Researchers are studying the safety and effects of VHB937 in people with early Alzheimers disease, including those with Mild Cognitive Impairment due to Alzheimers or mild Alzheimers itself. This randomized, double-blind, placebo-controlled Phase II trial aims to evaluate whether VHB937 can benefit memory, thinking abilities, daily functioning, and brain changes. The study also looks at how the body processes VHB937 and responds to it. Participants receive intravenous infusions of either a low dose or high dose of VHB937, or a placebo, over a 72-week double-blind period. After this, an extension phase follows for further observation. The treatments are given through infusions, and participants are randomly assigned to one of the three groups in parallel. Throughout the study, participants and their study partners attend regular visits for assessments including clinical dementia rating scales, cognitive tests, daily living activities evaluation, and brain imaging biomarkers. Safety is monitored by tracking adverse events and serious adverse events. Blood samples are collected to measure VHB937 levels and immune responses. The total study duration includes the 72-week treatment period plus additional time in the extension phase.
