Key Inclusion Criteria:

  • Is willing and able to provide written informed consent to participate in the study.
  • Has an identified reliable informant.
  • Is, in the investigator's opinion, suitable for initiating a washout from the subject's current antipsychotic regimen, if applicable, and is willing to abstain from prohibited psychotropic medications in accordance with study requirements.

    • Subjects must meet screening eligibility criteria and be in an inpatient setting prior to discontinuing antipsychotic medications.
    • Subject must be able, in the investigator's opinion, to safely discontinue prohibited psychotropic medications prior to Baseline without increased suicidality.
  • Has a primary diagnosis of schizophrenia based on the Diagnostic and Statistical Manual 5th edition (DSM-5) criteria and confirmed by Mini International Neuropsychiatric Interview (MINI) for Psychotic Disorders Studies.
  • Is experiencing an acute exacerbation or relapse of symptoms.
  • Is in generally good physical health, in the investigator's opinion, based on Screening medical history, physical examination, vital signs, and clinical laboratory values.
  • Has a body mass index (BMI) between 18 and 40 kg/m2, inclusive.
  • For women of reproductive potential: has a negative serum pregnancy test at Screening and a negative urine pregnancy test at Baseline.
  • For women of reproductive potential and men with female partners of reproductive potential: agrees to remain abstinent from sexual intercourse or use adequate and reliable contraception throughout the study and for at least 30 days after the last dose of study drug.

Key Exclusion Criteria:

  • Is a woman who is pregnant, breastfeeding, or less than 6 months postpartum at Screening.
  • Has any primary DSM-5 disorder other than schizophrenia, as confirmed by the MINI.
  • Fails to discontinue prohibited psychotropic medications.

  • Is currently hospitalized involuntarily or incarcerated.
  • Has a history or presence of any clinically significant medical condition, disease, or surgical history that could, in the investigator's opinion, jeopardize the safety of the subject or validity of the study data, or interfere with the absorption, distribution, metabolism, or excretion of the study drug.
  • Is, in the investigator's opinion, not a suitable candidate for the study.

Change from Baseline in Pulse Rate (beats per minute)
Pulse rate is measured by sphygmomanometer. Change from baseline measurement will be calculated
Change from Baseline in Body Temperature (degrees celsius)
Body temperature is measured by oral thermometer. Change from baseline measurement will be calculated
Change from Baseline in Body Weight (kilograms)
Body weight is measured by weight scale. Measurement is reported in kilograms. Change from Baseline measurement will be calculated.
Change from Baseline in ECG Heart Rate (beats per minute)
Heart rate is measured by 12-lead electrocardiogram (ECG). Change from Baseline measure will be calculated.
Change from Baseline in ECG RR Interval (seconds)

Change from Baseline in ECG PR Interval (milliseconds)
PR interval is measured by 12-lead electrocardiogram (ECG). Change from Baseline measurement will be calculated.
Change from Baseline in ECG QTcF Interval (milliseconds)
QTcF is measured by 12-lead electrocardiogram (ECG). Change from Baseline measurement will be calculated.
Number of Participants with Abnormal Physical Examination Findings
Number of Participants with treatment-emergent suicidal ideation or behavior
Treatment-emergent suicidal ideation and/or behavior will be assessed using the Columbia-Suicide Severity Rating Scale (C-SSRS) assessments
Number of Participants with treatment-emergent abnormal movements
