CAMBRIDGE, Mass., May 08, 2025 (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 first quarter ended March 31, 2025.

“Intellia is full steam ahead and making excellent progress across its clinical programs,” said Intellia President and Chief Executive Officer John Leonard, M.D. “Two key achievements in the first quarter were dosing the first patients in two of our Phase 3 studies: the HAELO study for hereditary angioedema and the MAGNITUDE-2 study for hereditary ATTR amyloidosis with polyneuropathy. Additionally, our Phase 3 MAGNITUDE study for ATTR with cardiomyopathy continues to enroll rapidly. Upcoming catalysts include longer-term data from the ongoing Phase 1 study of NTLA-2002 at the upcoming EAACI Congress in addition to updated data from the Phase 2 study of NTLA-2002 and longer-term Phase 1 data of nex-z in the second half of 2025.”

First Quarter 2025 and Recent Operational Highlights

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 will present additional data from the ongoing Phase 1/2 study in an oral presentation at the European Academy of Allergy and Clinical Immunology (EAACI) Congress 2025 on Sunday, June 15 in Glasgow, United Kingdom. The presentation will include longer-term durability data from patients in the Phase 1 portion of the Phase 1/2 study.
  • Enrollment is progressing in the global Phase 3 HAELO study and the Company expects to complete enrollment in the third quarter of 2025.
  • Intellia expects to present new and longer-term data from the Phase 2 portion of the ongoing Phase 1/2 study in the second half of 2025. The data will include patients who initially received a 25 mg dose or placebo and were subsequently given the 50 mg dose of NTLA-2002 selected for the Phase 3 study.
  • The Company is on track to submit a Biologics License Application (BLA) in the second half of 2026.

Transthyretin (ATTR) Amyloidosis

• Nexiguran ziclumeran (nex-z, also known as NTLA-2001): Nex-z is an investigational in vivo CRISPR-based therapy designed to inactivate the TTR gene in liver cells, thereby preventing the production of transthyretin (TTR) protein for the treatment of ATTR amyloidosis. Nex-z 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. Nex-z has been generally well tolerated across all patients and at all dose levels tested. The most common treatment-related adverse events have been mild or moderate infusion reactions; all patients were able to receive the intended dose of nex-z. Intellia leads development and commercialization of nex-z in collaboration with Regeneron Pharmaceuticals, Inc. 
  • ATTR Amyloidosis with Cardiomyopathy (ATTR-CM):
    • In March, Intellia announced the U.S. Food and Drug Administration (FDA) granted Regenerative Medicine Advanced Therapy (RMAT) to nex-z for the treatment of ATTR-CM.
    • Enrollment in the global Phase 3 MAGNITUDE trial is progressing ahead of the Company’s target projections and anticipates enrollment to exceed 550 total patients by year-end.
  • Hereditary ATTR Amyloidosis with Polyneuropathy (ATTRv-PN):
    • In April, the Company announced the first patient was randomized and dosed with nex-z in the global Phase 3 MAGNITUDE-2 study. Intellia expects enrollment to be completed in 2026.
  • In May, the Company will present data at the European Society of Cardiology Heart Failure (ESC-HF) Congress and Peripheral Nerve Society (PNS) Annual Meeting. At ESC-HF, Intellia will show wildtype vs. variant data in patients with ATTR-CM. At PNS, the Company will present interim Phase 1 extended data in patients with ATTRv-PN.
  • Intellia expects to present longer-term data from both ATTR-CM and ATTRv-PN patients in the Phase 1 study in the second half of 2025. The data will include updated measures of clinical efficacy and safety.

Platform Update

• Intellia is pioneering novel technologies, such as CRISPR-based gene editing technologies and lipid nanoparticle (LNP) delivery technologies, to create highly differentiated, future in vivo and ex vivo product candidates. The Company’s proprietary platform technologies are being researched and developed to expand therapeutics opportunities to support the mission of transforming lives of people with severe diseases, including the possibility of curative genome editing therapeutics.

Upcoming Events

The Company will participate in the following events during the second quarter of 2025:

• Bank of America Securities Health Care Conference, May 13, Las Vegas
• ESC Heart Failure Congress, May 17, Belgrade
• PNS Annual Meeting, May 18, Edinburgh
• RBC Capital Markets Global Healthcare Conference, May 21, New York
• EAACI Congress, June 15, Glasgow

First Quarter 2025 Financial Results

• Cash Position: Cash, cash equivalents and marketable securities were $707.1 million as of March 31, 2025, compared to $861.7 million as of December 31, 2024. The decrease in cash, cash equivalents and marketable securities was primarily driven by first quarter operations and approximately $51 million of non-recurring cash payments associated with the Company’s previously announced portfolio prioritization, workforce reduction, and real estate consolidation. The Company’s cash, cash equivalents and marketable securities as of March 31, 2025 are expected to fund operations into the first half of 2027.
• Collaboration Revenue: Collaboration revenue was $16.6 million during the first quarter of 2025, compared to $28.9 million during the first quarter of 2024. The $12.3 million decrease was mainly driven by a decrease in collaboration revenue under the AvenCell license and collaboration agreement.
• R&D Expenses: Research and development (R&D) expenses were $108.4 million during the first quarter of 2025, compared to $111.8 million during the first quarter of 2024. The $3.4 million decrease was primarily driven by employee-related expenses, stock-based compensation, research materials and contracted services offset by an increase in the advancement of our lead programs. Stock-based compensation expense included in R&D expenses was $12.6 million for the first quarter of 2025.
• G&A Expenses: General and administrative (G&A) expenses were $29.0 million during the first quarter of 2025, compared to $31.1 million during the first quarter of 2024. The $2.1 million decrease was primarily related to lower employee-related expenses due to a workforce reduction in January 2025 and lower stock-based compensation, partially offset by increases related to severance expenses recorded in the first quarter. Stock-based compensation expense included in G&A expenses was $9.2 million for the first quarter of 2025.
• Net Loss: Net loss was $114.3 million for the first quarter of 2025, compared to $107.4 million during the first quarter of 2024.
