Geneva, Switzerland, 7 February 2018 – Addex Therapeutics (SIX: ADXN), a leading company pioneering allosteric modulation-based drug discovery and development, announced today the appointment of Jean-Philippe Rocher, PhD, as Co-Head of Discovery and Member of the Executive Management. Dr. Rocher is a medicinal chemistry and drug discovery expert with more than 25 years industry experience, who previously built Addex’ small molecule allosteric modulator chemistry platform. Together with Robert Lütjens, Addex’s current Head of Discovery, he will oversee the preclinical portfolio of proprietary allosteric modulator programs and lead the chemistry components of our funded research programs on GABAB PAM with Indivior PLC and TrkB PAM with the Michael J. Fox Foundation for Parkinson’s Research.


Putting back together the successful chemistry and biology partnership of Jean-Philippe Rocher and Robert Lütjens, which built the Addex allosteric modulator discovery platform and delivered our proprietary pipeline is a significant achievement,” commented Tim Dyer, CEO of Addex. “The team will initially focus on delivering on our funded research programs which are being conducted in collaboration with Indivior PLC and The Michael J. Fox Foundation for Parkinson’s Research.”

About Addex Therapeutics

Addex Therapeutics ( is a biopharmaceutical company focused on the development of novel, orally available, small molecule allosteric modulators for neurological disorders. Allosteric modulators are an emerging class of small molecule drugs which have the potential to be more specific and confer significant therapeutic advantages over conventional "orthosteric" small molecule or biological drugs. Addex's allosteric modulator drug discovery platform targets receptors and other proteins that are recognized as essential for therapeutic intervention - the Addex pipeline was generated from this pioneering allosteric modulator drug discovery platform. Addex's lead drug candidate, dipraglurant (mGluR5 negative allosteric modulator or NAM) has successfully completed a Phase 2a POC in Parkinson's disease levodopa-induced dyskinesia (PD-LID), and is being prepared to enter registration trials for PD-LID with support from the Michael J. Fox Foundation for Parkinson's Research (MJFF). In parallel, dipraglurant's therapeutic use in dystonia is being investigated with support from the Dystonia Medical Research Foundation (DMRF). Addex's second clinical program, ADX71149 (mGluR2 positive allosteric modulator or PAM) is being developed in collaboration with Janssen Pharmaceuticals, Inc for epilepsy. In addition, ADX71441 (GABAB receptor PAM) program was awarded a $5.3 million grant by the US National Institute on Drug Abuse (NIDA, a division of National Institutes of Health (NIH)) to support human studies in cocaine addiction and has been licensed to Indivior. Discovery programs include mGluR4PAM, mGluR7NAM, TrkBPAM and mGluR3NAM & PAM that are being advanced with the support of the MJFF and Swiss Commission for Innovation and Technology (CTI).
