With ties to the Medical College of Wisconsin, Cytometix is a pharmaceutical development company that is developing CMX-020, a new molecular entity to treat pain. CMX-020 is similar in chemical structure to AM404, the active metabolite in acetaminophen. In animal studies, CMX-020 can be dose titrated to provide levels of analgesia equivalent with traditional opioids. CMX-020 is not a µ-opioid receptor agonist
