CARLSBAD, Calif., Oct. 3, 2024 /PRNewswire/ -- Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) announced today that it will present new three-year data from the Phase 2 open-label extension (OLE) study as well as additional results from the pivotal Phase 3 OASIS and OASISplus studies of donidalorsen, the company's investigational RNA-targeted prophylactic medicine for hereditary angioedema (HAE). Results will be presented at the 2024 American College of Allergy, Asthma & Immunology (ACAAI) Annual Scientific Meeting in Boston, Massachusetts.
New data at ACAAI demonstrate donidalorsen significantly reduced HAE attacks, translating to high levels of disease control and significant and clinically meaningful improvements in quality-of-life across multiple measures in a vast majority of patients, sustained up to three years. Presentations include:
Ionis previously reported positive results from the Phase 3 OASIS-HAE and OASISplus studies. Data from both studies were presented at the 2024 European Academy of Allergy and Clinical Immunology (EAACI) Annual Congress in Valencia, Spain and results from OASIS-HAE were published in The New England Journal of Medicine. The company also previously reported positive two-year results from the Phase 2 OLE study last year.
About Hereditary Angioedema (HAE)
HAE is a rare and potentially life-threatening genetic condition that involves recurrent attacks of severe swelling (angioedema) in various parts of the body, including the hands, feet, genitals, stomach, face and/or throat. HAE is estimated to affect more than 20,000 patients in the U.S. and Europe. In the U.S., doctors frequently use prophylactic treatment approaches to prevent and reduce the severity of HAE attacks in patients.
About Donidalorsen
Donidalorsen is an investigational RNA-targeted medicine designed to target prekallikrein (PKK), which plays an important role in activating inflammatory mediators associated with acute attacks of hereditary angioedema (HAE). By reducing the production of PKK, donidalorsen could be an effective prophylactic approach to preventing HAE attacks, if approved.
Donidalorsen is an investigational medicine that has not been approved for the treatment of any disease by regulatory authorities.
