Summary

This trial will study the effects of a 12-month oral rapamycin treatment in older adults with early stage Alzheimer's disease and amnestic mild cognitive impairment.

Who is the study for?
Adults aged 55-89 with mild cognitive impairment or early Alzheimer's, who have a representative to assist them and are on stable Alzheimer's medication. They must show amyloid presence in PET imaging, have normal organ function and blood counts, and controlled glucose levels. Excluded are those with recent severe illnesses, immunosuppressant use, untreated high triglycerides, heart issues, certain neurological conditions other than AD/MCI.
What is being tested?
The trial is testing the safety of rapamycin over a year in older adults with memory loss due to mild cognitive impairment or early Alzheimer's disease. Participants will either receive rapamycin or a placebo (a substance with no therapeutic effect) to compare outcomes.
What are the potential side effects?
Rapamycin may cause side effects such as increased risk of infections due to its immune-suppressing properties; it can also affect liver and kidney function tests, cholesterol levels (lipid panel), blood sugar control (HbA1c), and wound healing.
