Primary Outcome Measures

Name	Time	Method
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 5	From baseline up to Week 5	The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity of participants with schizophrenia and is widely used in the study of antipsychotic therapy. The PANSS rating form contains 7 positive symptom scales, 7 negative system scales, and 16 general psychopathology symptom scales. Participants are rated from 1 to 7 on each symptom scale. The positive symptoms in schizophrenia are the excess or distortion of normal function such as hallucinations, delusions, grandiosity, and hostility, and the negative symptoms in schizophrenia are the diminution or loss of normal functions. PANSS total score is the sum of all 30 items with a minimum score of 30 and a maximum score of 210. Higher scores indicate more severe symptoms. The PANSS Total Score is then the sum of the positive, negative, and general psychopathology symptom scores. Baseline is defined as the PANSS score at screening.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Positive Score at Week 5	From baseline up to Week 5	PANSS positive score is the sum of all PANSS 7 positive symptom scales with a minimum score of 7 and a maximum score of 49. Higher scores indicate more severe symptoms. Participants are rated from 1 to 7 on each symptom scale. The positive symptoms in schizophrenia are the excess or distortion of normal function such as hallucinations, delusions, grandiosity, and hostility. If a patient has a PANSS assessment recorded and no more than 2 items are missing from the PANSS positive scales, then the PANSS Positive Score will be calculated as the average of the non-missing items multiplied by 7. If 3 or more items are missing (\> 30%) at a particular visit, the respective positive score at the visit will not be calculated and will be treated as missing data. Baseline is defined as the PANSS score at screening.
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Negative Score at Week 5	From baseline up to Week 5	PANSS negative score is the sum of all PANSS 7 negative symptom scales with a minimum score of 7 and a maximum score of 49. Higher scores indicate more severe symptoms. Participants are rated from 1 to 7 on each symptom scale. The negative symptoms in schizophrenia are the diminution or loss of normal functions. If a participant has a PANSS assessment recorded, and no more than 2 items are missing from the PANSS negative scales, then the PANSS Negative Score will be calculated as the average of the non-missing items multiplied by 7. If 3 or more items are missing (\> 30%) at a particular visit, the respective negative score at the visit will not be calculated and will be treated as missing data. Baseline is defined as the PANSS score at screening.
Positive and Negative Syndrome Scale (PANSS) Negative Marder Factor Score Change From Baseline at Week 5	From baseline up to Week 5	PANSS Marder factor score is the sum of 5 negative scales and 2 general scales (N1. Blunted affect; N2. Emotional withdrawal; N3. Poor rapport; N4. Passive/apathetic social withdrawal; N6. Lack of spontaneity; G7. Motor retardation; and G16. Active social avoidance). Participants are rated from 1 to 7 on each symptom scale. Higher score indicates more severe symptoms. The negative symptoms in schizophrenia are the diminution or loss of normal functions. Baseline is defined as the PANSS score at screening.
Clinical Global Impression-Severity (CGI-S) Score Change From Baseline at Week 5	From baseline up to Week 5	Clinical Global Impression-Severity (CGI-S) Score is a measurement to evaluate severity and treatment response in schizophrenia. Completed independently by a clinician, the CGI-S assesses extremely ill patients, by asking 1 question and providing a rating based upon observed and reported symptoms, behavior, and function in the past 7 days to reflect the average severity level across the 7 days. Higher score indicates more severe illness. The CGI-S categorizes the severity of the illness as: 1 = Normal, not at all ill; 2 = Borderline mentally ill; 3 = Mildly ill; 4 = Moderately ill; 5 = Markedly ill; 6 = Severely ill; and 7 = Among the most extremely ill patients. This scale reflects the total score. Baseline is defined as CGI-S score at screening. The change from baseline in total score is reported.
Number of Participants Experiencing Cholinergic Symptom Adverse Event	From first dose up to Day 42	The number of participants experiencing adverse events related to procholinergic symptoms (believed to be associated with xanomeline) and anticholinergic symptoms (believed to be associated with trospium) symptoms. Examples of procholinergic symptoms include vomiting, nausea, diarrhea, sweating and hyper-salivation. Examples of anticholinergic include dizziness, confusion, hallucinations, and somnolence.
Number of Participants Who Achieve >=30% Reduction in Positive and Negative Symptoms Scale (PANSS) Total Score From Baseline to Week 5	From baseline up to Week 5	Positive and Negative Syndrome Scale (PANSS) is a scale used for measuring symptom severity of subjects with schizophrenia and is widely used in the study of antipsychotic therapy. The PANSS rating form contains 7 positive symptom scales, 7 negative system scales, and 16 general psychopathology symptom scales. Subjects are rated from 1 to 7 on each symptom scale. The positive symptoms in schizophrenia are the excess or distortion of normal function such as hallucinations, delusions, grandiosity, and hostility, and the negative symptoms in schizophrenia are the diminution or loss of normal functions. PANSS total score is the sum of all 30 items with a minimum score of 30 and a maximum score of 210. Higher scores indicate more severe symptoms. The PANSS Total Score is then the sum of the positive, negative, and general psychopathology symptom scores. Baseline is defined as screening.; Note: Floor adjusted data were used for this analysis. Floor adjusted total score = total score - 30.
Number of Participants Experiencing Adverse Events (AEs)	From first dose up to Day 42	An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in a clinical investigation participant administered study treatment and that does not necessarily have a causal relationship with this treatment. Adverse events are graded on a scale from 1 to 5, with Grade 1 being mild and asymptomatic; Grade 2 is moderate requiring minimal, local or noninvasive intervention; Grade 3 is severe or medically significant but not immediately life-threatening; Grade 4 events are usually severe enough to require hospitalization; Grade 5 events are fatal.
Area Under the Plasma Concentration-Time Curve (AUC)	At days 8 and 28	AUC is the total area under the plasma drug concentration-time curve from time zero to 12 hours after drug administration. Dose level 125/30 BID at Week 4 (Visit 8 \[Day 28\]) is reported.

It is a 10-item testing instrument used to assess gait, arm dropping, shoulder shaking, elbow rigidity, wrist rigidity, leg pendulousness, head dropping, glabella tap, tremor, and salivation. The range of scores is from 0 to 40 with increased scores indicating increased severity. Baseline is defined as the Simpson-Angus Scale score recorded on Day -1.
Change From Baseline in Barnes Akathisia Rating Scale (BARS) Total Score	From baseline up to week 5	The BARS for akathisia is a rating scale used to assess the severity of drug-induced akathisia, or restlessness, involuntary movements and inability to sit still. The range of scores is 0 to 14, with higher scores indicating greater severity. Baseline is defined as the BARS score recorded on Day -1.
Change From Baseline in Abnormal Involuntary Movement Scale (AIMS) Total Score	From baseline up to week 5	The AIMS is a rating scale that is used to measure involuntary movements known as tardive dyskinesia, which can sometimes develop as a side effect of long-term treatment with antipsychotic medications. This measurement was a 12-item scale to assess orofacial, extremity, and truncal movements as well as the overall severity, incapacitation, and the participant's level of awareness of the movements. Items are scored from 0 (none) to 4 (severe). A higher score indicates more severe dyskinesia. Baseline is defined as the AIMS score recorded on Day -1. The total score is the sum of sub scores for items 1-7. The first 7 items are used to measure the severity of abnormal movements in the orofacial region (4 items: facial muscles, lips, jaw, tongue), upper extremities (1 item), lower extremities (1 item), and trunk (1 item). Change from baseline for the total scores are reported.
