UPPSALA, Sweden, June 2, 2025 /PRNewswire/ -- Orexo AB (publ.), (STO: ORX) (OTCQX: ORXOY), announces the company will attend the 2025 EAACI Congress in Glasgow, UK, on June 13-16. The European Academy of Allergy and Clinical Immunology (EAACI) is a leading global association for the treatment of allergic and immunology diseases, including members representing over 16,000 clinicians, researchers, and health professionals from 125 countries.
On June 15, Dr. Anne K. Ellis, Professor and Chair of the Division of Allergy & Immunology at Queen's University (Kingston, Ontario, Canada) and advisor to Orexo will present on behalf of the company. Dr. Anne K. Ellis will present data from the OX640-002 clinical study, which, among other findings, demonstrated that epinephrine was absorbed significantly faster under allergic rhinitis conditions compared to normal conditions. These results support a rapid onset of action, even in patients experiencing airway symptoms.
In addition to the oral presentation, Orexo's SVP and Head of R&D, Robert Rönn, will present a scientific poster demonstrating detailed stability data for OX640.
"We look forward to attending this important congress. Thanks to our powder-based drug-delivery technology, AmorphOX®, we are able to present strong data from the second clinical study of OX640, along with a leading stability profile. I am confident that OX640 has the potential to become a convenient, effective, and reliable rescue medication for people at risk of severe allergic reactions," said Robert Rönn, SVP and Head of R&D.

About the OX640-002 study
The study was a 4-period cross-over study in 30 otherwise healthy subjects with seasonal allergic rhinitis. The study was conducted during allergy season with no ongoing allergy symptoms in subjects. Epinephrine plasma levels, blood pressure and heart rate were collected after administration of two different doses of OX640 and 0.3 mg intramuscular epinephrine. In one treatment period, one of the OX640 doses was administered following nasal administration of allergens, producing acute allergic rhinitis symptoms in the subjects.
