SPRY ARS Pharmaceuticals Inc

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.

About neffy®

neffy is an intranasal epinephrine product for patients with Type I allergic reactions including food, medications, and insect bites that could lead to life-threatening anaphylaxis.

INDICATION AND IMPORTANT SAFETY INFORMATION FOR neffy (epinephrine nasal spray)

INDICATION

neffy 2 mg is indicated for emergency treatment of Type I allergic reactions, including anaphylaxis, in adult and pediatric patients who weigh 30 kg or greater.

IMPORTANT SAFETY INFORMATION

It is recommended that patients are prescribed and have immediate access to two neffy nasal sprays at all times. In the absence of clinical improvement or if symptoms worsen after initial treatment, administer a second dose of neffy in the same nostril with a new nasal spray starting 5 minutes after the first dose.

neffy is for use in the nose only.

Advise patients when to seek emergency medical assistance for close monitoring of the anaphylactic episode and in the event further treatment is required.

Absorption of neffy may be affected by underlying structural or anatomical nasal conditions.

Administer with caution to patients who have heart disease; epinephrine may aggravate angina pectoris or produce ventricular arrhythmias. Arrhythmias, including fatal ventricular fibrillation, have been reported, particularly in patients with underlying cardiac disease or taking cardiac glycosides, diuretics, or anti-arrhythmics.

The presence of a sulfite in neffy should not deter use.

neffy may alter nasal mucosa for up to 2 weeks after administration and increase systemic absorption of nasal products, including neffy.

Patients with certain medical conditions or who take certain medications for allergies, depression, thyroid disorders, diabetes, and hypertension, may be at greater risk for adverse reactions.

Epinephrine can temporarily exacerbate the underlying condition or increase symptoms in patients with the following: hyperthyroidism, Parkinson’s disease, diabetes, renal impairment. Epinephrine should be administered with caution in patients with these conditions, including elderly patients and pregnant women.

Adverse reactions to neffy may include throat irritation, intranasal paresthesia, headache, nasal discomfort, feeling jittery, paresthesia, fatigue, tremor, rhinorrhea, nasal pruritus, sneezing, abdominal pain, gingival pain, hypoesthesia oral, nasal congestion, dizziness, nausea, and vomiting.

These are not all of the possible side effects of neffy. To report suspected adverse reactions, contact ARS Pharmaceuticals Operations, Inc. at 1-877-MY-NEFFY (877-696-3339) or 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 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.
