Sometimes an idea emerges in the medical field that is so simple, yet so effective, that it has the potential to revolutionize how we treat a certain condition. DBV-Technologies may well have come up with just such an idea in the shape of its Viaskin patch.
The Viaskin® patch is composed of an adhesive patch and a compound-holding chamber. This contains carefully-calibrated amounts of an immunoactive compound or antigen in powder form. Anything from a couple of micrograms of this substance to a few hundred may be kept in the chamber, from where it is slowly released into the skin. The gradual release of the compound allows the body to slowly develop a certain level of tolerance for the antigen in question, which would previously have provoked an allergic reaction in the patient.
The basic principle of the patch can be applied to many different allergies. It is also suitable for use as an allergy diagnosis tool, with the first example of such a patch being the Diallertest® Milk cow’s milk allergy test for children. http://www.dbv-technologies.com/en/products/ contains more information on the different allergies that are being targeted by this technology. Peanut, cow’s milk protein and house dust mite allergies are all in DBV-Technologies’ sights!
