OX640 is a nasal rescue medication with powder-based epinephrine for the treatment of allergic reactions (incl. anaphylaxis) and is based on the proprietary AmorphOX® technology The clinical study, OX640-002, evaluated both pharmacokinetic and pharmacodynamic effects of OX640 in subjects with and without allergic rhinitis OX640 treatments achieved clinically relevant plasma levels of epinephrine more rapidly than the intramuscular reference product Absorption from OX640 under allergic rhinitis conditions was significantly faster than under normal conditions, supporting rapid onset of effect also in patients with airway symptoms. Uppsala, Sweden – January 10, 2025 – Orexo AB (publ.), (STO:ORX) (OTCQX:ORXOY), today announces positive topline results from the clinical study OX640-002. The study evaluated the performance in subjects with and without allergic rhinitis when treated with Orexo´s nasal rescue medication including powder-based epinephrine, OX640. The study was a cross-over study in 30 subjects assessing absorption and pharmacodynamic effects of epinephrine from two doses of OX640, with one of the doses also administered during ongoing allergic rhinitis symptoms. Exposure was compared to a commercial intramuscular injection. Topline data analysis demonstrates that OX640 treatments achieved mean epinephrine plasma levels associated with clinical efficacy more rapidly than the intramuscular injection, with dose-dependent exposure levels. Absorption under allergic rhinitis conditions was significantly faster than under normal conditions, supporting rapid onset of effect also in patients with significant airway symptoms. OX640 formulations typically produced more pronounced increases in blood pressure and heart rate than the intramuscular injection, which are key effects for treatment of anaphylaxis. Systemic safety was in line with the known pharmacology of epinephrine and local effects were transient and tolerated. There were no severe or serious adverse events. Robert Rönn, SVP and Head of R&D, said: “We are pleased with the outcome of the study which further support the utility of our OX640 epinephrine nasal powder for treatment of anaphylaxis, even in case of allergic rhinitis symptoms. Importantly, the study results allow us to decide on the final commercial formulation and dose, which is critical to advance the project towards regulatory approval. The data further reinforces our view that OX640 has the potential to be a unique and differentiated needle-free epinephrine product.” For further information please contact: Nikolaj Sørensen, President and CEO Lena Wange, IR & Communications Director Robert Rönn, SVP and Head of R&D Tel: +46 (0)18 780 88 00 E-mail: ir@orexo.com About Orexo Orexo is a Swedish pharmaceutical company with 30 years of experience developing improved pharmaceuticals based on proprietary formulation technologies that meet large medical needs.

About AmorphOX® Orexo’s proprietary drug delivery platform, AmorphOX, is a powder made up of particles which are built using a unique combination of a drug, carrier materials and, optionally, other ingredients. The particles are presented as an amorphous composite of the various ingredients providing for excellent chemical and physical stability, as well as rapid dissolution. The technology works for a broad scope of active ingredients and has been validated in several human clinical studies showing rapid and extensive drug exposure. About study OX640-002 The study was a 4-period cross-over study in 30 otherwise healthy subjects with seasonal allergic rhinitis. The study was conducted off 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. The information was submitted for publication at 8.00 am CET on January 10, 2025.

CHENGDU, China I December 23, 2024 I Keymed Biosciences Inc. (HKEX: 02162) today announced the National Medical Products Administration (the “NMPA”) of China has recently approved the supplemental New Drug Application (the “sNDA”) of Stapokibart (anti-IL-4Rα monoclonal antibody, trade name: Kangyueda (康悦达), R&D codename: CM310), for the treatment of chronic rhinosinusitis with nasal polyposis. The approval is based on a multi-center, randomized, double-blind, placebo-controlled phase III clinical study to confirm the efficacy and safety of Stapokibart injection in treatment of patients with chronic rhinosinusitis with nasal polyposis. The study results showed that the data from the phase III clinical trial was positive. Compared to the placebo, Stapokibart significantly reduced nasal polyps (NPS improvement of 2.3 from baseline) and alleviated nasal congestion (NCS improvement of 0.7 from baseline) after 24 weeks. The differences were highly statistically significant (P<0.0001). Additionally, it effectively relieved rhinosinusitis, restored sense of smell, improved nasal symptoms, and enhanced quality of life. It also demonstrated a favorable safety profile. About Stapokibart Stapokibart (trade name: Kangyueda, R&D codename: CM310) is a high-efficient, humanized antibody targeting the interleukin-4 receptor alpha subunit (IL-4Rα), and is the first domestically manufactured IL-4Rα antibody drug granted marketing approval by the NMPA. By targeting IL-4Rα, Stapokibart can block both interleukin-4 (IL-4) and interleukin-13 (IL-13) signaling. IL-4 and IL-13 are two key cytokines that trigger type II inflammation. Stapokibart has demonstrated good safety and encouraging efficacy in multiple previous clinical trials, and its treatment of the indication of moderate-to-severe atopic dermatitis in adults has been approved for marketing in September 2024. As of the date of this announcement, the new drug application of Stapokibart for the treatment of seasonal allergic rhinitis has been accepted by the NMPA. SOURCE: Keymed Biosciences
