Phase 2 Experimental Study Arm

Experimental

Participants randomized to NTLA-2002 (2 dose levels), will receive a single dose of NTLA-2002 on Day 1 and will then be followed for 104 weeks. Primary observation period is 16 weeks.

干预措施: Biological NTLA-2002 (Biological)

Phase 2 Placebo Comparator Study Arm

Placebo Comparator

干预措施: Normal Saline IV Administration (Other)

Placebo Crossover and Follow-On Dosing Substudy Arm

Experimental

Participants assigned to this Substudy Arm (participants who previously received either 25mg or placebo only) will have the opportunity to receive a single dose of NTLA-2002 (50mg) and will then be followed for 52 weeks.

干预措施: Biological NTLA-2002 (Biological)

NTLA-2002 Demonstrates Significant Reduction in Angioedema Attacks via CRISPR-Cas9 Gene Editing- A single dose of NTLA-2002, an investigational CRISPR-Cas9 gene-editing therapy, significantly reduced angioedema attacks in patients with hereditary angioedema (HAE). - The Phase 2 trial data showed a dose-related reduction in plasma kallikrein levels, with the 50-mg dose reducing kallikrein by 86% from baseline. - A substantial portion of participants, particularly in the 50-mg group (73%), remained attack-free throughout the 16-week observation period without needing additional intervention. - NTLA-2002 was generally well-tolerated, with mostly mild-to-moderate adverse events, supporting its further investigation in a Phase 3 trial.last yearNTLA-2002 Shows Promise as Functional Cure for Hereditary Angioedema in Phase 2 Trial- Phase 2 trial results show NTLA-2002 significantly reduces swelling attacks in hereditary angioedema (HAE) patients, with up to 80% attack reduction at the 50 mg dose. - A substantial portion of patients receiving NTLA-2002 experienced complete attack-free periods, with some remaining attack-free through the latest assessments. - NTLA-2002 was generally well-tolerated, with no serious side effects reported, suggesting a favorable safety profile for this gene-editing therapy. - Intellia Therapeutics has initiated a Phase 3 trial based on these positive results, potentially redefining the treatment paradigm for HAE.last yearIntellia Therapeutics Initiates Phase 3 Trial of NTLA-2002 for Hereditary Angioedema- Intellia Therapeutics has dosed the first patient in its Phase 3 HAELO trial evaluating NTLA-2002 for hereditary angioedema (HAE). - The HAELO trial is a global, randomized, double-blind, placebo-controlled study involving 60 adults with Type I or Type II HAE. - NTLA-2002, a single-dose CRISPR-based therapy, targets the _KLKB1_ gene to reduce plasma kallikrein activity and prevent HAE attacks. - Intellia anticipates completing enrollment in the second half of 2025 and plans for a potential U.S. launch in 2027, pending regulatory approval.last year
