  • Oral presentation to include additional durability data from patients treated with NTLA-2001, the first-ever systemically administered in vivo CRISPR investigational therapy

  • Presentation to include data supporting fixed dose selection in the ongoing single-dose expansion cohort of polyneuropathy arm

CAMBRIDGE, Mass., June 08, 2022 (GLOBE NEWSWIRE) -- Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading genome editing company focused on developing potentially curative therapies leveraging CRISPR-based technologies, today announced that interim clinical data from the Phase 1 study of NTLA-2001, an investigational therapy in development for the treatment of transthyretin (ATTR) amyloidosis, will be shared in an oral presentation at the European Association for the Study of the Liver’s International Liver Congress™ 2022, taking place June 22 – 26 in London.

“We are pleased to be presenting longer-term, follow-up data from the first-in-human study of NTLA-2001, which is designed to potentially halt progression and reverse ATTR amyloidosis,” said Intellia President and Chief Executive Officer John Leonard, M.D. “We look forward to sharing interim data we believe demonstrates the potential of our CRISPR-based investigational therapy to be a single-dose treatment that provides a deep and durable response.”

The presentation will include new data from the ongoing Phase 1 study evaluating NTLA-2001 in people living with hereditary ATTR amyloidosis with polyneuropathy (ATTRv-PN). These include additional results from all four dose-escalation cohorts in Part 1, highlighting the durability of response after a single dose of NTLA-2001. Data supporting the fixed dose selection for Part 2, the single-dose expansion cohort of the polyneuropathy arm, will also be presented.

The presentation will build upon interim data presented in February, which showed significant reductions in serum TTR levels from baseline in a dose-dependent manner in 15 patients with ATTRv-PN. At the highest dose tested, 1.0 mg/kg, the mean and maximum serum TTR reductions were 93% and 98%, respectively, by day 28 across the six patients treated. The Company also previously announced it is now evaluating a fixed dose of 80 mg in Part 2 of the Phase 1 study, which is expected to deliver a similar exposure to the 1.0 mg/kg dose in the ATTRv-PN target population, and that the first patient has been dosed in the expansion cohort in the polyneuropathy arm. Intellia also continues to dose patients in the cardiomyopathy arm of the Phase 1 study, which is evaluating NTLA-2001 in dose-escalation cohorts of people with ATTR amyloidosis with cardiomyopathy (ATTR-CM).

Presentation Details

Title: In vivo CRISPR/Cas9 editing of the TTR gene with NTLA-2001 in patients with transthyretin amyloidosis – dose selection considerations

Session: Rare liver diseases (including paediatric and genetic)

Date and Time: Friday, June 24, 2022 from 10:00-11:30 a.m. BST

Presenter: Dr. Edward J. Gane, MBChB, MD, FRACP, MNZM, Professor of Medicine at the University of Auckland, New Zealand and Chief Hepatologist, Transplant Physician and Deputy Director of the New Zealand Liver Transplant Unit at Auckland City Hospital, the trial’s national investigator in New Zealand

Intellia Therapeutics Investor Event and Webcast Information

Intellia will host a live webcast on Friday, June 24, 2022 at 8:00 a.m. ET to review the presented data. To join the webcast, please visit this link, or the Events and Presentations page of the Investors & Media section of the company’s website at www.intelliatx.com. A replay of the webcast will be available on Intellia’s website for at least 30 days following the call.

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.

About NTLA-2001
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 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). Visit clinicaltrials.gov (NCT04601051) for more details.

About Intellia Therapeutics
Intellia Therapeutics, a leading clinical-stage genome editing company, is developing novel, potentially curative therapeutics leveraging CRISPR-based technologies. To fully realize the transformative potential of CRISPR-based technologies, 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 genome editing to create new classes of genetic medicine.
