Multicenter Study of Lumateperone for the Treatment of Bipolar Depression in Pediatric Patients

July 3, 2025 updated by: Intra-Cellular Therapies, Inc.

A Randomized, Double-blind, Placebo-controlled, Multicenter Study to Evaluate the Efficacy and Safety of Lumateperone for the Treatment of Major Depressive Episodes (MDEs) Associated With Bipolar I or Bipolar II Disorder (Bipolar Depression) in Pediatric Patients Aged 10 to 17 Years

This is a multicenter, randomized, double-blind, placebo-controlled study in pediatric patients who are experiencing major depressive episodes (MDEs) associated with a primary diagnosis of bipolar I or bipolar II disorder as confirmed by Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM 5).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will be conducted in 3 phases:

  • Screening Period (up to 2 weeks) during which patient eligibility will be assessed
  • Double-blind Treatment Period (6 weeks) during which all patients will be randomized to receive lumateperone or placebo in 1:1 ratio.
  • Safety Follow-up Period (1 week) during which all patients will return to the clinic for a safety follow-up (SFU) visit approximately one week after the last dose of study drug.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

No

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
Children's Depression Rating Scale-Revised (CDRS-R)
Time Frame: Week 6
The Children's Depression Rating Scale-Revised is an observer-rated, 17-item semi-structured scale for pediatric patients. The scale comprises cognitive, somatic, affective, and psychomotor symptoms of depression. Items are rated for severity on a 7-point scale (1 to 7) for 14 items and on a 5-point scale (1 to 5) for three items. Total scores range from 7 to 113.
Week 6

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
Measure Description
Time Frame
Clinical Global Impression Scale-Severity (CGI-S)
Time Frame: Week 6
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).

Primary Completion (Estimated)

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.
