Addex Pharmaceuticals ( discovers and develops 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. Our lead allosteric modulator product, ADX10059, has achieved clinical proof of concept and is in Phase IIb testing for the treatment of GERD and, separately, migraine headache. Both are important diseases for which existing products with limited efficacy have established multi-billion dollar markets despite sub-optimal efficacy. ADX10059 is a first-in-class mGluR5 inhibitor, a therapeutic strategy that also is being pursued in multiple indications by large pharma competitors.

Our products and technology already have proven their value through our partnerships with four of the top 10 pharmaceutical companies in the world. Specifically, an agreement with Ortho-McNeil-Janssen Inc. is focused on development of allosteric modulators to treat anxiety and schizophrenia. In addition, in two separate agreements with Merck & Co., Inc., we are developing allosteric modulators as drugs to treat Parkinson's disease and schizophrenia, respectively.  Finally, GlaxoSmithKline and Roche have made equity investments in Addex.
