Study Endpoints

Primary Endpoints

Number of Participants with Treatment Emergent Adverse Events (AEs) during the OLE
Up to 112 Weeks

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention.

Number of Participants with Adverse Event of Special Interest (AESIs) during the OLE
Up to 112 Weeks

AESIs includes Infusion-related reactions, Amyloid related imaging abnormalities (ARIA) and cerebral macrohemorrhage.

Number of Participants with Serious Adverse Events (SAEs) during the OLE
Up to 112 Weeks

A SAE is defined as any untoward medical occurrence that, at any dose, results in death and is life threatening requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability or incapacity, or is a birth defect or congenital anomaly.

Number of Participants with Amyloid related imaging abnormalities (ARIAs) Including Severity during the OLE
Up to 112 Weeks

Magnetic resonance imaging (MRIs) will be used to monitor for abnormalities in the brain such as brain swelling and/or brain bleeding, which are termed as ARIAs.

Change from Baseline in Clinical Dementia Rating - Sum of Boxes (CDR-SB) Score for Dose 1 vs Placebo Across Weeks 52, 64 and 76
Baseline, Week 52, 64 and 76

The CDR-SB score is a quantitative general index that provides more precision in participants with mild dementia. The CDR scale is a clinician-rated dementia staging system tracks the progression of. cognitive impairment in 6 categories (memory, orientation, judgment, and problem solving, community affairs, home and hobbies, and personal care). Each category is scored on a 5- point scale in which None=0, Questionable=0.5, Mild=1, Moderate=2, and Severe=3. The CDR-SB is obtained by adding the ratings in each of the 6 categories and ranges from 0 to 18 with higher scores indicative of greater impairment.
