Summary
Evaluation of central nervous system penetration of orally administered Rapamune (RAPA) in older adults with Mild Cognitive Impairment (MCI) or early Alzheimer's disease (AD) and investigate associated safety, tolerability, target engagement, cognition, and functional status as initial proof-of-concept study
Eligibility Criteria
Inclusion Criteria
- Diagnosis of Mild Cognitive Impairment (MCI) or Alzheimer's disease, Global Clinical Dementia Rating Scale (CDR)=0.5-1
- Normal blood cell counts without clinically significant excursions; ; normal liver and renal function; and glucose control (HbA1c 200 or LDL cholesterol >193, or other abnormal labs deemed clinically significant upon investigator review
- Current or chronic history of pulmonary disease or abnormal pulse oximetry ( 160, diastolic BP>90mmHg)
- Active inflammatory, COVID-19, autoimmune, infectious, hepatic, gastrointestinal, malignant, and/or psychiatric disease
- History of, or Magnetic Resonance Imaging (MRI) positive for any space occupying lesion, including mass effect and/or abnormal intracranial pressure, which would indicate contraindication to lumbar puncture
- Organ transplant recipients
