Intellia Therapeutics has achieved significant results in a Phase 3 trial for its CRISPR gene editing therapy, lonvoguran ziclumeran (lonvo-z), aimed at treating hereditary angioedema (HAE). This therapy reduced HAE attacks by 87% and allowed 62% of patients to be attack-free without ongoing medication over a six-month period. The therapy functions by silencing the KLKB1 gene, thus providing a durable solution against the disease. With favorable safety results, a biologics license application to the FDA is imminent, targeting a 2027 market launch.
