What is being measured
The primary outcome is the main question the study is designed to answer.
Young Mania Rating Scale (YMRS)
The YMRS is an 11-item, clinician-administered mania rating scale designed to assess the severity of manic symptoms. Four of the YMRS items are rated on a 0 to 8 scale, with the remaining 7 items rated on a 0 to 4 scale. The total score ranges from 0 to 60 with a higher score indicating increased severity of manic symptoms.
Measured: Week 3
Secondary outcomes (1)
Clinical Global Impression Scale-Severity (CGI-S)
The CGI-S is a clinician-rated scale to assess a patient's overall mental health. The scale ranges from 1 (normal, not at all ill) to 7 (among the most extremely ill patients).
Measured: Week 3

A Phase 3 study testing Lumateperone in people with Bipolar Disorder, Manic, run by Intra-Cellular Therapies, Inc. at 35 sites in 4 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 35 sites in United States, Bulgaria, Serbia, Romania. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Young Mania Rating Scale (YMRS) (time frame: Week 3). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jul 2026; AzTrials last refreshed its copy on 8 Nov 2026.
