Addex's Clinical Programs and Discovery Platform Highlighted in Review of Allosteric Modulators for the Treatment of Neurodegenerative Diseases

Geneva, Switzerland, 6 February 2017 - Addex Therapeutics (ADXN.SW) announced today the publication of a review summarizing the current status of allosteric modulators (AMs) as potential novel treatments for neurodegenerative diseases, such as Parkinson`s and Alzheimer`s disease, in Current Opinion in Pharmacology (http://www.sciencedirect.com/science/article/pii/S1471489217300061). This review highlights the important contribution Addex has made in the discovery of allosteric modulator compounds.

"Allosteric modulation is a clinically proven but differentiated pharmacological approach that has significant potential to deliver novel therapeutics across a broad range of disease areas," said Robert Lütjens, Head of Discovery of Addex. "It is the combination of Addex`s proprietary biological assays and small molecule library that has enabled us to be so successful at finding drug like allosteric compounds."

In particular, the paper reviews progress made by academic and industrial laboratories to deliver allosteric modulator compounds on important drug targets, such as purinergic, muscarinic acetylcholine, and metabotropic glutamate receptors. Addex`s dipraglurant for levodopa-induced dyskinesia associated with Parkinson`s disease is highlighted as one of the most advanced clinical compounds in the field. In addition, the important potential of a number of Addex programs, such as those targeting mGlu3, 4, 5, 7 and 8 receptors in neurodegenerative disease is recognized.

The review highlights the important steps that have been made to validate these targets through the use of pharmacological tool compounds for which Addex has been an important contributor. A special emphasis has been placed on the potential to treat symptoms of diseases, such as Parkinson`s and Alzheimer`s disease, while also confirming the potential disease-modifying effects observed with AMs in preclinical studies.

Addex, with its allosteric modulation technology platform and its rich pipeline of AMs addressing all metabotropic glutamate receptor subtypes, as well as other G protein-coupled Receptors (GPCR) and non GPCR targets, is well poised to deliver novel first-in-class compounds with a potential to substantially affect neurodegenerative disease symptoms as well as disease progression. This is highlighted in the recently announced grant of $835,000 from The Michael J. Fox Foundation for Parkinson`s Research (MJFF) to advance Addex`s positive allosteric modulators (PAMs) of the tyrosine receptor kinase B (TrkB), a target for neuroprotection with potential in Parkinson`s, Alzheimer`s and Huntington`s disease.
