CAMBRIDGE, Mass., Aug. 08, 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 second quarter ended June 30, 2024.

“We are delighted to report the Phase 2 study of NTLA-2002 met its primary efficacy and all secondary endpoints at both dose levels and, importantly, provided clear support for advancing the 50 mg dose into the pivotal Phase 3 trial in patients with hereditary angioedema,” said Intellia President and Chief Executive Officer John Leonard, M.D. “Based on these positive results and our recent successful end-of-Phase 2 meeting with the FDA, we see a clear path to initiating the Phase 3 trial in the coming months. We look forward to presenting the detailed Phase 2 results at a medical meeting in the fourth quarter as we continue to advance what we believe could be a functional cure for hereditary angioedema. With three pivotal Phase 3 trials and our first gene insertion trial expected to be active by year-end, Intellia is closer than ever to transforming the future of medicine with our one-time, in vivo gene editing therapies.”

Second Quarter 2024 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 announced today positive topline results from the Phase 2, randomized, double-blind, placebo-controlled study of NTLA-2002 in patients with HAE. The clinical trial met its primary efficacy and all secondary endpoints in the 16-week primary observation period, with a single 25 mg or 50 mg dose leading to deep reductions in attacks. No new safety findings were observed. Intellia has selected the 50 mg dose for further evaluation in the global pivotal Phase 3 trial based upon the greater number of patients with complete attack elimination and greater kallikrein protein reduction compared to the 25 mg dose observed in the Phase 2 study, which is consistent with the previously reported Phase 1 results. The Company plans to present the detailed Phase 2 data at an upcoming medical meeting in the fourth quarter of this year.
  • The Company announced today the successful completion of an end-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) supporting its Phase 3 plans for NTLA-2002. The Phase 3 study is on track to initiate in the second half of 2024, subject to regulatory feedback.
  • In June, Intellia presented positive long-term data from the ongoing Phase 1 study. Eight of 10 patients remained completely attack-free following the 16-week primary observation period. These patients have experienced ongoing attack-free durations of greater than 18 months after a single-dose treatment, with the longest ongoing individual attack-free duration reaching over 26 months. Across all patients, NTLA-2002 led to a 98% mean reduction in monthly HAE attack rate. Consistent with previously reported results, NTLA-2002 was well-tolerated, with the majority of adverse events being mild in severity through the latest follow-up. These interim data were presented at the European Academy of Allergy and Clinical Immunology (EAACI) Congress 2024 in Valencia, Spain.

Transthyretin (ATTR) Amyloidosis

• NTLA-2001: NTLA-2001, now known as nexiguran ziclumeran (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. 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):
    • The pivotal Phase 3 MAGNITUDE trial is enrolling rapidly and continues to track ahead of the Company’s initial projections. During the second quarter, the Company received approval for its application under the new European Union Clinical Trials Regulation, which enables the Phase 3 trial to proceed in Denmark, Germany, France, Italy, Spain and Sweden. The MAGNITUDE trial of NTLA-2001 is now cleared by regulatory agencies in over 12 countries and actively enrolling at over 35 sites globally.
  • Hereditary ATTR Amyloidosis with Polyneuropathy (ATTRv-PN):
    • The Company plans to initiate a pivotal Phase 3 trial of NTLA-2001 as a single-dose treatment for ATTRv-PN by year-end. As previously announced, the study is expected to be a small, placebo-controlled trial conducted at ex-U.S. sites with approximately 50 ATTRv-PN patients.
  • Intellia plans to present updated data from the ongoing Phase 1 study in the second half of 2024.

Alpha-1 Antitrypsin Deficiency (AATD)-Associated Lung Disease

• NTLA-3001: NTLA-3001 is a 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 the wild-type SERPINA1 gene, which encodes the alpha-1 antitrypsin (AAT) protein, with the potential to restore permanent expression of fully functional AAT protein to normal levels after a single dose. This is Intellia’s first wholly owned gene insertion program.
  • In July, Intellia announced the authorization of its Clinical Trial Application by the United Kingdom’s Medicines and Healthcare products Regulatory Agency (MHRA) to initiate a first-in-human study of NTLA-3001. Intellia expects to dose the first patient in the Phase 1/2 study of NTLA-3001 in the second half of 2024.

In Vivo Platform Expansion

• In June, Intellia presented positive clinical proof-of-concept data that redosing with CRISPR, utilizing the Company’s proprietary non-viral, LNP-based delivery platform, enabled an additive pharmacodynamic effect. In the three patients who previously received the lowest dose of 0.1 mg/kg in the Phase 1 dose-escalation study of NTLA-2001, follow-on dosing with a 55 mg dose of NTLA-2001 led to a deeper protein reduction. Median reduction in serum TTR was 90% at day 28 after redosing. The corresponding reduction from original baseline levels was a 95% median reduction in serum TTR. NTLA-2001 was generally well tolerated across all patients after receiving the follow-on dose. While redosing is not planned for the NTLA-2001 program in ATTR amyloidosis, a redosing option could be an important advantage of Intellia’s LNP-based delivery platform for future investigational therapies where a target additive effect is desired. These data were presented at the Peripheral Nerve Society (PNS) Annual Meeting in Montreal, Canada.
• Intellia is expanding the range of diseases that can be targeted with its CRISPR-based technologies by deploying new editing and delivery innovations. This includes advancing gene editing programs in five different tissues outside the liver, either independently or in collaboration with partners. These research and preclinical programs are targeting diseases that originate in the bone marrow, brain, muscle, lung and eye, which, if successful, could dramatically expand the opportunities for CRISPR-based treatments.

Ex Vivo Program Updates

• Intellia is advancing multiple 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 avoids both T cell- and NK cell-mediated rejection in preclinical models, a key unsolved challenge with other investigational allogeneic approaches. Cell therapies engineered with Intellia’s allogeneic platform, combined with edits to enhance cell function, offer a new approach to target both hematological and solid tumors.

Corporate Updates

• In June, Intellia announced the appointment of Brian Goff to its board of directors. Mr. Goff joins the board of directors with over three decades of commercialization, operations and sales and marketing experience at leading biopharmaceutical companies.
• In June, Intellia announced the appointment of Edward Dulac as Executive Vice President, Chief Financial Officer, and Treasurer, effective July 22, 2024. Mr. Dulac succeeds Glenn Goddard, who stepped down from his role effective June 30, 2024. Mr. Dulac joins Intellia with more than 20 years of combined finance, business development and corporate strategy experience.
