Overview
Addex Therapeutics is a clinical-stage biotech focused on developing a new class of oral drugs—allosteric modulators—for neurological disorders. Its core achievement is building a robust pipeline of eight candidates, with lead programs in Phase 2/3 for Parkinson's disease dyskinesia (dipraglurant) and Phase 2 for epilepsy (ADX71149, partnered with Janssen). The company's strategy centers on advancing its proprietary GPCR modulation platform to create safer, more selective therapeutics, while pursuing strategic partnerships and funding to de-risk development and drive value.
Technology Platform
Proprietary platform for discovering oral small molecule allosteric modulators of G-protein coupled receptors (GPCRs), enabling fine-tuned modulation of neurological targets with potential for improved selectivity and safety.

Competitive Landscape
Faces competition from approved and late-stage drugs in Parkinson's dyskinesia and a crowded epilepsy market. Its differentiation lies in pioneering allosteric modulation of specific GPCR targets (mGluR, GABAB). Competes with other biotechs focused on GPCR neurology platforms, but maintains a niche expertise in glutamate and GABA receptor modulation.
