An adverse event is defined as as any untoward medical occurrence in a clinical trial participant administered a medicinal product and which does not necessarily have a causal relationship with this treatment. A Treatment-Emergent Adverse Event (TEAE) is defined as an adverse event that occurs after treatment has begun.
Part A: Percentage of Participants who Experience a Clinically Significant Change from Baseline in Vital Signs [Baseline (Day -1) to Day 11]
Vital signs will include blood pressure, heart rate, temperature, and respiratory rate.
Part A: Percentage of Participants who Experience a Significant Change from Baseline in ECGs [Baseline (Day -1) to Day 11]
Standard 12-lead electrocardiograms will be used.
Part A: Percentage of Participants who Experience a Significant Change from Baseline in Clinical Laboratory Tests [Baseline (Day -1) to Day 15]
Clinical laboratory tests will be conducted at scheduled time points during Part A and Part B, including hematology, urinalysis, serum chemistry, drug screen and additional tests.
Part A: Change from Baseline in Columbia-Suicide Severity Rating Scale Score [Baseline (Day -1) and Day 15]
Suicidality will be monitored throughout the trial using the C-SSRS (Columbia-Suicide Severity Rating Scale). This scale consists of a baseline evaluation that assesses the lifetime experience of the subject with suicide events and suicidal ideation and a post-baseline evaluation that focuses on suicidality since the last assessment.The Baseline/ Screening Version and the Since Last Visit version of the C-SSRS will be completed by trained trial site staff at each visit. A numerical score will correspond to one of ten categories relating to suicidal ideation and suicidal behavior. A higher score indicates a higher risk of suicidal behavior, but an answer of 'yes' to any question indicates some risk.

Part B: Percentage of Participants who Experience at Least One Treatment-Emergent Adverse Event [Day 1 to End of Follow-Up (Day 34 [+ 2 Days])]
An adverse event is defined as as any untoward medical occurrence in a clinical trial participant administered a medicinal product and which does not necessarily have a causal relationship with this treatment. A Treatment-Emergent Adverse Event (TEAE) is defined as an adverse event that occurs after treatment has begun.
Part B: Percentage of Participants who Experience a Clinically Significant Change from Baseline in Vital Signs [Baseline (Day -1) to Day 6]
Part B: Percentage of Participants who Experience a Significant Change from Baseline in ECGs [Baseline (Day -1) to Day 6]

Must have a current diagnosis of schizophrenia or bipolar disorder, as determined by the Diagnostic and Statistical Manual of Mental Disorders Version 5 (DSM-5) criteria.
Must have a Body Mass Index between 18 and 35 kg/m^2.
Good physical health as determined by no clinically significant deviation from normal, in the opinion of the investigator, in medical history, clinical laboratory determination, ECGs, or physical examinations.
Participants must be considered stable, per the investigator's judgment, on one of the following atypical oral antipsychotic medications at an adequate dose (eg, low- to mid-range of the recommended dose range for the treatment of schizophrenia or bipolar disorder, according to the manufacturer labeling) and for an adequate duration (30 days) prior to the administration of IMP: aripiprazole, brexpiprazole, risperidone, olanzapine, quetiapine, ziprasidone, paliperidone, cariprazine, lurasidone, and asenapine. Other oral antipsychotic medications may be allowed if approved by the medical monitor and sponsor; however, clozapine will not be allowed. Per the investigator's judgment, they should be comfortable with the participant discontinuing background antipsychotic therapy during the trial period and then restarting the antipsychotic therapy once trial participation has been completed.
