Addex GABAB PAM Candidate Demonstrates Robust Anti-Tussive Activity in Multiple Chronic Cough Preclinical Models
Ad Hoc Announcement Pursuant to Art. 53 LR Geneva, Switzerland, June 6, 2025 - Addex Therapeutics (SIX: ADXN and Nasdaq: ADXN), a clinical-stage biopharmaceutical company focused on developing a portfolio of novel small molecule allosteric modulators for neurological disorders, announced today robust anti-tussive activity of its novel gamma-aminobutyric acid sub-type B receptor (GABAB) positive allosteric modulator (PAM) in multiple preclinical models of chronic cough compared to reference drugs. Some of these preclinical data with Addex GABAB PAM drug candidate will be presented on June 7, 2025 at the 10th American Cough Conference, in Dulles, Virginia by Dr Mikhail Kalinichev, Head of Translational Science at Addex. In models of chronic cough, the GABAB PAM drug candidate significantly reduced citric acid-induced cough frequency, increased cough latency and showed no signs of tolerance after sub-chronic treatment. In the same model, the antitussive efficacy of the Addex GABAB PAM drug candidate appears to be superior to that observed with nalbuphine, baclofen, codeine or a P2X3 inhibitor. In addition, the tolerability of 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. 'The preclinical data obtained to date demonstrate the huge therapeutic potential of our highly selective GABAB PAM. Following in vivo proof of concept seen in a range of cough models, we are now ready to advance this candidate molecule into IND enabling studies,' said Dr Kalinichev. 'Chronic cough continues to be difficult to treat, and several different approaches being evaluated in clinical trials. Based on the data we have collected to date, we believe our GABAB PAM candidate has the potential to be an effective, once-daily treatment for patients with refractory chronic cough and other conditions.' 'This data with our novel, once daily, orally available GABAB PAM drug candidate clearly demonstrates the potential of our allosteric modulator approach to deliver a better effect than baclofen for this clinically validated drug target,' said Tim Dyer, CEO of Addex. 'Congratulations to the team and we look forward to advancing this candidate rapidly through IND enabling studies and into the clinic so we can hopefully provide better treatment options for patients.' About GABAB activation and cough: The main inhibitory neurotransmitter GABA activates ionotropic (GABAA) and metabotropic (GABAB) types of receptors. GABAB receptors are widely expressed on airways and in the central and peripheral components of the cough neural circuit. 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, 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. About Addex Therapeutics:Addex is a clinical-stage biopharmaceutical company focused on developing a portfolio of novel small molecule allosteric modulators for neurological disorders. Addex's lead drug candidate, dipraglurant (mGlu5 negative allosteric modulator or NAM), is under evaluation for future development in brain injury recovery, including post-stroke and traumatic brain injury recovery. Addex's partner, Indivior, has selected a GABAB PAM drug candidate for development in substance use disorders and has successfully completed IND enabling studies. Addex is advancing an independent GABAB PAM program for chronic cough. Addex also holds a 20% equity interest in a private spin out company, Neurosterix LLC, which is advancing a portfolio of allosteric modulator programs, including M4 PAM for schizophrenia, mGlu7 NAM for mood disorders and mGlu2 NAM for mild neurocognitive disorders. Addex shares are listed on the SIX Swiss Exchange and American Depositary Shares representing its shares are listed on the NASDAQ Capital Market, and trade under the ticker symbol 'ADXN' on each exchange.

Trevi Therapeutics to Host Conference Call and Webcast on June 2nd to Share Topline Results from the Phase 2b CORAL Trial of Haduvio in Patients with Idiopathic Pulmonary Fibrosis Chronic Cough
Conference call and webcast to be held at 8:30 a.m. ET NEW HAVEN, Conn., June 1, 2025 /PRNewswire/ -- Trevi Therapeutics, Inc. (NASDAQ: TRVI), a clinical-stage biopharmaceutical company developing the investigational therapy Haduvio™ (oral nalbuphine ER) for the treatment of chronic cough in patients with idiopathic pulmonary fibrosis (IPF) and in patients with refractory chronic cough (RCC), today announced a conference call and live webcast taking place tomorrow, Monday, June 2nd, 2025, at 8:30 a.m. ET, to share topline results from the Phase 2b CORAL trial of Haduvio in patients with IPF chronic cough. Conference Call/WebcastThe Company will host a conference call and webcast to review the topline results. The live webcast, including audio and presentation slides, will be accessible at the time of the meeting and can be accessed here. To participate in the live conference call by phone, please dial (877) 870 4263 (domestic) or (412) 317 0790 (international) and ask to join the Trevi Therapeutics call.

About Idiopathic Pulmonary Fibrosis (IPF) Chronic CoughChronic cough is a highly prevalent condition in patients with IPF, impacting up to 85% of the IPF population. There are ~140,000 patients in the U.S. with IPF. The impact of chronic cough is significant with patients coughing up to 1,500 times per day. This consistent cough and any associated damage may lead to worsening disease, a higher risk of progression, death, or need for lung transplant. Chronic cough also often leads to a decline in patients' social, physical, and psychological quality of life. There are no approved therapies for the treatment of chronic cough in patients with IPF and current off-label treatment options provide minimal benefit to patients. About Trevi Therapeutics, Inc. Trevi Therapeutics, Inc. is a clinical-stage biopharmaceutical company developing the investigational therapy Haduvio™ (oral nalbuphine extended-release) for the treatment of chronic cough in patients with idiopathic pulmonary fibrosis (IPF) and in patients with refractory chronic cough (RCC). Haduvio is the first and only investigational therapy to show a statistically-significant reduction in cough frequency in clinical trials of patients with IPF chronic cough and in patients with RCC. Haduvio acts on the cough reflex arc both centrally and peripherally as a kappa agonist and a mu antagonist (KAMA), targeting opioid receptors that play a key role in controlling chronic cough. Nalbuphine is not currently scheduled by the U.S. Drug Enforcement Agency. Trevi intends to propose Haduvio as the trade name for oral nalbuphine ER. Its safety and efficacy have not been evaluated by any regulatory authority. For more information, visit and follow Trevi on X (formerly Twitter) and LinkedIn.

There are no approved therapies for the treatment of chronic cough in patients with IPF and current off-label treatment options provide minimal benefit to patients. Refractory chronic cough has no approved therapies in the U.S. and is defined as a persistent cough lasting >8 weeks despite treatment for an underlying condition (i.e., asthma, gastroesophageal reflux disease, non-asthmatic eosinophilic bronchitis, and upper airway cough syndrome or post-nasal drip) and includes unexplained chronic cough. RCC affects ~2-3 million patients in the U.S. and is caused by cough reflex hypersensitivity in both the central and peripheral nerves. It is a highly debilitating disease and accompanied by a wide range of complications, ranging from urinary incontinence in females to sleep disruption and social embarrassment that causes significant social and economic burdens for patients and those around them.
