ARS Pharmaceuticals to Showcase Scientific Innovation and Robust Clinical Data on neffy® (epinephrine nasal spray) at 2026 American Academy of Allergy, Asthma and Immunology (AAAAI) Annual Scientific Meeting
-Five poster presentations highlight clinical advancement of neffy, real-world usability and advantages of needle-free epinephrine delivery
-Longer shelf life of nasal epinephrine compared with epinephrine auto-injectors translates into a more affordable, value-based price
-When factoring in patients’ dislike of needle-based administration, the value of a nasal option increased by more than 25%
SAN DIEGO, Feb. 10, 2026 (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 five poster presentations, one healthcare professional (HCP) case report, plus two late breakers from partners at ALK-Abelló A/S (ALK) centered on neffy, will be featured at the 2026 American Academy of Allergy, Asthma and Immunology (AAAAI) Annual Scientific Meeting, February 27 to March 2, 2026 in Philadelphia, Pennsylvania. The posters highlight health-economic analyses, patient preference research, usability and pharmacokinetic comparisons evaluating neffy relative to injectable epinephrine products.
“We are pleased to share with the broader allergy community at AAAAI a series of new clinical insights showcasing the similarity of neffy 2 mg in exposure as compared to 0.5 mg intramuscular injection, as well as positive pharmacoeconomic data that indicates neffy may be cost effective and preferred by patients over injection products,” said Sarina Tanimoto, MD, PhD, Co-Founder and Chief Medical Officer of ARS Pharma. “These studies reinforce our commitment to delivering an intuitive, affordable, and reliable nasal spray that patients and caregivers can trust in emergency situations.”
The complete list of presentations and meeting activities is below. Abstracts can be viewed at annualmeeting.aaaai.org. Attendees are encouraged to visit the ARS Pharma booth #737, view the poster presentations at the Convention Center, Level 2, Hall E, and attend a Non-CME Problem Based Learning Presentation: Reimagining Epinephrine Administration with Epinephrine Nasal Spray, to learn more about neffy.

About neffy®
neffy is a nasal spray used for emergency treatment of allergic reactions including anaphylaxis, in adults and children aged 4 years and older who weigh 33 lbs. or greater.
INDICATION AND IMPORTANT SAFETY INFORMATION FOR neffy (epinephrine nasal spray)
INDICATION
neffy is indicated for emergency treatment of type I allergic reactions, including anaphylaxis, in adult and pediatric patients aged 4 years and older who weigh 33 lbs. or greater.
IMPORTANT SAFETY INFORMATION
neffy contains epinephrine, a medicine used to treat allergic emergencies (anaphylaxis). Anaphylaxis can be life-threatening, can happen in minutes, and can be caused by stinging and biting insects, allergy injections, foods, medicines, exercise, or other unknown causes.
Always carry two neffy nasal sprays with you because you may not know when anaphylaxis may happen and because you may need a second dose of neffy if symptoms continue or come back.
Each neffy contains a single dose of epinephrine. neffy is for use in the nose only.
Use neffy right away, as soon as you notice symptoms of an allergic reaction. If symptoms continue or get worse after the first dose of neffy, a second dose is needed. If needed, administer a second dose using a new neffy in the same nostril starting 5 minutes after the first dose. Get emergency medical help for further treatment of the allergic emergency (anaphylaxis), if needed after using neffy.
Tell your healthcare provider if you have underlying structural or anatomical nasal conditions, about all the medicines you take, and about all your medical conditions, especially if you have heart problems, kidney problems, low potassium in your blood, Parkinson's disease, thyroid problems, high blood pressure, diabetes, are pregnant or plan to become pregnant, or plan to breastfeed.
Tell your healthcare provider if you take or use other nasal sprays or water pills (diuretics) or if you take medicines to treat depression, abnormal heart beats, Parkinson's disease, heart disease, thyroid disease, medicines used in labor, and medicines to treat allergies. neffy and other medications may affect each other, causing side effects. neffy may affect the way other medicines work, and other medicines may affect how neffy works.
neffy may cause serious side effects. If you have certain medical conditions or take certain medicines, your condition may get worse, or you may have more or longer lasting side effects when you use neffy.
Common side effects of neffy include: nasal discomfort, headache, throat irritation, chest and nasal congestion, feeling overly excited, nervous or anxious, nose bleed, nose pain, sneezing, runny nose, dry nose or throat, tingling sensation, including in the nose, feeling tired, dizziness, nausea, and vomiting.
Tell your healthcare provider if you have any side effects that bother you or that do not go away after using neffy.
These are not all of the possible side effects of neffy. Call your healthcare provider for medical advice about side effects. To report side effects, contact ARS Pharmaceuticals Operations, Inc. at 1-877-MY-NEFFY (877-696-3339) or the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

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, over the last three years, 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.
