ARS Pharmaceuticals Announces neffy® (Epinephrine Nasal Spray) is available on Express Scripts Commercial National Formularies

Inclusion of neffy on Express Scripts commercial formularies was effective November 22, 2024 and expands access to patients and caregivers managing Type 1 Allergic Reactions

SAN DIEGO, Dec. 19, 2024 (GLOBE NEWSWIRE) -- ARS Pharmaceuticals, Inc. (NASDAQ:SPRY), a biopharmaceutical company dedicated to empowering at-risk patients and caregivers to better protect themselves from allergic reactions that could lead to anaphylaxis, announced today that Express Scripts, the pharmacy benefits business of Evernorth Health Services, has added neffy^® (epinephrine nasal spray) to its Commercial national formularies. This decision makes neffy broadly available to millions of their commercially insured patients across the country.

neffy 2 mg is for the treatment of Type I Allergic Reactions, including anaphylaxis, in adults and children who weigh ≥30 kg (66 lbs.). It is the first and only FDA-approved epinephrine nasal spray that provides a needle-free alternative to traditional injectable epinephrine and the first new delivery method for epinephrine in more than 35 years. Its simple and intuitive design enables rapid administration, helping patients and caregivers act quickly and confidently, and the small size is easy to carry. Additionally, neffy has a shelf-life of 30 months and temperatures exclusions up to 122 degrees Fahrenheit.

"The inclusion of neffy on Express Scripts' Commercial National Formularies significantly improves access to life-saving allergy treatment," said Sal Grausso, Head of Market Access at ARS Pharma. "This highlights the importance of providing a user-friendly solution that empowers patients and caregivers to respond quickly and effectively to severe allergic reactions, demonstrating the value of neffy in addressing unmet medical needs in the allergy community. We're also very pleased with the quick turnaround between product introduction and the inclusion of neffy on Express Scripts' formularies in only nine weeks. We will be working diligently to ensure continued access for as many patients and caregivers as possible."

This expanded access aligns with ARS Pharma's commitment to reducing barriers to care and improving outcomes for patients who rely on epinephrine during allergy emergencies. ARS Pharma anticipates other payers to join Express Scripts in providing access to neffy in the coming weeks.

To support patients in navigating coverage and affordability challenges, ARS Pharma offers a number of programs for patients and caregivers. For more information, visit www.neffy.com/savings.

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 autoinjectors 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 autoinjector prescription, and of those, only half consistently carry their prescribed autoinjector. Even if patients or caregivers carry an autoinjector, more than half either delay or do not administer the device when needed in an emergency.
