Condition: Alzheimer Dementia (AD) · Sponsor: The Methodist Hospital Research Institute
Alzheimer's disease (AD) is the most common cause of dementia. Despite major research efforts, effective treatments that slow or stop disease progression remain limited. Growing evidence suggests that inflammation in the brain and the body plays a key role in the onset and progression of AD. In particular, immune cells called regulatory T cells (Tregs), which normally help control inflammation, are impaired in AD individuals. This leads to increased activity of harmful immune pathways that worsen brain injury. Interleukin-2 (IL-2) is a drug that can restore the function of Tregs. Glucagon-like peptide-1 receptor agonists (GLP-1RAs), such as semaglutide, are a class of drugs currently used to treat diabetes and obesity. Beyond their metabolic effects, GLP-1RAs also reduce inflammation, protect brain cells, and improve cellular energy balance. Laboratory studies, including our own, show that combining IL-2 with semaglutide has stronger effects than either drug alone. Together, they enhance Treg function, dampen harmful inflammatory responses, and improve cell survival. These findings support testing IL-2 plus semaglutide as a novel combination therapy for AD. We now propose a clinical trial to evaluate the safety, feasibility, and biological effects of this strategy. The study will enroll 30 individuals with AD, ages 50 to 86, who have a confirmed diagnosis by amyloid PET brain imaging and a Mini-Mental State Exam score between 16 and 26. Participants will be randomly assigned …
