Who may be able to join

  • Japanese patients who are between 18 and 64 years of age, inclusive, at the time of informed consent
  • Patients with a diagnosis of schizophrenia as defined by the DSM-5® criteria
  • Patients who are able to remain at the trial site for the protocol-defined hospitalization period
  • Patients with a body mass index [BMI = body weight (kg) / height (m)2] of no less than 18.5 kg/m2 and less than 35.0 kg/m2 at screening
  • Patients who are able to provide written informed consent (if the patient is a minor or is hospitalized for medical protection, his or her legally acceptable representative must also give informed consent) prior to commencement of any trial procedure and are judged by the investigator or subinvestigator to be able to meet all protocol-defined requirements

Who cannot join

  • Patients with a diagnosis of a concurrent mental disorder besides schizophrenia (eg, schizoaffective disorder, major depressive disorder, bipolar I disorder, bipolar II disorder, general anxiety disorder, obsessive-compulsive disorder, post-traumatic stress disorder, dementia or mild neurocognitive disorder, and personality disorder) as defined by the DSM-5® criteria. However, this exclusion does not apply to caffeine- or tobacco-related disorders.
  • Patients who fail to meet the mandatory washout periods for the prohibited concomitant drugs and foods before commencement of IMP administration, or patients who are anticipated to take any of the drugs or foods during the trial period
  • Patients who have received electroconvulsive therapy (ECT) within 60 days prior to the administration of IMP
  • Patients with clinically significant nervous, hepatic, renal, metabolic, blood, immune, cardiovascular, respiratory, or digestive system disorders However, such patients may be enrolled if the condition is mild or well controlled and is considered to not affect safety or PK evaluations.
  • Patients who have met the DSM-5® diagnostic criteria for substance-related or addictive disorder, including alcohol and benzodiazepines but excluding caffeine and tobacco, within 180 days prior to the administration of IMP
  • Patients with a positive drug test at screening (according to the results from the central laboratory). However, such patients may be enrolled if their condition is not diagnosed as a substance-related or addictive disorder, according to the DSM-5® diagnostic criteria.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Brexpiprazole LAI: Dose 1, Brexpiprazole LAI: Dose 2 and Brexpiprazole LAI: Dose 3 in people with Schizophrenia, run by Otsuka Pharmaceutical Co., Ltd..

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 6 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: withdrawn, as of the sponsor's last update on 28 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 was withdrawn before enrolling participants, so there are no results.

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?

Plasma concentrations of brexpiprazole (time frame: Blood Sampling for plasma drug measurement Day 1 (predose and 4, 8, 12 hours postdose), 2, 3, 5,7,9,11,13,15,17,19, 21, 25, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 112, 126, 154, 182). 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 28 Apr 2022.
