Study Endpoints

Primary Endpoints

Part A: Safety and Tolerability Assessments Based on Treatment Emergent Adverse Events (TEAEs) and Validated Clinical Scales
Up to 53 days

An AE is any untoward medical occurrence in a participant or clinical trial participant, temporally associated with the use of trial intervention, whether or not considered related to the trial intervention. Any AE occurring following the start of treatment or occurring before treatment but increasing in severity afterward were counted as treatment-emergent AE (TEAE). Clinically significant abnormalities in Clinical Laboratory Evaluations, ECGs, Vital Signs, Physical examinations, and Columbia Suicide Severity Rating Scale (C-SSRS) scores will be reported as TEAEs.

Part B: Safety and Tolerability Assessments Based on Treatment Emergent Adverse Events and Validated Clinical Scales
Up to Week 10

An AE is any untoward medical occurrence in a participant or clinical trial participant, temporally associated with the use of trial intervention, whether or not considered related to the trial intervention. Any AE occurring following the start of treatment or occurring before treatment but increasing in severity afterward were counted as a TEAE. Clinically significant abnormalities in Clinical Laboratory Evaluations, ECGs, Vital Signs, Physical examinations, and C-SSRS scores will be reported as TEAEs.

Part B: Change from Baseline to Week 8 on the Cohen-Mansfield Agitation Inventory (CMAI) Total Score
Baseline to Week 8

The CMAI is a 29-item scale to assess the frequency of agitated behaviors. The 29 agitated behaviors are categorized into agitation factors, including aggressive behavior, physically non-aggressive behavior, and verbally agitated behavior. Each item is rated over the past 2 weeks on a 7-point scale ranging from "Never" (score of 1) to "Several times per hour" (score of 7). The CMAI total score is calculated as the sum of all 29 items and range from 29 (no agitation) to 203 (most severe agitation). A score \>45 is commonly regarded as clinically significant agitation.
