Data on Promising Clinical-Stage Parkinson's Disease Product Addex Discovery Capabilities Illustrated

Geneva, Switzerland, 17 February 2010 - Addex Pharmaceuticals (SIX:ADXN), the allosteric modulation company, announced today that it will participate at an event hosted by The New York Academy of Sciences entitled, "Metabotropic Glutamate Receptors: Translation from Discovery to Clinical Trials." Dr. Jean-Philippe Rocher, head of core chemistry at Addex, will discuss the discovery and development of ADX48621 in a talk entitled: "Discovery of a Novel Series of Selective mGluR5 Negative Allosteric Modulators." ADX48621 has completed Phase I clinical development and is scheduled to start Phase II testing in the fourth quarter of 2010.

Metabotropic glutamate receptors were first described in 1987 and cloned in the early '90s. Today they are considered the single most promising new collection of targets for CNS drug discovery, with therapeutic potential to treat illnesses ranging from migraine to esophageal reflux, and from schizophrenia to Parkinson's disease.

The symposium, to be held at the New York Academy of Sciences conference center in New York City on February 23, 2010, from 1:00 pm - 5:00 pm, brings together national and international experts from academia and industry to present research spanning intramolecular signal transduction, regulation, pharmacology, their role in motor function, and the therapeutic use.

Addex Pharmaceuticals (www.addexpharma.com ) utilizes its unique proprietary platform technologies to discover and develop allosteric modulators for human health. Allosteric modulators are a different kind of orally available small molecule therapeutic agent, which we believe will offer a competitive advantage over classical drugs. With 15 programs in development, the Addex pipeline demonstrates the productivity and broad potential of our unparalleled platform technologies. The most advanced product, ADX48621, an mGluR5 negative allosteric modulator (NAM), has completed Phase I testing and is scheduled to start Phase II testing for Parkinson's disease levodopa associated dyskinesia (PD-LID) later this year. Our products and technology already have proven their value through our relationships with four of the top10 pharmaceutical companies in the world. Specifically, under an agreement with Ortho-McNeil-Janssen Inc., a Johnson & Johnson company, ADX71149, an mGluR2 positive allosteric modulator (PAM), is undergoing Phase I clinical testing and has potential for treatment of schizophrenia and anxiety. Under two separate agreements with Merck & Co., Inc., we are developing PAMs of mGluR4 and mGluR5 as drugs to treat Parkinson's disease and schizophrenia, respectively. In addition, SR-One, the corporate venture arm of GlaxoSmithKline, and Roche Venture Fund have made equity investments in Addex.
