ARS Pharmaceuticals Announces EURneffy (adrenaline nasal spray) Recommended for Approval by CHMP for Emergency Treatment of Allergic Reactions (anaphylaxis)


EURneffy positioned to be the first and only needle-free adrenaline option authorized for emergency treatment of allergic reactions (anaphylaxis) in Europe

Positive CHMP opinion and recommendation for approval of a mixed application for marketing authorization based on comprehensive data package comparing EURneffy to approved injectable products across a range of dosing scenarios as well as supportive historical data from injectable products

Same data package under review by FDA with a PDUFA date of October 2, 2024


SAN DIEGO, June 28, 2024 (GLOBE NEWSWIRE) — ARS Pharmaceuticals, Inc. (Nasdaq: SPRY), a biopharmaceutical company dedicated to the development of products to better protect patients from severe allergic reactions that could lead to anaphylaxis, announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion on the application for marketing authorization for EURneffy® (adrenaline nasal spray) and recommended related market authorization in the European Union (EU) for the emergency treatment of allergic reactions (anaphylaxis). The CHMP positive opinion will now be submitted to the European Commission (EC) for the formal marketing authorization process, which is expected to occur in Q3 2024.

“Today’s announcement marks a major milestone in the treatment of severe allergies and moves us one step closer to bringing EURneffy to patients in the EU as the first and only needle-free adrenaline option for the emergency treatment of allergic reactions, up to anaphylaxis,” said Richard Lowenthal, Co-Founder, President and CEO of ARS Pharma. “EURneffy’s needle-free, smaller form and longer and less temperature-sensitive shelf-life may increase the likelihood that patients will both carry and administer adrenaline, which improves outcome of allergic reactions.”

The positive opinion and recommendation for approval of a mixed application for marketing authorization grounded on Article 8(3) of Directive 2001/83./EC from the CHMP is based on data from one of the most extensive nasal spray development programs in history involving more than 700 study participants and over 1,200 administrations, as well as studies and peer-reviewed literature substituting or supporting certain tests and studies. The basis of approval for EURneffy in Europe was efficacy supported by surrogate pharmacodynamic endpoints. The pharmacodynamics and pharmacokinetics of 2 mg EURneffy were evaluated across a range of dosing conditions, including single and repeat dosing, self-administration by patients, dosing in pediatrics, and during multiple nasal conditions that can cause congestion and rhinorrhea such as nasal allergen challenge or infectious rhinitis caused by a cold/flu. The EURneffy mixed application under Article 8(3) of Directive 2001/83./EC will benefit from an eight-year period of data protection whereby another applicant cannot rely on support from the EURneffy application, and a ten-year period of marketing protection during which a generic, hybrid or biosimilar cannot be placed on the market. The issued composition of matter and method of treatment patents covering EURneffy in Europe have an expiration date in 2039.

Following grant of marketing authorization by the EC expected in Q3 2024, ARS Pharma anticipates that EURneffy will be made available to patients in Europe in Q4 2024 by a pharmaceutical company with an already established commercial footprint in Europe.

The same data package reviewed by CHMP that resulted in its positive opinion and approval recommendation was submitted to the U.S. Food and Drug Administration (FDA) on April 2, 2024. FDA acknowledged receipt of the submission and considered it a complete response to the September 19, 2023 action letter with no comments. The company’s New Drug Application is under review by FDA, with a neffy® PDUFA action date assigned by the FDA of October 2, 2024.

EURneffy is the trade name for neffy® (epinephrine nasal spray) in the European Union.

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 approved medication for these reactions in Europe. While adrenaline 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. Even if patients or caregivers carry an autoinjector, more than half either delay or do not administer the device when needed in an emergency.

The Company is developing neffy® (trade name EURneffy in the EU) (previously 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.
