ARS Pharmaceuticals Announces Presentation of Clinical Data Supporting neffy® (epinephrine nasal spray) for the Treatment of Allergic Reactions (Type I) including Anaphylaxis
Data from Pivotal Clinical Trials to be Presented in Five Poster Presentations at the 2022 American College of Allergy, Asthma and Immunology Annual Scientific Meeting
Data Support New Drug Application for neffy®, Currently Under Review with U.S. FDA
SAN DIEGO, Nov. 10, 2022 (GLOBE NEWSWIRE) -- ARS Pharmaceuticals, Inc. (NASDAQ: SPRY) (ARS or the Company), 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 announced that positive clinical data supporting neffy® (previously referred to as ARS-1), the potential first non-injectable medicine for treatment of allergic reactions (Type I), including anaphylaxis, will be presented during the 2022 American College of Allergy Asthma and Immunology Annual Scientific Meeting (ACAAI). The meeting is being held November 10-14, 2022, in Louisville, Kentucky.
Presentations will highlight findings from multiple clinical trials of neffy (EPI-15 and EPI-16) that were included in the company’s New Drug Application (NDA) for neffy as an emergency treatment of allergic reactions (Type I) including anaphylaxis in adults and children ?30 kg (66 lbs). The U.S. Food and Drug Administration (FDA) has accepted the NDA for neffy for review with a Prescription Drug User Fee Act (PDUFA) target action date anticipated in mid-2023.
Data from the EPI-15 and EPI-16 clinical trials demonstrated that neffy delivered consistent epinephrine levels to attain pharmacokinetic (PK) profile in range of approved intra-muscular (IM) injection products’ PK under normal and rhinitis conditions. Additionally, neffy’s Pharmacodynamic (PD) profile, the surrogate measure for assessing clinical effectiveness in anaphylaxis (for example, increased blood pressure, heart rate), demonstrated comparable or greater PD response compared with currently approved IM injectable products. These data also provide important insights into the mechanism of action of intranasal epinephrine. ARS will also present findings from a physician/caregiver survey, which suggests that patients and caregivers have a preference for a needle-free epinephrine alternative and would dose neffy sooner in the course of an allergic reaction without the hesitation caused by fear of the needle and pain.
“We are pleased to share these data from two of our primary clinical trials for neffy, both of which provide critical insights into neffy’s potential as the first intranasal medicine for treating severe allergic reactions,” said Richard Lowenthal, M.Sc., MSEL, co-founder and chief executive officer of ARS. “Severe allergic reactions can be life-threatening, and today’s standard of care is needle-bearing injectable devices associated with numerous administration challenges. The totality of the data generated supports that neffy achieves a PK/PD profile comparable to injectable products, while potentially offering patients a safe, effective and easy to administer, no-needle, no-wait option to approved epinephrine injection devices. With our NDA currently under review by FDA, we are committed to partnering with the Agency and Advocacy groups to ensure we can bring neffy to patients with Type I allergic reactions and their caregivers.”
Details of the presentations are as follows:
Title: Pharmacokinetics/Pharmacodynamics After Single and Repeat Administration of ARS-1,
Epinephrine Auto-Injector, and Manual Intramuscular Injection (EPI-15)
Date & Time: Friday, Nov 11 at 5:30 PM ET
Session: Other anaphylaxis
Data Summary: Pharmacokinetic profile following neffy 2.0 mg is within the range of currently approved injection products. neffy’s pharmacodynamic profile is comparable to or better than EpiPen or manual injection, suggesting that neffy may be at least as efficacious as these approved products.
Title: Pharmacokinetics and Pharmacodynamics of ARS-1 and Manual Intramuscular Injection
in Subjects With/Without Allergic Rhinitis (EPI-16)
Date & Time: Friday, Nov 11 at 5:00 PM ET
Session: Other anaphylaxis
Data Summary: Epinephrine absorption via neffy 2.0 mg under rhinitis resulted in more rapid absorption due to nasal symptoms including mucosal oedema. neffy’s pharmacodynamic profile under rhinitis is comparable to manual injection, suggesting that neffy may be at least as efficacious as this approved product.
Title: Epinephrine Nasal Spray (ARS-1) and Intramuscular Injection:
Pharmacokinetic/Pharmacodynamic Differences and Differential Affinities for Adrenergic
Date & Time: Friday, Nov 11 at 5:15 PM ET
Session : Other anaphylaxis
Data Summary: neffy 1.0 mg increases systolic blood pressure and heart rate more efficiently than injections, eliciting a comparable pharmacodynamic response at a lower epinephrine concentration that may be attributed to its bypassing of the beta 2-receptors into skeletal muscle in the thigh.
Title: Time Before Use of Epinephrine Injectable Devices and Triggers Driving Use: A
Date & Time: Friday, Nov 11 at 4:15 PM ET
Session : Adverse Drug Reactions, Insect Reactions, Anaphylaxis
Data Summary: The reasons for the delay in use of an epinephrine injectable device had a significant relationship with needle, requirement to go to ER, uncertainty about the symptom being warranted for injection, potential side effects, fear to use, pain, and size of device.
The results suggest that a device that addresses the reasons for delay and hesitation may help patients and caregivers to use the device without hesitation.
Title: Epinephrine Via Needle-Free Device Would Be Administered Faster After Symptoms: Results of a Patient/Caregiver Survey
Date & Time: Friday, Nov 11 at 4:45 PM ET
Session: Adverse Drug Reactions, Insect Reactions, Anaphylaxis
Data Summary: A needle-free option for administering epinephrine would be used sooner after symptoms developed and is perceived as being easier to use versus an injectable device. This underscores the need to develop epinephrine modalities utilizing a non-needle-based delivery system.
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.
