About this trial

The primary purpose of this study is to evaluate the safety of lecanemab-irmb in the real-world clinical setting as reported by events of amyloid-related imaging abnormalities (ARIA)-edema (ARIA-E), ARIA-hemosiderin deposition (ARIA-H), symptomatic ARIA-E, symptomatic ARIA-H, and intracerebral hemorrhage (ICH) greater-than 1 cm in participants treated with lecanemab-irmb.

The secondary purpose of this study is to:

Evaluate the safety of lecanemab-irmb in the real-world clinical setting as reported by events of seizures, anaphylaxis, central nervous system (CNS) ischemic event, and death.

Assess the safety of lecanemab-irmb when stratified by baseline characteristics including apolipoprotein E (APOE) genotype, baseline magnetic resonance imaging (MRI) findings consistent with a high risk for cerebral amyloid angiopathy (CAA), prior Alzheimer's Disease (AD) treatments, and antithrombotic therapy.

Assess the risk of safety outcomes (ARIA-E, ARIA-H, ICH greater than 1 cm, seizures, anaphylaxis, CNS ischemic event, and death) associated with APOE genotype, baseline MRI findings consistent with high risk for CAA, prior AD treatment, and antithrombotic therapy within participants exposed to lecanemab-irmb in ALZ-NET.

Assess the risk of safety outcomes (ARIA-E, ARIA-H, ICH greater than 1 cm, seizures, anaphylaxis, CNS ischemic event, and death) between participants exposed to lecanemab-irmb in ALZ-NET and subjects exposed to lecanemab irmb in Study 301.

Assess the risk of safety outcomes (ARIA-E, ARIA-H, ICH greater than 1 cm, seizures, anaphylaxis, CNS ischemic event,and death) between participants exposed to lecanemabirmb in ALZ-NET and subjects exposed to placebo (PBO) in Study 301.

Assess the risk of safety outcomes (ARIA-E, ARIA-H, ICH greater than 1 cm, seizures, anaphylaxis, CNS ischemic event, and death) between participants exposed to lecanemab-irmb in ALZ-NET and participants not exposed to anti-amyloid therapies in ALZ-NET.

Assess whether the risk of safety outcomes associated with APOE genotype, baseline MRI findings consistent with high risk for CAA, prior Alzheimer's Disease treatments, and antithrombotic therapy differs between participants exposed to lecanemab-irmb in ALZ-NET versus those not exposed to anti-amyloid therapies in ALZ-NET.

Trial outcomes

Primary outcomes

1

Incidence and exposure-adjusted incidence rate of the adverse events of special interest (AESIs) of ARIA-E, symptomatic ARIA-E, ARIA-H, symptomatic ARIA-H, and ICH greater-than 1 cm in diameter

Time frame
Baseline up to Follow-up, up to 10 years

Secondary outcomes

1

Incidence and exposure-adjusted incidence rate of seizure, anaphylaxis, central nervous system (CNS) ischemic event, and Death

Time frame
Baseline up to Follow-up, up to 10 years
2

Incidence Rate of AESIs

Incidence and exposure-adjusted incidence rate of AESIs will be assessed by count (n) and proportion (%) of APOE genotype, baseline MRI findings consistent with a high risk for CAA, prior AD treatments, and antithrombotic therapy.

Time frame
Baseline up to Follow-up, up to 10 years
