SAN DIEGO - November 13, 2024 - 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, today reported early progress on the U.S. commercial launch of neffy® (epinephrine nasal spray) 2 mg for the treatment of Type I allergic reactions, including anaphylaxis, in adults and children who weigh ≥30 kg (66 lbs.), as well as business highlights and financial results for the third quarter of 2024.

"The third quarter marked a transformative period for ARS Pharma, driven by the FDA approval of neffy in the U.S. and the European Commission approval of EURneffy® in the European Union," stated Richard Lowenthal, President and CEO of ARS Pharmaceuticals. "With strong demand among healthcare providers and patients for neffy as the first and only needle-free epinephrine treatment, robust patient support systems in place, and favorable early payer discussions ongoing, we feel very good about the early momentum in our U.S. launch. We're also proud to have further expanded the reach of neffy outside the U.S. by partnering with ALK-Abelló, a global leader in allergy product commercialization. Operationally, we stand very well positioned with a balance sheet that is further strengthened by the $145 million upfront payment from ALK, positioning us to execute our U.S. commercial plans and business goals to enable patients around the world to have access to this vital epinephrine treatment."

U.S. commercial launch ongoing for neffy, the first and only needle-free epinephrine treatment for Type 1 allergic reactions, including anaphylaxis

On August 9, 2024, the FDA approved neffy® (epinephrine nasal spray) 2 mg for the treatment of Type 1 allergic reactions, including anaphylaxis, in adults and children who weigh ≥30 kg (66 lbs.). neffy was first available for shipment on September 23, 2024, and in early October, the U.S. sales force started in the field and neffy became broadly available in retail pharmacies.

Launch to date:

In September 2024, ARS Pharma submitted a supplemental New Drug Application (sNDA) for neffy 1 mg for the treatment of Type I allergic reactions, including anaphylaxis, in adults and children who weigh 15 to 30 kg (33-66 lbs.). In November 2024, the FDA granted the sNDA priority review and assigned a Prescription Drug User Fee Act (PDUFA) target action date of March 6, 2025.

On-track with global strategy to make neffy® available worldwide

On August 22, 2024, the European Commission granted marketing authorization for EURneffy® (epinephrine nasal spray) for the emergency treatment of allergic reactions (anaphylaxis) in adults and children who weigh ≥30 kg. On November 8, 2024, ARS Pharma announced an exclusive licensing agreement with ALK-Abelló to commercialize neffy in Europe, Canada and certain other geographies outside the U.S. Under the terms of the agreement, ARS Pharma will receive an upfront payment of $145 million, and is eligible to receive up to an additional $320 million in sales, commercial and other milestones, as well as tiered double-digit royalties in the teens on net sales in the licensed territories.

The regulatory submission for approval in Australia has been filed by CSL Seqirus under its license agreement with ARS Pharma. In addition, regulatory submissions in both China and Japan are expected to be completed in November by the respective partners in those geographies. In December, ARS Pharma plans to file for regulatory submission in the United Kingdom and Canada on behalf of ALK-Abelló, and additional regulatory filings by ARS Pharma and ALK

are anticipated in 2025 to further expand global patient reach with neffy.

Clinical expansion of neffy® for urticaria to begin in 2025

ARS Pharma plans to initiate an outpatient Phase 2b study of its intranasal epinephrine technology in patients with chronic spontaneous urticaria, a prevalent skin disease, who have been treated previously with antihistamines and experience frequent acute flares. The Phase 2b trial is expected to begin in early 2025, followed by a potential single pivotal efficacy trial.

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.

About Urticaria

Urticaria is a skin disorder that causes itchy hives and/or angioedema with an annualized incidence of 5 million in the U.S. About 40% of those cases become chronic urticaria, of which 50% are non-responsive to first-line antihistamine therapy. These non-responsive patients on stable therapy regimens can experience exacerbations or flares several times a year among acute cases, and even several times a week, including up to three or four emergency room visits per year. Angioedema is also a co-occurring symptom in about 33 to 67% of these patients. There are currently no approved community use treatments for acute flares experienced by urticaria patients on chronic regimens of antihistamines. ARS Pharmaceuticals is investigating neffy for episodic symptomatic relief of these acute flares or exacerbations to improve the quality of life of urticaria patients. If neffy is approved for this indication, patients would have the option to quickly resolve exacerbations or flares at home without escalating to chronic use of systemic biologics that may have more serious side effects and benefit-risk considerations or visiting the emergency room for further treatment.
