NTLA Intellia Therapeutics Inc

Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading clinical-stage gene editing company focused on revolutionizing medicine with CRISPR-based therapies, today announced the first patient has been dosed in the global Phase 3 study of NTLA-2002 for the treatment of hereditary angioedema (HAE). NTLA-2002 is a wholly owned investigational in vivo CRISPR-based therapy in development as a single-dose treatment for this potentially life-threatening disease. Intellia expects to complete enrollment in the second half of 2025 and submit a biologics license application (BLA) in 2026 to support the Company’s plans for a U.S. launch in 2027.

“We are pleased to have initiated dosing in the HAELO Phase 3 study as we are in our final lap of clinical development for NTLA-2002,” said Intellia President and Chief Executive Officer John Leonard, M.D. “With the promising data we’ve presented thus far, we believe patients could achieve independence from both HAE attacks and medications required to treat this disease. We look forward to presenting longer-term data from the ongoing Phase 1/2 study later this year highlighting the durability of effect of NTLA-2002.”

"We are excited to have treated the first patient in the U.S. with a new generation of therapy that could potentially provide patients with lifelong relief from the primary symptoms of HAE,” commented Dr. Joshua Jacobs, Medical Director, Allergy and Asthma Clinical Research, Inc.

About the HAELO StudyThe pivotal Phase 3 HAELO clinical trial is a randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of NTLA-2002 in 60 adults with Type I or Type II HAE. Patients will be randomized 2:1 to receive a single 50 mg infusion of NTLA-2002 or placebo. Patients randomized to the placebo arm will be eligible for optional crossover to NTLA-2002 at week 28. Key endpoints include the number of HAE attacks and the number of patients who achieve attack-free status from week 5 through week 28. For more information on HAELO (NCT06634420), please visit clinicaltrials.gov.

About NTLA-2002Based on Nobel-prize winning CRISPR/Cas9 technology, NTLA-2002 has the potential to become the first one-time treatment for hereditary angioedema (HAE). NTLA-2002 is designed to prevent HAE attacks by inactivating the kallikrein B1 (KLKB1) gene, which encodes for prekallikrein, the kallikrein precursor protein. NTLA-2002 has received five notable regulatory designations, including Orphan Drug and RMAT Designation by the U.S. Food and Drug Administration, the Innovation Passport by the U.K. Medicines and Healthcare products Regulatory Agency (MHRA), Priority Medicines (PRIME) Designation by the European Medicines Agency, as well as Orphan Drug Designation by the European Commission.

About Hereditary AngioedemaHereditary angioedema (HAE) is a rare, genetic disease characterized by severe, recurring and unpredictable inflammatory attacks in various organs and tissues of the body, which can be painful, debilitating and life-threatening. It is estimated that one in 50,000 people are affected by HAE. Although there is no known cure for HAE, there are preventative and on-demand treatment options to help manage the condition, including long- and short-term prophylaxis used to prevent swelling attacks. Current treatment options often include life-long therapies, which may require chronic intravenous (IV) or subcutaneous (SC) administration as often as twice per week or daily oral administration to ensure constant pathway suppression for disease control. Despite chronic administration, breakthrough attacks still occur. Kallikrein inhibition is a clinically validated strategy for the preventive treatment of HAE attacks.
