New Drug Application and Marketing Authorization Application for neffy^® Currently Under Review with the FDA and EMA; FDA PDUFA Target Action Date Anticipated in Mid-2023

Strong Financial Position with $274.4 Million in Cash, Cash Equivalents and Short-term Investments to Support Operating Runway for the Next Three Years

SAN DIEGO, March 23, 2023 (GLOBE NEWSWIRE) -- ARS Pharmaceuticals, Inc. (Nasdaq: SPRY), a biopharmaceutical company dedicated to empowering at-risk patients and caregivers to better protect themselves from severe allergic reactions that could lead to anaphylaxis, today highlighted recent progress and reported fourth quarter and full year 2022 financial results.

“This is an incredibly exciting time for ARS, with potential regulatory approvals for neffy® around the corner and a resulting transition to a commercial-stage company. Our goal with neffy is to provide patients with the ability to deliver epinephrine with comparable pharmacokinetics to an intramuscular injection, but in an easy to use and rapidly administered needle-free nasal spray. We believe we are well on our way to achieving this goal,” said Richard Lowenthal, president and chief executive officer of ARS Pharmaceuticals. “Both our NDA and MAA for neffy are currently under review by the regulators in the U.S. and E.U. and we are on-track with our commercial preparedness activities for a potential U.S. launch later this year, if approved. We also recently reacquired European rights to neffy which enhance our optionality to evaluate potential partnerships or strategic transactions. The team has done a remarkable job executing the development of neffy, and we look forward to engaging with the regulatory agencies in an effort to impact the lives of millions of people with serious allergic reactions.”

neffy Progress

• neffy NDA and MAA for the Treatment of Allergic Reactions (Type 1), Including Anaphylaxis, Under Review with FDA and EMA: The Company’s new drug application (NDA) and marketing authorization application (MAA) for neffy for the emergency treatment of allergic reactions (Type I), including anaphylaxis in adults and children ≥30 kg (66 lbs), were accepted for review by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA), respectively. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target action date that is anticipated in mid-2023. If approved, neffy would be the first non-injectable treatment available to patients with allergic reactions (Type I), including anaphylaxis.
  
  The regulatory submissions to the FDA and EMA were based on data from four primary registrational studies showing that 2.0 mg intranasal dose of neffy met all clinical endpoints recommended by regulators and that its pharmacokinetics were within the range of approved epinephrine injection products. These data, which were presented at the 2022 American College of Allergy Asthma and Immunology Annual Scientific Meeting (ACAAI) and the 2023 American Academy of Allergy, Asthma and Immunology (AAAAI) meeting, included studies in adults, with self-administration and caregiver administration, as well as in children with Type I allergies ≥30 kg (66 lbs). In addition, neffy has been well-tolerated to date with more than 600 individuals receiving at least one dose, and many with repeat administration. Adverse events in the clinical trials were generally mild in nature without any meaningful nasal irritation or pain.

• Presented Data Supporting Use of neffy During the 2023 AAAAI Meeting: ARS presented positive data supporting neffy during the 2023 American Academy of Allergy, Asthma and Immunology (AAAAI) meeting. Presentations highlighted clinical trial data demonstrating that neffy delivered consistent epinephrine levels to attain a pharmacokinetic (PK) and pharmacodynamic (PD) profile within the range of approved intramuscular (IM) injection products with a dose proportional exposure between once and twice dosing.
  
  ARS also presented findings from surveys of 300 patients identifying that the needle is the principal reason why patients do not fill their epinephrine prescription today, and why they delay epinephrine use and use OTC products first despite treatment guidelines recommending immediate use of epinephrine.

Fourth Quarter and Full Year 2022 Financial Results

• Cash Position: Cash, cash equivalents and short-term investments were $274.4 million as of December 31, 2022. ARS believes its existing cash, cash equivalents and short-term investments will be sufficient to fund its current operating plan for at least three years.
• R&D Expenses: Research and development (R&D) expenses were $4.7 million for the quarter ended December 31, 2022, and $18.4 million for the year ended December 31, 2022.
• G&A Expenses: General and administrative (G&A) expenses were $10.7 million for the quarter ended December 31, 2022, and $18.5 million for the year ended December 31, 2022. G&A expenses for the fourth quarter increased over the prior three quarters mainly due to costs related to the merger with Silverback Therapeutics, Inc. and beginning preparations for the potential commercialization of neffy.
• Net Loss: Net loss was $14.4 million for the quarter ended December 31, 2022, and $34.7 million for the year ended December 31, 2022.

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 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 25 to 40 million people in the United States who experience Type I severe allergic reactions. Of those, only 3.3 million currently have an 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.
