Addex Starts Phase 2 Clinical Study of ADX71149 for Epilepsy
First patients enrolled into multi-center U.S. study
Geneva, Switzerland, June 7, 2021 – Addex Therapeutics (SIX: ADXN and Nasdaq: ADXN), a clinical-stage pharmaceutical company pioneering allosteric modulation-based drug discovery and development, today announced that the first patients have been enrolled into a Phase 2 clinical study evaluating JNJ-40411813 (ADX71149) in patients with epilepsy. JNJ-40411813 (ADX71149) is a selective metabotropic glutamate type 2 (mGlu2) receptor positive allosteric modulator (PAM). The trial is being conducted in collaboration with Janssen Pharmaceuticals, Inc., part of the Janssen Pharmaceutical Companies of Johnson & Johnson.
“Addex is anticipating multiple clinical study catalysts during 2021. The first, starting with this epilepsy study, illustrates the continued commitment of our long-time collaboration partner Janssen Pharmaceuticals, Inc. to this program and to pioneering novel ways to help epilepsy patients. Data from the study are expected in Q3 2022,” said Tim Dyer, CEO of Addex. “The start of additional clinical trials, including our pivotal study for our lead program dipraglurant in Parkinson’s disease patients suffering from dyskinesia remains on track for this quarter.”
The multi-center study (ClinicalTrials.gov Identifier: NCT04836559) will assess the efficacy, safety, tolerability and pharmacokinetics of adjunctive JNJ-40411813 (ADX71149) administration in patients with focal onset seizures with suboptimal response to levetiracetam. The primary objective of the study is to evaluate the efficacy of JNJ-40411813 (ADX71149) in combination with levetiracetam using a time-to-event endpoint.

About Addex Therapeutics
Addex Therapeutics is a clinical-stage pharmaceutical company focused on the development and commercialization of an emerging class of novel orally available small molecule drugs known as allosteric modulators for neurological disorders. Allosteric modulators offer several potential advantages over conventional non-allosteric molecules and may offer an improved therapeutic approach to conventional "orthosteric" small molecule or biological drugs. Addex’s allosteric modulator drug discovery platform targets receptors and other proteins that are recognized as essential for therapeutic intervention. Addex’s lead product candidate, dipraglurant (mGlu5 negative allosteric modulator or NAM), is poised to start a pivotal registration clinical trial for Parkinson’s disease levodopa induced dyskinesia (PD-LID) in Q2 2021. Addex is also investigating dipraglurant's therapeutic use in blepharospasm (a type of dystonia), for which a clinical trial is expected to be initiated in Q2 2021. Addex’s GABAB PAM program has been licensed to Indivior PLC, which is focused on development for the treatment of addiction. Preclinical programs include GABAB PAM for CMT1A, mGlu7 NAM for PTSD, mGlu2 NAM for mild neurocognitive disorders, mGlu4 PAM for Parkinson’s disease and mGlu3 PAM for neurodegenerative 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.
