Clinical Trial Summary

This single-center, uncontrolled pilot study aims to evaluate the efficacy, safety, and tolerability of six months of intermittently dosed oral rapamycin (sirolimus) in subjects with early-stage Alzheimer's disease. Fifteen participants will be recruited. Following a set of baseline measurements, all participants will receive a weekly oral dose of 7 mg rapamycin for six months. Participants will be continuously monitored for safety and side effects. At the termination of the treatment, follow-up measurements will be taken. The primary endpoint will be change in cerebral glucose metabolism, measured using 18F labeled fluorodeoxyglucose ([18F]FDG) positron emission tomography (PET). In addition to the registered outcome measures this pilot trial will explore the feasibility of acquiring data on the effect of sirolimus treatment on age-related tissue changes in the body using a variety of imaging modalities, such as bone mineral density assessed using quantitative computed tomography, retinal structures assessed using optical coherence tomography, periodontal tissue assessed using MRI and FDG-PET, cardiac function assessed using MRI, vessel wall in large arteries using MRI and [18F]FDG PET.
