Orexo initiates new study of OX640 in participants with allergic rhinitis
The study is a cross-over study in 30 participants with allergic rhinitis and involves four treatment periods. In one of the periods, a small dose of an allergen will be sprayed into the nose of the participants to trigger an allergic reaction before being treated with OX640. This will be compared with absorption of epinephrine from OX640 without the allergen, and a commercial intramuscular epinephrine product. The fourth period will be used to document dose proportionality of OX640. In addition to the absorption of epinephrine, effects on blood pressure and heart rate will be measured as relevant parameters to understand the effect of OX640 in case of an anaphylaxis.
.
The study is expected to cost SEK 11 million . Most of these costs will be recognized in 2024 and are included in the communicated financial outlook for 2024.

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.
OX640 is an intranasal rescue medication for the treatment of severe allergic reactions (incl. anaphylaxis) with powder-based epinephrine. The product is based on Orexo´s proprietary drug delivery platform AmorphOX providing rapid and extensive systemic drug absorption after nasal administration as well as excellent physical and chemical stability. Thanks to its unique properties, OX640 has the potential to provide allergic patients with a needle-free, convenient, and rapidly acting allergy rescue product that also has long shelf-life and allows for flexible storage, both in hot and cold temperatures.
OX640-001 is a randomised sequence, single-centre, open label, 5-period crossover, phase 1 comparative bioavailability study with the primary objective to determine the relative bioavailability and absorption characteristics of four investigational formulations of OX640 versus an intramuscular auto-injector of epinephrine.
