Conditions

Alzheimer's disease

Brief summary

Safety and Tolerability: Adverse events (AEs); physical and neurological examination results; global assessment of tolerability; vital signs; brain MRI assessment; electrocardiogram (ECG); routine hematology and biochemistry evaluation in blood and urine; inflammatory and autoimmune markers in blood and CSF; suicidality as measured with Columbia-Suicide Severity Rating Scale (C-SSRS).

Detailed description

Pharmacodynamic (Immunogenicity): Anti-Aβ antibody titers in serum (eg, geometric mean of antibody titers, change from baseline, responder rate, peak, and area under the curve [AUC]).
