Sometimes old problems need a radically new solution. If you take a look at http://www.dbv-technologies.com/en/ you’ll see that this is very much the case with the issue of food allergies. These allergies affect hundreds of millions of people all over the world and are especially common in western countries. The foods in question range from white fish, shellfish and egg to peanuts and cow’s milk.
DBV-Technologies has rejected the injections and drops that have characterized the pharmaceutical industry’s approach to immunotherapy up to now. Instead, it has come up with an epicutaneous patch, which as its name suggests, works through contact with the patient’s skin. The diagram and photograph below will give you an idea of how it functions. Its main characteristics include a titanium backing, to which electrically-charged protein particles (antigens) are applied by an electrospray; a condensation chamber, to hydrate the skin, and an adhesive crown to anchor the patch firmly to the skin. The patch is essentially designed to safely deliver antigens to the patient’s body and thus begin the allergy ‘desensitization’ process. It exists in house dust mite, cow’s milk protein and peanut forms.
