Nasal Congestion and Exposure of Epinephrine Intranasally

The Effect of Nasal Congestion on the Bioavailability of Intranasally Administered Epinephrine in Healthy Adult Subjects with Seasonal Allergies
The Effect of Nasal Congestion on the Bioavailability of Intranasally Administered Epinephrine in Healthy Adult Subjects with Seasonal Allergies
Bryn Pharma presented their findings from a 5 Period, 5-way crossover study during a virtual meeting at the American Academy of Allergy, Asthma & Immunology.
Results suggested that the bi-dose nasal spray may produce a more favorable epinephrine exposure profile and alleviation of anaphylactic symptoms as compared with the autoinjector.
At the 2019 American College of Allergy, Asthma & Immunology National Conference (ACAAI) in Houston, Bryn Pharma presented findings from their preclinical study assessing intranasal epinephrine effects on pharmacokinetics and heart rate in a nasal congestion canine model. The full manuscript of the study was released in Respiratory Research on April 3, 2020.
In the study, intranasal epinephrine entered the blood plasma even in the presence of nasal congestion.
Bryn Pharma recently released more clinical data in Pharmacology Research & Perspectives. The study examined pharmacokinetic and heart rate effects of Bryn Pharma's intranasal (IN) epinephrine versus intramuscular (IM) injection. This comparative study was performed in a canine model.
Results from the study were released on April 17, 2020. Overall, IN epinephrine demonstrated advantages over IM epinephrine, including rapid increase in plasma epinephrine and lack of increased heart rate over time.

The Bryn Pharma team recently released an open-label, 2-part comparative bioavailability study to compare pharmacokinetic and pharmacodynamics after epinephrine intranasal (IN) or intramuscular (IM).
Results included comparative measures. Two epinephrine doses in the same nostril led to increased epinephrine absorption versus 2 IN doses in opposite nostrils and 2 IM doses;2 epinephrine doses in the same or opposite nostrils led to substantially greater epinephrine absorption vs 1 epinephrine IM dose. Epinephrine IN was also found to be safe and well-tolerated.
In November 2019, Bryn Pharma released the results of a multicenter, randomized crossover healthcare professional preference study between the EpiPen® auto-injector and the bi-dose intranasal epinephrine spray. These results were presented at the American College of Allergy, Asthma & Immunology National Conference (ACAAI), taking place November 7–11, in Houston, TX.
Results from the study show significant preference in 56 healthcare professionals for the bi-dose epinephrine nasal spray over the EpiPen® auto-injector based on an array of assessments.
In October 2019, Bryn Pharma released the results of a multicenter, randomized crossover patient preference study between the EpiPen® auto-injector and the bi-dose epinephrine nasal spray were presented at the American Academy of Pediatrics (AAP) National Conference in New Orleans, LA.
Results from the study show patients’ significant preference for the bi-dose epinephrine nasal spray over the EpiPen® auto-injector on various metrics including comfort, ease of use, portability, and overall preference. The study assessed other preference factors as well.
We are developing an affordable, needle-free, small, and easy to use epinephrine nasal spray for the treatment of anaphylaxis. Studies have shown that, despite practice and prescription guidelines, most people at risk for anaphylaxis don't always carry one of their autoinjectors, and even fewer carry two epinephrine autoinjectors. This is due in part to size and cost of the products, putting patients at greater risk of severe complications during an allergic reaction. UTULY™ is designed to provide patients with a life-saving treatment that is affordable, needle free, small, easy to use and complies with practice parameters.
UTULY™ is not currently approved by the FDA or any international regulatory authority.
UTULY™, the brand name, is conditionally approved by the FDA.
