Results demonstrate the long-term durability and safety of DAWNZERA, including new data from patients who were followed for one year in the ongoing OASISplus open-label extension (OLE) and switch cohorts, as well as new four-year results from the Phase 2 OLE study.\n<\/p>\n<p>\nDAWNZERA was recently <a rel=\"nofollow\" href=\"https:\/\/cts.businesswire.com\/ct\/CT?id=smartlink&amp;url=https%3A%2F%2Fir.ionis.com%2Fnews-releases%2Fnews-release-details%2Fdawnzeratm-donidalorsen-approved-us-first-and-only-rna-targeted&amp;esheet=54353286&amp;newsitemid=20251105648807&amp;lan=en-US&amp;anchor=approved&amp;index=2&amp;md5=bf1f47824589475d9adb3ea56aa37c3c\">approved<\/a> by the U.S. Food and Drug Administration for prophylaxis to prevent attacks of HAE in adult and pediatric patients 12 years of age and older.\n<\/p>\n<p>\n\u201cThese new long-term data support our belief that DAWNZERA, which is now available to people living with HAE in the U.S., is well-positioned to transform the treatment paradigm for HAE,\u201d said Kenneth Newman, M.D., senior vice president, clinical development, Ionis. \u201cThe latest results from across our clinical studies support the strong and durable efficacy and safety profile of DAWNZERA. Presentations at the congress offer patients and physicians valuable insights to support informed treatment decisions, including when transitioning to DAWNZERA from a previous prophylactic therapy.\u201d\n<\/p>\n<p>\nThe OASISplus OLE cohort enrolled adult and adolescent patients continuing from the Phase 3 OASIS-HAE pivotal trial, who received DAWNZERA every four (Q4W) or every eight weeks (Q8W). At Week 52 in the OLE, DAWNZERA demonstrated a 94% and 95% mean attack reduction from baseline for patients in the Q4W (n=69) and Q8W (n=14) dosing groups, respectively. Nearly all (97%) patients reported well-controlled disease as measured by the Angioedema Control Test (AECT score \u226510) at Week 52 compared to baseline.\n<\/p>\n<p>\nOASISplus also included a switch cohort evaluating DAWNZERA Q4W in patients previously treated with lanadelumab, C1-esterase inhibitor or berotralstat. At Week 52, patients who switched to DAWNZERA (n=64) experienced a 68% improvement in monthly HAE attack rate compared to baseline with prior prophylactic therapy, with 90% reporting well-controlled disease as measured by the AECT.\n<\/p>\n<p>\nIn the Phase 2 OLE study, patients treated with DAWNZERA Q4W showed a 97% mean HAE attack rate reduction over four years. The median attack-free interval was 2.7 years, and 71% of patients were attack-free for more than one year.\n<\/p>\n<p>\nAcross all studies, DAWNZERA demonstrated a favorable long-term safety and tolerability profile. The majority of treatment-emergent adverse events (TEAEs) were mild or moderate, with no serious TEAEs related to DAWNZERA.\n<\/p>\n<p>\nIonis will present a total of six posters at the congress, which are available on Ionis&#8217; <a rel=\"nofollow\" href=\"https:\/\/cts.businesswire.com\/ct\/CT?id=smartlink&amp;url=https%3A%2F%2Fir.ionis.com%2Fevents%2Fevent-details%2F2025-american-college-allergy-asthma-immunology-acaai-annual-scientific&amp;esheet=54353286&amp;newsitemid=20251105648807&amp;lan=en-US&amp;anchor=website&amp;index=3&amp;md5=9fd3ef48ff89c087760d1705dca0d10d\">website<\/a>.\n<\/p>\n<p><b>IMPORTANT SAFETY INFORMATION<\/b><\/p>\n<p><b>CONTRAINDICATIONS<br \/>\n<br \/><\/b>DAWNZERA is contraindicated in patients with a history of serious hypersensitivity reactions, including anaphylaxis, to donidalorsen or any of the excipients in DAWNZERA.\n<\/p>\n<p><b>WARNINGS AND PRECAUTIONS<\/b><\/p>\n<p><b>Hypersensitivity Reactions<br \/>\n<br \/><\/b>Hypersensitivity reactions, including anaphylaxis, have been reported in patients treated with DAWNZERA.
