• Patients with a body mass index [BMI = body weight (kg)/height (m)²] of 18.5 kg/m² or higher and lower than 35.0 kg/m² at screening

• Patients who, in the judgment of the investigator, have stable psychotic symptoms maintained by administration of an antipsychotic within the dosing range indicated below, before commencement of IMP administration [Upper limit of dose and regimen] Antipsychotic medication comprising no more than 2 active components, and a daily dose equivalent to =600 mg/day of chlorpromazine

• Patients who are able to finish the high-fat meal specified in this protocol within 20 minutes

Exclusion Criteria:

• Patients with a concurrent mental disorder besides schizophrenia who are judged by the investigator to be unsuitable for participation in the trial

• 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 before commencement of investigational medicinal product (IMP) administration

• Patients who fall under any of the following criteria regarding suicidal ideation and suicidal behavior

• Patients who answered "yes" to Question 4 "Active Suicidal Ideation with Some Intent to Act, without Specific Plan" or Question 5 "Active Suicidal Ideation with Specific Plan and Intent" regarding C-SSRS suicidal ideation at screening (for the past 6 months) or at the Period 1 baseline examination (since the last assessment)

• Patients who exhibited suicidal behavior on C-SSRS at screening (for the past 2 years) or at the Period 1 baseline examination (since the last assessment)

• Patients who present a serious risk of suicide based on the judgment of the investigator

• Patients who have previously undergone gastrointestinal surgery that could affect PK evaluation

• Patients who have a clinically significant neurological, hepatic, renal, metabolic, hematological, immunological, cardiovascular, pulmonary, or gastrointestinal disorder. Medical conditions that are minor or well-controlled may be considered acceptable if the condition does not interfere with safety and PK assessments.
