CAMBRIDGE, Mass., Feb. 22, 2024 (GLOBE NEWSWIRE) — Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading clinical-stage gene editing company focused on revolutionizing medicine with CRISPR-based therapies, today reported operational highlights and financial results for the fourth quarter and year ended December 31, 2023.

“We’re off to a very strong start in 2024 as we execute against our strategic priorities to realize the full potential of CRISPR-based gene editing,” said Intellia President and Chief Executive Officer John Leonard, M.D. “We are focused on rapidly enrolling patients in the pivotal Phase 3 MAGNITUDE trial of NTLA-2001 for the treatment of ATTR amyloidosis with cardiomyopathy and expect to dose the first patient in the first quarter of this year. We also remain on track to begin the Phase 3 trial for our second in vivo CRISPR-based therapy, NTLA-2002 for hereditary angioedema, later in the year. At the same time, we continue to expand both the technical approaches for CRISPR-based therapies, as well as the range of diseases they can potentially address. We plan to initiate two first-in-human studies for product candidates leveraging our modular gene insertion platform to produce a deficient protein – one wholly owned program focused on alpha-1 antitrypsin deficiency-associated lung disease and, together with Regeneron, a second program focused on hemophilia B. Finally, we are progressing our editing capabilities, including DNA writing, and applying them to diseases that originate outside of the liver. We announced last week a new collaboration with ReCode Therapeutics to advance novel gene editing treatments directly to the lung in patients with cystic fibrosis. These pipeline and platform efforts move us closer to setting a new standard of care for people living with serious diseases and expanding Intellia’s impact as the leading gene editing company.”

Fourth Quarter 2023 and Recent Operational Highlights

Transthyretin (ATTR) Amyloidosis

• NTLA-2001: NTLA-2001 is an investigational in vivo CRISPR-based therapy designed to inactivate the TTR gene in the liver and thereby prevent the production of transthyretin (TTR) protein for the treatment of ATTR amyloidosis. NTLA-2001 offers the possibility of halting and reversing the disease by driving a deep, consistent and potentially lifelong reduction in TTR protein after a single dose. Intellia leads development and commercialization of NTLA-2001 in collaboration with Regeneron.

• • ATTR Amyloidosis with Cardiomyopathy (ATTR-CM):
    • Intellia is actively enrolling patients, including in the U.S., in the pivotal Phase 3 MAGNITUDE trial. The Company is on track to dose the first patient in Q1 2024 and continues to open new clinical sites.
  • Hereditary ATTR Amyloidosis with Polyneuropathy (ATTRv-PN):
    • Intellia is actively preparing for a global pivotal Phase 3 study of NTLA-2001 for the treatment of ATTRv-PN.
  • The Company plans to present updated data from the ongoing Phase 1 study in 2024.

Hereditary Angioedema (HAE)

• NTLA-2002: NTLA-2002 is a wholly owned, investigational in vivo CRISPR-based therapy designed to knock out the KLKB1 gene in the liver, with the goal of lifelong control of HAE attacks after a single dose.
  • Intellia plans to initiate the global pivotal Phase 3 study, including U.S. patients, in the second half of 2024, subject to regulatory feedback.
  • As previously announced in January, Intellia completed enrollment and dosing in the Phase 2 portion of the Phase 1/2 study in adults with HAE. The Company plans to present updated data from the Phase 1 and new data from the Phase 2 portion in 2024.
  • In January, the Company announced that positive interim results from the Phase 1 portion of the Phase 1/2 study of NTLA-2002 were published in the New England Journal of Medicine (NEJM). The reported data showed that a single dose of NTLA-2002 led to a 95% mean reduction in monthly HAE attack rate across all 10 patients in the Phase 1 portion. NTLA-2002 was well tolerated at all dose levels. The most frequent adverse events reported were mild, transient infusion-related reactions and fatigue.
  • During the fourth quarter of 2023, Intellia received Priority Medicines (PRIME) designation from the European Medicines Agency and orphan drug designation from the European Commission for NTLA-2002.

In Vivo Targeted Gene Insertion

• NTLA-3001 for Alpha-1 Antitrypsin Deficiency (AATD)-Associated Lung Disease: NTLA-3001 is a wholly owned, first-in-class CRISPR-mediated in vivo targeted gene insertion development candidate for the treatment of AATD-associated lung disease. It is designed to precisely insert a healthy copy of the SERPINA1 gene, which encodes the alpha-1 antitrypsin (A1AT) protein, with the potential to restore permanent expression of functional A1AT protein to therapeutic levels after a single dose.
  • In December 2023, Intellia submitted a Clinical Trial Application (CTA) to initiate a first-in-human, Phase 1 study of NTLA-3001. The Company plans to dose the first patient in 2024.
• Hemophilia B: In February, Regeneron and Intellia announced the clearance by the U.S. Food and Drug Administration of its investigational new drug application to initiate a clinical trial of its investigational in vivo CRISPR-based Factor 9 gene insertion program for people living with hemophilia B. A Phase 1, first-in-human study is expected to begin in mid-2024. Regeneron leads development and commercialization of hemophilia A and B programs in collaboration with Intellia.

In Vivo Platform Expansion Including to Tissues Outside of the Liver

• In February, Intellia and ReCode announced a strategic collaboration to develop novel genomic medicines for the treatment of cystic fibrosis (CF). The collaboration will leverage Intellia’s proprietary CRISPR-based gene editing platform, including its DNA writing technology, and ReCode’s proprietary Selective Organ Targeting (SORT) lipid nanoparticle delivery platform to precisely correct one or more CF disease-causing gene mutations.

• In October 2023, Intellia and Regeneron announced an expanded research collaboration to develop additional in vivo CRISPR-based gene editing therapies focused on neurological and muscular diseases.
• In October 2023, Regeneron exercised its option to extend the existing technology collaboration term with Intellia for two years. The technology collaboration term now extends to April 2026, and Intellia will receive a $30 million payment due in April 2024.

Ex Vivo Program Updates

• Intellia is advancing multiple preclinical programs, wholly owned and in collaboration with partners, utilizing its allogeneic platform for the treatment of immuno-oncology and autoimmune diseases. The Company’s proprietary allogeneic cell engineering platform is designed to avoid both T cell- and NK cell-mediated rejection, a key unsolved challenge with other investigational allogeneic approaches.

Upcoming Events

The Company will participate in the following events in March:

• TD Cowen 44^th Annual Health Care Conference, March 4, Boston
• Leerink Global Biopharma Conference, March 12, Miami
• Barclays Global Healthcare Conference, March 13, Miami

Fourth Quarter and Full-Year 2023 Financial Results

• Cash Position: Cash, cash equivalents and marketable securities were $1.0 billion as of December 31, 2023, compared to $1.3 billion as of December 31, 2022. The decrease was driven by cash used to fund operations of $448.8 million. The decrease was offset in part by $119.8 million of net equity proceeds from the Company’s “At the Market” (ATM) program, $49.8 million of interest income, $18.7 million of reimbursement from its collaborators, and $10.5 million in proceeds from employee-based stock plans. The cash position is expected to fund operations into mid-2026.
• Collaboration Revenue: Collaboration revenue decreased by $15.5 million to negative $1.9 million during the fourth quarter of 2023, compared to $13.6 million during the fourth quarter of 2022. This decrease was mainly driven by a $10.3 million one-time revenue recognition adjustment related to Regeneron extending the technology collaboration to April 2026. Intellia will receive a $30.0 million payment due in April 2024 as part of the Regeneron extension.
• R&D Expenses: Research and development expenses increased by $9.0 million to $109.0 million during the fourth quarter of 2023, compared to $100.0 million during the fourth quarter of 2022. This increase was primarily driven by the advancement of our lead programs and personnel growth to support these programs. Stock-based compensation expense included in research and development expenses was $21.7 million for the fourth quarter of 2023.
• G&A Expenses: General and administrative expenses increased by $5.4 million to $29.0 million during the fourth quarter of 2023, compared to $23.6 million during the fourth quarter of 2022. This increase was primarily related to an increase in stock-based compensation of $4.3 million. Stock-based compensation expense included in general and administrative expenses was $13.3 million for the fourth quarter of 2023.
• Net Loss: The Company’s net loss was $132.2 million for the fourth quarter of 2023, compared to $113.4 million during the fourth quarter of 2022.
