Licensing partners in key Asia Pacific countries have filed for approval of neffy (epinephrine nasal spray) 2 mg with regulatory agencies

SAN DIEGO, Dec. 12, 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 its licensing partners in China, Japan and Australia have filed for approval of neffy® (epinephrine nasal spray) 2 mg in their respective countries. neffy 2 mg was recently approved in the U.S. for the treatment of Type I Allergic Reactions, including anaphylaxis, in adults and children who weigh ≥30 kg (66 lbs).

“Given the life-saving potential of neffy for the emergency treatment of severe allergic reactions, our focus is on making it available as quickly and as broadly as possible worldwide,” says Richard Lowenthal, Co-Founder, President and CEO of ARS Pharmaceuticals. “People in the Asia Pacific region could soon be saying hello to neffy where the unique attributes of the product, such as being needle-free, easy to dispose, a smaller size with temperature excursions up to 122°F (50°C), and a 30 month shelf life are particularly important. We are thankful to our licensing partners in these countries for filing with their respective regulatory agencies.”

Among the numerous clinical trials conducted by ARS Pharma and our licensing partners in support of filings in Japan and China, the Company also conducted a Phase 3 study in Japanese pediatric patients aged 6-17 (n=15) who developed anaphylactic symptoms after an oral food challenge (OFC). neffy was dosed when patients demonstrated respiratory, gastrointestinal, or circulatory symptoms that were grade 2 or higher, per the Severity Classification of Organ Symptoms by the Japanese Society of Allergology Anaphylaxis Guidelines 2022. The results of this study found that 100% of the patients who developed symptoms responded to a single dose of neffy. The median time to complete resolution of anaphylaxis symptoms was 16 minutes.

Pediatrix, the ARS partner in China, also conducted an 81 person PK/PD study in Chinese persons that replicated the U.S. primary studies conducted by the Company with single and repeat dose by caregivers, self-administration and nasal allergen challenge. The results obtained from these PK/PD studies in China gave very similar results to those obtained in the U.S. clinical trials with neffy.

ARS Pharma retains all U.S. rights for neffy and has existing licensing partnerships in China, Japan, Australia and New Zealand with Pediatrix Therapeutics, Alfresa Pharma, and CSL Seqirus, respectively. ARS Pharma also has an exclusive agreement with ALK-Abelló to commercialize neffy in Europe (marketed as EURneffy in the European Union and obtained EU approval in August, 2024), Canada and other geographies outside the United States.
