Problem
Many brain and nervous system disorders lack effective treatments due to the complex nature of neural cell communication. Traditional approaches targeting NMDA receptors have been limited by issues of over-activation or full inhibition, leading to toxicity or significant side effects.
Solution
Aptinyx is a biopharmaceutical company developing therapies for disorders of the brain and nervous system, utilizing a unique platform that modulates NMDA receptors to enhance synaptic plasticity without causing over-activation or inhibition. Their compounds bind to a unique domain on the NMDA receptor, resulting in optimal modulation and a favorable safety profile. This approach aims to restore normal balance in the brain and CNS, offering a potential paradigm shift in treating various neurological and neuropsychiatric conditions. Aptinyx is advancing development candidates across post-traumatic stress disorder, cognitive impairment, and opioid use disorder.
Target Audience
The primary target audience includes individuals suffering from neurological and neuropsychiatric disorders such as post-traumatic stress disorder, cognitive impairment associated with Parkinson’s disease and dementia with Lewy bodies, and opioid use disorder.
