Name: Lumateperone
Synonyms: ITI-007
Therapy Type: Small Molecule (timeline)
Target Type: Other Neurotransmitters (timeline)
Condition(s): Alzheimer's Disease, Schizophrenia, Bipolar Disorder
U.S. FDA Status: Alzheimer's Disease (Phase 3), Schizophrenia (Phase 3), Bipolar Disorder (Phase 3)
Company: Bristol-Myers Squibb, Intra-Cellular Therapies, Inc.


This serotonin 5-HT2A receptor antagonist was originally developed by Bristol Myers Squibb and licensed to Intra-cellular Therapies in 2005. This company is testing ITI-007 clinically for schizophrenia, bipolar depression, and insomnia, as well as for the treatment of agitation in dementia, including Alzheimer's disease.

This compound is being studied at different dose levels. At low doses, it reportedly engages primarily the 5-HT2A receptor, whereas at higher doses it also affects dopamine receptors, enhances glutamatergic transmission, and inhibits serotonin reuptake (see see Davis et al., 2015Snyder et al., 2015Davis et al., 2016).


In 2014, Intra-Cellular Therapies ran a Phase 1/2 dose-escalation study of up to 30 mg/d in 30 old healthy volunteers and people with a clinical diagnosis of dementia. This trial measured safety, exposure and, as exploratory outcomes, cognitive function and sleep. Agitation was to be measured but did not occur in this patient sample. Results were presented at the 2014 CTAD conference (see Dec 2014 conference news; Dec 2015 conference news).  

In June 2016, a Phase 3 study began enrolling an anticipated 360 participants with a clinical diagnosis of Alzheimer's and agitation. The study will evaluate a one-month course of 9 mg/d of ITI-007 against placebo on the Cohen-Mansfield Agitation Inventory-Community version (CMAI-C) and the Clinical Global Impression for Severity of Illness (CGI-S). This trial will run through August 2018.
