Addex Therapeutics Publishes Preclinical Research Demonstrating Therapeutic Potential Of ADX71743 In Regulating Sleep And Wakefulness Addex Therapeutics announced publication of new preclinical research demonstrating that ADX71743, a selective negative allosteric modulator (NAM) of metabotropic glutamate receptor 7 (mGlu7), significantly modulates sleep-wake regulation and stress-related neurochemistry in animal models. The data, published in the International Journal of Neuropsychopharmacology, expands the growing body of evidence supporting mGlu7 as an important mechanism regulating key brain functions and a promising therapeutic target across a range of central nervous system disorders, including mood disorders, anxiety disorders, post-traumatic stress disorder (PTSD), and other conditions associated with dysregulated stress responses. In the study, ADX71743 increased wakefulness while reducing both REM and non-REM sleep in rats. The compound also altered stress-induced changes in key neurotransmitters, including glutamate, GABA and monoamines, across multiple brain regions in awake animals, producing neurochemical effects consistent with modulation of stress-responsive neural circuits. Together, these findings further validate the pharmacological profile of selective mGlu7 inhibition in vivo and provide additional support for the therapeutic potential of this novel mechanism. Previous studies have demonstrated that selective mGlu7 inhibition can modulate anxiety-related behaviours, disrupt maladaptive fear memory reconsolidation and influence glutamatergic signalling in both rodent and human brain tissue. ADX71743 is a potent, selective, brain-penetrant negative allosteric modulator of metabotropic glutamate receptor 7 (mGlu7). The compound has served as the prototype molecule underpinning numerous publications investigating the therapeutic potential of mGlu7 modulation across anxiety, stress-related disorders, sleep regulation, fear memory and visceral pain. ADX71743 was discovered by Addex and now forms part of the mGlu7 program being advanced by Neurosterix, the neuroscience company launched by Addex and Perceptive Advisors in 2024. 공고 • Jun 09

Addex Therapeutics Demonstrates Solid Anti-Tussive Activity of GABAB PAM Candidate in Bleomycin IPF-Related Chronic Cough Model Addex Therapeutics announced encouraging preclinical data demonstrating antitussive activity of its GABAB positive allosteric modulator (PAM) candidate in a bleomycin (BLM)-induced idiopathic pulmonary fibrosis (IPF) exacerbated chronic cough model. In studies evaluating chronic once-daily (QD) administration of a lead GABAB PAM candidate in BLM-exposed animals, robust and sustained antitussive efficacy was observed, with significant reductions in cough frequency and increased cough latency over the treatment period. Improved lung pathology outcomes, including lower Ashcroft scores and reduced percentage of affected lung tissue suggesting an impact on fibrosis, were demonstrated compared to untreated BLM-exposed animals at both Day 7 and Day 28. The safety profile remained favorable, with no meaningful changes in respiratory rate, or body temperature. The compound was well tolerated throughout the study, supporting its potential for chronic administration. The main inhibitory neurotransmitter GABA activates ionotropic (GABAA) and metabotropic (GABAB) types of receptors. GABAB receptors are widely expressed throughout the central and peripheral cough neural circuit as well as in the lungs and airways. Activating GABAB receptors to treat chronic cough has been clinically validated with baclofen, a selective GABAB agonist, that binds the receptor within the GABA binding, orthosteric site. Baclofen is used off-label to treat chronic cough patients, but its wider use is limited due to serious side effects including sedation, short half-life and gradual loss of efficacy during chronic treatment. Targeting an allosteric site of the receptor encompasses many advantages, including higher selectivity, better tolerability and lack of tolerance compared to an orthosteric compound. 공고 • Apr 22
Addex Therapeutics Ltd Demonstrates Robust Anti-Tussive Activity of Gabab Pam Candidate in Non-Human Primate Chronic Cough Model Addex Therapeutics Ltd. announced robust anti-tussive activity of its novel gamma-aminobutyric acid sub-type B receptor (GABAB) positive allosteric modulator (PAM) in a non-human primate (NHP) chronic cough model. In the NHP model of chronic cough, the GABAB PAM drug candidate significantly reduced citric acid-induced cough frequency. In the same model, the antitussive efficacy of the GABAB PAM drug candidate was similar to that observed with baclofen. As previously reported, in the citric acid induced guinea pig model of chronic cough, the GABAB PAM drug candidate significantly reduced cough frequency, increased cough latency and showed no signs of tolerance after sub-chronic treatment. In the same model, the antitussive efficacy of the GABAB PAM drug candidate appears to be superior to that observed with nalbuphine, baclofen, codeine or a P2X3 inhibitor. In addition, the GABAB PAM candidate demonstrated better tolerability and a wider therapeutic margin than that observed with nalbuphine, baclofen, or codeine, while being similar to that of a P2X3 inhibitor, based on the compound’s activity on respiratory rate. 공고 • Mar 09
