Study Endpoints

Primary Endpoints

Percentage of Participants Experiencing Adverse Events (AEs)
Up to approximately 40 weeks

An adverse event (AE) is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with the treatment. The investigator assesses the relationship of each event to the use of study drug.

Percentage of Participants with Abnormal Change from Baseline in Clinical Laboratory Test Results
Up to approximately 40 weeks

Number of participants with abnormal change in clinical laboratory test results like hematology will be assessed.

Percentage of Participants With Amyloid-Related Imaging Abnormalities (ARIA)
Up to approximately 40 weeks

Amyloid related imaging abnormalities represent a spectrum of magnetic resonance imaging findings primarily observed in participants undergoing treatment with anti-amyloid therapies.

Percentage of Participants with Abnormal Change From Baseline in Vital Sign Measurements
Up to approximately 40 weeks

Number of participants with abnormal change from baseline in vital sign measurements like systolic and diastolic blood pressure will be assessed.

Percentage of Participants with Abnormal Change From Baseline in Electrocardiograms (ECGs) Parameters
Up to approximately 40 weeks

12-lead resting ECGs will be recorded. Parameters include heart rate, PR interval, QT interval, QRS duration, and QT interval corrected using Fridericia's formula (QTcF).

Percentage of Participants Experiencing Any Suicidal Ideation or Suicidal Behavior As Assessed by Columbia-Suicide Severity Rating Scale (C-SSRS)
Up to approximately 40 weeks

The C-SSRS is a clinician-rated instrument that reports the severity of both suicidal ideation and behavior, with a higher score denoting more severe suicidal ideation and behavior.
