ListOutcomeTime frameDescription
PrimaryNumber of Participants With TEAEs From First Dose to End of Study Follow up.From first dose to end of study follow up (63 days)
Number of participants with Treatment Emergent Adverse Events (TEAEs) from first dose to end of study follow up. An adverse event (AE) is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition occurring in a clinical investigation participant after signing of informed consent, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (such as an abnormal laboratory test result), symptom, or disease temporally associated with the study intervention.
PrimaryNumber of Participants With TEAEs at the End of Period 1 and Period 2.Period 1 (From first dose to day 28) Period 2 (day 29 to day 56)
Number of participants with TEAEs at the end of period 1 and period 2. An adverse event (AE) is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition occurring in a clinical investigation participant after signing of informed consent, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (such as an abnormal laboratory test result), symptom, or disease temporally associated with the study intervention.
PrimaryNumber of Participants With Serious TEAEs at the End of Period 1 and Period 2.Period 1 (From first dose to day 28); Period 2 (day 29 to day 56); Overall (63 days)
Number of participants with TEAEs at the end of period 1 and period 2. Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, and requires inpatient hospitalization or causes prolongation of existing hospitalization.
PrimaryNumber of Participants With TEAEs Leading to Treatment Discontinuation.Period 1 (From first dose to day 28); Period 2 (day 29 to day 56); Overall (63 days)Number of participants with TEAEs leading to treatment discontinuation.
PrimaryNumber of Participants With Pro-cholinergic and Anticholinergic TEAEs.Period 1 (From first dose to day 28); Period 2 (day 29 to day 56); Overall (63 days)
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.
SecondaryChange From Baseline in PANSS Total Score, Positive Score and Negative ScoreFrom first dose to end of treatment (56 days)
The Positive and Negative Syndrome Scale (PANSS) assesses schizophrenia symptom severity using 30 items: 7 positive, 7 negative, and 16 general psychopathology scales. Each item is rated from 1 (absent) to 7 (extreme). Positive symptoms represent excesses or distortions of normal function (e.g., hallucinations, delusions), while negative symptoms reflect diminished function. The PANSS positive and negative scores each sum their respective 7 items, ranging from 7 to 49, with higher scores indicating greater severity. The PANSS Total Score sums all 30 items, ranging from 30 to 210, with higher scores reflecting worse overall symptom severity.
SecondaryChange From Baseline in Marder Factor Score.From first dose to end of treatment (56 days)
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, with a total score ranging from 7 to 49. 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.
SecondaryChange From Baseline in CGI Severity ScoreFrom first dose to end of treatment (56 days)
Completed independently by a clinician, 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, by asking the clinical 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.
SecondaryNumber of Participants With Spontaneously Reported AESIsFrom first dose to end of study follow up (63 days)
The AEs of special interest (AESIs) will be monitored and include symptomatic orthostasis, syncope(a transient loss of consciousness or fainting),and liver function test elevations as defined below. For SAE reporting requirements for events of liver injury.
SecondaryNumber of Participants With Clinically Significant Changes in Vital SignsFrom first dose to end of study follow up (63 days)Number of participants with clinically significant changes in vital signs
