The company reports that it operates as a single business segment dedicated to these discovery and development efforts.
Addex Therapeutics describes itself as a clinical-stage pharmaceutical company specialized in allosteric modulation-based drug discovery and development. Allosteric modulators are small molecules that bind to specific sites on receptors or other proteins that are distinct from the primary, or orthosteric, binding site. The company highlights that this approach may offer an improved therapeutic alternative to conventional orthosteric small molecules or biological drugs.
The company states that its allosteric modulator drug discovery platform targets receptors and other proteins that are recognized as essential for therapeutic intervention. By focusing on these targets, Addex Therapeutics aims to identify and develop drug candidates that could be relevant for neurological disorders. Its disclosed collaboration activities indicate a focus on small molecule central nervous system (CNS) drug discovery programs.
Addex Therapeutics is listed on the NASDAQ Capital Market under the ticker symbol ADXN. The company also indicates that its geographical area of operations includes Switzerland and Europe. Filings with the United States Securities and Exchange Commission (SEC) identify Addex Therapeutics Ltd as a foreign private issuer with principal executive offices in Geneva, Switzerland.
Business focus and allosteric modulation
According to available information, Addex Therapeutics concentrates on an emerging class of orally available small-molecule drugs termed allosteric modulators. The company notes that allosteric modulators may offer several potential advantages over conventional non-allosteric molecules. This includes the possibility of modulating receptor activity without directly competing with endogenous ligands at the primary binding site.
The company’s allosteric modulator drug discovery platform is described as targeting receptors and other proteins considered essential for therapeutic intervention, particularly in neurological disorders. Through this platform, Addex Therapeutics pursues the discovery and development of small-molecule pharmaceutical products that fit within its allosteric modulation strategy.
Research collaborations and discovery activities
Publicly available news describes a long-standing research collaboration between Addex Therapeutics and Enamine Ltd.
