2.2 Dementia-Related Psychosis

Early Stage Clinical Programs


ACP-044 is a novel, first-in-class, orally administered, non-opioid analgesic. The mechanism of action is thought to interrupt multiple pain pathways and sensitization of neurons to pain, by accelerating the decomposition of peroxynitrite, a by-product of tissue damage. A Phase 2 study was initiated evaluating ACP-044 for the treatment of postoperative pain following bunionectomy surgery in March 2021. A Phase 2 study evaluating ACP-044 for the treatment of pain associated with osteoarthritis is expected to commence in the second quarter of 2021.


Highly selective positive allosteric modulators (PAMs) of the M1 subtype of the muscarinic acetylcholine receptor may represent a novel approach for improving cognitive function and other neuropsychiatric symptoms in patients suffering from CNS disorders. In our M1 PAM program we are focused on advancing a portfolio of early stage candidates, including our lead candidate which is in early Phase 1 trials.
