August 7, 2026 updated by: BioXcel Therapeutics Inc

A Randomized, Double-blind, Placebo-controlled Study to Determine Efficacy and Safety of BXCL501 in Agitation Associated With Pediatric Schizophrenia and Bipolar Disorder

This is a study of the efficacy and safety of BXCL501 in children and adolescents with acute agitation and either bipolar disorder or schizophrenia.

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 enroll approximately 140 subjects randomized to dose regimens of 80 µg or 120 µg BCXL501 or placebo (Group one), or 60 µg BCXL501 or placebo (Group two; Europe only). Subjects with acute agitation will include male and female children and adolescents who are either newly admitted to a hospital setting or already admitted and experiencing acute agitation. Subjects will be domiciled in a clinical research setting or hospitalized to remain under medical supervision while undergoing screening procedures to assess eligibility. Efficacy and safety assessments will be conducted periodically before and after dosing.

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

10 years to 17 years (Child)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Male and female subjects between the ages of 10-17 years, inclusive, with bipolar disorder (DSM-5 criteria) and 13-17 years, inclusive, in subjects with schizophrenia (DSM-5 criteria).
  2. Patients who are judged to be clinically agitated at Screening and Baseline with a total score of ≥14 on the 5 items comprising the PANSS Excited Component (PEC).
  3. Patients who have a score of ≥ 4 on at least 1 of the 5 items on the PEC at Baseline.
  4. Participants who agree to use a medically acceptable and effective birth control method

Exclusion Criteria:

  1. Patients with agitation caused by acute intoxication, including alcohol or drugs of abuse (with the exception of THC) during urine screening.
  2. Use of benzodiazepines or other hypnotics or oral or short-acting intramuscular antipsychotic drugs in the 4 hours before study treatment.
  3. Patients who are judged to be at significant risk of suicide.
  4. Patients with serious or unstable medical illnesses.
  5. Patients who have received an investigational drug within 30 days prior to the current agitation episode.
  6. Patients who are considered by the investigator, for any reason, to be an unsuitable candidate for receiving the study drug.

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
Absolute change from baseline in the Positive and Negative Syndrome Scale - Excited Component (PEC) total score
Time Frame: 120 minutes - Group one only
The Positive and Negative Syndrome Scale - Excited Component (PEC) comprises 5 items associated with agitation: poor impulse control, tension, hostility, uncooperativeness, and excitement; each scored 1 (minimum) to 7 (maximum). The PEC, the sum of these 5 subscales, thus ranges from 5 (absence of agitation) to 35 (extremely severe)
120 minutes - Group one only

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
Absolute change from baseline in the Positive and Negative Syndrome Scale - Excited Component (PEC) total score
Time Frame: 90, 60, 45, 30, 20,10 minutes - Group one only
The Positive and Negative Syndrome Scale - Excited Component (PEC) comprises 5 items associated with agitation: poor impulse control, tension, hostility, uncooperativeness, and excitement; each scored 1 (minimum) to 7 (maximum). The PEC, the sum of these 5 subscales, thus ranges from 5 (absence of agitation) to 35 (extremely severe)
90, 60, 45, 30, 20,10 minutes - Group one only
