Intellia Therapeutics' Investigational CRISPR Treatment NTLA-2001 Receives European Union Orphan Drug Designation for ATTR Amyloidosis

CAMBRIDGE, Mass., March 30, 2021 (GLOBE NEWSWIRE) -- Intellia Therapeutics, Inc. NTLA, a leading genome editing company focused on developing curative therapeutics using CRISPR/Cas9 technology both in vivo and ex vivo, announced today that the European Commission (EC) has granted orphan drug designation to NTLA-2001. This investigational medicinal product is being developed as a treatment for transthyretin amyloidosis (ATTR), a rare condition that can impact a number of organs and tissues within the body through the accumulation of misfolded transthyretin (TTR) protein deposits. NTLA-2001 is the first experimental CRISPR therapy – a Nobel Prize-winning technology – to be administered systemically via intravenous dosing to edit a gene, specifically the TTR gene, that encodes the production of TTR protein, inside the human body. In addition to being the first therapy of its kind, it also has the potential to be the first curative treatment and it may be able to halt and reverse ATTR progression.

"This news is a significant milestone for NTLA-2001 and the ATTR patient community," said Intellia President and Chief Executive Officer John Leonard, M.D. "We are pleased that the EC recognizes the potential significant benefit of NTLA-2001 in the treatment of patients with this debilitating disease where there is no cure. We look forward to advancing the global development of this genome editing product in collaboration with Regeneron."

This decision by the EC follows the initiation of Intellia's global Phase 1 study to evaluate NTLA-2001 for hereditary ATTR with polyneuropathy (hATTR-PN). The trial aims to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of NTLA-2001. Following safety assessment and dose optimization, Intellia intends to further evaluate NTLA-2001 in both polyneuropathy and cardiomyopathy patients. Orphan drug designation is granted to therapies that are intended for the treatment, prevention, or diagnosis of life threatening or chronically debilitating rare diseases where there are either no treatments or no satisfactory therapeutic options. The designation provides regulatory, financial and commercial incentives to develop therapies for rare diseases defined as having a prevalence of less than five in 10,000 people in the European Union.

About NTLA-2001
NTLA-2001 is the first experimental CRISPR therapy to be administered systemically, or through a vein, to edit a gene inside the human body. Intellia's proprietary non-viral platform utilizes lipid nanoparticles designed to deliver to the liver a simple, two-part genome editing system: guide RNA specific to the disease-causing gene and messenger RNA that encodes the Cas9 protein. Intellia's robust preclinical data showing deep and long-lasting transthyretin (TTR) reduction following knockout of the target gene in vivo support NTLA-2001's potential as a single dose of treatment. NTLA-2001 is part of a co-development/co-promotion agreement between Intellia, the lead development and commercialization party, and Regeneron Pharmaceuticals, Inc.

About Transthyretin Amyloidosis (ATTR)
Transthyretin amyloidosis, or ATTR, is a rare, progressive and fatal disease. Hereditary ATTR (hATTR) occurs when a person is born with a specific DNA mutation in the TTR gene, which causes the liver to produce a protein called transthyretin (TTR) in a misfolded form and build up in the body. hATTR can manifest as polyneuropathy (hATTR-PN), which can lead to nerve damage, or cardiomyopathy (hATTR-CM), which involves heart muscle disease that can lead to heart failure. In addition, non-mutated, or wild-type TTR protein, can also accumulate in the body, leading to wild-type ATTR (wtATTR). There are an estimated 50,000 hATTR patients worldwide and between 200,000 and 500,000 people with wtATTR.

About Intellia Therapeutics
Intellia Therapeutics is a leading genome editing company, focused on the development of proprietary, potentially curative therapeutics using the CRISPR/Cas9 system. Intellia believes the CRISPR/Cas9 technology has the potential to transform medicine by both producing therapeutics that permanently edit and/or correct disease-associated genes in the human body with a single treatment course, and creating enhanced engineered cells that can treat oncological and immunological diseases. Intellia's combination of deep scientific, technical and clinical development experience, along with its leading intellectual property portfolio, puts it in a unique position to unlock broad therapeutic applications of the CRISPR/Cas9 technology and create new classes of therapeutic products.
