Intellia reports positive results for its CRISPR-based treatment
Intellia Therapeutics said Saturday that the first 10 patients to receive a CRISPR-based treatment for hereditary angioedema, a genetic disease, saw their swelling attacks — the condition’s hallmark symptom — virtually eliminated for an average of 20 months and counting.
The attacks were reduced by an average of 98%. One patient has remained attack-free for 26 months. Two patients who suffered particularly frequent attacks, experiencing 14 and 16.8 per month, respectively, have now gone more than 20 months since their last attack.
No patient has had an attack in the last 11 months of follow-up, according to the data presented at the European Academy of Allergy and Clinical Immunology Congress. All side effects were either grade 1 or 2 on a 5-grade scale.
