Guillaume DuveyGuillaume Duvey, PhD

CSO, co-founder

Dr Duvey has spent 15 years in the pharmaceutical and biotechnology industry, focusing on drug discovery and development for critical diseases in the neuroscience field. After a PhD in medicinal chemistry awarded in 2000 from University of Rouen (France), Dr. Duvey joined the R&D division of Janssen in France to advance several research programs in the various fields of oncology, virology and CNS disorders. In 2004, he joined the Swiss biotechnology start-up Addex therapeutics where he led several preclinical programs, developing in particular novel allosteric modulators for glutamate receptors (mGlu2, mGlu5 and mGlu7) for various indications. These discoveries led to numerous small molecule clinical candidate nominations for therapeutic indications like Parkinson’s disease, anxiety, pain, gastroesophageal reflux disease and mood disorders. Dr. Duvey notably led the research collaboration with Janssen Pharaceuticals in Belgium and Spain (J&J group), to develop novel mGlu2 allosteric modulators for the treatment of schizophrenia and anxious depression. This collaboration successfully allowed the identification of the clinical candidate ADX71149/JNJ40411813 currently in Phase 2 clinical development. In 2010, he held senior scientific management position, and as Group Leader was responsible for the medicinal chemistry of the metabolic disorder and inflammation business units, driving a team of 11 scientists. He is co-author of more than 25 patents and peer-reviewed articles, as well as a book chapter dedicated to drugs acting on mGlu2 and mGlu5.

In addition to his scientific accomplishments, Dr. Duvey served as Research Director from 2012, where he was responsible for developing strategical scientific partnerships and technological platform integrating modern techniques for identification, characterization and optimization of preclinical molecules for novel targets and new indications.

As CSO, Dr. Duvey will oversee the scientific operations of the company and will drive forward PRAGMA’s program, both in house and through partners,  into clinical Proof-of-Concept studies.
