Intellia Therapeutics to Present the First-Ever Clinical Data From Patients Redosed with an Investigational In Vivo CRISPR Gene Editing Therapy at the Peripheral Nerve Society Annual Meeting 2024

CAMBRIDGE, Mass., June 17, 2024 (GLOBE NEWSWIRE) -- Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading clinical-stage gene editing company focused on revolutionizing medicine with CRISPR-based therapies, today announced the acceptance of an abstract featuring redosing data from the Phase 1 study of NTLA-2001 has been selected for an oral presentation at the Peripheral Nerve Society Annual Meeting, taking place June 22 – 25 in Montreal, Canada. NTLA-2001 is an investigational in vivo CRISPR-based gene editing therapy designed to be a single-dose treatment for transthyretin (ATTR) amyloidosis.

In the dose-escalation portion of the Phase 1 study, the initial three patients received the lowest dose of 0.1 mg/kg and subsequently received a follow-on dose of 55 mg. These data will be the first-ever clinical data from patients redosed with an in vivo CRISPR-based gene editing candidate and provide insight on the safety and pharmacodynamic effect. While repeat dosing is not planned for the NTLA-2001 program for ATTR amyloidosis, a redosing option could be an important advantage of Intellia’s non-viral, lipid nanoparticle (LNP)-based delivery platform for future investigational therapies where a target additive effect is desired.

About NTLA-2001
Based on Nobel Prize-winning CRISPR/Cas9 technology, NTLA-2001 has the potential to become the first one-time treatment for transthyretin (ATTR) amyloidosis. NTLA-2001 is designed to inactivate the TTR gene that encodes for the transthyretin (TTR) protein. NTLA-2001 is the first investigational CRISPR therapy to be administered systemically to edit genes inside the human body. Interim Phase 1 clinical data showed the administration of NTLA-2001 led to consistent, deep and long-lasting TTR reduction. Intellia leads development and commercialization of NTLA-2001 as part of a multi-target discovery, development and commercialization collaboration with Regeneron.

About Transthyretin (ATTR) Amyloidosis
Transthyretin amyloidosis, or ATTR amyloidosis, is a rare, progressive and fatal disease. Hereditary ATTR (ATTRv) amyloidosis occurs when a person is born with mutations in the TTR gene, which causes the liver to produce structurally abnormal transthyretin (TTR) protein with a propensity to misfold. These damaged proteins build up as amyloid in the body, causing serious complications in multiple tissues, including the heart, nerves and digestive system. ATTRv amyloidosis predominantly manifests as polyneuropathy (ATTRv-PN), which can lead to nerve damage, or cardiomyopathy (ATTRv-CM), which can lead to heart failure. Some individuals without the genetic mutation produce non-mutated, or wild-type TTR proteins that become unstable over time, misfolding and aggregating in disease-causing amyloid deposits. This condition, called wild-type ATTR (ATTRwt) amyloidosis, primarily affects the heart. There are an estimated 50,000 people worldwide living with ATTRv amyloidosis and between 200,000 and 500,000 people with ATTRwt amyloidosis. There is no known cure for ATTR amyloidosis and currently available medications are limited to slowing accumulation of misfolded TTR protein.
