CAMBRIDGE, Mass., May 11, 2026 (GLOBE NEWSWIRE) -- Intellia Therapeutics, Inc. (Nasdaq: NTLA), a leading biopharmaceutical company focused on revolutionizing medicine leveraging CRISPR gene editing and other core technologies, today reported business updates and financial results for the first quarter ended March 31, 2026.

“It has been a remarkable start to 2026 for Intellia,” said John Leonard, M.D., Intellia President and Chief Executive Officer. “With lonvo-z, we achieved a historic milestone by presenting the world’s first Phase 3 data for an in vivo gene editing candidate and initiated a rolling BLA submission as we seek to provide a highly differentiated one-time treatment option to people living with HAE. We also recently resumed patient screening for both of our Phase 3 clinical trials in ATTR and strengthened our balance sheet with an underwritten public offering. We look forward to achieving additional important milestones during the remainder of the year.”

Lonvoguran Ziclumeran (Lonvo-z) for Hereditary Angioedema (HAE)

Designed as a one-time treatment that is administered in an outpatient setting, lonvo-z is an in vivo CRISPR gene editing candidate that is intended to inactivate the kallikrein B1 (KLKB1) gene to permanently lower kallikrein and bradykinin levels and to eliminate HAE attacks.

• In April, Intellia announced positive topline results from the global Phase 3 HAELO clinical trial of lonvo-z in HAE.
  • The trial met its primary endpoint. For the six-month efficacy evaluation period (weeks 5 to 28), a one-time infusion of lonvo-z reduced attacks by 87% versus placebo, with a mean monthly attack rate of 0.26 in the lonvo-z arm compared with 2.10 in the placebo arm (p<0.0001).
  • The trial met all of its key secondary endpoints with statistical significance (p<0.0001). These included a 62% rate of patients who were entirely attack free and therapy free in the lonvo-z arm for the six-month efficacy evaluation period, compared with 11% of patients in the placebo arm.
  • Favorable safety and tolerability data were observed for lonvo-z. The most common treatment emergent adverse events (TEAEs) during the primary observation period (infusion through week 28) were infusion-related reactions, headache and fatigue. All TEAEs reported as of the data cutoff (February 10, 2026) were mild or moderate (Grade 1 or Grade 2) and there were no serious adverse events observed in the lonvo-z arm.
  • As of the data cutoff, all patients who received lonvo-z at baseline or in crossover after week 28 remained free from long-term prophylaxis therapy.
    
• Intellia announced in April that it has initiated a rolling biologics license application (BLA) submission to the U.S. Food and Drug Administration (FDA) to seek regulatory approval for lonvo-z. Pursuant to the regenerative medicine advanced therapy (RMAT) designation granted to lonvo-z by the FDA, a rolling BLA allows the company to submit portions of the BLA on an ongoing basis and provides the FDA with an opportunity to accelerate its review. Intellia plans to complete its BLA submission in the second half of 2026 to support a potential U.S. launch of lonvo-z in the first half of 2027.
  
• In the first quarter, Intellia presented several posters at the 2026 American Academy of Allergy, Asthma & Immunology (AAAAI) Annual Meeting. The presentations included three-year follow-up data from patients receiving a one-time 50 milligram dose of lonvo-z and new survey findings assessing the chronic treatment burden and unmet needs among patients living with HAE.
• Additional clinical data from HAELO will be presented at the 2026 European Academy of Allergy and Clinical Immunology Congress (EAACI), taking place June 12-15 in Istanbul, Türkiye (abstract #100217).
  
  

Nexiguran Ziclumeran (Nex-z) for Transthyretin (ATTR) Amyloidosis

Nex-z is an investigational in vivo CRISPR-based therapeutic candidate designed to inactivate the TTR gene in the liver, thereby preventing the production of transthyretin (TTR) protein. Nex-z offers the possibility of halting and reversing disease by driving a deep, consistent and potentially lifelong reduction in TTR protein after a one-time treatment. Intellia leads the development and commercialization of nex-z in collaboration with Regeneron Pharmaceuticals, Inc. (Regeneron).

• In the first quarter, the FDA lifted the clinical holds from the MAGNITUDE and MAGNITUDE-2 Phase 3 clinical trials of nex-z in ATTR amyloidosis with cardiomyopathy (ATTR-CM) and hereditary ATTR amyloidosis with polyneuropathy (ATTRv-PN), respectively. Patient screening activities are advancing in both trials.
• Intellia plans to complete patient enrollment in MAGNITUDE-2 in the second half of 2026.
  
  

Upcoming Events
The company will participate in the following events during the second quarter of 2026:

• Bank of America Securities Health Care Conference, May 12, Las Vegas
• RBC Capital Markets Global Healthcare Conference, May 20, New York
• Jefferies Global Healthcare Conference, June 3, New York
• EAACI Congress, June 12-15, Istanbul, Türkiye
  
  

First Quarter 2026 Financial Results

• Cash Position: Cash, cash equivalents and marketable securities were $517.2 million as of March 31, 2026, compared to $605.1 million as of December 31, 2025. Additionally, in April 2026, the company executed an underwritten public offering of its common stock for approximately $207 million in gross proceeds. The company’s existing cash resources are expected to fund its operations at least into 2028 and well beyond lonvo-z’s anticipated U.S. commercial launch for HAE in the first half of 2027. This guidance excludes all potential commercial revenues from lonvo-z.
• Collaboration Revenue: Collaboration revenue was $15.0 million for the first quarter of 2026, compared to $16.6 million for the first quarter of 2025.
• R&D Expenses: Research and development (R&D) expenses were $80.7 million for the first quarter of 2026, compared to $108.4 million for the first quarter of 2025. The decrease was primarily driven by lower costs for research materials and contracted services, employee-related expenses, and stock-based compensation. Stock-based compensation expense included in R&D expenses was $7.6 million for the first quarter of 2026.
• G&A Expenses: General and administrative (G&A) expenses were $34.8 million for the first quarter of 2026, compared to $29.0 million for the first quarter of 2025. The increase was primarily driven by the ongoing buildout of the company’s commercial infrastructure and higher legal expenses, partially offset by lower stock-based compensation. Stock-based compensation expense included in G&A expenses was $5.9 million for the first quarter of 2026.
• Net Loss: Net loss was $96.2 million for the first quarter of 2026, compared to $114.3 million for the first quarter of 2025.
