New York, May 01, 2024 - PRISM MarketView - Shares in biopharmaceutical company, Addex Therapeutics (Nasdaq: ADXN), dropped on Monday after the company announced topline data from its Phase 2 study of ADX71149 in the treatment of epilepsy. The company’s share price closed up +1.46% on Tuesday after two choppy trading sessions.
ADX71149, which has been found to be safe and well-tolerated, is being investigated for the treatment of patients with focal onset seizures with suboptimal response to levetiracetam or brivaracetam. Data from 110 evaluable patients showed that the compound did not achieve statistical significance for the primary endpoint of time for patients to reach baseline seizure count when added to standard of care.
“While disappointed that the Phase 2 ADX71149 epilepsy study did not meet the primary endpoint, we are still analyzing the data. We will provide details on data from the full study when this analysis is completed and will work with our partner to determine next steps for the ADX71149 program.”
Roger Mills, Chief Medical Officer of Addex
Glutamate plays a key role in the initiation and spread of seizures. ADX71149 is a selective metabotropic glutamate subtype 2 (mGlu2) receptor positive allosteric modulator (PAM). When activated, the mGlu2 receptor decreases the release of glutamate and consequently, helps to maintain neurotransmitter balance. In the presence of agonist-induced activation, positive allosteric modulation of mGlu2 receptors could result in the normalization of the excessive glutamate release seen during a seizure.
Epilepsy is a challenging unmet medical need, and a significant proportion of the patient population struggling in their day-to-day management of seizures.
