- Research Publication: Addex Therapeutics announced new findings demonstrating that ADX71743, a selective negative allosteric modulator, significantly modulates sleep-wake regulation and stress-related neurochemistry in animal models, further validating its therapeutic potential in neurological disorders.
- Mechanism Validation: The study indicates that ADX71743 increases wakefulness while reducing both REM and non-REM sleep in rats, highlighting its crucial role in modulating stress-responsive neural circuits, which may open new avenues for treating anxiety and mood disorders.
- Scientific Basis Strengthened: The results, published in the International Journal of Neuropsychopharmacology, bolster the evidence for mGlu7 as a vital therapeutic target for various central nervous system disorders, enhancing Addex's scientific foundation in this field.
- Future Development Prospects: CEO Tim Dyer noted that the findings of ADX71743 provide strong scientific rationale for Neurosterix's ongoing development, indicating the drug's broad application potential in addressing anxiety, sleep regulation, and related conditions.
