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.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

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

9 years to 13 years (Child)

Accepts Healthy Volunteers

No

Description

Main Inclusion Criteria:

  • Male or female patients between 13 and 17 years of age, inclusive
  • Clinical diagnosis of schizophrenia or schizoaffective disorder according to Diagnostic and Statistical Manual of Mental Disorders (DSM-5)
  • Free from acute exacerbation of their psychosis for at least 3 months prior to Screening
  • Clinical Global Impression - Severity (CGI-S) score ≤ 4
  • Body mass index (BMI) within 2 standard deviations of, age- and gender-specific body measurements (based on CDC Clinical Growth Chart, 2000)
  • Ability to swallow capsules

Main Exclusion Criteria:

  • Has a primary psychiatric diagnosis other than schizophrenia or schizoaffective disorder
  • Reports having experienced suicidal ideation within 6 months prior to Screening, any suicidal behavior within 2 years prior to Screening based on the Columbia-Suicide Severity Rating Scale (C-SSRS), and/or the investigator assesses the patient to be a safety risk to him/herself or others
  • Clinically significant abnormality within 2 years of Screening that in the Investigator's opinion may place the patient at risk or interfere with study outcome variables
  • History of a clinically significant cardiac disorder and/or abnormal screening electrocardiogram (ECG) or a QT interval corrected for heart rate using Fridericia formula > 450 msec in males or > 470 msec in females

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
Pharmacokinetics: Cmax
Time Frame: Day 1 and Day 5
Maximum plasma concentration of lumateperone
Day 1 and Day 5
Pharmacokinetics: Tmax
Time Frame: Day 1 and Day 5
Time of maximum concentration of lumateperone in plasma
Day 1 and Day 5
Pharmacokinetics: t1/2

Terminal elimination half-life of lumateperone
Day 1 and Day 5
Pharmacokinetics: CL/F

Day 1 and Day 5
Pharmacokinetics: AUC0-t

0 to 24 hours post-dose on Day 1 and Day 5
Pharmacokinetics: AUC0-tau
Time Frame: 0 to 24 hours post-dose on Day 1 and Day 5
Area under the plasma lumateperone concentration time curve from time zero to the end of dosing (tau)
0 to 24 hours post-dose on Day 1 and Day 5

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
Percentage of Subjects With Treatment-emergent Adverse Events
Time Frame: up to 30 days after last dose, up to a total of 35 days
up to 30 days after last dose, up to a total of 35 days
Change From Baseline in Systolic and Diastolic Blood Pressure
Time Frame: Baseline and Day 6
Baseline and Day 6
Change From Baseline in ECG QT Interval
Time Frame: Baseline and Day 6
QTcF
Baseline and Day 6
Change From Baseline in Hemoglobin
Time Frame: Baseline and Day 6
Baseline and Day 6

Baseline and Day 6
Change From Baseline in Alanine Aminotransferase
Time Frame: Baseline and Day 6
Baseline and Day 6
Change From Baseline in Abnormal Involuntary Movement Scale (AIMS)
Time Frame: Baseline and Day 6
AIMS is a measure of facial and oral movements, extremity movements and trunk movements. The AIMS total score is reported based on 7 items (items 1 through 7). Each item is rated on a scale from none (0) to severe (4). The AIMS total score ranges from 0 to 28. Higher values of total AIMS score indicate increased severity in abnormal movement.
