ARS Pharmaceuticals Highlights Progress and Reports First Quarter 2023 Financial Results

FDA Advisory Committee Votes in Support of Favorable Benefit-Risk Profile for neffy® for the Treatment of Allergic Reactions (Type I), Including Anaphylaxis

New Drug and Marketing Authorization Applications for neffy Under Review with FDA and EMA, Respectively; FDA PDUFA Target Action Date Anticipated mid-2023

$264.5 Million in Cash, Cash Equivalents and Short-term Investments to Support Operating Runway for the Next Three Years, Including the Planned Commercialization of neffy in the United States

SAN DIEGO, May 15, 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 first quarter 2023 financial results.

“For the millions of people living with Type I allergic reactions including anaphylaxis, we believe that neffy (nasal epinephrine spray), a small, needle-free and easy-to-use nasal spray, could provide a much-needed alternative to the currently approved epinephrine injection devices. Despite their effectiveness, these devices are limited in usage because many patients and caregivers do not carry, avoid using or hesitate to use them,” said Richard Lowenthal, president and chief executive officer of ARS Pharmaceuticals. “Throughout the first quarter, we’ve made important strides toward bringing neffy to patients. We are glad to have had the opportunity to discuss neffy with the FDA’s Advisory Committee during our recent meeting and are incredibly pleased with the outcome and the committee’s support of neffy for adults and children.”

Eric Karas, chief commercial officer added, “As we look ahead, with both our NDA and MAA for neffy currently under review by the regulators in the U.S. and EU, we are laser focused on our commercial preparedness activities. Over the last several months, we’ve made significant progress in our Commercial Launch Readiness. We are preparing to launch a 125-person salesforce focusing on specialists and healthcare providers who prescribe epinephrine and will have an array of patient and provider services established to ensure affordability. Access to neffy is a key focus and priority for us, and we have started to work with drug benefit plans to educate and raise awareness about new routes of administration that will help ensure the prompt use of epinephrine for severe allergic reactions, including anaphylaxis.”

neffy® Progress

• FDA Advisory Committee Supports neffy Potential for the Treatment of Allergic Reactions (Type I), Including Anaphylaxis, Under Review with FDA and EMA: The U.S. Food and Drug Administration’s (FDA) held a Division of Pulmonary-Allergy Drug Advisory Committee (PADAC) meeting on May 11, 2023, to review the New Drug Application (NDA) for neffy. The committee voted 16:6 in favor for adults, and 17:5 in favor for children (<18 years of age and ≥30 kg), that available data support a favorable benefit-risk assessment for neffy in the treatment of severe allergic reaction (Type I), including anaphylaxis, for adults and children who weigh more than 30kg. The PADAC decision was based on a review of comprehensive data from clinical studies developed in agreement with the FDA, which support a positive risk-benefit profile for intranasal (IN) epinephrine safety and effectiveness, compared to epinephrine injection. We believe the studies demonstrated and the majority of the Committee’s discussion supported that neffy shows:
  • Comparable or greater pharmacodynamic (PD) response (systolic blood pressure and heart rate) vs. intramuscular injection that is observed even at 1 minute after dosing of neffy. Increases in systolic blood pressure and heart rate are the outcomes monitored by physicians to assess clinical response, and therefore ARS considered PD response to be a surrogate for efficacy. The majority conclusion of the Committee also suggests that PD was more important and informative given the high PK variability of injection products.
  • Comparable or greater pharmacokinetic (PK) data (epinephrine levels in the blood) vs. intramuscular injection at all time points based on integrated data across the three primary clinical studies. This includes a “real-world” self-administration study in allergic reaction (Type I) patients, where PK was statistically greater than intramuscular injection during the early timepoints when clinical response is observed. Importantly, exposures with neffy in all clinical studies were less than the upper limit represented by EpiPen to ensure safety.
  • Effective IN delivery of systemic epinephrine and PD response even with nasal congestion or runny nose (e.g., during allergic rhinitis or upper respiratory tract infection)
  • Comparable safety to injection that is generally mild in nature without any meaningful nasal irritation or pain, without needle-related risks
• FDA PDUFA Target Action Date Anticipated Mid-2023: 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), are under review by the FDA and the European Medicines Agency (EMA), respectively. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target action date anticipated mid-2023. If approved, neffy would be the first non-injectable treatment available to patients with allergic reactions (Type I) including anaphylaxis.

First Quarter 2023 Financial Results

• Cash Position: Cash, cash equivalents and short-term investments were $264.5 million as of March 31, 2023, which ARS believes are sufficient to fund its current operating plan for at least three years.
• R&D Expenses: Research and development (R&D) expenses were $6.6 million for the quarter ended March 31, 2023.
• G&A Expenses: General and administrative (G&A) expenses were $12.2 million for the quarter ended March 31, 2023.
• Net Loss: Net loss was $15.0 million for the quarter ended March 31, 2023.

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.
