Intellia's CRISPR Gene Therapy Shows 98% Reduction in HAE Attacks After Three Years
- Intellia Therapeutics reported three-year follow-up data showing lonvoguran ziclumeran achieved a 98% mean reduction in monthly hereditary angioedema attack rates across all 10 Phase 1 patients.
- All patients remained attack-free and treatment-free for a median of 23 months, demonstrating the potential for lonvo-z to become the first one-time therapy for HAE patients.
- The company's Phase 3 HAELO trial completed screening ahead of schedule, with results expected in the first half of 2026 and a planned U.S. launch in 2027.
- The CRISPR-based therapy targets the KLKB1 gene to prevent HAE attacks and has received multiple regulatory designations including FDA Orphan Drug and RMAT status.
