenter, two-part study of NTLA-2001 in adults with hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN) or transthyretin amyloidosis with cardiomyopathy (ATTR-CM ).

About Intellia Therapeutics
Intellia Therapeutics, a leading clinical-stage genome editing company, is developing potentially curative new therapies by leveraging CRISPR-based technologies. To fully realize the transformative potential of CRISPR-based technologies, Intellia is pursuing two main approaches. From the company live The programs use intravenously administered CRISPR as therapy, in which proprietary delivery technology enables highly precise editing of pathogenic genes directly into specific target tissues. from Intellia ex-vivo the programs use CRISPR to create the therapy using human cells engineered to treat cancer and autoimmune diseases. Intellia’s deep scientific, technical and clinical experience, along with its strong intellectual property portfolio, has enabled the company to play a leadership role in harnessing the full potential of genome editing for create new classes of genetic medicine.
