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 reported business updates and financial results for the first quarter of 2024.

"With the completion of all requested   neffy     ^®    (epinephrine nasal spray) studies and submission of our response to FDA, we believe we are very close to delivering the first needle-free, safe, effective, and easy to carry epinephrine solution to the millions of people living with Type I allergies including anaphylaxis. Our primary focus is ensuring we are well-positioned for a successful launch of   neffy   in the U.S. upon approval, which is expected within the next six months. Importantly, we are well-capitalized with a multi-year operating runway that supports our   neffy   commercialization activities in the U.S.," said Richard Lowenthal, Co-founder, President and CEO of ARS Pharma. "Our goal is to ensure that patients around the world have access to   neffy   in a timely manner. We've completed our submission to the EMA's CHMP and expect an opinion on our MAA this quarter. We're also delighted to partner with Australian pharmaceutical leader CSL Seqirus to support the approval and commercialization of   neffy   in Australia and New Zealand. These positive updates reflect our team's strong execution and unwavering commitment to serving patients."

   U.S. Regulatory Status of neffy     for Type 1 Allergic Reactions   

• In April, ARS Pharma submitted its response to the FDA's Complete Response Letter (CRL) issued regarding its NDA for   neffy   for the treatment of Type I allergic reactions including anaphylaxis. The response addressed all additional requests in FDA's CRL, which included the positive data from a repeat dose PK/PD study of   neffy   under nasal allergen challenge conditions, and updated testing that detected no measurable nitrosamine levels, conducted per FDA's draft guidance issued in August 2023. ARS Pharma anticipates an FDA review period of up to six months, and the PDUFA date is anticipated to be October 2, 2024, based on the submission receipt date of April 2, 2024. Assuming approval on or before the anticipated PDUFA date, ARS Pharma anticipates launching   neffy   in the U.S. in the second half of 2024.
  
 

   Global Regulatory Status of neffy   

• On April 30, ARS Pharma also submitted its Day 180 response to the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) for its MAA for   neffy    . Based on the timetable included in the Day 180 comments, ARS Pharma expects CHMP to issue its opinion on the   neffy   MAA later this quarter.
 
• ARS Pharma executed an exclusive license and distribution agreement for Australia and New Zealand with CSL Seqirus, a subsidiary of CSL Limited (ASX: CSL), which is the largest Australian pharmaceutical company. Under the terms of the agreement, CSL Seqirus plans to secure regulatory approval and reimbursement and commercialize   neffy   in Australia and New Zealand. ARS Pharma will receive an upfront payment as well as potential event-related milestone payments, with a combined value of up to $5 million. Following local regulatory approval of   neffy   , ARS Pharma will be responsible for supplying finished product to CSL Seqirus at a transfer price paid to ARS Pharma.
 
• Submissions to other regulatory authorities in additional countries including China and Japan are planned for 2024.
  
 

   Clinical Expansion of neffy     for Urticaria   

• ARS Pharma is on-track to initiate an outpatient study of   neffy   for patients with urticaria, who have been previously treated with antihistamines and experience frequent acute flares. The Phase 2b trial is expected to begin dosing patients in the second half of 2024, followed by the potential initiation of a single pivotal efficacy study in 2025.
  
 

   Additional Business Highlights   

• On March 7, 2024, ARS Pharma held its first   neffy   Investor Day. ARS Pharma management was joined by two leading allergists, Dr. Jonathan Spergel, M.D., Ph.D., and Dr. Thomas B. Casale, M.D., who provided an overview of the treatment landscape for severe Type I allergies and a review of the positive clinical data submitted in the   neffy   registration package. A replay of the event can be accessed here .
 
• In March 2024, results from the upper respiratory tract infection clinical study of   neffy   were published in the Journal of Allergy and Clinical Immunology: In Practice. The results demonstrated that the pharmacokinetic and pharmacodynamics of   neffy   were not affected by upper respiratory tract infection symptoms.
 

  First Quarter 2024 Financial Results  

•   Cash Position: Cash, cash equivalents and short-term investments were $223.6 million as of March 31, 2024, which ARS Pharma believes is sufficient to fund its current operating plan for at least three years.
 
•   R&D Expenses: Research and development (R&D) expenses were $5.2 million for the quarter ended March 31, 2024, compared to $6.6 million for the quarter ended March 31, 2023. R&D expenses decreased from 2023 to 2024 primarily due to a decrease in device development costs, partially offset by an increase in clinical trial costs.
 
•   G&A Expenses: General and administrative (G&A) expenses were $8.0 million for the quarter ended March 31, 2024, compared to $12.2 million for the quarter ended March 31, 2023. G&A expenses decreased from 2023 to 2024 primarily due to a pause in pre-commercial launch activities related to   neffy   .
 
•   Net Loss: Net loss was $10.3 million for the quarter ended March 31, 2024, compared to $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 40 million people in the United States who experience Type I severe allergic reactions. Of those, only 3.2 million 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.

  About Urticaria  
Urticaria is a skin disorder that causes itchy hives and/or angioedema with an annualized incidence of 5 million in the United States, with about 40% becoming chronic urticaria; 50% of chronic urticaria cases 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 Pharma 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.

  About ARS Pharmaceuticals, Inc.

The Company is developing   neffy     ^®    (also referred to as ARS-1), an intranasal epinephrine product in clinical development for patients and their caregivers with Type I allergic reactions including food, medications and insect bites that could lead to life-threatening anaphylaxis.
