Pipeline Update

Addex announced today for the first time that its second most advanced product, ADX48621, will be developed as a potential treatment for dyskinesia associated with L-DOPA therapy in Parkinson’s disease patients. This decision was taken on the basis of available preclinical data and the company’s own undisclosed work. Addex also disclosed for the first time the targets of two early stage negative allosteric modulator (NAM) programs: a metabotropic glutamate receptor 7 (mGluR7) NAM program with potential for treatment of depression and post traumatic stress disorder (PTSD); and an mGluR2 NAM program with potential for treatment of Alzheimer’s disease and depression. Further, the Company disclosed today that it has four additional programs in the hit-to-lead stage of discovery for glaucoma, type II diabetes, obesity and migraine headaches. For competitive reasons, the G protein coupled receptor (GPCR) targeted by each of these programs is undisclosed.

About Addex 

Addex Pharmaceuticals discovers and develops allosteric modulators, an emerging class of small molecule therapeutic agents. Allosteric modulation may offer more sophisticated ways to normalize biological signaling compared to classical orthosteric agonist or antagonist drugs. Allosteric, literally translated from its Greek roots, means: other site. Thus, allosteric modulators bind receptors at sites that are distinct from the binding sites of classical small molecule orthosteric agonist and antagonist drugs.

The most advanced drug candidate, ADX10059, a negative allosteric modulator (NAM) of metabotropic glutamate receptor 5 (mGluR5), recently demonstrated clinically and statistically significant efficacy in separate Phase IIa clinical trials in gastroesophageal reflux disease (GERD) patients and migraine headache patients. 

The Addex allosteric modulation discovery and development platform has been additionally validated through collaborations with Merck & Co., Inc. and Johnson & Johnson.

Such forward-looking statements reflect the current views of Addex Pharmaceuticals Ltd regarding future events, and involve known and unknown risks, uncertainties and other factors that may cause actual results with allosteric modulators of mGluR2, mGluR4, mGluR5, mGluR7, GABAB, FSHR, GLP-1R or other therapeutic targets to be materially different from any future results, performance or achievements expressed or implied by such statements. There can be no guarantee that allosteric modulators of mGluR2, mGluR4, mGluR5, mGluR7, GABAB, FSHR, GLP-1R or other therapeutic targets will be approved for sale in any market or by any regulatory authority. Nor can there be any guarantee that allosteric modulators of mGluR2, mGluR4, mGluR5, mGluR7, GABAB, FSHR, GLP-1R or other therapeutic targets will achieve any particular levels of revenue (if any) in the future. In particular, management's expectations regarding  allosteric modulators of mGluR2, mGluR4, mGluR5, mGluR7, GABAB, FSHR, GLP-1R or other therapeutic targets could be affected by, among other things, unexpected actions by our partners, unexpected regulatory actions or delays or government regulation generally; unexpected clinical trial results, including unexpected new clinical data and unexpected additional analysis of existing clinical data; competition in general; government, industry and general public pricing pressures; the company's ability to obtain or maintain patent or other proprietary intellectual property protection. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, believed, estimated or expected.
