Intellia Therapeutics, Inc. announced that the U.S. Food and Drug Administration (FDA) has cleared the company?s Investigational New Drug (IND) application for NTLA-2001 for the treatment of transthyretin (ATTR) amyloidosis with cardiomyopathy. The global Phase 3 study of NTLA-2001, an in vivo CRISPR-based gene editing candidate, is expected to initiate by year-end 2023. 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 investigational 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 to the liver a two-part genome editing system: guide RNA specific to the disease-causing gene and messenger RNA that encodes the Cas9 enzyme, which carries out the precision editing. Robust preclinical and clinical data, showing deep and long-lasting transthyretin (TTR) reduction following in vivo inactivation of the target gene, supports NTLA-2001?s potential as a single-administration therapeutic.

Intellia leads development and commercialization of NTLA-2001 as part of a multi-target discovery, development and commercialization collaboration with Regeneron. The global Phase 1 trial is an open-label, multi-center, two-part study of NTLA-2001 in adults with hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN) or transthyretin amyloidosis with cardiomyopathy (ATTR-CM). The trial is now closed for enrollment.
