People who don’t suffer from allergies sometimes wonder what all the fuss is about. However, the hundreds of millions across the globe who do will be following DBV-Technologies’ (http://www.dbv-technologies.com/en/) efforts to combat this curse with great interest.

The technology behind the Viaskin® patch

Numerous techniques to treat or at least alleviate the symptoms of allergic reactions have been tried in the past. These methods have often been very hit and miss. DBV-Technologies uses a different approach, called epicutaneous immunotherapy. Epicutaneous immunotherapy, as its name suggests, works by administering allergens directly to the patient’s skin. Also known as EPIT, this method takes the form of a patch that can be worn by children and adults of all ages. This Viaskin® patch contains layers of protein (i.e. allergens). These are sprayed evenly across the surface of the patch by means of special electrospray technology (see the image below). This technique aims to ‘desensitize’ allergy sufferers over time to their particular allergy. DBV-Technologies are currently working on patches for peanut, cows’ milk protein and house dust mite allergies, which are amongst the most common allergies.
