was shown to be in the safe and efficacious range for children four years or older who weigh more than 15 kilograms
Findings in Chinese studies confirms U.S. data and bracketed pharmacokinetic (PK) and pharmacodynamic (PD) profiles, demonstrate comparable efficacy and safety under various conditions including self-administration, allergic rhinitis, infectious rhinitis, in allergy challenges and with repeat dosing, compared with intermuscular injection
SAN DIEGO, Feb. 18, 2025 (GLOBE NEWSWIRE) -- ARS Pharmaceuticals, Inc. (Nasdaq: SPRY), a biopharmaceutical company dedicated to empowering at-risk patients and their caregivers to better protect patients from severe allergic reactions that could lead to anaphylaxis, announced today that nine presentations will be featured at the 2025 American Academy of Allergy, Asthma and Immunology (AAAAI) Annual Scientific Meeting, February 28 to March 3, in San Diego, California. The oral presentation and posters will feature data from a wide range of studies, including pharmacokinetics and pharmacodynamics of intranasal epinephrine under normal and various conditions, physiological responses between adults and children who are administered epinephrine, and the pre-treatment journey of patients with allergic conditions. In addition to the presentations, ARS Pharma will participate in and host a variety of onsite activities during the meeting.
'We look forward to sharing additional findings from our comprehensive clinical research program with the broader allergy community at AAAAI and expect that the data will continue to build on the existing robust data on the efficacy and safety of intranasal epinephrine administration,' said Sarina Tanimoto, MD, PhD, Co-Founder and Chief Medical Officer of ARS Pharma the maker of (epinephrine nasal spray), the first and only FDA-approved needle-free treatment for Type I allergic reactions, including anaphylaxis, in adults and children who weigh ≥30 kg (66 lbs.).

About Type I Allergic Reactions Including Anaphylaxis Type I allergic reactions are serious and potentially life-threatening events that can occur within minutes of exposure to an allergen and require immediate treatment with epinephrine, the only FDA-approved medication for these reactions. While epinephrine auto-injectors have been shown to be highly effective, there are well published limitations that result in many patients and caregivers delaying or not administering treatment in an emergency situation. These limitations include fear of the needle, lack of portability, needle-related safety concerns, lack of reliability, and complexity of the devices. There are approximately 40 million people in the United States who experience Type I allergic reactions. Of this group approximately 20 million people have been diagnosed and treated for severe Type I allergic reactions that may lead to anaphylaxis, but (in 2023, for example) only 3.2 million filled their active epinephrine auto-injector prescription, and of those, only half consistently carry their prescribed auto-injector. Even if patients or caregivers carry an auto-injector, more than half either delay or do not administer the device when needed in an emergency.
About ARS Pharmaceuticals, Inc.ARS Pharmaceuticals is a biopharmaceutical company dedicated to empowering at-risk patients and their caregivers to better protect patients from allergic reactions that could lead to anaphylaxis. The company is commercializing 2 mg (trade name EUR in the EU) (previously referred to as ARS-1), an epinephrine nasal spray indicated in the U.S. for emergency treatment of Type I allergic reactions, including anaphylaxis, in adult and pediatric patients who weigh 30 kg or greater, and in the EU for emergency treatment of allergic reactions (anaphylaxis) due to insect stings or bites, foods, medicinal products, other allergens, as well as idiopathic or exercise induced anaphylaxis in adults and children who weigh 30 kg or greater.
