Phase 2 study results of Ionis' novel antisense treatment for hereditary angioedema to be presented at ACAAI annual meeting
HAE is a rare and potentially fatal autosomal dominant disease that results in recurrent, painful attacks of swelling affecting the hands, feet, limbs, face, abdomen, larynx and trachea. Donidalorsen is an investigational antisense medicine designed to reduce the production of prekallikrein, which plays a key role in the activation of inflammatory mediators associated with acute attacks of HAE. Donidalorsen was developed using Ionis' advanced LIgand-Conjugated Antisense (LICA) technology.
Topline results of the Phase 2 study, reported earlier this year, showed that donidalorsen met its primary and all secondary endpoints, achieving significant reductions in the number of attacks suffered by patients with hereditary angioedema (HAE) compared to placebo. These data support advancing donidalorsen into Phase 3 development, which Ionis plans to initiate this year.
