Intellia Therapeutics Announces First Patient Dosed in the Phase 3 MAGNITUDE Study of NTLA-2001 as a Single-Dose CRISPR-Based Treatment for Transthyretin Amyloidosis with Cardiomyopathy

CAMBRIDGE, Mass., March 18, 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 first patient dosed in the global pivotal, Phase 3 MAGNITUDE trial of NTLA-2001. NTLA-2001 is an investigational in vivo CRISPR-based therapy designed as a single-dose treatment to inactivate the TTR gene and thereby prevent the production of TTR protein for the treatment of transthyretin (ATTR) amyloidosis. The MAGNITUDE trial is evaluating the efficacy and safety of NTLA-2001 in patients with ATTR amyloidosis with cardiomyopathy.

“Dosing of the first patient in the MAGNITUDE trial of NTLA-2001 puts us one step closer to bringing a potential one-time gene editing treatment to people living with ATTR amyloidosis,” said Intellia President and Chief Executive Officer John Leonard, M.D. “With multiple sites now enrolling patients, including in the U.S., we are off to a great start to rapidly enroll this landmark study. MAGNITUDE was informed by the compelling interim Phase 1 results reported last year. These data showed that a single-dose treatment of NTLA-2001 resulted in deep and durable reductions of the TTR protein responsible for the clinical consequences of the disease. We look forward to evaluating the efficacy and safety of NTLA-2001 in patients with cardiomyopathy in the pivotal Phase 3 trial. Assuming a positive outcome, it will pave the way for future global marketing applications, ultimately supporting our goal to bring forth a groundbreaking therapy for the ATTR amyloidosis community.”

“The diagnosis of ATTR amyloidosis, a life-threatening condition leading to heart failure and other complications, is rapidly increasing,” said Julian Gillmore, M.D., Ph.D., Professor of Medicine, National Amyloidosis Centre, UCL Division of Medicine, Royal Free Hospital, U.K., and the Phase 3 study’s national coordinating investigator. “We, along with our colleagues at Richmond Pharmacology, are thrilled to be the first to dose a patient in the pivotal trial of NTLA-2001, an in vivo CRISPR-based treatment that offers the potential to dramatically reset the standard of care for people living with this devastating disease. There is remarkable interest from the ATTR amyloidosis patient community for a potential single-dose treatment, and we look forward to contributing to the advancement of novel treatment approaches.”
