Our expertise

From the observation of clinical cases to the research laboratory, here is the original approach of Chrysalis-Pharma. 


Dr. Gaëtan TERRASSE has over 25 years experience in respiratory diseases and developed a new approach in consultation, to scientifically evaluate respiratory inflammation.


After an original observation of a patient, a new hypothesis has been developed for a new histamine receptor, the H4 receptor.

The hypothesis tested in the research laboratory of the Necker Hospital (CNRS team of Michel DY) laid the foundation for a pharmacological explanation based on the initial clinical observation.
