Brief Summary: The purpose of this research is to investigate the long-term effectiveness and safety of new Alzheimer's disease treatments, particularly monoclonal antibody therapies like lecanemab and donanemab, as well as to enhance diagnostic methods for Alzheimer's disease by collecting real-world data from Korean Alzheimer's patients. The goal is to contribute to the precision of Alzheimer's treatment and to evaluate the impact of these new therapies and diagnostic techniques in clinical practice.
Detailed Description: In 2024, it is estimated that there will be over 1 million individuals aged 65 and older with dementia in South Korea, with national dementia care costs exceeding approximately 17 trillion KRW (0.9% of GDP). South Korea is experiencing rapid population aging, leading to a projected significant increase in both the number of patients and the associated socio-economic costs. Alzheimer's disease (AD) is the most common cause of dementia and cognitive impairment in the elderly, characterized by the abnormal accumulation of amyloid beta (Aβ) and tau proteins in the brain. Research has shown that beta-amyloid protein begins to accumulate in the brain over 20 years before the onset of memory impairment symptoms. Consequently, Alzheimer's disease progresses through a prolonged asymptomatic stage of normal cognitive function (cognitively unimpaired, CU) to subjective cognitive decline, mild cognitive impairment, and dementia.

In May 2024, the Korean Ministry of Food and Drug Safety approved lecanemab for the treatment of Alzheimer's disease. Recent advancements have been made in the development of new treatments and diagnostic methods for Alzheimer's disease, with some already approved for use in South Korea or anticipated to receive approval soon. These developments are expected to significantly impact the management of dementia and cognitive impairment patients in the near future. Among the new treatments, monoclonal antibody injections targeting the core pathological mechanism of Alzheimer's disease, which is the removal of beta-amyloid protein (e.g., lecanemab, donanemab), currently lack long-term efficacy data, providing only 1-2 years of investigatory data in clinical trials. Such medications may have side effects, including amyloid-related imaging abnormalities (ARIA) such as brain edema or microbleeding and infusion-related adverse reactions. For the advancement of precise treatments for Alzheimer's disease, it is essential to monitor long-term effects and side effects of these drugs in clinical practice to collect and analyze more extensive clinical data to establish additional clinical evidence.

Moreover, the phase 3 clinical trial data for lecanemab suggests that the drug's effectiveness and side effects may vary by ethnicity. Recently, a diagnostic technique that measures Elecsys beta-amyloid 42 (Aβ42) and Elecsys Phospho-Tau181 (ptau181) in cerebrospinal fluid (CSF) has received approval from the Korean Ministry of Food and Drug Safety for the diagnosis of Alzheimer's disease. Additionally, there is a strong potential for new diagnostic methods that measure proteins such as ptau217, ptau181, and Aβ42 in blood to be commercialized in clinical practice. Future advancements through real-world data collection on these new diagnostic methods will be necessary.

The Alzheimer's Association (AA) and researchers in the United States have initiated a registry study named the Alzheimer's Network for Treatment and Diagnostics (ALZ-NET) to collect real-world data on new treatments and diagnostic methods for Alzheimer's disease. Longitudinal studies to investigate the long-term effectiveness and safety of new treatments and diagnostic methods in Alzheimer's patients are also being established in countries such as Japan, Australia, the Netherlands, and Europe. In response to these changes in Alzheimer's disease management, the researchers aim to contribute to the precision of Alzheimer's treatment and the enhancement of new diagnostic methods by collecting real-world data from Korean Alzheimer's patients regarding the long-term effectiveness and safety of new therapies.
