ARS Pharmaceuticals Submits sNDA to FDA for neffy® 1 mg Dose for Pediatric Patients with Type I Allergic Reactions Who Weigh 15 to 30 kg (33-66 lbs.)

If approved, neffy 1 mg will be the first and only needle-free epinephrine treatment available for younger school-aged children

The submission of neffy 1 mg sNDA follows FDA approval on August 9, 2024, of neffy (2 mg) for the treatment of Type I Allergic Reactions, including anaphylaxis, in adults and children who weigh 30 kg (66 lbs.) or greater

SAN DIEGO, Sept. 09, 2024 (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 the submission of a supplemental New Drug Application (sNDA) for neffy^® 1 mg for the treatment of Type I Allergic Reactions, including anaphylaxis, in children who weigh 15 to 30 kg (33-66 lbs.). Pharmacokinetic (PK) data for neffy 1mg were slightly higher than that of adults who receive the same dose and pharmacodynamic (PD) response was similar.

Food allergies affect approximately six million children in the U.S., of which more than 40 percent have experienced a severe allergic reaction such as anaphylaxis. Additionally, studies show that two out of three children are afraid of needles and more than half of parents express fear about using their child's epinephrine auto-injector – a potentially lifesaving treatment.

"Fear of needles is a common reason children refuse treatment with auto-injectors. If approved, neffy 1mg will be the first needle-free epinephrine option for younger children, in addition to being the first new delivery method for this population in more than 35 years," says Richard Lowenthal, Co-Founder, President and CEO of ARS Pharmaceuticals. "Nearly half of all current epinephrine auto-injector prescriptions are for children, and more than half of those are for children weighing 15 to 30 kg (33-66 lbs.). We believe there is a clear need for innovative treatments like neffy 1mg."

Highlights from the data submitted to the FDA underscore several key attributes:

• No risk of needle-related adverse events including accidental injection into the hand or fingers of a child or caregiver. This occurs approximately 3,500 times each year in the U.S. with epinephrine injection devices and disproportionately affects 15 to 30 kg (33-66 lb.) pediatric patients.
• Simple insert and press mechanism delivers epinephrine almost instantly without any hold time required in the nose.
• Human factor studies showed that adults without knowledge of the disease or device (e.g. a babysitter or a teacher), were able to successfully use the device by simply reading the instructions. These studies also showed that untrained children as young as 10 years of age can easily use neffy with self-administration.
• neffy allows for temperature exposure up to 122°F (50°C). If accidentally frozen, it can be thawed and administered.

"There is no doubt that this innovation is going to save lives. Patients need options, and neffy is helping to solve that issue," said Eleanor Garrow-Holding, President and CEO of the Food Allergy & Anaphylaxis Connection Team (FAACT), a national patient advocacy group raising awareness for all individuals affected by food allergies and life-threatening anaphylaxis. "There has been little advancement in emergency treatments for this community, especially to address concerns about children carrying and using an epinephrine auto-injector. For the safety of our children with food allergies, making neffy 1mg available as soon as possible must be a high priority."

About Type I Allergic Reactions including Anaphylaxis

Type I severe 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 severe allergic reactions due to food, venom or insect stings. Of those, only 3.3 million currently have an 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.
