Intellia Therapeutics Announces Expansion of Ongoing Phase 1 Study of NTLA-2001 to Include Adults with Transthyretin Amyloidosis with Cardiomyopathy (ATTR-CM)
CAMBRIDGE, Mass., Nov. 22, 2021 (GLOBE NEWSWIRE) -- Intellia Therapeutics, Inc. (NASDAQ:NTLA) announced today that the United Kingdom Medicines and Healthcare products Regulatory Agency (MHRA) has approved a protocol amendment for the Company’s ongoing Phase 1 study of NTLA-2001 to include patients with ATTR amyloidosis with cardiomyopathy (ATTR-CM). The study of NTLA-2001 now includes patients with ATTR-CM to be enrolled in new dose-escalation and expansion cohorts. The inclusion of the ATTR-CM patient population is in addition to the original Phase 1 study population, which is currently evaluating NTLA-2001 in patients with ATTR amyloidosis with polyneuropathy (ATTRv-PN).
The first investigational therapy of its kind, NTLA-2001 is an in vivo CRISPR/Cas9-based genome editing candidate being developed as a single-dose treatment for transthyretin (ATTR) amyloidosis. It is designed to inactivate the TTR gene in liver cells to prevent the production of transthyretin (TTR) protein and is being developed to potentially be the first single-dose ATTR amyloidosis treatment to not only halt but also reverse disease progression in both ATTRv-PN and ATTR-CM patients. NTLA-2001 has received orphan drug designation for the treatment of ATTR amyloidosis by both the European Commission and the U.S. FDA.
“ATTR amyloidosis is a chronic, fatal disease that can impact different organs and tissues within the body, often manifesting as either polyneuropathy or cardiomyopathy. At Intellia, our goal is to develop a potentially curative treatment that could benefit as many patients living with this disease as possible,” said Intellia President and Chief Executive Officer John Leonard, M.D. “We have already seen promising interim data supporting the ability of NTLA-2001 to significantly reduce serum TTR levels in ATTR patients with polyneuropathy. We are excited to now expand our Phase 1 study of NTLA-2001 to include ATTR patients with cardiomyopathy in order to advance this potentially first-of-its-kind, single-dose treatment for more patients.”
The protocol amendment to the Phase 1 study allows for enrollment of up to 36 adults in the United Kingdom with either hereditary ATTR-CM (ATTRv-CM) or wild-type cardiomyopathy (ATTRwt-CM), and New York Heart Association Class I – III heart failure, across the two-part study. The trial’s primary objectives are to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of NTLA-2001, which will include the measurement of serum TTR levels following a single intravenous infusion. The secondary objectives are to evaluate the efficacy of NTLA-2001 on clinical measures of cardiac disease in ATTR-CM patients.
In June 2021, Intellia and its collaborator Regeneron announced positive interim clinical results from the first two cohorts of this study. These results, which were subsequently published in the New England Journal of Medicine, represented the first-ever clinical data supporting in vivo CRISPR genome editing in humans.

About Intellia Therapeutics
Intellia Therapeutics, a leading clinical-stage genome editing company, is developing novel, potentially curative therapeutics using CRISPR/Cas9 technology. To fully realize the transformative potential of CRISPR/Cas9, Intellia is pursuing two primary approaches. The company’s in vivo programs use intravenously administered CRISPR as the therapy, in which proprietary delivery technology enables highly precise editing of disease-causing genes directly within specific target tissues. Intellia’s ex vivo programs use CRISPR to create the therapy by using engineered human cells to treat cancer and autoimmune diseases. Intellia’s deep scientific, technical and clinical development experience, along with its robust intellectual property portfolio, have enabled the company to take a leadership role in harnessing the full potential of CRISPR/Cas9 to create new classes of genetic medicine.
