We are utilizing our deep knowledge of drug mechanisms to develop medicines with the potential to provide meaningful differences for people living with psychiatric and neurological conditions.


Our extensive knowledge of how drugs work in the central nervous system fuels our drug discovery and clinical efforts, as we work towards our goal of developing transformative medicines. Our intimate understanding of the biology of muscarinic receptors has propelled our research toward finding novel mechanisms for treating diseases through appropriate activation of the cholinergic system, starting with our lead candidate KarXT.
