简要总结

The purpose of this registry is to compile information on patients who are receiving FDA-approved anti-amyloid mAbs in the course of their clinic visits in the Emory Cognitive Neurology Clinic and in Georgia Memory Net Memory Assessment Clinics.

详细描述

Alzheimer's disease is a devastating neurodegenerative illness impacting millions of Americans including patients and caregivers. Treatments have been limited to symptomatic therapies leading to the pervasive sentiment that 'nothing can be done'; however, recent advances in the field have created excitement and hope for patients, families, and healthcare providers. On 6 January 2023, the anti-amyloid monoclonal antibody (mAb) lecanemab received accelerated approval from the Food and Drug Administration (FDA). A similar medication, donanemab, also recently demonstrated positive results in a large trial. Despite the positive trials, questions remain about anti-amyloid mAbs efficacy as well as how they will perform in a real-world setting. The Centers for Medicare & Medicaid Services (CMS) released a National Coverage Analysis (NCA) Memo with a framework for deploying anti-amyloid mAbs in a way that improves understanding of benefit and harm.

This registry will be managed through Georgia Memory Net (GMN), an initiative that was launched in 2018 to build statewide capacity for early and specific diagnosis of Alzheimer's disease and related dementias (ADRD), improve patient and caregiver support, and provide access to emerging disease modifying therapies. The GMN supports Memory Assessment Clinics (MACs) geographically distributed at 7 sites around the state with common data elements modeled on best practices developed in the Emory University Cognitive Neurology Memory Assessment Clinic over the past 25 years. The GMN infrastructure and care model provides an optimal real-world testing ground for evidence development on the effectiveness, safety, and appropriate use of anti-amyloid mAbs in the Medicare population.

The clinical data for patients treated with anti-amyloid mAbs will be compared to historical clinical data from comparable patients who were seen in GMN clinics prior to availability of anti-amyloid mAbs. Patients in the registry will be followed for the duration of their initial treatment as specified by FDA for specific anti-amyloid monoclonal antibody and subsequent maintenance treatment which is currently unspecified.

The objectives of this registry are to:

Monitor clinical use of FDA approved anti-amyloid mAbs to report health outcomes for patients in broad community practice.
Understand how patient characteristics, treating clinicians, and clinical settings impact benefits and harms (brain hemorrhage and edema) of FDA approved anti-amyloid mAbs.
Define how benefits and harms of FDA approved anti-amyloid mAbs change over time.

研究组 & 干预措施

Caregivers of Patients Receiving Anti-amyloid Monoclonal Antibodies (mAbs)

Caregivers of patients with Mild Cognitive Impairment (MCI) or mild AD dementia who are receiving treatment with anti-amyloid mAbs, per standard of care. Caregivers of patients seen in the Emory and GMN MACs are evaluated with standard instruments for cognitive and functional abilities.

干预措施: Anti-amyloid Monoclonal Antibodies (mAbs) (Drug)

Historical Comparator Group

Available historical data from biomarker-confirmed patients with MCI or mild dementia due to AD who have been followed in the Emory Cognitive Neurology Clinic will serve as a comparator group. Patients seen in the Emory and GMN MACs are evaluated with standard instruments for cognitive and functional abilities.

干预措施: Standard of Care (Combination Product)
