Clinical Trial Evaluating ITI-007 (Lumateperone) as a Monotherapy for the Treatment of Bipolar Depression

October 21, 2025 updated by: Intra-Cellular Therapies, Inc.

A Phase 3, Randomized, Double-Blind, Placebo-Controlled, Multi-Center Study With an Open-Label Extension to Assess the Efficacy and Safety of ITI-007 Monotherapy in the Treatment of Patients With Major Depressive Episodes Associated With Bipolar I or Bipolar II Disorder (Bipolar Depression)

The study will evaluate the efficacy and safety of ITI-007 (Lumateperone) in patients diagnosed with Bipolar I or Bipolar II disorder having a major depressive episode. The study will be conducted in two parts, Part A and Part B. Part A is a randomized, double-blind, placebo-controlled study. In Part B, patients who safely complete participation in part A may be enrolled in an open-label extension.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline to Day 43 in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score
Time Frame: 6 weeks
The Montgomery-Åsberg Depression Rating Scale (MADRS) is a clinician-rated 10 item scale to assess depressive symptoms. Each item is rated on a 7-point scale from 0-6. The total score ranges from 0 to 60 with a higher score indicating increased severity of depressive symptoms.
6 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Time to First Sustained Response in Reduction of MADRS Total Score
Time Frame: 6 weeks
6 weeks

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline to Day 175 in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score
Time Frame: Day 175
The MADRS total score from baseline to Day 175 for patients that rolled over into the extension portion of the study (Part B)
Day 175
Adverse Events
Time Frame: Day 175

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
