Better understanding of allergies for better treatment

ALYATEC has created an environmental exposure chamber (EEC) in Strasbourg, offering to public researchers and pharmaceutical companies a unique research tool in the world.

This environmental exposure chamber, also called allergen challenge chamber, allows to carry out clinical studies under reproducible conditions to validate desensitization treatments and new therapeutic drugs to treat symptoms of respiratory allergies such as asthma, rhinitis and conjunctivitis.

ALYATEC’s allergen challenge chamber also helps fundamental research on respiratory allergies, which today affects nearly 30% of Europeans.

More generally, this expertise for research and clinical trials concerns all respiratory pathologies linked to the environment. It makes possible to study mechanisms of action of these diseases and to develop new therapeutics. Thereby, ALYATEC’s allergen challenge chamber contributes to the improvement of the patients’ daily life.

New Generation Environmental Exposure Chamber

New in France and unique in the world, this environmental exposure chamber located in the New Civil Hospital of Strasbourg is used under the scientific and medical supervision of Professor Frédéric de Blay, leader of Chest Disease Department.
Very innovative, ALYATEC allergen challenge chamber has been entirely designed to allow the safest and most controlled allergen provocation tests.

All parameters are controlled and secured :

  • Concentration and size of allergens tested,
  • Duration of exposure,
  • Pressure, temperature and humidity,
  • Air flow certified ISO 8,
  • Allergens used are validated by ANSM.


A unique tool in the world

ALYATEC’s allergen challenge chamber is a new generation chamber, unique in the world, which results from the meeting of Professor de Blay, a pulmonologist at the University Hospital in Strasbourg, and a leader of industry, Albert SAPORTA, former CEO of Stallergenes.

It is a pioneer environmental exposure chamber in several important aspects:

  1. The first one in which it is possible to carry out exposures with respect to all allergens.
  2. The first one having a fully controlled metrology capacity
  3. The first one located in a hospital
    • Near the Intensive Care Unit, providing absolute safety for patients
    • Near the allergy department and its team of professionals trained in the bronchial challenge for more than 30 years
  1.  The first one using allergens extracts registered in the ANSM (National Agency for the Safety of Medicines and Health Product).
